Laboratory-scale conversion of agricultural waste into bioplastics
Sector
A1.6Support activities to agriculture and post-harvest crop activities
Needs/ Problem statement
to improve the management of natural resources used in agriculture, such as water, soil and air
Objective
The project stems from challenges linked to the difficulty of managing waste products from the agricultural brewing sector and the livestock industry, specifically the problem of waste in the form of spent grain and silage maize contaminated with aflatoxins under certain environmental conditions. Bioplastics, derived from renewable sources, offer a promising alternative to tackle the dual challenge of reducing the use of fossil-based plastics and the need to recover agricultural waste that would otherwise be destined for costly disposal.

Outcomes and final product
Laboratory-scale conversion of agricultural waste into bioplastics: microbiota, biotechnology and biochemistry in the service of PHAs. Qualitative and quantitative characterisation of brewers’ grains and contaminated maize silage. Development of an effective, low-cost and sustainable method for the preservation and treatment of waste materials for their conversion into PHAs. Selection of microbial strains and development of a laboratory-scale production process. Characterisation of powdered biomass and identification of potential polymeric matrices. Compounding tests and characterisation of the resulting blends.
