Eco footprints stamping on good intentions

Shops large and small far and wide are pontificating to allabout how green they are and how many rainforests they are saving buy flogging their new "eco" products to us. Whole companies have sprung up dedicated solely to supplying us with green merchandise, telling us on how to live our lives, and by chance selling the eco products we must have in order to avoid destruction.

It is truly amazing just how many companies are singly handedly saving us from ourselves and our nasty consumerism, boo, hiss.

Trading on ones green concepts, particularly when there are none is pretty bad form methinks and I feel many shops are simply not thinking about the consequences of their actions when switching from one product to another, only caring about marketing themselves as a green, ethical company.

One of the most popular "eco" products to be marketed in this way are Poly Lactic Acid lined paper coffee cup offered by catering supplies firms, coffee chains and supermarkets.

Polylactide is a aliphatic polyester derived from "renewable resources" (I use the term loosely), such as corn starch (U.S.) or sugarcanes (rest of world). Although PLA has been around for a while, it has only been of commercial interest in recent years, in light of its biodegradability.

As well as being used to line the inside of paper cups instead of the plastic lining normally used PLA is in use in plastic cups, plastic cutlery, carrier bags, food packaging, all manner of catering disposables and even nappies.

These new "biodegradable" paper cups are now one of the most popular green products as we all try in our own little way to stop global warming.

One of the biggest problems associated with these new Poly Lactic Acid lined paper coffee cup being used at lots of stores and coffee chains all over the planet is that customers are thinking they will biodegrade in their trash when they need to be sent to composting facilities or put in your compost at home, planted individuallyand covered by nice warm compost. If these paper cups are simply trashed they decompose at the same rate as oil based plastic lined paper coffee cups, that is years and years

Unless individuals compost all their biodegradable cups at home (assuming they are aware they have been given one) there will now be two types of paper cups requiring sorting at waste reclamation centres whereas in the past all waste paper cups could be easily sent for recycling without having to separate them.

Moreover once these new paper cups find their way into normal recycling channels (and you cannot tell the difference) it will ruin the entire recycling batch as normal plastic lining on normal paper cups and the starch based natural lining on the biodegradable cups does not mix well. You get the oil on water scenario.

Most companies manufacturing, marketing or using these products also seem not to have thought about what was removed from the earth in order to grow crops to make this natural product. Like bio fuels fields once used for production of food is now being used for crops to grow alternatives to plastics and petrol. There are even reports of forests being felled in order to make space to grow the sugar cane plants. This contributes to increases in food prices, the result of which most will have noticed over the past 12 months. There will never be enough available space to fully change over from our dependence on plastics to enable us to move to growing this naturally produced alternative, everybody would starve.

On the subject of starving people one other factor to consider regarding these new  Poly Lactic Acid plastic products is that we have spent a long time giving subsidies to farmers in Africa to assist them create crops and stand on their own two feet. Many of the crops these farmers are harvesting are corn or sugarcane.

As we are now mass producing those same crops for Bio Fuel and alternatives to plastics, lowering the prices, plunging these people back into poverty.

There are alternatives that given a little more thought could do many of the jobs these companies hope to achieve through their use of Poly Lactic Acid lined or produced cups. Oxo-biodegradable Plastic (OBP's) for example are normal plastics such as polypropylene (PP), polystyrene (PS) and polyethylene (PE) to which is added a mixture (d2w additive) that accelerates the decomposition of the chemical structure of the material.

Oxo-biodegradable Plasticswill degrade, then biodegrade, on land or at sea, in the light or the dark, in heat or cold, at a pre-determined rate, leaving no fragments, giving off no methane and leaving no harmful residues.

The resultant broken down products are then amenable to conversion by micro-organisms, for which these products are food and also into carbon dioxide and water; thereby returning otherwise intractable plastics to the ecosystem.

These Oxo-biodegradable Plastics can now have a shelf life, pre-determined when manufactured Utilising oxo-biodegradable plastics does not prevent them from being recycled.

Sadly there are many more stories like this, such as the major burger house that dropped its plastic coffee stirrers and switched to wooden stirrers in an effort at greening their company. Out of fear of lawsuits from customers for getting wooden splinters in customers mouths with their wood stirrers they insisted that they are covered with gelatin (like your prescription pills). Adding this extra process to the production of the stirrers costs a lot of energy, to the point where the natural product becomes more energy intensive than simply using plastic. Another classic greening was the banks saving acres of rainforest by using green bank accounts which use paperless statements, an idea I learned about from a paper flyer and noticed advertised on billboard advertisements.

Plastics are not "evil" as many would have you think, reducing our dependence on it is a good idea however we cannot just replace all plastic with a seemingly greener alternative without considering all the repercussions, and definitely not just to be seen to be greening your company
