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

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. Therefore, a novel circular value chain (CVC) is proposed, connecting the organic waste stream with animal feed production by the use of insect-based organic waste conversion technology. The Black Soldier Fly (BSF) is chosen as the insect-based conversion technology since it has nutritional properties, which serves both waste treatment and animal feed material production purposes. Although there are already initiatives and collaborations in the Swedish context, the transition has not yet been successful. The study aims to identify and propose required solutions for the value chain transition. By using the transitional study tools of Technological Innovation System (TIS) and Multi Level Perspective (MLP) alongside sustainable value chain transition studies, it is found that technological and information-related adjustments are required to further enable the transition. Technological adjustments are studied from the perspective of Ragn-Sells AB as a potential insect- based organic waste conversion actor. Scenarios to see economical sustainability were designed based on the quantity fluctuation of waste as material input (3,000 tons per year and 15,000 tons per year), possibility of automated operation which affects both investment and operating costs of the facility, and procurement of small BSF larvae (off-site and in-site breeding). From the different scenarios designed, it is found that the scenario with the capacity of 15,000 tons per year, higher investment due to automation, and on-site breeding is the most preferable for the case. To answer information- related needs, an Informational Flow Framework (IFF) is proposed. The IFF consists of “Value Chain Stakeholders”, “CVC Relevant Regulations”, “Information Data Pool”, and “Information Flow”. The framework’s main function is to identify the type of material information required to be distributed in the system and the stakeholders whom require and/or provide various information, with the main goal of increasing the trust among the stakeholders related to material information.
