Traditional wine bottle cork packaging

There’s nothing quite like the ‘pop’ of a cork exploding from a wine bottle when it’s opened is there? For me, although screw thread or rubber closures do the job, they don’t quite have the same emotional appeal. Well, for those of you who have a similar opinion (94% of wine drinkers according to a survey of 1500), you will be pleased to hear that there is research available to backup the sustainable credentials of cork and its continued use in wine bottles.

According to the Portuguese Cork Association (APCOR) there are 3 misconceptions regarding cork stoppers, that are highlighted in a recent Packaging News article:

1. Trees are NOT cut down in the production of cork – they are harvested in a sustainable manner. In fact harvesting, if managed properly, actually guarantees a trees survival.

2. Screw caps are NOT the most environmentally friendly closure, as cork is 100% natural and renewable and apparently uses 10 times less carbon dioxide (CO2) emissions than plastic stoppers and 24 times less than screw caps.

3. Corked wine is (allegedly) is NO MORE of an issue with natural cork than tainitng is with other closure systems (although this has been very carefully worded by APCOR).

Medical device packaging

Traditionally medical products, devices and their related packaging has been ’sidelined’ in much of the debate around the environment, where the major focus has been on retail products. However, it is estimated (Mulligan) that medical packaging contributes between 30% to 50% (or more) of the medical waste stream. There is a lot of work going on in the background, within the National Health Service (NHS) in the UK, and further afield globally, as healthcare practitioners are put under increasing pressure to ‘go green’, become more ’sustainable’ and reduce their ‘carbon footprint’.  These initiatives go right to the core of their infrastructure, looking at everything from operating theatre furniture and equipment, through to medical devices and all related packaging.

However, there are wider ramifications, as it apparent that these sustainability initiatives will also enable huge cost benefits, improved regulatory compliance, and enhanced corporate social responsibility (CSR) when done correctly. So no pressure then !

On the face of it, this looks like a huge and daunting task, but with the aid of modern modelling techniques, such as those used by Walmart and by Marks & Spencer (M&S) in their ‘Plan A’, data and issues can be quite easily ‘chunked-down’ into manageable bite-size segments. This can help prioritisation and enable ‘quick wins’ on the highest ‘value creating’ initiatives.

It is important that suppliers and medical device manufacturers think about these sweeping changes and, if not already doing so, start to design and develop medical devices & healthcare packaging to meet these more stringent requirements. Next-generation packaging must be: 1) easy to manufacture; 2) meet stringent regulatory requirements; 3) meet the needs of distributors, healthcare institutions, and medical practitioners; and 4) minimize impact on the environment.

Mulligan talks in greater detail about all of this in an interesting article ‘Using a Life Cycle Analysis approach in medical packaging‘ recently published on the Healthcare Packaging website. Have a read and let us know what 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

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

Research carried out among 1,001 shoppers for the Alliance for Beverage Cartons and the Environment (ACE) UK found that just 26% of consumers had heard of renewable materials being used in packaging, while 16% knew of the FSC chain of custody logo.

Although I’m aware that mixed material cartons are now collected at some supermarkets (in the UK), it seems to be ‘patchy’ to say the least. The Tetra pak website provides some useful information, but I for one am not convinced that widespread and adequate infrastructure is in place to process these once collected, what impact processing has on the environment and what real usage there is for the recovered materials afterwards. Tetra Pak state that materials can be “used in furniture, to generate energy or even separated out into pure aluminium and paraffin.” But I wonder how much of that actually happens?

Cartons may well state that “purchasing this FSC certified carton from Tetra Pak supports responsible forest management worldwide”, but there are no statements about the other materials that need to be separated.

So come on FSC, if you’d like to provide us with the relevant information so that we can all make an informed judgement as to the pros & cons, we (in the industry) can help you spread your message.

Via Simeon Goldstein, packagingnews.co.uk, 18 November 2009 Computer giant Dell has selected packaging made from bamboo as an alternative to the paper pulp, corrugated and expanded plastic packs to ship its laptops. The China-sourced bamboo is being used for the cushions that cradle the Dell Inspiron Mini 10 and 10v netbooks inside an outer box made from 25% post-consumer material.

Health-conscious consumers bananas are a welcome part of a convenience store’s offering. That is, until they turn brown. Which is why Del Monte developed a new plastic wrap for bananas that promises to more than double their shelf life by keeping out air and moisture. 7-Eleven has been trialling the second skin in 27 of its Dallas-area stores. If the trial is successful, the bananas-in-bags could be stocked in the majority of the chain’s 5,787 shops by early 2010.

From the perspective of consumer health that’s a thumbs up, but some have criticized the extra packaging as environmentally unsound. After all, bananas come wrapped in their own protective layer. Del Monte is looking to develop biodegradable packaging, but also stresses that the new plastic wrapper reduces the overall carbon footprint by enabling a reduction in deliveries. The company is also introducing specially packaged bananas in vending machines, underlining the wider context of increased consumer demand for food that’s both healthy and convenient. (Related: Vending machines for healthy food — Vending machines for farm produce.)
