Harderwijk, The Netherlands
The plant is equipped with a Bright Biomethane biogas upgrading system. The bioenergy plant is called ‘Bio-energiecentrale Harderwijk’ and produces annually approximately 12.4 million Nm³ biogas annually from 65,000 tonnes of manure and 35,000 tonnes of agricultural waste products. The biogas is upgraded to 8 million Nm³ biomethane which is distributed through the gas grid, and is equivalent – and the renewable alternative – to the gas consumption of 6,000 households.
Digestate treatment technology
The project includes a digestate treatment technology resulting in three end products: biomethane, clean dischargeable water and digestate or compost. High-quality fertilisers are processed for local sales in the agriculture sector and are used as raw material. After hygienisation, the digestate is separated into a thick and a thin fraction by a filter press. This exportworthy thick fraction is exported. The thin fraction passes through a biological purification, which results in dischargeable water that is discharged into the sewer.
