Harnessing Biomass: From Organic Waste to Renewable Energy Solutions

Biomass is a renewable resource that includes organic materials and waste, providing a sustainable source of energy and materials. It is the largest supply of carbon on Earth and can replace petroleum-based products. Biomass is converted into energy through processes like photosynthesis and can be used to produce fuels such as gasoline and diesel. Waste biomass, including animal manure, can generate electricity through digestion and methane production. Biogas from landfills is another energy source. Biomass also offers solutions for plastic waste by creating recyclable and biodegradable products.
