COLLAGEN AND ANTIOXIDANTS FROM SEA URCHINS: WASTE VALORIZATION CHALLENGES TOWARDS REGENERATIVE MEDICINE
… than 90-95% of their total mass) is discarded as waste. From the point of view of the circular economy, there is now a great interest in food waste, pointing to the valorization of biomasses to obtain products with added value. In fact, it's already been shown that sea urchin waste contains highly …

Why Landfills Endure: Quantifying economic barriers to material and energy recovery from municipal solid waste in the United States
Municipal solid waste (MSW) is a heterogeneous mixture of materials discarded by residential and nonresidential generators at end-of-life processing facilities for treatment and disposal. Conventional treatment methods reduce waste volumes through recycling via material recovery facilities, energy …
