After crops are harvested, a large amount of residual straw will be left behind. Burning straw will not only release a large amount of harmful gases, but also cause pollution to the atmospheric environment. To this end, Keqiao District, Shaoxing City, Zhejiang Province actively explores new ways to dispose of straw and turn "ecological burden" into "green wealth."
Recently, Huashe Street in Keqiao District launched a "Straw Recycling Operation" for the jurisdiction. Law enforcement officers from the Street Comprehensive Law Enforcement Squadron walked into the high-incidence area of burning in Dongzhou Community and recycled the straw to be burned there. "We have recycled straw in several areas with high incidence of incineration, including Xiaozhe Village, Zhanglouju, Huashe Village, Jiefangju, and Shadiwang Village, with a total recovery of 1.5 tons." The relevant person in charge of the Huashe Street Comprehensive Law Enforcement Squadron said.
How to deal with recycled straw? Law enforcement officers sent the recycled straw to Zhejiang Runsheng New Energy Co., Ltd., and used core equipment such as the independently developed "Biomass Flash Continuous Distillation Process" and "Diffusion Gathering Device for Biomass Raw Material Dryer" to convert the straw into Biomass Gas and biomass charcoal.
"We pass straw through the biomass gas and carbon co-production production line to turn it into treasure. The entire production process has negative energy consumption and negative carbon emissions. The biomass charcoal it converts into is also a carbon-negative material. It not only fixes carbon, but also improves soil and promotes agricultural production to 'lose weight and reduce medicine', with significant economic and ecological benefits." Relevant staff of Runsheng New Energy introduced that the project's "Biomass High-Temperature Pyrolysis Gas and Carbon Cogeneration Technology" has obtained 5 national invention patents, breaking through the intermittent operation of traditional technologies for continuous rapid high-temperature pyrolysis of biomass and low calorific value of gas. problem.
In addition to frequently carrying out "straw recycling operations", Huashe Street has also set up temporary village community stacking points and street straw storage and storage centers. At the same time, collection and storage transportation lines are set up to facilitate village community grid members to travel to the village and enter the fields, and guide farmers to collect and collect straw. At the same time, a process system of "production, harvesting, storage, transportation and use" for comprehensive utilization of straw has been established. Subsequently, through the location advantages of new energy, recycled straw will continue to "turn waste into treasure" and open up diversified and innovative utilization of straw. new model.
Lanting Street, also located in Keqiao District, in order to facilitate farmers, the street relies on village-level domestic waste transfer stations to establish straw storage and storage points in each administrative village. Farmers only need to send their own straw to the storage and storage points, and after sorting, weighing and recycling, you can receive a corresponding share of points, and the points can be spent as money. This is also a new coup explored by Keqiao District to effectively solve the problem of banning straw burning.
Pressing, adding organic materials, composting... Recently, staff of Xulanyuan Agricultural Biotechnology Co., Ltd. located in Lanting Street were busy roughing the freshly collected straw. "By repeating multi-layered stacking and turning the piles regularly, after a period of time, these straws will ferment into organic fertilizers, truly realizing the full use of 'straw'." Technician Wang Yang said.
Most of these straws come from surrounding farmers. "One pound of straw is exchanged for one point, and 10 points are equivalent to 2 yuan, which can be consumed at agricultural supplies stations." Jin Wei, deputy director of the Lanting Sub-district Office, said that since the launch of the straw recycling point exchange voucher at the end of April, more than 20 tons of straw have been collected and stored across the street, and more than 650 small farmers have participated in scattered farmers. "Compared with inspecting and disposing of random piles of straw, the cost of this method is lower, and the villagers also support it." Zhang Jiguo, Secretary of the Party Branch of Huajie Village, Lanting Street, said.
At present, Lanting Street also plans to introduce agricultural biotechnology companies to promote the village-level economy and increase farmers 'income while turning waste into treasure. According to the plan, after the completion of the street straw storage and industrial utilization demonstration base, the annual straw storage and storage capacity will reach 30,000 tons, radiating to 8 towns and streets in Keqiao District.
According to statistics from the "Open-air Burning Ban Precision Intelligent Control" platform in Keqiao District, since Huashe Street and Lanting Street launched the "Straw Recycling Action" and the "Straw Exchange Point Activity" respectively, the straw burning phenomenon in the two streets has dropped significantly. In May, the burning point was controlled in single digits, and farmers 'awareness of banning burning was greatly improved.
According to the Blue Sky Office of Keqiao District, in the next step, we will actively promote the implementation of such good practices and tricks in the district. At the same time, we will further increase publicity efforts and guide farmers to participate in it, so as to truly achieve "universal ban on burning and turn waste into treasure".
