On the Friday at the World Water Week, SIANI together with SEI, SIWI and SLU, are organising a thought-provoking field visit to SLU to look at a fly larvae composting system.

This visit will look into possible solutions to the world’s growing waste problems. To close the loop and take advantage of the nutrients in the waste, we look at a fly larvae-composting system where waste is converted into proteins. We also visit a pilot plant for testing different techniques for anaerobic digestion.


From 2 September 2016 at 11:00 to 2 September 2016 at 16:00

13:00     Bus leaves to Swedish University of Agriculture Sciences

14:00     Introduction:

On  the pathway to SDG 6; FROM WASTE DISPOSAL TO
RESOURCE RECOVERY. Kim Andersson, Senior Project Manager, Head of  SEI’s Initiative for Sustainable Sanitation

14:00     Visit the first treatment plant
The first treatment plant is a protein recovery plant where fly larvae is used for processing latrine waste as well as solid waste where up to 40% of the incoming material is converted into fly larvae, then to be used as high quality animal feed. Ass . Prof Björn Vinnerås , Swedish University of Agriculture Sciences

15:15     Coffee and walk to digestion plant at Swedish Institute of Agricultural and Environmental Engineering

15:45     Visit the second treatment plant
The second pilot treatment plant is a mobile anaerobic
digester, situated in a shipping container. This unique
treatment unit enables advanced testing of a large variety of substrates and process alternatives in a very scalable size. Ass. Prof Björn Vinnerås, Swedish University of Agriculture Sciences

17:00    Bus goes back to Stockholm
