Double carbon targets drive new outlets for the 100 billion-level straw industry (biomass pellet machinery)

Driven by the national strategy of “striving to reach the peak of carbon dioxide emissions by 2030 and striving to achieve carbon neutrality by 2060”, green and low-carbon has become the development goal of all walks of life. The dual-carbon goal drives new outlets for the 100 billion-level straw industry (straw crushing and returning to the field machinery, biomass pellet machinery).

Crop straw that was once regarded as agricultural waste, through the blessing of agricultural technology, what kind of magical effect has occurred in the transformation process of farmland from carbon source to carbon sink. “Twelve changes”.


“Dual carbon” goal drives the comprehensive utilization of straw in the 100 billion-level market

Under the “dual carbon” goal, the development of comprehensive utilization of straw can be said to be flourishing. According to the forecast of the Prospective Industry Research Institute, with the continuous improvement of the utilization rate of straw waste treatment in my country and the continuous advancement of technology, the market size of the straw waste treatment industry will maintain a steady growth trend in the future. It is expected that by 2026, the entire industry will grow The market size will reach 347.5 billion yuan.


In recent years, Qingdao City has adhered to the concept of “three completes” of global rectification, full utilization, and full conversion. It has continuously explored comprehensive utilization technologies of crop straws such as fertilizer, feed, fuel, base material, and raw material, and gradually formed a form that can be replicated. Industry model, broaden the way of using straw to develop rich peasant industry.


The new model of “planting and breeding cycle” broadens the way for farmers to increase income

Qingdao Holstein Dairy Cattle Breeding Co., Ltd., which has the largest breeding scale in Laixi City, as a ranch supporting facility, the company has transferred about 1,000 acres of experimental fields to grow wheat, corn and other crops. These crop stalks are one of the important feed sources for dairy cows.

The stalks are bundled off the field and converted into dairy cow feed through fermentation process. The excrement of silage produced by dairy cows will enter the green agricultural circulation system. After solid-liquid separation, the liquid enters the oxidation pond to be fermented and decomposed, and the solid accumulation is fermented. After entering the organic fertilizer processing plant, it will eventually be used as organic fertilizer for irrigation in the planting area. Such a cyclical cycle not only protects the environment, but also reduces production costs, and realizes the green and sustainable development of agriculture.

Zhao Lixin, director of the Institute of Agricultural Environment and Sustainable Development of the Chinese Academy of Agricultural Sciences, said that one of the ways to achieve carbon peak and carbon neutrality in my country’s agricultural and rural areas is to improve soil quality and increase the ability of farmland and grassland to sequester carbon and increase sinks. Including conservation tillage, returning straw to the field, application of organic fertilizer, artificial grass planting, and forage-livestock balance, improving the organic matter of farmland and grassland can increase the ability of greenhouse gas absorption and carbon dioxide fixation, and transfer farmland from carbon source to carbon sink. According to expert estimates, according to current international measurement requirements, excluding carbon dioxide absorption by plants, the carbon sequestration of farmland and grassland soil in my country is 1.2 and 49 million tons of carbon dioxide, respectively.


Li Tuanwen, head of Qingdao Jiaozhou Yufeng Agricultural Materials Co., Ltd., said that relying on the demand for silage in Qingdao’s local aquaculture industry, in addition to the original agricultural materials business, in 2019 they began to transform and try to expand green agricultural projects by providing social services. Involved in the field of crop straw processing and processing and utilization, “taking silage as an example, a cow needs more than 10 tons a year, and a medium-sized cattle farm has to import one to two thousand tons at a time.” Li Tuanwen said, the current annual increase in straw silage About 30%, all of them are used by local cattle farms. Last year, the sales revenue of this business alone reached about 3 million yuan, and the prospects are still good.

Therefore, they have launched a new fertilizer project for comprehensive utilization of straw this year, hoping to continuously adjust the composition of their main business, aiming at the direction of green and low-carbon agriculture, and integrating into the agricultural high-quality industrial system.


The biomass pellet machine accelerates the comprehensive utilization of straw resources, realizes the commercialization and resource utilization of straw, and is of great significance for saving energy, reducing pollution, increasing farmers’ income, and accelerating the construction of a resource-saving and environment-friendly society.
