The project 'Waste to worth' research project started in 2013 and goes on throughout 2016.
The project aim is to convert manure (animal and human) and organic waste into protein rich animal feed. Today in Uganda only a small portion of the organic waste fractions are utilized and recycled back to agriculture as fertilizer. Most is just discarded, ending up as an environmental pollutant and a spreader of diseases. We will use fly larvae for degradation of the material and convert it into valuable animal feed.
The larvae degrade up to 80 percent of the organic matter, leading to that 10 kilos of waste are converted into one kilo of larvae mass that can replace fish meal as protein feed. Our main focus is the treatment technology – systems design for maximal protein production and reduction of disease transmission risks from the system.

Participating from the department: Björn Vinnerås and Cecilia Lalander.
The project is funded by VR/Uforsk.
External partner is Makerere University.
