Economic value of straw carbonization
2024-08-27
As an advanced treatment technology, straw carbonization can not only effectively solve the environmental problems caused by straw accumulation, but also convert it into high value-added biomass energy and carbon-based fertilizer, bringing significant economic value. The following are the main economic values brought by straw carbonization:
1. Biomass energy production
• Combustible gas: Combustible gas, mainly hydrogen, methane, and propane, produced during the straw carbonization process. After decoking and purification, it can replace natural gas, liquefied petroleum gas, etc., and be used for civil or industrial production. This kind of bioenergy has the characteristics of inexhaustible use and clean combustion products, which has positive significance for protecting the atmospheric environment and reducing carbon emissions.
• Charcoal: Charcoal made from carbonized straw is an environmentally friendly biomass energy that can be used in many fields such as heating, barbecue, and power generation. It has high calorific value, low ash content, and no harmful gases are emitted during the combustion process. It is an ideal choice to replace coal, oil, and natural gas.
2. Chemical raw materials and agricultural inputs
• Wood vinegar: Wood vinegar produced during the carbonization of straw has wide application value. In agriculture, it can be used as soil conditioner, deodorant and fungicide, feed additive, etc.; in industry, it can be used as beverage additive, food preservative, etc. After the wood vinegar is distilled and prepared, it can be made into finished products for use, further increasing its economic value.
• Wood tar: Wood tar is an organic compound containing high levels of hydrocarbons, acids, and phenols. After processing, creosote, antipolymers, flotation foaming agents and other products can be obtained. It is widely used in medicine, Sectors such as synthetic rubber and metallurgy.
3. Soil improvement and agricultural efficiency improvement
• Carbon-based fertilizer: Biochar, the product of carbonized straw, has the characteristics of loose texture, rich pore structure, and large specific surface area. It can significantly improve the water and gas conditions of the soil and increase soil fertility. The application of carbon-based agricultural inputs such as biochar-based fertilizers and biochar-based organic fertilizers can promote crop growth and improve crop yield and quality. At the same time, biochar also has good adsorption capacity and can be used to adsorb and fix pollutants in water, gas or soil, playing a positive role in improving the agricultural ecological environment.
4. Industrial chain and employment promotion
• The development of the straw carbonization industry can drive the formation and development of related industrial chains, including straw collection and storage, carbonization processing, product sales and other links. This will provide more employment opportunities in rural areas, promote farmers' income increase and rural economic development.
To sum up, straw carbonization brings significant economic value in biomass energy production, chemical raw materials and agricultural input production, soil improvement and agricultural efficiency enhancement, as well as industrial chain and employment promotion. With the continuous advancement of technology and the promotion of application, the economic value of straw carbonization will be further explored and enhanced.
