A cluster of environmental companies has sprung up around Kujala Waste Treatment Centre. The biological and grease trap waste received by Päijät-Häme Waste Disposal company (PHJ) is treated at the composting facility, for reuse as compost in preparing seed beds. Gas generated by the biowaste digestion process is reprocessed into transport fuel. PHJ forwards scrap metal to the recycling service companies Kuusakoski and Stena Recycling. Rudus manufactures crushed concrete products from concrete waste, for use by the earthworks sector. Tarpaper Recycling Finland has a reception point and treatment process for used roofing felt. Roofing felt waste is used for manufacturing Bitumenmix, which in turn is used in asphalt production. PHJ is planning to expand its operations in 2014, to include the treatment of gypsum plasterboard waste in its plasterboard production process.
