Aimplas produces plastic film from coffee waste

Aimplas, the Plastics Technology Centre, has produced a plastic film from used coffee grounds, transforming waste into a source of high-value products.

Converting biological waste into resources is one of the keys of the circular economy, and the main objective of the European WaysTUP! Project, financed by the Horizon H2020 programme, is working on different lines of research to establish new value chains for the use of urban biowaste.

According to Nuria López, the project’s principal investigator at Aimplas, WaysTUP! is a clear example of how biowaste can play an important role in the transition towards a circular economy by avoiding biowaste generation and harnessing its potential as a source of high-value secondary resources.

“In our case, we’re transforming coffee waste into plastic film for packaging. Meanwhile, other project partners, such as SAV – Agricultores de la Vega de Valencia, are project coordinating partners responsible for recovering waste to produce food additives, feed and oils for the food and cosmetic industries,” López said.

Various forms of urban biowaste, including fish and meat waste, and used coffee grounds and cooking oil, are being transformed into new biobased products, such as food additives, condiments, insect protein, bioethanol, biosolvents and bioplastics for packaging.

The biobased plastic film produced by Aimplas was obtained from PHA from restaurant coffee grounds collected by Bio-Bean (United Kingdom). Aimplas first formulated the PHA so it could be processed by extrusion and then manufactured the film, which can be used in different types of flexible packaging.

The WaysTUP! Project aims to improve the current perception of local communities about the importance of urban biowaste as a resource.

The idea is to promote the community’s active participation in selective urban biowaste collection for subsequent recovery. In addition, local administrations are receiving guidelines on adopting new organisational models in favour of urban biowaste recovery, as well as European-level evidence-based policy recommendations for decision-making.

The project is financed by the EU Research and Innovation programme Horizon 2020 under funding agreement no. 818308. A total of 26 research centres, local authorities, companies and city networks are participating in the project.
