The Solid
Waste Association of North America (SWANA), January
30, 2003
This document
sets forth SWANA's strategy for significantly increasing
the rates of municipal solid waste reduction and recovery
in North America and makes a series of policy recommendations
that would remove barriers to and provide incentives
for achieving higher levels of waste reduction and recovery.
It is intended to be a living document designed
to communicate, stimulate discussion and solicit comments
on the ideas and concepts presented. Accordingly it
will be widely distributed to Federal, State and Provincial
legislators and policy-makers, local governmental officials,
solid waste management professionals, the media and
the general public. The document will be modified in
the future based on the commentary received.
In developing
this strategy, SWANA supports a comprehensive integrated
solid waste management approach that incorporates a
broad range of source-reduction, materials-recycling
and energy-recovery activities to reduce and recover
value from municipal solid wastes. SWANA believes that
there is significant opportunity to increase reduction
and recovery levels by working across the board and
encouraging reduction and recovery in many forms, wherever
it can be achieved in an environmentally and economically
sound manner. Furthermore, since there are technical,
economic and budgetary constraints to increasing waste
reduction and recovery levels, SWANA believes providing
a broad range of solid waste reduction and recovery
options will allow market forces to work to increase
reduction and recovery rates in the most economical
and efficient manner.
The
document first reviews the most recent US Environmental
Protection Agency data on solid waste-generation, recovery
and disposal along with the trends in these data over
the last two decades. Based on these data SWANA concludes
the following:
- Even though
the economy grew dramatically over the last decade,
the per-capita waste-generation rate has actually
leveled off and remained steady since 1990. This suggests
that waste generation continues to increase primarily
because the population is increasing and not because
of an inherent increase in wastefulness by consumers
and industry.
- The overall
reduction and recovery rate in 2000 was more than
50 percent when all forms of source reduction, recycling,
composting and energy recovery are included. In year
2000, 30 percent of the solid waste generated was
recycled or composted, 15 percent was recovered through
waste-to-energy systems, and waste generation was
reduced at the source by nearly 20 percent.
- Over the
last decade the quantity of municipal solid waste
disposed of in landfills has actually declined by
9 percent, even though the total waste generated has
increased due to population growth. This fact alone
testifies to the outstanding success of municipal
solid waste reduction and recovery programs in North
America.
The document
then presents several projections for future solid waste
reduction and recovery levels. SWANA concludes that
increasing the overall reduction and recovery rate to
65 percent over a 10-year period would be an ambitious
goal that would require a 28 percent increase in reduction
and recovery over current levels while holding per-capita
waste-generation rates level. This probably cannot be
achieved without new incentives to encourage across-the-board
increases in recovery and reduction levels.
The document
concludes with the following policy recommendations
that would build upon past successes and create incentives
to reduce waste and achieve higher levels of solid waste
recovery:
Recommendation
1: Encourage more extensive product stewardship
by product designers, manufacturers, retailers and consumers.
Recommendation
2: Expand efforts by Federal, State and Provincial
governments to develop markets for recycled materials
and recovered energy.
Recommendation
3: Provide financial incentives for investments
in recycling, composting and the use of recycled materials.
Recommendation
4: Include waste-to-energy and conversion technologies
in renewable portfolio standards and green power programs.
Recommendation
5: Encourage the recovery and use of landfill gas
by reinstating federal tax credits and through renewable
portfolio standards and green power programs.
Recommendation
6: Support technology transfer and research-and-development
efforts that have the potential to significantly increase
waste recovery rates, as well as work to reduce the
barriers to their implementation.
These recommendations
will provide the guiding principles for SWANA and its
members to use in advocacy efforts with policy-makers,
legislators, regulatory agencies, and industry and public
interest groups.
