Watch this  video and see how both Coke and Pepsi disguise the sale of thousands of tonnes of single use plastic. The Coke Experiment  


Plus 10 interesting facts about Aluminium cans

Both Coke and Pepsi promote their aluminium cans as being environmentally sustainable, but the plastic lining is not the only misleading environmental claim about these cans.

  • Worldwide an estimate 200 billion drinks cans are produced every year, that’s 167000 every second. Enough to encircle the Earth are produced every 17 hours.
  • The USA produces 100 billion of these beverage cans every year. Their manufacturer creates 8 million tonnes of greenhouse gas emissions.
  • As all carbonated drinks are acidic, with Cola being one of the most acidic, this acidity is due to both Phosphoric and Citric acid in the Coke drink formulation. Therefore, without the can’s protective polymer lining, the core would simply corrode the aluminium can. (What’s this do to our teeth?).
  • Aluminium is made from Bauxite, a sedimentary rock with a high aluminium content. The production of aluminium from Bauxite is one of the most Toxic, Polluting, Energy intensive manufacturing processes on the planet.
  • Aluminium Can manufacture is a two-stage process. The first stage uses electrolysis to melt the rock which produces aluminium oxide before stage 2, smelting to produce aluminium ingots. From these, sheets are formed from which the cans are manufactured. This process is so energy intensive that it consumes calculated to 3% of the world’s total energy supply.
  • For example, Australia produce just 2 million tonnes of the 65 million tonnes of aluminium produced annually worldwide, yet Alu manufacture is the largest energy user in Australia consuming 12% of the country’s total energy generation.
  • The residue from aluminium can manufacture is a red ‘sludge’ which, amongst other toxic ingredients contains heavy metals, silica and caustic soda. This toxic ‘sludge’ is stored permanently in ‘lakes’. In Hungary in 2010, leakage from one of these lakes killed 10 people and seriously injured 120 more with burns. Over 15sq miles of land was affected and the spill reached the Danube. 2.5 Billion tonnes of this toxic ‘sludge’ is currently stored worldwide to which we add 120 million tonnes every year.
  • Aluminium is infinitely recyclable by re-melting at a temperature of 600ﹾ Recycling uses only 5% of the energy required to produce virgin material as electrolysis is not required. However, even the re-melting of aluminium uses significant amounts of energy.
  • Around 70% of aluminium cans are recycled, which means 30% are incinerated or landfilled. In effect, as 200 billion cans are produced each year this means 60 billion cans per year Worldwide go through the whole toxic, energy, intensive atmosphere polluting process of manufacture never to be used again! This is environmental carnage which no one mentions when promoting aluminium can recycling.   
  • A recent report from the Green Alliance claimed if just 50% of the UK’s current usage of plastic water bottles were replaced with aluminium cans, 162,000 tonnes of toxic sludge would be produced, along with all the other adverse environmental factors noted, yet sales of water in aluminium cans have increased fivefold in the last 12 months due to ‘Plastic Paranoia’.


The concept that sustainability and re-use of materials is automatically good environmentally does not apply in the case of aluminium cans vs plastic bottles.

Any ‘Life Cycle Analysis’ needs to consider not just the ability to constantly recycle aluminium, but also the 60 billion aluminium cans ‘lost’ each year and the 2.5 billion tonnes of toxic ‘sludge’ currently being stored around the world.

Even if we managed to recycle 100% of all aluminium cans, we will still be adding to greenhouse gas emissions on re-melting and recycling. 

Finally, China is the world’s leading aluminium producer with 36 million T.P.A. (55%). This Alu is produced from fossil fuel, predominantly coal. Whilst here in the UK we are closing coal powered power stations as our contribution to reducing global warming. (You could not make this up!)

In March last year the Government announced its intention to levy a tax on Plastic Packaging. Whilst the tax is not proposed to be introduced until April 2022 and the consultation period for submissions closed in May 2019, there were a record number of 162,000 submissions of ‘Evidence’ to this consultation which are now under consideration. However, the wording of the request for information on this process from both the Treasury and Defra leave little doubt in the mind of the readers that this is a far from equitable ‘Consultation’.

For example, and I quote;

‘Using new plastic typically has greater environmental impact. It requires unnecessary resource extraction, with higher energy use and emissions than using recycled material!’.

