Climate Neutral Group | (Co-)fermentation is a natural degradation process in which biogas is released under controlled conditions. The biogas produced is converted in a combined heat and power installation (CHP) into sustainable electricity, which is then supplied via a green power supplier to many thousands of households in the Netherlands.

The biogas project involves several pig farms, which, by installing biogas installations, no longer have to dispose of all their manure on local fields in order to meet their area’s governmentally mandated nitrogen absorption limits.
The project concerns the financing of greenhouse gas reductions by biogas plants at various locations in the Netherlands and involves over 540 hectares of arable land and five pig farms. It enables companies to operate sustainably and to demonstrate that both circularity and compliance with strict regulations are possible. The fermentation of manure and other residual flows produces electricity that is fed into the national power network.
The fermentation installations use a mixture of manure from pig farming, arable crops and residual organic products from the food industry. The project will reduce methane emissions into the atmosphere and replace fossil fuels used to heat local buildings. In addition, the generated electricity is fed to the grid via ‘gas to electricity’. This installation complies with the relevant regulations and is recognised under Category 3 of the Netherlands Food and Consumer Product Safety Authority. This recognition makes it possible to process animal protein-containing products (such as unwrapped food and dairy) into biogas and plant food. The digestate (the residual product after fermentation) from the biogas plant is processed and sold as plant food to replace artificial fertilisers.