Introduction
This document
sets forth SWANA's strategy for significantly increasing
the rates of solid waste reduction and recovery in North
America. The heart of this strategy is a series of recommendations
for Federal, State and Provincial policy-makers that
SWANA believes will remove barriers to and provide incentives
for achieving higher levels of solid waste reduction
and recovery. In developing this strategy, SWANA supports
a broad definition of solid waste reduction and recovery
consistent with the practice of integrated solid waste
management. Integrated solid waste management involves
a series of complementary actions to reduce and recover
value from wastes through source reduction, reuse, product
stewardship, materials recycling, composting, anaerobic
digestion, conversion technologies, waste-to-energy,
landfill gas recovery and landfill mining. Integrated
solid waste management also involves the environmentally
sound management and landfill disposal of those wastes
that for technical or economic reasons cannot be eliminated
or recovered.
This broad
definition of solid waste reduction and recovery is
embraced for two primary reasons. First, SWANA believes
that there is significant opportunity to increase reduction
and recovery levels by working across the board and
encouraging reduction and recovery in many forms, wherever
it can be achieved in an environmentally and economically
sound manner. Rather than arguing which method of recovery
is better than the others, SWANA believes that a more
constructive approach would be to press forward on all
fronts and work to expand all of the options for reducing
and recovering value from municipal solid wastes. Secondly,
SWANA recognizes that there are technical, economic
and budgetary constraints to increasing waste reduction
and recovery levels and believes that local governments
should be provided with a wide range of reduction and
recovery options so that they can select what works
best for them based on their environmental, economic
and public policies and priorities. Providing a broad
range of solid waste reduction and recovery options
will allow market forces to work to increase reduction
and recovery rates in the most economical and efficient
manner.
In
the remainder of this paper, SWANA will first describe
the current and projected levels of solid waste reduction
and recovery and will then propose a series of policy
recommendations to expand the options for reducing the
quantities of and recovering value from municipal solid
wastes. These recommendations will provide the guiding
principles for SWANA and its members to use in advocacy
efforts with policy-makers, legislators, regulatory
agencies, and industry and public interest groups.
Current
Levels of Solid Waste Reduction and Recovery
A recently
issued EPA report, Municipal Solid Waste 2000 Facts
and Figures, presents the most recent data on the current
levels of solid waste reduction and recovery in the
US. (SWANA recognizes that there is currently neither
a national consensus on the definition of municipal
solid waste nor a universally accepted methodology used
to calculate the generation, recovery or disposal. Some
State and Provincial governments use different methodologies
and different definitions of solid waste. Also, other
organizations have developed surveys for various purposes.
In this document, SWANA uses the EPA data because it
has been consistently developed over a 30-year period
and is useful for tracking changes and trends.) While
only providing data for the US, a 1998 Waste Management
Industry Survey developed by Statistics Canada shows
that the situation is very similar in Canada. The EPA
data clearly documents how far we have come in recovering
value from municipal solid waste and in actually reducing
the amounts of solid waste being produced.
Chronicling
solid waste generation and recovery rates over the last
few decades, EPA finds that we currently recover value,
in terms of materials or energy, from more than 45 percent
of the municipal solid waste that is generated. In addition
we have actually reduced waste generation by nearly
20 percent. This results in a combined reduction and
recovery rate well in excess of 50 percent (See Table
1).

This is a
very important statistic that is not widely acknowledged
and is frequently overlooked in our discussions about
solid waste policy and in comparisons of practices in
North America with the rest of the world. Here's how
the EPA figures stack up. Waste
Generation and Source Reduction. In the US, about 232
million tons of municipal solid waste was generated
in 2000. However, according to EPA, 55 million tons
of waste were prevented or reduced at the source. Had
this not occurred, 20 percent more municipal solid waste
would have been generated. Waste reduction (sometimes
called source reduction) refers to actions taken to
prevent the generation of waste in the first place.
This 55 million ton reduction was accomplished through
changes in product designs to use less material, and
by changes in consumer practices that reduced the amount
of waste produced. The
EPA report also shows that, even though the economy
grew dramatically over the last decade, the per-capita
waste-generation rate has actually leveled off and has
remained steady at about 4.5 lbs. per person per day
since 1990. (Some States and Provinces include construction
and demolition material in the definition of municipal
solid waste. This results in a higher per-capita generation
rate than represented by the EPA data.) This suggests
that waste generation continues to increase primarily
because the population is increasing and not because
of an inherent increase in wastefulness by consumers
and industry.
