Biopolymers

WRAP has undertaken research to clarify consumer understanding of biopolymers and also issued a ‘statement’ to communicate its viewpoint.

WRAP's consumer research has shown that the emerging trend for retailers to use biopolymer packaging materials needs to be introduced with care and clearly communicated if potential environmental benefits are to be gained.

The research has found that most consumers are confused about the wide range of new materials emerging with ‘biodegradable’, ‘home compostable’, ‘compostable’  and ‘degradable’ all being introduced in the UK as bags, pots, trays, films or bottle formats, albeit in relatively small quantities at present.

According to the research, consumers initially rate biodegradable and compostable plastics very favourably as they believe they just ‘break down’ after disposal. However when made aware of some of the possible impacts some of the biopolymers can have on plastics recycling, commercial composting or if sent to landfill sites, the respondents were less clear of the overall benefits, and were left feeling confused. Apart from some home compostable materials, there is currently no appropriate infrastructure for the materials to be collected and treated in the UK.

Prompted by the consumer research, the WRAP ‘statement’ on biopolymers helps to set out some of the considerations brands and retailers should review when considering the use of such packaging materials. This clarifies some of the definitions used, and factors to consider regarding disposal, consumer communication and environmental impact.

Clear labelling and guidelines for products is vital along with a better understanding of the full environmental benefits of the new materials. WRAP and other stakeholders are working with the Composting Association to modify standard tests and provide a certification service for home compostable packaging, and provide guidance on 'compostable' claims that such items carry.  WRAP is also planning several areas of work with key groups in the sector to review the options and impacts for collecting biopolymers via the plastic recyclables and food waste collection routes.