‘The Government wants to encourage the sustained use of more recycled plastic in the production of plastic packaging to help tackle plastic waste!’. 

‘The tax will be set at a rate that provides a clear economic incentive for businesses to use recycled material in the production of plastic packaging!

Please note the words used;

  • There is an Unnecessary Extraction
  • Higher Energy User Emissions
  • The tax will be set
  • A clear Economic Incentive.

These words hardly suggest that those considering the 162,000 submissions are unbiased in their views. In fact, they suggest any submissions against the tax are a complete waste of time. Whilst the Treasury accept that the cost of recycled plastics would be higher, the implication in the wording is that the tax on Virgin material would be ‘sufficiently high’ to offset this cost differential. How high is ‘sufficiently high’ is anyone’s guess and best left to the imagination.   

The British Plastics Foundation (BPF) went to the expense of commissioning Ernst & Young,, to produce an evidence-based submission to be included in the consultation. This action was suitably denigrated by The Guardian as protectionism, nevertheless,  the whole proposal raises some interesting questions, for example;

  • There are over 400 local authorities in the UK, around 20 of which have the facilities to separate different plastics. So, where is the 600/700,000 tonne of plastic recyclate 30% going to come from to be included in the 2 million tonnes of plastic packaging, the Treasury says are currently used in the UK?
  • Who, if not the local authorities, is going to collect, separate and clean the plastic prior to recycling?
  • As around 90% of O.P.P and circa 40% of other films used in UK laminates are imported, will we simply be importing 30% of plastic foreign waste in these imported films?
  • Who will the Tax go to and for what will it be used?
  • Will the Tax be set off against the hundreds of millions of pounds currently being paid by the plastics industry for Packaging Recovery Notes (PRN’s)?
  • Will the Tax encourage the use of alternative materials regardless of any negative environmental impact?

What can we do to avoid the Tax?

Right now, we have access to an OPP film with 30% recycled content available for trialling. This is food grade film which has mechanical properties practically identical to virgin OPP. However, the film should be subject to machine trials which we can provide free of charge. There is a small premium cost of this OPP film once approved for supply, but it will enable customers to demonstrate that they are taking action to meet the concerns of the market re plastic packaging.   

30% Recycled PE and Laminated Films

We are currently working with key suppliers on trials of these films using 30% recycled material. We anticipate having some suitable film available for trialling either later this year or early 2020, so please watch this space.


Due to the current lack of post-consumer collection, separation and recycling facilities we believe that it will be difficult if not impossible to meet the Government’s target of Tax implementation by 2022, however, imposition of this tax (at least in part) seems inevitable. Pyrolysis could improve the availability of bulk post-consumer waste at a later date. But, the cost of film recycled by pyrolysis will be prohibitive.

As a consequence, I reiterate my view that energy from waste plants is by far the most cost effective and least environmentally damaging solution for dealing with most post-consumer plastic packaging waste. The exception to this approach may be plastic bottles which are relatively easy to sort and recycle and Countries such as Sweden have demonstrated that with a small deposit scheme 96% plastic bottle recycling rate can be achieved.  

Nevertheless, it is a fact that countries such as Holland, Japan in Scandinavia, Germany and even France, etc, all have much higher numbers of energy from waste plants than the UK serving their National Grid, it is also a fact that none of these countries could be called environmentally backward! The UK antagonism towards energy from waste plants is based on a false premise that somehow, we are losing a precious resource when incinerating post-consumer waste plastic, when the truth is we are simply recycling the material back into the energy source from where it originated. It’s probably nearer the truth that cash strapped local authorities are not prepared to invest in these multi-million-pound energy from waste plants on financial rather than environmental grounds and they probably just hope that the problem of plastic waste goes away.  

As ever I welcome your views on any of the points made.

Does this government care at all about Climate Change?

This was the first thought that I had when I was told that the latest price for a plastic PRN is now £450 per tonne.

For those uninitiated in the jargon, a plastic PRN is a Packaging Recovery Note which, 12 months ago, would have cost £62 per tonne and which would right now cost £450 per tonne.

