On 8 April 2021, we published our response to the call for evidence on the need for standards for bio-based, biodegradable and compostable plastics: www.gov.uk/government/consultations/standards-for-biodegradable-compostable-and-bio-based-plastics-call-for-evidence.

While neither a specific assessment of oxo-biodegradable plastic sheeting used by farmers, nor an assessment comparing bio-based resin from starch and lactic acid in biodegradable products used in agriculture to oxo-biodegradable plastics has been made, the aforementioned call for evidence covered oxo-biodegradable plastics.

The Government response acknowledges that there is currently insufficient evidence demonstrating that oxo-biodegradable plastics perform as claimed and biodegrade, without residue, in a reasonable timeframe in the open environment. We continue to monitor the latest developments and evidence and are keen to see research published in international peer reviewed journals illustrating how these plastics degrade in the marine environment, open environment, and under the soil, specifically under naturalistic conditions, as opposed to experimental models of aging. We also welcome further research on the full environmental impacts of using bio-based plastics.

Over the coming months, we intend to commission a research project to further consider the evidence that has been supplied to the call for evidence within the context of wider literature and new research.

We do not plan to make representations to the European Commission on the usability and safety of oxo-biodegradable products in the farming industry.
