The company developed and launched a technology for treating communal sewage sludge that is economical in case of small scale production too. This technology is a self-supporting technology for drying and pelleting sewage sludge without external need of fossil fuel or any other additional material. Consequently, the most reasonable utilization of pellets is not retail utilization, but meeting the heating and hot water needs of properties owned or operated by municipalities that operate waste water treatment plants. The pellets generated have a heating value equivalent of the brown coal heating value. It uses a negligible external energy input by reusing 30-50% of the generated pellets in the process to run the drying unit. The technology fits into the ‘energy from waste’ policy of the European Union. It enables wastewater plants to meet the strict EU environmental regulations and at the same time, reduce their sewage sludge treatment costs with 50-75%.
