Examination of Witnesses (Questions 260-279)
Mr Rick Hindley, Dr Michael Pitts, Mr Will Savage
and Mr David Workman
22 JANUARY 2008
Q260 Baroness Sharp of Guildford:
The evidence we have just received on the whole indicated that
it was actually easier to design down waste in a situation when
it was new process innovation. Equally, it does appear on occasions
that the improvement and the management of waste are easier once
created rather than at reducing it in the first place. People
recognise that it is there when they have created it and then
they think about ways of reducing it. What sort of incentives
are there to encourage manufacturers to reduce the creation of
waste and are they meeting the business needs of both large and
small companies?
Mr Workman: As with any industry, profit is
the main driver. The average plant five years ago had a waste
costthis is non-glass wasteof about £120,000
a year. In many cases that has been reduced very significantly.
We have one major flat glass manufacturer who over the last five
years has reduced waste per employee by a factor of five. There
is another manufacturer which my Lord Chairman has been closely
associated with over the years who has halved the amount of waste
per tonne of product produced in the last five years. The drivers
have been commercial as well as environmental but they have had
significant benefits. Most major plants now are either operating
to, or are likely to become accredited to, ISO 14001, which is
the environmental system which we tend to use in our industry,
and that is bringing huge benefits.
Q261 Baroness Sharp of Guildford:
Something like ISO 14001 is actually a very effective incentive;
it is a sort of voluntary agreement. How important is other regulation?
Clearly EU regulation has had a big impact here as well.
Mr Workman: I think EU legislation has had more
of an effect on us in terms of post-consumer waste rather than
waste within factories. I think the waste within factories has
basically been brought down. If you look at glass waste, the efficiencies
within the factories now are running at 90-95 per cent, so there
is very little glass waste that comes from the process and that
waste, if we do create it, goes straight back into the furnace
again. Post-consumer waste is a completely different issue and
that is almost entirely driven by EU legislation. We could spend
hours talking about that one, but that is the main driver.
Q262 Baroness Sharp of Guildford:
We are focusing here specifically on waste from manufacturers.
Mr Savage: I would concur with that, my Lord
Chairman. In terms of aluminium, the End-of-Life Vehicle regulations
will have a major effect on the reduction of waste post-manufacturing.
Q263 Chairman: Mr Workman, you mentioned
my old parliamentary constituency hosted, and still hosts, Owens-Illinois,
the major bottle producers. I would imagine your own European
position would enable you to tell us how the British glass industry
fares in comparison to international comparators because this
is something that we are having a little bit of difficulty getting
evidence on at the moment, the performance of British manufacturing
in relation to our competitors. What has been your experience,
either the European one or comparing a company like Owens-Illinois?
I know it is an American one and it has a plant in Harlow.
Mr Workman: This is a bit of a moving feast.
The major international companies are very reluctant to give us
that sort of information. I am trying to ascertain that information
now purely on the basis of energy costs around the world because
we tend to find the cost structures vary. If you look at productivity
in terms of output per man, the UK and particularly the company
you referred to will be very high up on the global ladder. Certainly
in flat glass we have one of the most productive sites operating
in the UK anywhere in the world. Productivity levels generally
are very high in the UK. They have had to become that way because
of the increases in costs that we have had to absorb over recent
years.
Q264 Chairman: On waste and energy,
at the moment you have not been able to compile satisfactory statistics?
Mr Workman: Where the continentals, particularly
in Europe, benefit is that their post-consumer recycling rates
are higher than they are in the UK and there are significant energy
and CO2 savings for putting recycled glass into the furnace rather
than virgin batch. In Germany and the Netherlands overall glass
recycling rates are 90 per cent plus. In the UK we should hit
our 60 per cent level this year, but getting hold of what we call
cullet, which is post-consumer waste, is becoming a very real
issue for us. In fact, some of our manufacturers have to import
it from Europe because they cannot get hold of it from the UK.
Q265 Baroness Platt of Writtle: In
days gone by you got tuppence back on a bottle or a can. Why has
that gone? Should it come back?
