Digestion converts organic substances into gas via micro-organisms. These organic substances can be found, for example, in co-products from the food and fermentation industries. 

The fermentation of co-products, in practice mainly liquid co-products, is a biological process in an oxygen-poor environment. The gas that is released during the fermentation process can be used for various purposes. For example, it can be converted into electricity, purified into natural gas, or heat (energy). To produce as much gas as possible, the composition of the raw materials is very important. At Looop, we have a large range of organic co-products that are suitable for processing in digesters. 


Looop has co-products for different types of fermentation and digesters. 

Manure digester
Co-fermentation digester
Industrial digester
Vegetable digester




When processing organic substances, such as organic co-products, into biogas, a new residual flow is created. 

This co-product is digestate, an excellent soil improver. 
Digestate products are sustainable, high-quality organic fertilizers that are very suitable for agriculture, horticulture, and cattle breeding. Want to know more?

Soil Improvers



Biogas can be produced by processing and purifying it. Green gas has the same properties as natural gas

It is therefore a suitable alternative for natural gas and plays an important role in the energy transition. Green gas can be connected to the natural gas network and used as a transport fuel, for example. This saves fossil raw materials and reduces CO2 emissions.  


At Looop, we repurpose co-products.

Sustainable energy is generated through the utilization of co-products.

In that way, we reduce our dependency on fossil fuels. However, our co-products find a new lease of life in various applications. Learn more about them here:

In addition to finding new valorization through renewables, our co-products also find new purposes in pet food, animal feed, and as substrates for insects.
