17 Conclusions The new Waste to Energy plant in Nybro implements a new CHP concept based on proven technology with newly developed improvements. It serves as a reliable concept for production of heat and electricity from waste meeting stringent emission requirements, is fuel flexible and has low LCC costs. Modularisation, low investment costs per MWth and a EPC delivery approach results in fast realisaiton times and the possibility of local thermal waste utilisaiton. The concept fits perfectly as a decentralized waste to energy solution fitting to smaller- or medium-sized communities utilizing the locally available combustible waste June, 2015 Valmet Author / Title