Mr Workman: Every time I come to the House of
Commons or the House of Lords this is the most frequently asked
question that I get from Members. The answer is that the infrastructure
has changed in the UK. When I was a young lad and I first started
out selling in glass almost every town had its own dairy, its
own brewery, its own soft drinks company and they used to fill
and distribute locally. In today's world, if you take almost any
product, like Budweiser or Stella beer, they are only filled in
one or two plants in the country, so to build return containers
from Aberdeen to London on Budweiser you are looking at huge environmental
and commercial costs involved in doing that.
Q266 Baroness Platt of Writtle: What
about if the local authority did it instead of it going straight
back to the factory because the good local authorities are doing
recycling in a big way?
Mr Workman: If you are looking at a deposit
on packaging that is a slightly different issue than a deposit
on a piece of packaging that you take back to the retailer, which
is what I certainly remember happened when I was younger. If you
get into deposits on packaging then you are getting into the areas
of tax, which is something I know that one or two of our continental
cousins have looked at and even implemented, but we are not there
yet in the UK.
Mr Hindley: Just picking up on your point about
being paid for cans, that still does happen. We have a highly
successful Cash for Cans programme where charities and individuals
etc collect aluminium cans and they are paid at the intrinsic
value of just around a penny each.
Q267 Baroness Platt of Writtle: That
is not very well known, is it?
Mr Hindley: Sadly, it started in the mid-1980s
and at that time a penny a can was quite attractive to collectors,
but with the way things have developed in the UK it is not quite
as attractive and in the meantime local authorities have developed
kerbside collection programmes which are a more convenient option.
It still does exist. It is not of the scale that it used to be,
but we still do get probably 15 per cent of all the aluminium
cans collected in the UK coming through Cash for Cans programmes.
Q268 Baroness Platt of Writtle: That
is a very small percentage when you think that aluminium is infinitely
recyclable.
Mr Hindley: Absolutely. We currently recycle
48 per cent of all of the aluminium cans that are sold in the
UK and the vast majority is now coming through kerbside collections
by local authorities. The big untapped market is actually from
what we call the away from home area where cans are consumed when
people are at work or in leisure centres or indeed "on the
go", that is about 30,000 tonnes and that is the big untapped
market. Some of the things that we have been talking about today
will have an impact on encouraging businesses to set up programmes
to collect the cans which their workforce use.
Q269 Lord Methuen: Let us go back
to this subject of cullet. In your paper you say about the cullet
not being fit for purpose. When we go to our recycling place we
have one container for clear glass, brown glass and green glass.
I have heard it said that once they leave there they all get tipped
into the same lorry and muddled up. Is this the cause of the problem?
Mr Workman: It is a major issue. The good news
is that the overall recycling rate for glass has improved year
on year on year over the last ten years, but what is in decline
is the amount of glass that is coming back to the glass industry
for re-melt and the reason for that is that some local authorities
are collecting segregated colours and segregating glass but then
the companies who operate the collection systems are then mixing
them. The worst examples we have got are the wastes that come
out of the MRF, it is pretty terrible. If you talk to any material
stream they would say they experience exactly the same problem.
The only way that this waste can actually be used is either for
it to go into landfill or into aggregates for roads. The CO2 saving
for that is zero compared to the CO2 saving for re-melt which
is very significant.
Q270 Chairman: I did not quite catch
that word that you said.
Mr Workman: It is the Materials Recycling Facility,
the sorting centre in effect.
Mr Hindley: From an aluminium point of view,
the quality of the material that is collected through post-consumer
schemes is a real concern to us. The industry has invested millions
in Europe's only dedicated can-to-can facility in Warrington which
is run by Novelis and cost £28 million. Much of the material
collected in the UK currently through local authority schemes
goes to the sorting centres, MRFs, and has to be sorted again
before it can be processed through the recycling plant and there
are a couple of reasons for that. One is that we do not have sufficient
sorting capacity in the UK for all the material that has been
collected, so the plants we have are running at over the capacity
they were designed for. Secondly, with the way the contracts are
set up between the local authority and the waste management company
there is no incentive for the waste management company to produce
a clean quality product at the end because they make their money
out of the tonnage that goes through the front door of the plant.
