Recently, the Indian bamboo biomass pellet production line project passed the environmental impact assessment approval stage and is about to start construction.

This project is invested by a small Indian bamboo and wood products company with an investment of US$150,000. The project covers an area of ​​880 square meters. The project will produce 12,000 tons of biomass pellets annually, of which 100 tons will be used as raw materials for the biomass burner of the client company’s bamboo product project, and the rest will be sold out.

This project is a new project. The main construction content of this biomass pellet plant project is the main project and auxiliary projects, mainly including processing areas, raw materials, finished product warehouses, office areas, etc. The main construction contents of this project include the main project (production workshop), auxiliary projects (raw materials, finished product warehouse, storage area, office area, etc.), public projects (power supply, water supply, drainage system, heating), and environmental protection projects (including waste gas, wastewater, noise, and solid waste disposal).

The main production equipment of this project includes bamboo pellet machine, box-type transformers, drum chippers, crushers, kilns, burners, bag dust collectors, etc. The raw and auxiliary materials used in this project include bamboo and wood scraps, biomass pellets, water, electricity, etc.

The production process of this biomass pellet production line project during the operation period includes: raw material collection and transportation → crushing → drying → screening → pellet forming → cooling and packaging. The waste gas generated during the operation of this project mainly includes process dust, drying dust, burner waste gas, and oil fume waste gas generated by chipping, crushing, screening, and granulation processes, etc.

The pollutants in the waste gas are mainly volatile organic compounds; this project does not generate production wastewater during the production process, and the main wastewater is domestic sewage, which is discharged into the sewage network after being treated in a septic tank, and then discharged into the sewage treatment plant through the sewage network, and then discharged into the local river after being treated to meet the standards.

Mechanical equipment noise is generated during the operation of the project; the noise sources during the operation period are mainly the noise generated by the operation of equipment such as chippers, crushers, burners, pellet forming machines, screening machines, and waste gas treatment facilities, as well as the transportation noise of forklifts and loaders, and the noise source strength is about 85~100dB(A).

The production equipment are all arranged inside the factory building. The noise source intensity can be reduced by about 15~20dB by taking measures such as base vibration reduction, sound insulation, reasonable layout, and using factory building sound insulation. The traffic noise generated by forklifts and loader transport vehicles is mainly intermittent noise, and measures such as strengthening management and controlling vehicle speed are planned to be taken.

After the project construction is completed, after taking measures such as base vibration reduction, sound insulation, and factory building sound insulation, the daytime noise values ​​at the east, south, and west factory boundaries of the project meet the requirements of the “Environmental Noise Emission Standards for Industrial Enterprises”.
