In 2015, a Government report concluded that existing biodegradable standards are only applicable to very specific conditions such as industrial composters. We are concerned that, in the absence of robust standards, claims about the biodegradability of plastic-based products cannot be verified leading to potential confusion in the marketplace, possible increased levels of consumption and potential environmental harm at the point of disposal.

Furthermore, in line with the advice received from the Hazardous Substances Advisory Committee and as set out in the Resources and Waste Strategy, the Government’s focus is on encouraging increased reuse and recycling of products and materials, to extract maximum value from them, in line with our ambition to transition to a circular economy. This being said, 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. If mistakenly recycled with other plastics, they have the potential to damage the quality of the new products made from the recycled plastic. Furthermore, concerns persist that plastics which are claimed to be biodegradable, if littered or otherwise released into the environment in an uncontrolled way, may not degrade quickly or at all, and they can only be composted if they meet relevant standards and are treated in line with those standards.

As a consequence of these concerns, the Government published a call for evidence in 2019 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 is now closed and we are currently analysing the responses received; we will publish a Government response shortly.

While biodegradable materials may be seen as a solution to reduce the impact of waste, they can also be more environmentally damaging than non-biodegradable materials if disposed of incorrectly. The Government is also concerned that, in the absence of robust standards, claims about the biodegradability of plastic-based products cannot be verified.

In order to consider impacts carefully, Defra and the Department for Business, Energy and Industrial Strategy published a call for evidence to help us consider the development of standards or certification criteria for bio-based, biodegradable, and compostable plastics, and to better understand their effects on the environment and our current waste system. We are currently analysing responses to the call for evidence with a view to publication of a government response shortly.

In January 2017, the European Commission asked the European Chemicals Agency (ECHA) to prepare an Annex XV restriction dossier concerning the placing on the market and use of oxo-degradable plastics. However, ECHA withdrew its intention to prepare the dossier in May 2019, on request from the European Commission, following the inclusion of oxo-degradable plastics in the Single-Use Plastics Directive.

This information can be found at: https://echa.europa.eu/registry-of-restriction-intentions/-/dislist/details/0b0236e18244d9bb.

This decision was a matter for the European Commission and it would not be appropriate to comment on an investigation which was not completed.

It is current practice in science for research to be published in international peer reviewed journals. The peer review process is central to quality assurance and ensures reliable and reproducible research findings enter the public domain and inform debate.

We would be happy to review the data once it has undergone peer review and has been published.

As stated in the Answer of 12 November 2020 to Question 113024 on plastics recycling, the Government published a call for evidence in July 2019 to help consider the development of 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 further considered existing standards including BS EN13432. We are currently analysing the responses received to inform future policy and will publish a response to the call for evidence shortly.

As stated previously in the Answer of 12 November 2020 to Question 113020 on Plastics: Pollution, our priority is to prevent plastic entering the environment at all, including through littering, with a focus on upstream measures to turn off the tap on plastic pollution. The Government’s Resources and Waste Strategy sets out our plans to move away from a take, make, use, throw society to one where materials are kept in circulation for longer. It also commits to eliminating avoidable plastic waste over the lifetime of the 25 Year Environment Plan. Our Litter Strategy sets out our aim to deliver a substantial reduction in litter and littering behaviour within a generation. Littering of any materials, including biodegradable plastics, is a criminal offence, and councils have legal powers to take enforcement action against offenders.

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 14 October 2019 and we are currently analysing the responses received. We will publish a Government response shortly.

My answer was given in response to my Rt Hon Friend’s question about European Standard EN 13432, PQ UIN 113024.

As stated in the Answer of 12 November 2020 to Question 113023, the Government published a call for evidence in July 2019 to help consider the development of 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 further considered existing standards, which includes BS EN13432, BS 8472, and ASTM D6954. We are currently analysing the responses received to inform future policy and will publish a response to the call for evidence shortly.

As I outlined previously, I appreciate the engagement of industry in our call for evidence and welcome further engagement in future consultations and policy development as our work develops.

EN 13432:2000 is an industry-derived harmonised EU standard which lays down minimum requirements for packaging recoverable through composting and biodegradation. It is a standard that has been adopted by national standards bodies in many of the EU Member States. In the UK it is published as BS EN 13432 by the British Standards Institution. Only packaging which has passed relevant tests and assessments can carry the standard. It has not been adopted into UK legislation.

Turning to standards and biodegradability more broadly, we are concerned that, in the absence of robust 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. Furthermore, concerns persist that plastics which are claimed to be biodegradable, if littered or otherwise released into the environment in an uncontrolled way, may not degrade quickly or at all, and they can only be composted if they meet relevant standards.

As a consequence of these concerns, the Government published a call for evidence in July 2019 to help consider the development of 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 14 October 2019 and we are grateful for the responses submitted to us by industry and others. We are currently analysing the responses received to inform future policy and will publish a response to the call for evidence by the end of the year.

We appreciate the engagement of industry in the call for evidence and welcome further engagement in future consultations and policy development as our work develops.

The Hazardous Substances Advisory Committee is an independent scientific advisory committee. We tasked them to conduct a literature review of the published scientific literature. Stakeholder engagement was therefore not part of this process.

The Government’s 25 Year Environment Plan sets out our ambition to eliminate all avoidable plastic waste. Our priority is preventing plastic from entering the marine or terrestrial environment, and our focus is on creating a circular economy. The UK is recycling more than ever, achieving a 46% plastic packaging recycling rate in 2017, and the Government is committed to minimising the movement of waste for disposal elsewhere. Through our Resources & Waste Strategy we have committed to take action to help stimulate investment in domestic reprocessing and recycling infrastructure. This includes through new policies such as extended producer responsibility and deposit return schemes for drinks containers (subject to further evidence and analysis); raising recycling targets for packaging across a number of materials and waste streams to increase the amount and quality of recycling and improve environmental outcomes.

The Government does not hold data that differentiates between non-biodegradable and biodegradable plastic litter. However, the UK does collect data on the quantity and type of marine litter in our waters, including data on seafloor litter, floating litter and beach litter, following methods agreed through the OSPAR Convention’s monitoring and assessment programmes. Data is available through the Marine Online Assessment Tool: https://moat.cefas.co.uk/. This data is used to help us monitor the levels and trends of plastic pollution and inform our decisions on how to tackle marine litter.

We also published the Litter Strategy for England in April 2017, setting out our aim to deliver a substantial reduction in litter and littering within a generation. The Litter Strategy brings together communities, businesses, charities and schools to bring about real change by focusing on three key themes: education and awareness; improving enforcement; and better cleaning and access to bins. A copy of the Litter Strategy can be found at: www.gov.uk/government/publications/litter-strategy-for-england.

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.

The measures taken in EU Directive 2019/904 Article 5 place restrictions on items which can be placed on the market within the EU. Any item listed in Article 5 which is produced in the UK will therefore not be able to be sold in the EU from July 2021.

Waste is a devolved matter. Having left the EU, the UK Government now has the opportunity to reprioritise and refresh our environmental policy. We will be focusing on tackling single-use plastic items in ways that work best for us, including considering alternative approaches to the Directive to deliver the same or better overall outcome.

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.