So we have an inherent problem in the way our system has developed
which is causing contaminated material and makes it very difficult
to recycle.
Q271 Lord Crickhowell: I still do
not quite understand why the performance on the Continent and
Germany is so much better than ours. If it is largely because
the local authorities are making a bit of a mess of this --- I
find it quite extraordinary that they should collect bottles of
separate colours and then mix them up again. What action should
be taken to eliminate this obvious nonsense and get us up to the
same performance as our European competitors?
Mr Workman: What we have to remember is that
the waste legislation, particularly the packaging waste legislation
in this country was enacted well before the words climate change
dropped off everybody's lips. It was designed clearly to get waste
out of landfill. When you meet with local authorities they say,
"Yes, we fully understand your problem, but we've got targets
to meet. We've got political masters at local level who again
are anxious to avoid tax on landfill." Their primary objective
is to avoid landfill at all costs. What happens to the waste after
that seems to me to be immaterial to them. What needs to change
in my viewit is something that was talked about with the
last set of witnessesis that there needs to be some sort
of CO2 element put into our Waste Strategy in future. If climate
change is as big an issue as we are being led to believe it is,
waste itself has the potential to save an awful lot of CO2, particularly
in aluminium and in glass because we both have materials which
are in theory 100 per cent recyclable.
Q272 Lord Crickhowell: Waste is only
partly addressed rather at the tail end and in specimen trials.
We are reaching the final stage of the Climate Change Bill in
this House tomorrow when we have got a debate on waste as it happens.
This is an issue that you think needs to be pursued and in the
field of climate change and the legislation that follows from
that?
Mr Workman: Yes. It has a knock-on effect in
terms of our ability to achieve our targets under our Climate
Change Agreements. It could have a tremendous knock-on effect
in terms of the Emissions Trading System that is coming because
we are relying in our forecasts for the future on getting an increased
amount of glass back for recycling, not less. There is about a
20 per cent difference in energy usage by melting returned glass
as opposed to melting virgin raw material. So there are some bigger
issues here that might well affect the future viability of the
glass industry in the UK.
Q273 Lord Crickhowell: I might ask
you for an email brief by tomorrow afternoon on that!
Dr Pitts: I would like to follow up with two
points on that. The first one is the difference between us and
our European colleagues. For quite a while I lived in Austria
and the culture is very different on recycling. There are four
different types of recycling bins on the streets everywhere, outside
houses; they are very accessible. If you go to Vienna airport
and a lot of other airports throughout Europe you will probably
have noticed the four different types of colour coded bins for
recycling things such as aluminium cans and glass bottles. There
is a big difference, as you have heard, in the public attitude
and culture. Coming back to the point about resource efficiency,
there is a link between climate change and the use of any resource
because any resource has some associatedas it is sometimes
referred to"rucksack" with it. You probably know
that for every kilogram of aluminium that is processed you need
6 kilograms of bauxite. In other metals it is much, much higher.
We are rapidly running out of many of the most important minerals.
As a chemist, in 80 to 100 years' time a significant proportion
of the Periodic Table will not be available to us unless we start
to do a better job of capturing and reusing our resource.
Q274 Earl of Selborne: Are you confident
that this is a robust method of accounting for the carbon or is
there still some work to be done to get a standard procedure?
Mr Hindley: I think we are making good progress.
As everybody is probably aware, British Standards and the Carbon
Trust have recently published a draft standard which is part of
a process. We responded to that and we welcome the creation of
a standard because I think comparing carbon as with life-cycle
analysis is fraught with danger because there are so many different
ways it can be done. We are totally supportive of a standard being
developed and that standard should become, in our opinion, a European
if not a worldwide standard.
Q275 Earl of Selborne: But we are
not there yet, are we?
Mr Hindley: No. Work is progressing and we are
involved in dialogue on that.
Q276 Lord Lewis of Newnham: Is there
not a subsidiary problem there? Let us make the assumption that
you have got a reliable carbon standard that you can apply. It
does mean that if you are concerned with substances such as landfill
or incineration or something like that you are going to have to
have a pretty complete analysis of the material you are actually
putting into the landfill. You have got to know what the mixture
is so that you can allocate these figures to it and that puts
another dimension into the whole disposal procedure either by
incineration or by landfill.
