Abstract
Despite of all the work done by UPM-Kymmene Oyj for minimizing the
amount of waste and for material recovery, there is still a considerable
amount of process waste available that is suitable only for energy recovery.
The objective of this project was to stop dumping of energy-recoverable
industrial process waste from all production units of UPM-Kymmene Oyj in the
Valkeakoski region, to ensure the quality of recovered fuel made of process
waste and to find the right techniques for feeding this fuel into a boiler.
Participants of the project were UPM-Kymmene Oyj and VTT Energy.The main
stages of the project were: 1) fractination of process waste according to
production units, 2) sampling and analysis, 3) plant for energy recovery, 4)
instructions for the operation of the crushing plant, 5) analysis of the
recovered fuel made at the crushing plant, 6) planning and testing of fuel
storage, 7) technical development of fuel feeding, and 8) measuring of
emissions, including fuel and ash analyses.The project started in summer 1998
and it terminated in 2000.Sampling and analysis proved that process waste from
the production units is, excluding few exceptions, suitable for energy
recovery.Due to varying properties of different waste materials they must be
properly mixed to achieve a homogenous quality of recovered fuel and the
feeding of the fuel must be done properly.