This is a legal obligation and the tonnage charged depends on a calculation devised by the Environmental Agency. A plastic PRN is now more than double the cost of most virgin material and has reached a level which will see many companies in the plastic packaging industry losing money, others make closures, and some suffer bankruptcy!  Consider this, in 2018 a total of 932,670 PRN’s were issued for plastics, each of those are now £388 more expensive than Q1 2018. That is a tax increase over the next 12 months of at least £361,875,960.

Compare this £450 per tonne with the cost of PRN’s for alternative packaging and materials;

  • PRN’s for Paper are at £16.50 per tonne
  • PRN’s for Glass are at £22.00 per tonne
  • PRN’s for Aluminium are at £145 per tonne

All of these materials generate more CO2 emissions in their sourcing, manufacture, distribution, etc, than plastic. For example, according to the Northern Island Assembly, it takes four times as much energy to manufacture a paper bag compared to a plastic bag and creates 70% more polluted air. Whilst, the mining, crushing and smelting of aluminium is one of the most energy intensive and most polluting manufacturing processes on Earth.

It is difficult to think of any other product in the UK other than plastic which could be subjected to a 600% tax price increase without a public outcry for Government intervention to control the escalation in cost. However, such is the public’s current perception of plastic, particularly plastic packaging, the media will probably applaud this increase as an encouragement to the retailers and food manufacturers to change their packaging to alternative materials.

Whilst the environment agency is allegedly increasing its enforcement of Reprocessing accreditations for plastic, at £450 per tonne the generation of fraudulent plastic PRN’s is an invitation to criminals to join the recycling business.

It should be noted that the agency invariably does not prosecute those not complying with the scheme but usually just suspends their accreditation until the correct paperwork is available.

These PRN’s are designed as a tax on material manufacturers and distributors to ensure the UK meets its Recycling targets. In the case of Plastic, the current extortionate price simply reflects the UK Local Authorities long term lack of investment in plastic recycling and their willingness to simply export the problem to the third world. The decision by China to cease imports of waste plastic has shown how misguided this policy was.

We now have a situation where the escalating cost of supplying plastic packaging will force companies to consider the use of alternative materials which will undoubtably increase Climate Change.

All plastic packaging is capable of being recycled. The food manufactures and the food retailers all know this. They also understand that recycling plastic is the most environmentally beneficial and the most cost effective solution to its end of life treatment.  Unfortunately, none of them at the moment are prepared to make the case for using plastic packaging. Instead, they are appeasing the public by adopting environmentally inferior materials which are more expensive for plastic replacement. At some point this policy will have to be reversed as they know it creates more food waste. Meanwhile, those companies that supply plastic packaging in all its forms are being punished financially and vilified by the media.

As ever your views on any of the items included in these notes would be welcomed.

100% Recyclable Plastic

In theory the collection and sorting of the majority of plastic packaging waste is not technically difficult, it is a mechanical process which, if helped by some initial sorting by the customer, simply involves the separation of the waste by floatation or infrared spotting. This is followed by shredding and washing ready for re-use. (It would of course be made easier by providing the consumer with a ‘traffic light’ colour code on the packs to identify the different films).

So, what are the problems?

  • The resultant recyclate is often lower quality than virgin material, this has limited reuse.
  • The costs incurred in the process result in limited financial benefit when compared with virgin material.
  • Around 20% of plastic waste can not be recycled mechanically as it consists of lamination of different plastics such as PE, PET, PP and ALU, all are used in various combinations to increase food ‘shelf life’.

It is this third factor which is the most difficult to overcome but, after several years in development, the solution to recycling mixed plastics is now available, simply convert these waste plastics back into virgin quality feedstock!

You may have read elsewhere of this proposal, but we were recently visited by Adrian Howarth, marketing director of Swindon based Recycling Technologies, who didn’t take long to convince us that theirs is a totally practical solution to the problem of recycling mixed plastics and that the pilot plant can be economically upscaled to handle much higher volumes of mixed plastic waste. 

The major reasons this is possible are; 

a) The conversion technology utilizes pyrolysis. This is a long-established method used for producing charcoal or tar. 
b) The proposed recycling plants are not large multi-million-pound capital intensive installations but are built in ‘kit form’ off site then reassembled at the bulk recycling depot. 
c) As a consequence, no extra transport or waste separation is needed, plastic waste that can’t be recycled mechanically is recycled by pyrolysis back into virgin quality feedstock. 
d) Most importantly, the resultant recyclate which the company have called ‘Plaxx’ is a high value material which can be used to make wax, high-quality engine fuel for shipping, or quality feedstock for processing into plastic.

