Circular economy in the Peruvian region of La Libertad

Researchers develop a biodegradable packaging made with agro-industrial waste

Specialists from CITEagroindustrial Chavimochic and the National University of Trujillo, in the region of La Libertad, developed a raw material from agroindustrial waste that can replace the use of plastics for the manufacture of food packaging.

The project seeks to develop these biodegradable materials from non-food sources to avoid and reduce the use of synthetic polymers (plastics), thus contributing to the improvement of productivity and competitiveness in the north of the country.

The researchers used different residues, such as asparagus peel, avocado seed, mango pepper and peel, and grape marc, among other residues that are obtained from the agro-industrial companies that operate in the La Libertad region to create the raw material for the packaging. These residues are used to prepare the raw material to produce the packaging that will cover and protect food, which will be used again by these companies and generate a circular economy process.

Agro-industrial waste goes through a biotechnological process in the laboratories of the CITE and the UNT to obtain biopolymers: bacterial cellulose, polyhydroxyalkanoates, and starch. These compounds are an attractive alternative to common plastics, as they are of biological, renewable, and biodegradable origin.

This new development also allows the companies in the sector to be more competitive and their products can reach more national and international markets in perfect conditions, thus achieving the economic reactivation of the sector, according to the Technological Institute of Production (ITP) of the Ministry of Production.
