The first commercial delivery of a full-scale sludge combustion plant based on the novel technology was accomplished in a pilot project in 2019. The plant was built to handle the sludge produced in the wastewater treatment plant of Rovaniemi city (Finland). The primary target is to recover and recycle the nutrients of the sludge for fertilizer purposes while producing district heat. The project was granted the status of a key project in nutrient recovery by the Finnish Ministry of the Environment.
