Co-products for methanization: securing your organic inputs
Fertiappro supplies organic by-products for methanization, by leveraging its strategic position in Frasnes-lez-Anvaing between Belgium, Flanders, the Netherlands and France. Objective: secure your methane inputs and valorize organic matter from agriculture and agro-industry.
Why use by-products in anaerobic digestion?
Visit methanization is a process of degradation of organic matter in the absence of oxygen (anaerobic fermentation) by bacteria, producing biogas (rich in methane) and a digestate which can be used as an organic fertilizer or soil improver.
This process enables :
- From recycle organic residues (livestock effluents, crop residues, agri-food co-products, etc.) that would otherwise be little or poorly valorized; ;
- Produce a renewable energy, in the form of biogas; ;
- Generate a digestate can contribute to soil fertilization, partially replacing mineral fertilizers.
In many guides, agricultural methanization is presented as a lever for’circular economy, This is the ideal way to enhance the value of organic by-products and reduce waste.
What types of co-products are suitable for anaerobic digestion?
Technical documents and industry guides distinguish between several large families of methanizable substrates :
- Livestock effluents (manure, slurry) ;
- Gray starch
- Flax dust
- Cocoa shells
- Potato co-products
These materials are referred to as inputs or substrates in anaerobic digestion. They must be chosen and combined with care, as the composition of each co-product influences digester operation and process stability.