Recycling
and Composting. The EPA report shows that 70 million
tons of municipal solid waste were recycled and composted
in 2000, which is up more than 110 percent from 33.2
million tons in 1990. This translates into a combined
recycling and composting rate of 30 percent of the waste
generated in 2000. Since total waste generation has
also increased over the last decade, we are now recycling
and composting a larger share of a bigger pie.
Energy
Recovery from Waste-to-Energy Facilities. In addition
to materials recycling and composting, the EPA report
indicates that about 15 percent of the municipal solid
waste generated was processed by combustion with energy
recovery. Waste-to-energy facilities are a clean, reliable
method of waste recovery and disposal. In the US, waste-to-energy
facilities process 34 million tons of solid waste each
year and generate 2,800 MW of renewable energy, which
is equivalent to the energy needs of 2.4 million homes.
Processing solid
waste through waste-to-energy facilities typically achieves
a 90 percent reduction in waste volume and a 75 percent
reduction in waste weight.
Landfills
and Landfill Gas Recovery and Utilization. Not included
in the above recovery percentages is the energy recovered
from solid waste disposed in landfills from which landfill
gas is collected and used as a fuel. Landfill gas, which
is 50% methane, can be used in various ways, including
to generate electricity or directly as a fuel supplementing
or replacing fossil fuels. According to data from the
EPA Landfill Methane Outreach Program (LMOP), the 360
existing landfill gas recovery projects nationwide currently
produce 1,200 MW of energy, which is the equivalent
of the energy needs of 1 million homes. SWANA believes
that landfill gas recovery and utilization should be
accounted for in the National statistics and that this
would result in even higher recovery percentages than
presented above.
One of the
most remarkable trends presented in the EPA report is
the significant decrease in the quantities of waste
landfilled over the last decade. In 1990 the quantity
of municipal solid waste landfilled was 140 million
tons. This quantity decreased to 128 million tons landfilled
in 2000, a decline of 9 percent. This means that even
though the total waste generated has increased due to
population growth, the quantities of waste sent to landfill
have actually declined. This fact alone testifies to
the outstanding success of municipal solid waste reduction
and recovery programs in North America.
The next
section of this document presents several projections
for future reduction and recovery levels.
What
Is a Reasonable Goal for Waste Reduction and Recovery?
It is very
important to have realistic expectations concerning
what can be achieved in waste reduction and recovery
in the short term (e.g. by 2010). Table 2 presents some
projections developed by SWANA using the EPA 2000 data
as a baseline.
The first
projection, entitled 2010 Status Quo,
assumes no increase or decrease in either the per-capita
waste-generation rate (4.5 lb./person-day) or the waste
recovery and reduction rate (55%) from 2000. This projection
assumes no deterioration of the current situation, where
industry and consumers would produce no more waste per
capita as in 2000 and that the only increase in waste
generation would be from population growth. It also
assumes that waste reduction and recovery quantities
would increase in proportion to waste generation in
order to achieve the same reduction and recovery percentages
of a larger total. Under this projection, the quantity
of waste reduced and recovered would have to increase
by 9 percent from 159 million tons in 2000 to 173 million
tons in 2010 just to keep up with the projected population
growth.

2010 Status
Quo: No increase in per-capita waste-generation
rates and same reduction and recovery rates as in 2000.
2010 at
65%: No increase in per-capita waste-generation
rates and a 65% reduction and recovery rate evenly applied
across the board.
The second
projection, entitled 2010 at 65%, assumes no
increase in the per-capita generation rate and an increase
in the recovery and reduction rate to 65%. Under this
scenario the quantity of waste reduction and recovery
would have to increase 28% from 159 million tons in
2000 to 203 million tons in 2010.
SWANA believes
that increasing the reduction and recovery rate to 65
percent by 2010 is an ambitious goal that will require
a 28 percent increase in reduction and recovery over
current levels while holding per-capita waste-generation
rates level. This probably cannot be achieved without
new incentives to encourage across-the-board increases
in recovery and reduction levels. At the end of this
report SWANA will propose a series of policy recommendations
that would provide such incentives. But before that,
the report will discuss the implications of attempting
to achieve even higher levels of solid waste reduction
and recovery.
