Waste and biomass management involves the proper handling, treatment, and utilization of organic and inorganic materials to minimize environmental pollution and promote sustainability. Wastes, including household, industrial, and agricultural residues, if not managed properly, can lead to soil, water, and air pollution, as well as health hazards. Biomass, which consists of organic materials such as plant residues, animal manure, and food waste, can be converted into useful products like bioenergy, compost, and biogas through recycling and energy recovery processes. Effective management of wastes and biomass not only reduces environmental impacts but also contributes to renewable energy production, resource conservation, and a cleaner, healthier environment.
