“…Gasification converts organic waste into synthesis gas, which can be processed for heat, electricity, or biofuels [99,100]. Pyrolysis, on the other hand, heats waste materials without oxygen, producing biochar, bio-oil, and gases [101,102]. Biorefineries extract bioactive compounds from waste, supporting applications in pharmaceuticals, cosmetics, and functional foods, while waste oils and fatty acids are processed into biodiesel, further aligning industry practices with sustainability objectives [103][104][105][106][107].…”
