Straw are widely used in paper making, ethanol production or used as feed for animals in the past. In recent years, the new way of processing these straws has caught people’s attention that is pelletizing. With the development of biomass pellet production, more and more straw are available as raw materials for biomass pellet making.

 

As researched, a large amount of straw is generated and left as much in paddy fields, which causes greenhouse gas emission as methane, however, making straw pellets can solve the problem. Besides, the ever-growing energy consumption, remaining high prices for converting energy products and ecological requirement enforcement to electric power plants determine the interest to the use of a biomass as fuel for the future generation energy supply.

 

Straws are characterized with high calorific value, low moisture content. And after pelletizing, the calorific value of straw pellets are about 18-19MJ/kg, the ash content is lower than 3% and the moisture content are lower than 10%, which are better to burn. In addition, the burning of straw pellets causes zero CO2 emission, and straw pellets are carbon-neutral. Burning the straw pellets to generate energy simply returns the carbon dioxide to the atmosphere, which will then be reused by the next biomass growth. Therefore it is economical and environmental to utilize straw like rice straw, wheat straw or corn straw for pellet production.



Straw pelleting processing:

1. Crushing
2. Drying
3. Pelletizing
4.Cooling
5. Packing

Dongding can provide the whole straw pelleting plant with the best quality.
