With the overwhelming amount of plastic waste being disposed into the oceans on a daily basis and the growing knowledge of this polluting the environment, some of the leading manufacturers have tried to combat this issue in the last decade by producing products with eco plastic. By developing lightweight plastic products that are supposed to break down rapidly, thus attempting to reduce the hazards to marine animals. However these so-called âbiodegradable plasticsâ arenât the answer, according to the United Nationsâ top environmental scientist, because they donât behave as promised. Instead, the âgreenerâ plastics contribute to the problem of ocean plastic just as much as other varieties.
Jacqueline McGlade, chief scientist at the UN Environment Program, warns that biodegradable plastics are not the answer to the problem of ocean plastic. âItâs well-intentioned but wrong. A lot of plastics labelled biodegradable, like shopping bags, will only break down in temperatures of 50C (122F) and that is not the ocean. They are also not buoyant, so theyâre going to sink, so theyâre not going to be exposed to UV and break down,â she told the Guardian.
I find it ironic that the very items that are supposedly designed to protect the environment are destroying it, such as captured within this image. While the rest of the plastic has broken into smaller pieces ( which is far from ideal and extremely deadly for marine life), the one bottle that hasn’t the slightest indication of beginning to biodegrade is the one purposefully created to! As you will find in the research below, these biodegradable plastics are not up to the standards they are perceived to have.
Previous studies have shown that biodegradable plastic products do not break down more rapidly in landfills, now a United Nations Report issued in May 2016 outlines how these supposedly biodegradable plastics are not actually any different from normal plastics when placed in to the sea, in fact they may have worse environmental effects.
Ironically, some of the additives used to make plastic more likely to biodegrade also make it more difficult to recycle. This means the âgreenâ product can actually pose more of a threat to the environment than other types of plastic.
âWhen you start adding all of that [additives], when it becomes waste, they [the additives] become the enemy of the environment. As consumers we need to think of the use of plastic,â McGlade said.
Furthermore, in a recent UNEP report it was concluded that the adoption of products labelled as âbiodegradableâor âoxo-degradableâ would not bring about a significant decrease either in the quantity of plastic entering the ocean or the risk of physical and chemical impacts on the marine environment, on the balance of current scientific evidence (UNEP 2015(a)).
