The document discusses biomass briquette plants, which produce solid fuel briquettes from organic waste through a high-pressure process without chemicals. The briquettes can be used as fuel for electricity generation, heating, and cooking. Setting up a biomass briquette plant provides a low-cost way to produce renewable energy from waste while reducing pollution. It can help protect the environment from greenhouse gases compared to using traditional or coal fuels. The plant requires less maintenance than coal and can be a profitable business internationally.