Why Not
Eliminate Waste?
The EPA figures
provide an excellent perspective on proposals to completely
eliminate waste such as the zero waste approach recently
being promoted by various waste-reduction and recycling
advocates. The goal of the zero waste proposals is to
reduce waste to zero, or as close to zero as possible,
by minimizing excess consumption and maximizing the
recovery of wastes through recycling and composting.
It is this narrow focus on recycling and composting
that distinguishes this approach from SWANA's broader
approach of encouraging a wider range of source reduction
and material and energy recovery options. For example,
advocates of zero waste have actually opposed measures
that would increase the recovery of energy from solid
waste through establishing new waste-to-energy facilities,
operating landfills as bioreactors, and providing incentives
for landfill gas recovery and utilization. SWANA fully
supports the need for increasing recycling and composting
levels as important parts of integrated solid waste
management. However, SWANA also believes that significantly
higher reduction and recovery levels will only be achieved
through broader strategies encompassing a wider range
of approaches encompassing the recovery of both materials
and energy from solid wastes.
Table 3 presents
one scenario that illustrates the reduction and recovery
levels that would have to be achieved at an 85 percent
reduction and recovery rate in 2010.

Assumptions:
1. Waste-generation rates decrease to 4 lbs.
per person per day offset population increase
2. Waste Reduction and Recovery rate increases
to 85% with no increase in Waste-to -Energy
|
This scenario
assumes first that per-capita waste-generation rates
could be reduced to offset the effect of population
growth. This means that waste reduction would have to
increase by 45 percent from 55 million tons in 2000
to 80 million tons in 2010 so that the net waste generation
remained at the 2000 level of 232 million tons. Secondly
this scenario assumes that the overall waste reduction
and recovery rate could be increased to 85 percent through
increases in recycling and composting alone. This would
require a 117 percent increase in recycling and composting
levels over the 10-year period (from 70 million tons
of combined recycling and composting in 2000 to150 million
tons in 2010.)
This analysis
shows that until we can demonstrate that it is feasible
to reduce per-capita waste-generation rates to the point
that they at least offset the effect of population growth,
while at the same time double existing recycling and
composting rates, a strategy aimed at eliminating waste
is clearly unattainable. Furthermore, the economic implications
of such an approach need to be carefully considered.
Extraordinary efforts to reduce waste-generation rates
would have impacts on the economy and the consumption
of goods and products. Attempting to push recycling
and composting rates to unprecedented levels, especially
in the face of weak recycled material markets, may result
in diminishing returns and very high marginal costs.
Even if eliminating waste were a technically feasible
goal, it would likely be very expensive to achieve over
a 10-year period.
Based on
these considerations, SWANA believes that a broader
approach that encompasses a wider range of materials
and energy recovery from solid wastes is a better and
potentially more successful strategy for increasing
waste reduction and recovery levels. SWANA's approach
is very similar to the successful strategies that have
been used in Europe and Japan to increase recovery levels.
Many of these countries have put in place ambitious
programs for increasing product stewardship and recycling
and composting levels. However, the countries that have
made the greatest progress in recovering value from
solid waste have been those that have incorporated energy
recovery as part of their National strategies. In fact,
in several European countries more than 40 percent of
the municipal solid waste stream is processed through
waste-to-energy facilities.
SWANA concludes
that considerable quantities of municipal solid waste
are going to continue to be generated into the foreseeable
future, and it is imperative that we invest in the facilities
and systems to manage them in an economically and environmentally
sound manner. Working to eliminate waste can be a positive
step to the extent that it focuses attention on waste
reduction, encourages product stewardship and identifies
creative and practical means to reduce waste. But an
unrealistic goal also can be counterproductive if it
creates false expectations, drives up costs and discourages
investment in improvements in the waste management infrastructure.
Recommended
Actions to Increase Reduction and Recovery Levels
In general,
the analysis presented above show how far we have come
in North America over the last decade in increasing
our solid waste reduction and recovery levels. But more
can be done by building upon the past successes and
creating incentives to reduce waste and achieve higher
levels of recovery by implementing the following set
of five policy recommendations.
