The largest and northern most full-scale system for wastewater irrigation of Salix plantations in Sweden.
The local community in Hedemora has long experience in producing biofuel from Salix plantations. The cooperation between Hedemora Energi AB and local farmers has resulted in irrigation of 75 acres of Salix Plantations. The local farmers in the project are guaranteed to sell their biofuel to the local municipal heating plant. As a result the project is contributing to the local production and consumption.

To stop eutrophication of the sea, Gryaab treats the Gothenburg region waste water. The residue, sewage sludge, is turned into soil, fertilizer and a climate-friendly vehicle fuel. Each year, approximately 55,000 tonnes of sludge are produced at Gryaab. The treated sludge contains nutrients and mulch – what is needed for crops to grow. Some of the decayed sludge is composted and used as construction soil. About half of the sludge is hygienised and used as fertiliser, replacing artificial fertiliser.
