Endev – Turning waste into resources
PAKU-process
The Background
Municipal sludge consists of all the organic and inorganic compounds extracted from the wastewater during the wastewater treatment process. Wastewater treatment plants are becoming increasingly efficient in eliminating these compounds from the wastewater which leads to more ending up in the sludge. Thus, the sludge contains many unwanted components that are harmful to the environment. The following unwanted components are usually found in municipal sludge:
-
Bacteria and viruses
-
Pathogens
-
Drug residuals
-
Micro plastics
-
Heavy metals

Upcoming projects
Napapiirin Energia ja Vesi (NEVE) in Rovaniemi
-
The NEVE project is the first commercial PAKU facility delivery. The startup will be in the beginning of 2019. The project is granted the status of a key project in nutrient recovery by the Finnish Ministry of the Environment. A full scale PAKU facility is being built to handle the sludge from the Rovaniemi city wastewater treatment plant. The aim is to utilize the nutrients of the sludge in making cheap and safe recycled fertilizers and producing district heat.
