Waterproblems find their solutions
Fossil fuel dependency
There is a strong dependency on fossil fuels.
When water authorities maintain roadsides of waterways, a lot of grass clippings are produced. The clippings are often seen as a waste product while it can be used as biomass, the raw material for sustainable bio-energy.
The WWTP in Harderwijk has a bio-energy plant, where biomass is converted into bio-gas. In addition to manure, sewage sludge and (pruning) wood waste, the biomass consists of grass clippings collected by the water authority during maintenance of waterways. The plant can produce 12.5 million cubic meters of biogas per year, for 5000 households to benefit from.
