Sustainability Role of biodegradable plastics within a circular economy
The report identifies applications of biodegradable polymers which contribute towards achieving a circular economy and tackle the challenge of managing the EU’s waste.
“We are pleased to see that this report clearly identifies several beneficial application areas for biodegradable plastics even though this was not its original focus”, says Hasso von Pogrell, Managing Director of European Bioplastics (EUBP). “We also welcome the call for economic incentives to promote appropriate disposal behaviour as well as the need for further research that it highlights”, he adds.
Von Pogrell further comments: “The SAM report emphasises the advantages of applications from biodegradable plastics ‘where it is challenging to remove or collect a particular plastic product or its fragments from the environment after use’. Mulch films made from conventional plastics, for example, are widely used in European agriculture. The challenge of plastic accumulation in soil can be tackled with the soil-biodegradable alternative.”
EUBP was pleased to note that the report also highlights the benefits of biodegradable plastic products “where it is difficult to separate plastic from organic material that is destined for a composting waste stream or wastewater treatment”. Packaging highly contaminated with food scraps, cannot be mechanically recycled and will be incinerated or, even worse, landfilled. By using industrial compostable packaging, this contaminated waste fraction will not get lost as it can be included in the organic recycling stream. Additionally, it has been proven in several studies that industrially compostable biowaste bags significantly increase the capture rate of biowaste. However, EUBP agrees with the study authors that “the potential benefits of biodegradable plastics will only be realised if the formulation of the product is appropriate to the receiving environment, and if any potential for the item or its fragments to escape to a receiving environment in which it biodegrades more slowly, is minimised”. It is also important to highlight the report’s statement for an effective waste management infrastructure to assure proper management of biodegradable and compostable plastics.
The report is an important first step in considering scientific evidence on the biodegradability of certain plastics in the open environment. It also makes clear that a successful reduction of plastic waste and achieving a circular economy, requires ongoing efforts by all parts of the value chain, also including consumers, and national and regional authorities.