Recommendation
1: Encourage More Extensive Product Stewardship
by Product Designers, Manufacturers, Retailers and Consumers.
Product stewardship deals with the actions that
should be taken to provide for waste management of a
product at the end of its useful life. From a solid
waste management perspective, product stewardship involves:
- Actions
to improve the design and manufacture of products
to reduce the quantity or toxicity of product waste
and facilitate product reuse and recycling.
- Actions
to establish programs to collect, process and reuse
or recycle products when they are discarded.
SWANA's
Product Stewardship Policy, issued by its International
Board of Directors in 2001, focuses on those products
for which special handling, recycling, reuse or disposal
practices have been established that are above and beyond
the conventional solid waste management practices carried
out or arranged by local government. The SWANA policy
calls on product manufacturers to take on new responsibilities
to reduce the adverse impact of their products. However,
SWANA recognizes that all participants in a product
life cycle - including retailers, consumers and waste
managers - have important roles to play working in cooperation
with product manufacturers to develop the most workable
and cost-effective solutions. Government legislators
and regulators have the important role of establishing
policies and programs to encourage product stewardship.
SWANA
believes that the responsibility for reducing product
impacts should be shared among industry (designers,
manufacturers, and retailers of products), government,
waste managers and consumers. Voluntary stewardship
programs, similar to those being developed for electronics
products by the National Electronics Products Stewardship
Initiative (NEPSI) and through the National Carpet Recycling
Agreement should be established for a wider range of
consumer products to encourage waste reduction, recycling
and reuse. As a major association for solid waste professionals,
SWANA will continue to promote product stewardship in
our education, training and advocacy programs.
Recommendation
2: Expand Efforts by Federal, State and Provincial
Governments to Develop Markets for Recycled Materials
and Recovered Energy. Federal, State and
Provincial governments should take a leadership role
in the creation and development of markets for products
made from materials and energy derived from solid waste.
Markets and market development are all about the economics
of supply and demand. Currently, demand for recovered
materials is weak; there is too much supply and this
results in low prices. For example, the market price
for residential mixed waste paper at the end of 2002
was well below $4/ton for most of the country. At that
low price, it is extremely difficult to operate a cost-effective
mixed paper recycling program when you consider the
costs for collecting, handling, sorting, and transporting
the waste paper. Largely for that reason, curbside recycling
of mixed paper has not been included in residential
recycling programs in many jurisdictions. Emphasizing
the procurement of goods made from recycled material
is aimed at strengthening and increasing the demand
and markets for recyclable material.
Given the
regional, national and international scope of recycling
markets, market development needs to come from the top
down and is most effective when carried out at the Federal,
State and Provincial level. All governmental agencies
and departments should create preferential procurement
programs for products and energy derived from solid
waste. There are substantial opportunities for agencies
to procure a myriad of products containing recovered
materials including office supplies containing recycled
paper, landscaping materials containing compost and
renewable energy recovered through waste-to-energy and
landfill gas recovery systems. Actions by local jurisdictions
can supplement and complement those of the Federal,
State and Provincial agencies.
Recommendation
3: Provide Financial Incentives for Investments
in Recycling, Composting and the Use of Recovered Materials.There
are some indications that recycling may have hit a plateau.
With the depressed market for many recycled materials
and the under-developed market for compost, a number
of communities are questioning the economic viability
of their recycling programs. From a local government
perspective, recycling costs money and the sale of recycled
material often doesn't cover the costs of collecting
and processing it. The problem is that the benefits
of recycling and composting accrue globally while the
costs are borne locally.
Furthermore
there are some developments that could further increase
the cost of composting and recycling. For example, in
Southern California concerns over air emissions from
composting operations have led a major air district
to propose covering composting operations and venting
them to biofilters. If this type of compost management
were to be implemented nationally, the cost of composting
could rise dramatically.
Recycling
will reduce the need for and the costs of long term
care of landfills. These are very real costs and at
some point will fall squarely on future generations.
Recycling also reduces the adverse environmental impacts
of mining, harvesting and processing virgin raw materials
and significantly reduces the consumption of energy
in the form of coal, imported oil and natural gas. Recycling
and composting deliver real benefits. Unfortunately,
these are not benefits that can easily be quantified
and realized by local governments looking at the short-term
bottom line.
