In
the UK we have had a reputation in recent years for
being reactive rather than proactive in this industry.
One of the
nice things about being elected to the presidency of
a professional institution is that it gives you the
opportunity and platform to express your ideas for the
progression of the industry.
I am an engineer
by profession and as a result I am particularly interested
in the development of technology, on a global scale,
to meet the needs of our industry now and well into
the future. As a starting position, I have proposed
that we look beyond our horizons and therefore identified
four horizons for consideration. I invite you to engage
in some free-range thinking.
Geography,
Business, Public Perception, and Time
Geographically, we need to look outward to the
international community. We need to learn about and
to influence the use and development of good practice.
We need to deliver sensible solutions to meet national
and international targets for dealing with the residue
of human living, compatible with the economic conditions
in the countries where the waste arises.
Believe me,
we are not alone. For every problem we face, someone
elsesomewhere among the 8 billion people on this
planetfaces the same. This is rapidly becoming
a truly international business.
We in the
UK have much to learn from the successes and failures
of new technology, practices, and discoveries from other
countries. Yet we are also years ahead of others, and,
with ever-increasing environmental awareness, this presents
the Chartered Institution of Wastes Management (CIWM)
with further opportunities to engage directly with professionals
in the business, like the members of SWANA, in many
overseas countries.
Virtually
all our recent legislation relating to how we should
deal with the residue of human existence has a global
perspectivelike climate changeand it emanates
from the European Union (EU).
Enlargement
of the EU earlier this year brought in 10 new member
states. This will undoubtedly change the way the European
Commission works and the style of its legislation. It
will also bring our UK institution tantalizing challenges,
as well as opportunities to influence, network, and
learn.
Global trading
in secondary materials and the international availability
of specialist treatment and disposal technologies has
a considerable influence on the markets our industry
serves.
Where the
expertise exists to meet the market demands at near-zero
risk to the environment, we should recognize that the
developed world has a responsibility to play a global
role and reappraise what is meant by the proximity principle.
Let us now
have a look at the business horizon for our industry.
What Will
our Business Be in the Future?
Undoubtedly, we will still be involved in environmental
preservation, but much more than that we will need to
be recognized as a mainstay of the resource business.
Not just considering material for which there is a current
market, but on a global scale, we will be involved in
the preservation of all types of non-renewable materials
and the sustainability of renewable resources, viewed
across their whole life cycle.
This needs
engagement with product designers; all types of manufacturers;
energy providers; the agricultural, arboricultural,
and horticultural industries; land-use planners; fossil
fuel industries; and many others.
Resource
efficiency means discarding less, and it is high time
to embrace waste prevention as part of the added value
business we are in. It is also well past the time when
we should be reclassifying discards as renewable resources,
non-renewable materials, potential energy-producing
resources, and materials that harbour a hazard requiring
removal from the environment.
We need to
recover as much non-renewable material from waste as
we can. We must also find the best options to extract
maximum value from the renewables we discard, and there
are really only two final options here:
1. Return
them to the soil from whence they came.
2. Recover the suns energy, which they store.
In the first
case, it is surely better to return them, as a part
of the natural cycle, as compost or digestate. In the
second, it makes sense to extract the energy from renewables
instead of using up fossil fuels, whose renewal is on
a time scale none of us can readily relate to.
Fossil fuels
are also the raw materials for many of the essential
plastic products we rely on for our current way of life.
Alternatives are already available, and we should support
them. But for the time being normal plastic
is a mainstay of our modern lives.
Meanwhile,
irrespective of the accuracy of the estimates of world
reserves of fossil fuels, we know that demand far outstrips
renewal. So, after we have recycled and reused as many
plastics as possible, should we not recover the energy
from plastics rather than discarding them to landfills?
When demand outstrips supply we wont have the
choice anyway. We dont want to be left regretting
our failure to act. So, perhaps we now need to reappraise
the use and generation of energy in the waste industry.
This will force a sea change in the way we perceive
wastes.