Dr Pitts: This is a huge issue and one of the
main issues that we are tackling as a KTN, it is understanding
how you measure environmental impact in all its forms up and down
supply chains. There are life-cycle analysis standards out there
and they are tied to the ISO 14041 standard. We are involved in
projects within the European Union to further life-cycle analysis.
As in most cases, you have the academics wanting to make it more
complicated and more rigorous, therefore more expensive and more
time-consuming, and you have the industry saying let us make it
simpler and easier to measure this. It is a huge issue up and
down the supply chains being able to understand where the hotspots
are, a shared responsibility from people who are taking these
things out of the ground to the people who are putting it back
into the ground at the end in landfill or in burners. Everyone
has their part to play. In some cases the consumer is the one
who has the largest part of the impact; in other cases it is right
at the top end in mining or it could be in the manufacturing.
We need to understand where they are and have a shared responsibility
in how we tackle this. The big companies do very well at working
with their suppliers now. Some of them are working very hard to
educate them and gain the shared benefits from that.
Q277 Lord Methuen: What new sustainable
technologies are being developed within your sectors which might
help reduce waste?
Dr Pitts: On behalf of the chemistry using industry,
we see chemistry as one of the enabling technologies for solving
a lot of the issues, it is underpinning technology. We have many
examples on our `roadmap'. We have a sustainable technologies
roadmap on the Chemistry Innovation website which lists many different
examples in different sectors where sustainable technology or
green design principles have been applied. One of the most important
considerations when manufacturing a product or running a process
is to think about it on a life-cycle basis, think about the feedstocks
you are using including what we call "waste" and redesigning
the product or process, as it allows one of three Rs at the end-of-life:-
to reuse it, recycle it or remanufacture. A good example now is
with LCD TVs. There has been a huge boom in them lately which
of course means now there is a huge pile of Cathode-ray tube televisions
lying around. Within the LCD TVs there are extremely important
metals such as indium, which is predicted to run out within 15
years, which is a bit of a shame as indium is an important component
for modern solar cells. Also within them, because they need backlighting,
are mercury lamps, but because they are toxic they are sealed
in inside units so they are very hard to get to, which means for
recyclers it is not economical to get these out and recover the
mercury within them. One of the ways the chemical industry is
tackling this is with organic LED displays. I was pleased to read
only at the weekend in Stephen Fry's column that designers are
embracing organic LEDs in new mobile phones. Mobile phone manufacturers
are often the leaders in technology innovation nowadays, and are
starting to incorporate organic LED displays and use them as true
objects of beauty, which I think is roughly paraphrasing what
Stephen Fry had to say. Within our own industry, solvent use is
a huge problem. We spend a lot of money and a lot of energy making
very pure solvents, from non-renewable feedstocks in a lot of
cases, and at the end of the process burning them, which is not
economical and not useful. There are strong drivers to change
this, such as the volatile organic compounds legislation. There
are a lot of sustainable technologies around such as ionic liquids,
supercritical fluids, solvent-free processes and process intensification
and they are the kind of things you will see coming on-stream
in the chemicals industry in years to come.
Q278 Lord Lewis of Newnham: Do you
not think you are going to be open to legislation? Many of the
things you are talking about are not specific; you have alternatives
available to you. If you look at many of the instances you have
been mentioning here, all right, you may have indium there and
it may be a desirable, but there are other ways of dealing with
this particular problem. It does strike me that at some stage
or other somebody is going to have to sit back and assess what
is going to be the long-term priority here and legislate accordingly.
Dr Pitts: Absolutely. We are going to run out
of important minerals and once an element has gone, it is gone,
and irreplaceable. We will be increasingly mining our own landfill
sites in the future.