In order
to change the basic economics of recycling and composting,
it is imperative to deal with the basic policies that
influence decisions about material use. For decades,
virgin materials have benefited from a full range of
subsidies, tax incentives, depletion allowances, favorable
capital gains treatment and other policies to encourage
their development and use. These policies have supported
the development of a nationwide infrastructure to support
the use of virgin instead of recycled materials. It
is time for Federal, State and Provincial policy-makers
to level the economic playing field between these materials.
Policy options that should be considered include tax
credits for recycled material use, tax free bonds for
recycling and composting investments, modification of
virgin material subsidies, and other financial measures
for recycled materials that would create meaningful
incentives for recycling and composting.
As part of
this effort it is important to collect data on the full
costs and benefits of recycling as compared to the full
costs and benefits of landfill disposal so that the
appropriate incentive can level the economic playing
field in the most direct way possible. These measures
would enable local governments to keep and expand the
recycling and composting programs they offer, and establish
programs with greater breadth and sustainability.
Recommendation
4: Include Waste-to-Energy and Conversion Technologies
in Renewable Portfolio Standards and Green Power Programs.
EPA reports issued over the last year demonstrate
that capital improvements at waste-to-energy facilities,
resulting from the Clean Air Act regulations, ensure
that waste-to-energy is one of the cleanest sources
of power in the world. As EPA previously reported in
its Mercury Study Report to Congress, mercury emissions
from waste-to-energy plants have declined by more than
90 percent from 1995 levels. As a result, waste-to-energy
now accounts for less than 3 percent of the U.S. inventory
of industrial mercury emissions. EPA also acknowledges
that dioxin emissions from waste-to-energy plants had
been reduced so dramatically, that in 2002, waste-to-energy
would represent less than 1% of the known sources of
dioxin.
All of these
changes are a result of the significant financial investment
made by owners and operators of waste-to-energy facilities
in response to the Clean Air Act air maximum achievable
control technology (MACT) standards promulgated by the
Agency in 1995. Also, in accordance with the federal
law, waste-to-energy ash is tested under EPA's Toxicity
Characteristic Leaching Procedure, and years of testing
ash from every waste-to-energy facility in the country
has proven that the ash is not toxic and is safe for
disposal and reuse.
Based on
all of these significant environmental improvements,
policy-makers can feel confident in encouraging the
use of waste-to-energy as a clean renewable source of
energy.
In addition,
there are a number of new conversion technologies that
use thermal, chemical and biological processes to convert
solid wastes into industrial biochemicals and fuels.
Most of these conversion technologies are currently
at the laboratory or pilot stages of development with
very few commercial operations in the North America.
Uncertain markets and lack of economic incentives have
hampered the development of these technologies beyond
the pilot stage.
As Federal,
State and Provincial governments pass legislation deregulating
the electricity markets, they should establish Renewable
Portfolio Standards that will require electricity generators
to provide a certain percentage of their power from
renewable fuels and waste-to-energy and conversion technologies
should be given full credit as renewable energy supplies.
Similarly, as electrical generators offer consumers
the opportunity to purchase power from green sources,
waste-to-energy and conversion technologies should qualify
as green sources. Investment or energy production tax
credits for new waste to energy and conversion projects
also should be considered. These efforts as a whole
would expand the market opportunities for waste-to-energy
and conversion technologies and would provide incentives
for the construction of new facilities and expansion
of existing ones.
In addition,
barriers to implementation of new waste-to-energy and
conversion technologies need to be addressed. For example,
in some states landfill diversion credits are not allowed
for any waste-to-energy or conversion technologies.
This has inhibited development and application of new
technologies. To overcome these and similar obstacles,
legislators need to be educated as to the benefit of
these technologies and new laws passed recognizing waste-to-energy
and conversion technologies as legitimate landfill diversion
and recovery options.
Recommendation
5: Encourage the Recovery and Use of Landfill
Gas by Reinstating Federal Tax Credits and through Renewable
Portfolio Standards and Green Power Programs. A
federal tax credit should be provided to encourage the
collection and use of methane gas generated by the decomposition
of solid waste in landfills. The methane in landfill
gas is a renewable fuel and should be considered such
in Renewable Portfolio Standards and green power programs.
