Solid Fuel Recovery (SFR) is the process of converting solid waste into Solid Recovered Fuel (SRF). SRF is a high-quality fuel source that is produced by shredding and dehydrating solid waste, such as biodegradable waste, food and kitchen waste, green waste, paper, and other combustible components of Municipal Solid Waste (MSW). SRF has a high calorific value and can be used as a substitute for fossil fuels in various industrial processes, including cement production and energy generation. The production of SRF is an important step towards reducing the amount of waste that is sent to landfills, as well as decreasing the reliance on non-renewable energy sources. The SFR glossary is a useful resource for understanding the terminology used in this field.