Mr Savage: My Lord Chairman, the question was
about sustainable technologies. I just wanted to highlight a very
interesting development that has come out of the USA in terms
of recycling more aluminium and this is the introduction of de-lacquering
plants. Traditionally the aluminium bottle tops of beer bottles
have been put to landfill because they are relatively small, a
large surface area to smallish volume and they have a plastic
component which is part of the seal. There is a very interesting
technology now which is being introduced which actually allows
for the plastic component of the bottle top, the seal, to be burnt
off in the process, providing the heat for the recycling of the
aluminium bottle tops. These sorts of technologies are very interesting
and should be promoted to our industry.
Q279 Lord Methuen: Something that
has fascinated me is that we are now being asked to recycle our
drinks cartons, these tetra packs. I understand that some of them
have an aluminium lining. What is the energy balance of recovering
the aluminium because presumably you have got to separate the
aluminium from the paper of the carton by burning or have you
got some other more sophisticated process?
Mr Hindley: I do not have a great understanding
of this. You are quite right, all cartons have a very thin aluminium
lining which is a barrier there and that is very, very thin, it
is sprayed on. The carton industry is now encouraging people to
collect cartons for recycling. Sadly there is not a plant in the
UK that can do it. There used to be one up in Scotland which is
now closed. The material that is collected in the UK is actually
sent to Sweden for reprocessing. The aluminium is not recovered
because I understand it is not commercially viable to do so. So
the aluminiumand I do not know the process in detailis
removed, landfilled and then the board is then pulped and goes
back into the paper processing facility. This is a perfect example
of materials which are either composites or laminates so contain
a number of different materials that are inherently difficult
to recycle. Obviously we sell aluminium into that product, but
there are examples of where very simple packaging formats involving
metals are potentially going to be substituted by composites and
the reason for that has been the desire of retailers, driven through
organisations like WRAP, to minimise the weight of their packaging,
which is a laudable thing to do, but the weight of packaging is
only one element that should be taken into account when considering
sustainability. If you are moving from something which is infinitely
recyclable, a metal, to something which is a laminate, which is
very difficult to recycle, you are having a positive environmental
impact potentially by reducing the weight but creating more of
a problem by moving into something which is very difficult and
energy intensive to recycle. Another example of that can be seen
from an aluminium point of view in the aluminium foil container
which is used for takeaway meals or, increasingly by supermarkets,
for chilled meals. There has been a move away from aluminium into
something which is called CPET, which is a form of plastic, because
again it is lighter weight. The reality is that the foil container
is infinitely recyclable whereas the CPET container is very difficult
to recycle. So again something that has been driven by the desire
to reduce weight is actually perhaps not having an overall positive
impact on the environment. We are very cautious about the approach
that has been taken and very keen that a whole series of environmental
factors should be taken into account by retailers and others before
decisions are made.
Mr Workman: We are probably more vulnerable
than any other packaging material in this regard because we are
the heaviest, but we are seeing a move now by the retail trade
in the UK to replace glass with all sorts of other types of materials.
Glass is 100 per cent infinitely recyclable, not just once, it
can be recycled time and time and time again and the infrastructure
exists in the UK to handle it. We have been doing it since 1977
and very successfully. You have solved one problem but you then
potentially create another one, and this has been an initiative
that is being led by the retailers at the moment.
Mr Savage: On my point about the aluminium content
in plastic containers, yes, a lot of it is lost through oxidation,
it is a metallurgical fact in incinerators, but there is work
being done now to look at the aluminium and other metallic content
of fly ash in incinerators and the intrinsic value of aluminium
is forcing that situation.
Lord Crickhowell: Let us move on to challenges
that inhibit businesses within the aluminium, glass and chemicals
sectors from implementing waste reduction strategies. We have
already touched on some of them in the answers we have had to
previous questions. I want to pick up one particular one and that
was the reference to food packaging being infinitely recyclable,
but it is not being recycled. The evidence I have in front of
me is that 90,000 tonnes of aluminium packaging is going to landfill.
Alupro tell us in the evidence that one of the problems is that
we have 400 local authorities all with different policies and
we have got back to the weight issue again. I deal with the household
rubbish and I put all my bottles in one container and all my paper
in the other and quite large quantities of this aluminium goes
into the general rubbish bin because nobody is interested in it.
Baroness Platt of Writtle: Ours is collected
with the bottles.
