1. Fuel: Biomass pellets can be used as fuel to replace traditional fossil fuels, such as coal, oil and natural gas. Biomass pellets produce relatively low carbon dioxide emissions when burned, so it is a more environmentally friendly energy source.

2. Industrial use: Biomass pellets can be used for industrial heating, such as industrial ovens, industrial boilers, etc. In addition, biomass pellets can also be used as fuel in thermal power plants to provide energy for electricity production.

3. Agricultural use: Biomass particles can be used as organic fertilizer to provide nutrients for crops. In addition, biomass pellets can also be used as animal feed, such as feed for poultry, pigs and cattle.

4. Environmental remediation: Biomass particles can be used for environmental remediation, such as soil improvement, vegetation restoration, etc. By increasing soil organic matter, improving soil structure, increasing soil fertility, promoting vegetation growth, thereby improving the ecological environment.

5. Other uses: Biomass particles can also be used to make handicrafts, furniture, etc.

In short, biomass pellets have a wide range of uses and can be used as a multi-functional renewable energy and resource, which is of great significance in promoting sustainable development and environmental protection.
