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.

Tickets can be purchased when registering to the World Water Week.
Cost: 450 SEK
Transportation and refreshments included.


For everyone’s safety, this year, no large bags will be allowed into the venue or at any social events. We encourage all participants to drop luggage at hotels before arriving to the venue. Please be prepared for bag search at the entrance.

14:00     Introduction:

              On  the pathway to SDG 6; FROM WASTE DISPOSAL TO 
              RESOURCE RECOVERY     
              Kim Andersson, Senior Project Manager, Head of  SEIs
              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.

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.