The Elimination
of the Term Wastes
The perception horizon is one of the most limiting
factors in making progress. We deal with several completely
separate sources of wastes with very different output
controls. The control of the waste output from any managed
businesspublic or private sectoris ultimately
in the hands of management. It is therefore reasonable
to expect progress in waste reduction, reuse, and recycling
here, driven by regulation, cost, and fiscal intervention.
The other
sector is post-consumer wastes from each and every one
of us as private citizens. Here, it is much harder to
make regulations, charges, and taxes work effectively.
Now here
is a heretical thought: Im going to suggest that
reducing post-consumer waste is not automatically a
good idea.
By way of
explanation, let me set you a challenge to name more
than five types of purchases made by you in the last
five years, items that you expect will outlive you.
Ill give you real estate as your starter. The
others appear at the end of the article.
- How much
of your income was spent on such purchases?
- What
happens to everything else that you bought?
It finishes
up as waste! Not necessarily in the country of origin,
but somewhere, it becomes waste, and not necessarily
after just a short useful life. But how many consumer
products have a life expectancy of more than 10 years?
Taking time
into account, as consumer spending has risen, so has
the quantity of post-consumer waste. At the moment,
the amount of post-consumer waste closely follows consumer
spending in the preceding five years.
The only
realistic way to reduce this waste is for everyone to
buy less (more than a touch of economic suicide) or
for people to buy less wasteful products (taking us
straight back into the design corner again). So what
are the other options open to us?
The best
we can achieve with recycling is an extension of the
life of the material. Some recycling is indefinite:
glass bottle to glass cullet to glass bottle, and on
and on. Some recycling is down-cyclingglass bottle
to glass filter medium to landfill. But, all recycling
reduces pressure on virgin resources, and we should
support it wherever whole life cycle costs are reduced.
Recycling
is usually, but not always, beneficial. But dont
let this heretical thought give you the impression that
diverting such waste from landfills is not a good idea.
The whole purpose in good resource management is to
discard less and then extract the maximum ecological
and economic value from the waste, once it is produced.
Differences
in Perception
Industry and government currently perceive the
quantity of waste we deal with on the basis of weight.
But the public sees post-consumer waste by volume.
In Ireland,
the government has taxed carrier bags, partly due to
their prevalence in litter, and partly due to the perception
that they are a significant element of waste. Being
a sad wastes management anorak, I have weighed carrier
bags. Average weight is 4 grams, or a quarter of a million
to a ton. If every UK citizen used two carrier bags
per day, we would use enough oil to move every private
car in the UK slightly less than 20 yards or sit in
a traffic jam for one minute. Should we forsake such
an efficient carrying system for such a small saving?
A newspaper,
on the other hand, weighs 120 grams. It has the energy
value of 15 carrier bags and a useful life of one day.
Recycling it loses 20% to waste, equivalent to the energy
value of three plastic carrier bags.
Both of these
materials, along with packaging, feature more highly
in the public perception of waste than a ton of bricks.
If we look
at the effect of landfill tax in the UK, rather more
tons of bricks have been diverted than have tons of
plastics or paper.
Economic
controls can be very effective, but they need careful
design to achieve the right effect and outcome.
To fully
appreciate the value in residual waste, perhaps we have
to remove low-calorific-value (CV) wastes from the mass
before considering the disposal options. Taking out
low-CV material dramatically improves the fuel potential
of residual wastes and should reduce its pollution potential
when burned.
The public
may well be very vocal in its opposition to waste to
energy. But the crunch is coming. Soon we may have to
choose whether or not we can afford to continue to use
our carsor endorse sensible energy policies and
better design that the environment can afford.
In the UK
we already have hugely ambitious targets for the diversion
of biodegradable materials from landfill. If we are
to have any hope of meeting these targets, now is the
time to propose the strategies and individual facilities
needed.
I make no
apology for being controversial. This article is supposed
to challenge you and make you think.
Waste has
only been a major problem since the cost of materials
became significantly cheaper than the cost of labour
in production of goods. But the problem has been increasing
relentlessly for the past 60 years, and all we have
done is react to the problem.
