The development of bio-based active plastic packaging for the food industry from cellulose obtained from plant biomass waste. Andaltec initiated the process of developing a method for extracting cellulose from a variety of agricultural waste materials found in Andalusia, including olive pruning, sunflower stalks, and wood from cotton plantations. Once the process of extracting cellulose from the different waste materials had been optimised, the methods for synthesising cellulose acetate and nanocellulose, which are the main components in the final products, were refined.
The extracted cellulose was employed for two distinct purposes: to obtain a thermoplastic biopolymer and to transform it into an additive that enhances the characteristics of the final material. The subsequent phase of the project was to develop a biodegradable and compostable polymer-based material for use as a raw material in the manufacture of food packaging. Andaltec has produced a prototype that meets the exacting standards of food regulations and offers effective barrier properties, extending the shelf life of foodstuffs. The material is sustainable due to its vegetable origin and biodegradable and compostable nature.
The project is financed through a line of aid for the implementation of R&D&I projects for private agents of the Andalusian Knowledge System, which is managed by the Andalusian Regional Ministry of Economy, Knowledge, Business and University of the Andalusian Regional Government.
