Sustainability & Environment

In May 2018, the EU proposed a single-use plastics ban intended to protect the environment, save consumers money, and reduce greenhouse gas emissions. As part of the new laws, the EU aims for all plastic bottles to be recycled by 2025, and non-recyclable single-use items such as straws, cutlery, and cotton buds to be banned.

An ambitious step – and arguably necessary – but there is no denying that plastics are extremely useful, versatile and important materials, playing a role in countless applications.

The challenge to science, industry and society is to keep developing, producing and using materials with the essential properties offered by the ubiquitous oil-based plastics of today – but improving the feedstocks and end-of-life solutions, and ensuring that consumers use and dispose of products responsibly.

A number of innovative solutions have been proposed to help plastics move towards a more sustainable future.

‘Chemists have 100 years’ experience with using petrochemicals as a raw material, so we need to start again using renewable feedstocks like sugars as a base for synthetic but sustainable materials,’ said Dr Antoine Buchard, a Whorrod Research Fellow at the University of Bath, UK.

Dr Buchard leads a group at the Centre for Sustainable Technologies at the University of Bath that are searching for a sustainable solution for single-use plastics. Using nature as their inspiration, the team have developed a plastic derived from thymidine – the sugar found in DNA – and CO2.
