3. 2. Integrating novel circular economy technologies in complex trans-sector value chains : Case study of insect larvae conversion technology within waste and feed value chains

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Audinisa Fadhila; [2020]
   Keywords : Organic waste; circular economy; circular value chain; sustainable transition; transition studies; Black Soldier Fly; sustainable animal feed;

   Abstract : Even as the current linear value chains (LVC) of organic waste and animal feed hold the potential to become circular, these practices continue to pose major environmental risks such as deforestation and overfishing.