After many years of development on the Swindon site, the first large scale production facility is currently being assembled in Perth, Scotland, with a capacity of 7,000 tonnes per year. Whilst this may not appear to be a high volume at circa £3million per installation, they suggest 2 plants could accommodate mixed plastic waste from a population of approximately 300,000 people. 

In effect, this technology is ‘The Holy Grail’ as this will mean 100% of all plastic packaging will be recyclable and unlike the bulk recycled material ‘Plaxx’ will be a high value product.

Most of the major food retailers are interested in pursuing this solution to the problem of mixed plastic waste along with some of the large petro chemical polymer producers; 
The major reasons being is that anyone who takes the time and trouble to consider the reasons why we use plastic for food packaging realises that this is the perfect material for food preservation, transporting and presentation.

Plastic food packaging is light weight, low cost, inert and infinitely variable. Its detractors who promote plastic replacement with paper, board, glass or (heaven forbid) aluminium simply fail to recognise the negative environmental impact these materials have on the use of the Earth’s resources and the additional contribution their manufacture and transport make to global warming when compared to plastics.

‘It requires the whole supply chain to work together and focus on delivering solutions for the right reasons’

Plastic pollution has been in the spotlight since Sir David Attenborough’s shocking revelations in the final episode of his Blue Planet II series, aired in December 2017. It was impossible not to be moved by the images showing the damage plastic is doing to nature. Around the same time China, where the UK sent an estimated 55 per cent of paper and more than 25 per cent of plastic waste, banned the import of “foreign garbage”.

Humans produced an estimated 320 million tonnes of plastic in 2016, according to Surfers Against Sewage, and WWF says eight million tonnes of it is dumped into the oceans each year. With the prospect of mountains of plastic gathering in the UK and the emotive evidence of the terrible impact on the natural world that plastic has been having, it was unsurprising a strong movement to drive down the use of plastics developed. This prompted prime minister Theresa May to announce a “war on plastic” in her 25-year environmental plan, pledging to abolish waste such as carrier bags, food packaging and disposable plastic straws.

Are there unforeseen consequences to demonising plastic?

Eighteen months on from the Blue Planet effect and we are in the middle of government consultations on four key areas: extended producer responsibility, essentially focused on passing the cost of waste management of packaging to the producers of it; deposit return schemes for drinks containers; improving the consistency of recycling for households and businesses; and a plastic packaging tax. Change is afoot.

But policymaking does not always follow logic and its tendency towards fashionable issues, headlines and seemingly swift, decisive action has been known to result in unintentionally negative consequences. Think back to the government’s incentives to move towards diesel as a way to reduce CO2emissions, inadvertently resulting in an increase in nitrogen oxide emissions.

So, is change happening for the right reasons? Not according to some. Plastic, it turns out, is not evil. In fact, it has many positive social and environmental impacts on our lives. It extends the shelf life of food. It keeps transport costs down. David Bucknall, head of materials chemistry at Heriot-Watt University, warns that banning plastic would lead to much higher carbon emissions, the driver of climate change. And if there’s one issue that is hotter and more contentious than plastic, it’s climate change.

Authorities must have a holistic view of sustainability

Take the humble plastic shopping bag. The UK has reportedly seen an 80 per cent reduction in single-use carrier bags since the introduction of the 5p charge. It’s a great figure. But an environmental impact study by the Environment Agency, published in 2015, concluded that a cotton shopping bag would have to be used 173 times before its carbon emissions were lower than using new shopping bags. That level of reuse was described as ambitious by the report. And it highlights just one example where less plastic could mean higher carbon emissions.

So this is not a simple problem with a simple solution. Deciding which sustainability measure to use in policymaking is extremely difficult. Plastic use is top of the agenda at the moment and is currently a bigger consideration than carbon footprint. But there are other measures and, if we only consider food products, we could just as easily focus on food waste, food miles and water usage, to name just three. Focus too much on cutting any one of these measures and the others could shoot up.

It’s complicated. It’s challenging. It requires the whole supply chain, both for packaging and the product inside, to work together and focus on delivering solutions for the right reasons. Here’s hoping the current consultations will do just that.
