Using biological resources and waste in closed loops to reduce environmental footprints.
Examples: converting food waste to biogas, bioplastics (PHA) from microbes, biorefineries and nutrient recovery. Principles: waste as resource, renewable inputs, cascading use.
Biomass should be used in cascades: food first, then materials, then energy. Biorefineries convert residues into chemicals. Land use limits must be respected.
Example: mycelium materials replace packaging foam.
