Food waste biogas


It is hard to estimate the amount of fermentable waste produced by industries (agribusiness, farming, food services…), but it is clearly a potentially important source of biogas.

The Objectives

Anaerobic digestion allows organic waste to be transformed into soil fertilizers and biogas for fuel, with minimal energy use.
Since January 1st, 2012, all “large producers” of fermentable waste (farming, agribusiness, medium and large retail, mass catering) are to process their waste in order to ease their subsequent return to Earth as fertilizers. 

The Process

Anaerobic digestion is a process by which organic material is broken down by micro organism in the absence of oxygen.
Fermentable waste is transported in a deconditioning unit that separates packaging from organic waste. The latter is sent to a biogas production factory.
Organic waste breaks down, producing fertilizers and biogas, which is used to generate heat or electricity.

Our Contribution

To comply with new regulations on fermentable waste, Paprec has partnered with Saria Industries to create Sariec, a company specialising in recovering fermentable waste.
Our first biogas factories have been set up in Bennet (85), Issé (44), and Etampes (91).
