Prefeasibility study of a regional sludge incineration plant

The Finnish Government approved in April 2008 the new national waste plan to the year 2016. The plan describes how waste management in Finland should look like in 2016 and how the goal will be achieved. The plan also contains a separate action plan for preventing the generation of waste. The biowaste strategy particularly aims to reduce the amounts of biodegradable municipal waste ending up in landfill sites over the period 2006-2016. In 2006 the amounts of biodegradable wastes being disposed of in landfills should correspond to less than 75% of the 1994 level, while by 2016 the quantity should only amount to less than 35% of the figure for the benchmark year. This means that only a maximum of 25% of all the biodegradable waste expected to be generated in 2016 can go to landfill.

With regard to WWTP sludges, the measures taken to help reach this target will include more recycling, the wider use of biological waste treatment methods such as composting, and the increased use of sludges in energy production.

In the study area, the generation of WWTP sludge is approximately 506 000 metric tons annually. In addition, approximately 526 000 metric tons of sludges is collected from rural areas annually.
