Background: To achieve climate neutrality, fundamentally new concepts of circularity need to be implemented by the building sector as it contributes to 40% of anthropogenic CO emission. Fungal biotechnology can make a significant contribution here and help eliminate fossil dependency for building material production. Recently, we have shown that the medicinal polypore Fomes fomentarius feeds well on renewable lignocellulosic biomass and produces composite materials that could potentially replace fossil fuel-based expanded polystyrene as insulation material.

Article Synopsis
  • Aquaculture solid waste (ASW) is nutrient-rich but can harm the environment if not managed well, prompting this study on using black soldier fly (BSF) larvae to convert it into biomass.
  • Five different chicken feed substrates were tested with varying ASW levels, revealing that a 75% ASW mixture led to optimal larval growth and nutrient assimilation, while higher ASW levels resulted in lower growth due to indigestible fibers.
  • Overall, BSF larvae can effectively manage ASW, providing a solution for waste reduction while producing nutritious insect biomass.
