The government recognises that innovation into biodegradable plastics could help reduce the environmental impacts of plastics if they are disposed of in the right way. However, this is often not the case. We are concerned that, in the absence of robust and comprehensive standards, claims about the biodegradability of plastic-based products cannot be verified leading to potential confusion in the market place, possible increased levels of consumption and potential environmental harm at the point of disposal.

In 2015, a government report concluded that existing biodegradable standards are only applicable to very specific conditions such as industrial composters.  A review of oxo-biodegradable plastics has also conducted by the Hazardous Substance Advisory Committee in 2019. This can be found on their website at: https://www.gov.uk/government/groups/hazardous-substances-advisory-committee

As a consequence of these concerns, the government published a call for evidence last year to help consider the development of product standards or certification criteria for bio-based, biodegradable, and compostable plastics as well as to better understand their effects on the environment and our current waste system. The call for evidence closed on the 14 October 2019 and we are currently analysing the responses received. We will publish a government response before the end of the year.