Methane is
also a potent greenhouse gas and each ton of landfill
methane captured and used is equivalent to capturing
or reducing 21 tons of carbon dioxide. EPA estimates
that the 360 existing landfill gas recovery projects
reduce the nation's greenhouse gas emissions by the
equivalent of 60 million tons of carbon dioxide per
year.
Most of the
360 landfill gas utilization projects currently operating
nationwide were made economically feasible by the previous
tax credit under Section 29 of the Internal Revenue
Code. However, since that credit expired in 1998, it
has been unavailable to encourage construction of new
landfill gas recovery projects and few have been planned
and constructed since that date. Thus, the installation
of the more than 600 potential new landfill gas recovery
projects identified by EPA depends on the availability
of another effective federal tax credit.
If 600 potential
landfill gas projects can be brought on line by a new
tax credit, they and the 360 existing projects alone
could achieve 8 to 10 percent of the greenhouse gas
reduction target that was proposed under the Kyoto protocol,
by voluntary means and without regulation.
The methane
in landfill gas can be collected and converted to electricity,
used directly as an industrial boiler fuel, used as
a clean-burning vehicle fuel, or used as a hydrogen
source for fuel cells. Landfill gas recovery projects
and waste-to-energy systems are often located in urban
areas allowing them to provide an additional benefit
as "distributed" power sources to help improve
the reliability of the region's power supply and reduce
transmission costs. These projects run on a steady long-term
supply of renewable fuel and therefore, can essentially
provide an uninterrupted source of electricity.
Recommendation
6: Support Technology Transfer and Research-and-Development
Efforts That Have the Potential to Significantly Increase
Waste Recovery Rates. There are a number
of promising new technologies that have significant
potential for increasing the recovery of materials and
energy from municipal solid wastes. There are also considerable
opportunities to improve existing recovery and recycling
efforts through improved management techniques and modification
of programs to increase convenience and efficiency.
While this list is not all inclusive, examples of these
technologies and techniques include:
- Management
systems that provide incentives for recycling through
pay-as-you-throw or variable rate programs.
- Approaches
that have the potential to lower the costs of collection
of recyclables while maintaining value and minimizing
residuals e.g. single stream and commingled collection.
- Well-designed
public education and information programs that provide
compelling and consistent messages to policy-makers
and citizens alike.
- Opportunities
to improve waste composting through techniques such
as source separation of residential and commercial
organic wastes and enclosed aerated composting systems
and developing new markets for compost in bioremediation
and other applications.
- New products
designed for ease of recycling and reuse or that increase
the use of recycled materials in their design.
- Administrative,
financial and operational innovations that improve
the overall economic efficiency of recycling, such
as green purchasing, full-cost accounting, and automated
collection services.
- Operating
landfills as bioreactors by adding and recirculating
liquids to increase methane recovery rates over shorter
periods of time. Bioreactor landfills through accelerated
waste biodegradation can also increase waste settlement
thereby extending landfill life and can reduce long
term care requirements through enhanced waste stabilization.
- Conversion
technologies that can convert wastes to industrial
chemicals and fuels through hydrolysis, anaerobic
digestion and gasification.
SWANA
believes that a program of research and development
on new technologies, along with a sustained effort to
transfer knowledge on management and other improvements
for existing recovery systems is very important to achieve
and maintain higher levels of solid waste recovery.
SWANA fully
supports EPA's efforts to encourage research and development
by allowing States to authorize research and development
at Subtitle D landfills and by establishing the Project
XL Program and application of Cooperative Research and
Development Agreements. SWANA encourages more extensive
R&D and technology transfer activities by Federal,
State and Provincial governments, universities and by
the private sector. SWANA's Applied Research Foundation
can play an important role in stimulation of needed
research in conjunction and cooperation with these other
entities. SWANA thorough its Specialty Symposia, Annual
Conference, workshops, training and certification programs
and publications will continue to disseminate this information
on a wide scale to its members and other solid waste
professionals.