Now is the
time we need to be creating ideas for wastes management
in the near future and the medium to long terms (say
40-plus years). As a time horizon, that is one working
lifetime, and we tend to forget the rate of change.
We need to
let our imagination take root and reflect on where the
existing rate of progress will lead us in the future.
It is about learning about new practices from elsewhere
that we can adopt, adapt, and improve. We need to stimulate
ourselves to think how we will deal with what seems
an unstoppable increase in waste.
We are all
frantically coping with the here and now. In the UK
were trying to give up a heavy landfill habit,
but we are getting buried in the present.
With unprecedented
and sustained commitment by thousands in this industry,
we may reach our short-term targets but we need to consider
now how the forever commitment can be met.
It could
be said that wastes management is the most predictable
business there is besides funeral undertaking. The zero-waste
concept will not reduce the need for wastes to be managed
but may be fundamental in converting the residue of
life into a sustainable resource and thus go a long
way to eliminating landfills in the developed world.
In the meantime, we may encourage the use of properly
engineered landfills in the fast-developing nations
as an interim measure to affect large-scale environmental
improvement, rather than suffer the global effects of
uncontrolled dumping.
To achieve
our long-term goals we need to plan at least nationallyand,
better still, internationallyto be able to deliver
locally.
When sewage
became a major threat to life, we developed national
collection and treatment systems, now effective for
more than a century.
Waste now
presents the same sort of challenge. To face it we need
coordinated thinking and action. To help this, perhaps
now is the time to do some in-depth strategic planning.
That means identifying everything that needs to be done,
by whom, and with what powers and responsibilities,
and we need to be a part of this thinking. This should
cover everything from reliable and timely waste data
and research to focusing support and input to governments
in European and even global policy development.
Looking back,
the popular phrase of the 90s was integrated
wastes management. But what were we trying to
integrate? I submit that the process has to start at
the moment a material becomes surplus to requirements
and then follows a pre-planned route to its next use.
This starts with educating the producer and putting
in place the means of collection and delivery.
Looking forward,
educating industrial and commercial waste producers
is not only feasible but desirable. The CIWM has put
in place some means to do this with the waste awareness
certificate. But can we realistically expect to do the
same for post-consumer waste producers? We should collect
this waste in ways as simple and convenient as possible
for householders. People want to do the right thing
with their waste but need us to make it easy for them.
Looking
Even Further Forward
Heres a crazy dream. Lets look at a
typical urban property. Its input utilities are water,
electricity, gas, telecommunications, and road access
(for material deliveries and vehicular and mammalian
access).
Its output
services are surface-water drainage, sewage, and road
access (for disposal of discarded materials and vehicular
and mammalian exit).
We have six
separate underground connections from four separate
providers. They are usually located under the other
main utility, which is the road. Servicing them usually
means digging up the roadfrequently! Unless you
believe the end of the world is nigh, we can expect
this to continue into the infinite future. But does
that make sense?
Why dont
we plan for this future? Why dont we devise a
municipal duct to deliver all the services and provide
the disposal route for all the outputs, including wastes?
Each property could have its own segregated materials
disposal point serviced by a computer-controlled underground
conveyor system. This would remove all waste types in
sequence to batching points for bulk collection and
resource recovery. We have the technology now.
Im
told anecdotally that the period for urban renewal is
about 80 years. If we start now it could all be happening
underground by the end of the century. If you think
Im dafthow many people in 1904 thought that
you would be able to travel from London to New York
in under four hours, just two working lives later?
And if it
does sound like a crazy dreamwhat solutions do
you want to see in your working life, or in just 10
years time? We shouldnt underestimate what
can be achieved by the willing.
So I end
by urging us all to stop just coping. Lift your eyes
to the many horizonsgeographic, business, public
perception, timeand think beyond them.
Dare to
Dream
Dare to shape the future. If you have been racking
your brains in response to my challenge for those five
types of purchases that you expect will outlive you,
here are some suggestions: jewelryantiques, collectables,
and heirlooms, including wedding presents stored in
the loft for 30 years; quality furniture made from hardwoods;
fine art and sculpture; and three few have thought of
life insurance, financial investments, and tattoos.
