Converting Municipal Solid Waste (MSW) into biogas is an eco-friendly solution that involves collecting and sorting organic waste, digesting it in the absence of oxygen to produce biogas (primarily methane), and using the biogas as a renewable energy source for electricity, heat, or transportation. This process reduces landfill waste, lowers methane emissions, and provides a sustainable energy alternative while recycling valuable nutrients from the residual digestate as a soil conditioner or fertilizer.
