The Graskracht project was intended to promote the conversion of grass to energy in Flanders. This project was mainly focused on the use of grass from roadsides and nature reserves. Grass is often seen as an annoying waste product, but it is certainly possible to use it much more efficiently.

Verge and natural clippings are not produced on agricultural land. They are therefore not cultivated energy crops that compete with food production for the agricultural area. This makes the fermentation of natural and roadside cuttings socially and economically more acceptable.

The technical-biological feasibility of energetic valorisation of grass clippings by fermentation has been sufficiently proven, but there are still economic and logistical obstacles such as litter in verge cuttings, reduction and removal of the clippings. Concrete investments in suitable processing capacity are required. Different fermentation techniques have potential for the processing of clippings.
