Further to the article that we blogged last Monday ,it seems that some plastics marked as ‘degradable’ might not be as environmentally-friendly as consumers (or even experts) think, according to new Defra-funded research.A packaging solution to the Great Pacific Garbage soup?

The study, carried out by Loughborough University, examined the environmental effects of oxo-degradable plastics which are made from the most common types of plastic, but include small amounts of additives to make them degrade at an accelerated rate. In response to this report, the Co-operative (in the UK) is to drop oxo-degradable plastic bags.

Iain Ferguson, Environment Manager, The Co-operative Food has said that:  “(subsequent to the above) We have also launched the UK’s first home-compostable carrier bag, certified by the Association for Organic Recycling (and to EN 13432), which is accepted for food waste collections by a number of local authorities.”

Products made from compostable plastic are tested and able to bio-degrade within six months.

There is also an interesting & related article in Packaging News today which states that:

Apparently, oxo-degradable additive producer Symphony has issued a statement that described the report as the “latest salvo in the oxo- versus hydro-degradable war” and said the allegations were familiar to firms in the sector.

Symphony also said it would be making a full response in due course, but said: “It should be obvious that plastic which self-destructs at the end of its useful life, leaving no harmful residues, is better for the environment than normal or recycled plastic, which can lie or float around for decades.”

It is also interesting that the firm also claimed that Loughborough University had not undertaken any experiments itself and that it was concerned to find that that “two of the three assessors of the report were themselves engaged in bio-based plastics, which is a totally different discipline to oxo- biodegradable”.

The plot thickens………….What do you think?

Pacific rubbish soup

As many people know, there is a huge and ever-increasing mountain of rubbish growing in the middle of the Pacific, like a giant festering ’soup’, much of which consists of plastic packaging waste. This has had a massive knock-on affect in the  form of polluted beaches on islands throughout the South Pacific, such as the popular Kamilo beach in Hawaii.

A British company believe that they have a packaging remedy. Symphony Environmental has created a substance that can be added to plastic materials to speed up the degradation time from several decades to just a few months.

Apparently “The special additive, called d2w, is put into plastic products when they are being manufactured. It works by weakening the carbon bonds, lowering the material’s molecular weight and eventually causing a loss of strength. The plastic can be given a set lifespan, depending on what purpose it is ultimately intended for.”

The aim is to get bread bags for instance to degrade in a matter of weeks and other items, designed for a longer shelf-life to degrade over many months.

This sounds great in theory and clearly a lot of research has taken place since this company was set up in 1995. We are in favour of any initiatives that help reduce/manage packaging waste. However, there are a number of issues that need to be clarified and addressed (if they haven’t been already).

What happens when one freezes items such as bread, to extend shelf-life? Will the degradation process be retarded or halted? Many items, such as toiletry products are used way beyond their stated shelf life. Does that mean that these items could degrade in the cupboard whilst still in-use?

It is also interesting to note that there seems to be “stern opposition from rivals” as the “plastics industry is split into two camps”: There are those that back ‘oxy-biodegradable’ (like dw2) that breaks-down simply with contact with air and those that back ‘bio-degradable’, which require more specific conditions such as burial in the ground and elevated temperature, to work.

I’m not so sure that there is such a defined “split” within the industry and can see the merits and issues of both of these approaches and, in our  opinion, both should continue to be developed. In terms of ‘Oxy-biodegradable’, as I’ve already mentioned above, degradation before end of shelf-life/use is an issue and what happens if a product is, for instance, left in direct sunlight – will this alter the degradation time frame? As far as ‘Bio-degradable’ goes – it is my understanding that unless specific elevated temperatures are reached,  degradation will not commence. So, for it to work properly, industrial bio-degradation facilities are required  – these materials will not degrade properly in a normal household composting bin.

Michael Stephen of Symphony also talks about bio-producers  having convinced British farmers that “crop-based plastics are best” but that “this is wrong…because when they are recycled they give off methane”. On top of this there area a number of concerns with these products around the use of scarce food resources to make packaging.

All of these materials could also present a potential issue of contaminating ‘normal’ recycling waste if not clearly identified & managed properly and I’m not sure that this issue is being addressed. Chris Penfold

Packaging seems to have spent far to long now being demonised in the press, it’s nice to see an article in a main stream newspaper that actually defends packaging and it’s use to protect and prolong the shelf life of food.

Very interesting and thought provoking article by the New York Times.  Interestingly some of the comments below the article appear to have been submitted by individuals who haven’t read the article very carefully.

 

popeye spinach packaging polymers?

‘Vegetarian’ polymers seem to be on the increase with yet another innovative initiative that, this time, uses natural cress plant waste, which is combined with a variety of different polypropylene grades to produce a range of packaging materials to suit different types of products with a variety of finishes. Allegedly they are produced using significantly lower CO² emissions than ‘conventional’ plastics.

The material called ‘Agriplast’ has been developed by German bio manufacturing company Biowert, which sources the cress-based waste from farms in the immediate area around Brensbach, in southern Germany, where the factory is based.

This sounds like a really innovative initiative and the the project is a collaboration between German company AHA Kunstofftechnik and French-based packaging manufacturer Cosmeco, who have combined resources to develop this material for use, initially, in cosmetics packaging.

Rumour has it that use of spinach for this type of polymer project could be a next-step development, something that could potentially really increase material tensile properties and produce a product as strong as iron – but this has yet to be verified and Mr P.Peye was unavailable for comment LOL

I don’t want to belittle the progress that Kraft has made in reducing the weight of its packaging but you have to ask the question, how much of this reduction is due to the move from heavy glass jars to light weight laminated pouches? 

There is no doubt that this will have had a huge positive impact on there transportation footprint, which is great – but what about the end life of the laminate pouch?  I’m still waiting to be convinced that high temperature recycling of laminates is really the right way to go.  And what about the end consumer, how many of them know how or where to recycle laminate pouches compared to those that can and do easily recycle glass jars?

Great marketing story though. (Jane Bear)

Kraft Foods has revealed it has cut 68,000 tonnes of packaging from its products around the world in the past five years.  To read the full article visit packagingnews.co.uk

This appears to be coming as a surprise but the French government seem very keen on bringing environmental labelling on packaging into force by January 2011, that’s only 11 months away now, so not much time to implement any changes to existing product packaging. 

Whilst I understand the motives behind the French move and admire them for trying to make a difference I’m not sure this is the best way to encourage manufacturers to lower their environmental impact, I’d be interested to hear your opinions. (Jane Bear)

Interesting article  – within the Grenelle Law for the environment, the French government would like to make the labelling of a number of environmental indicators on certain products a legal requirement from January 2011.  For the full article visit cosmeticsdesign-europe

I find it hard to believe that heating material to 500 degrees celseus in order to ‘recycle’ it can be truely environmentally friendly.  Surely the amount of energy needed isn’t going to be offset by the materials that can be salvaged, particularly when you consider that more energy will be needed to reprocess the reclaimed materials as well.

This article by Josh Brooks shows that the technology is now there, but is it really the right way to go? (Jane)
