Briquettes are compressed blocks of combustible material, typically made from biomass waste such as sawdust, wood chips, or agricultural waste. They are commonly used as an alternative to traditional fossil fuels like coal, oil, and gas, for heating and cooking. Here are some common uses for briquettes:

1. Household heating and cooking: Briquettes are a popular alternative to firewood for heating and cooking in households, particularly in developing countries where access to traditional fuels can be limited.

2. Industrial heating: Briquettes can be used in industrial boilers and furnaces as a substitute for coal or other fossil fuels. They can also be used in thermal power plants to generate electricity.

3. BBQ grilling: Briquettes are a popular fuel for outdoor grilling, as they burn longer and hotter than traditional charcoal.

4. Animal bedding: Briquettes can be used as animal bedding for livestock and other animals. They are absorbent and provide good insulation, helping to keep animals warm and dry.

5. Soil amendment: Briquettes made from organic materials can be used as a soil amendment to improve soil fertility and structure.

Overall, briquettes offer a sustainable and environmentally-friendly alternative to traditional fossil fuels, and can be used in a variety of applications for both domestic and industrial purposes.
