NewsSea fungus breaks down ocean plastic that has basked in sun’s UV rays
A fungus living in the sea can break down the plastic polyethylene, provided it has first been exposed to UV radiation from sunlight. Researchers from, among others, Royal Netherlands Institute for Sea Research (NIOZ) published their results in the scientific journal Science of the Total Environment. They expect that many ...

NewsBiobased building materials less sustainable than concrete in South Africa, experts find
Scientists at the University of Bristol have discovered that mycelium composites, biobased materials made from fungi and agricultural residues, can have a greater environmental impact than conventional fossil-fuel-based materials due to the high amount of electricity involved in their production. Source: Karana et al. Mycelium based composite in ...
