Corncob high yield ethanol
“Farmers grow corn→Enterprises acquire corn and corn cob to produce functional sugars→Generate biomass residue→Bio-refinery technology to produce fuel ethanol (or replace coal for biomass power generation, or return it to farmers for edible mushroom cultivation materials) Fertilizer returning → Farmers grow corn. This complete "corn chain" is the representative of the development of circular agriculture in Gaocheng City, Shandong Province. Huang Jinzhong, secretary of the municipal party committee, introduced that Luancheng City, as a demonstration city of circular economy in the province, set out from its own advantages in resources, continuously explored the mode of ecological and economic development in the agricultural cycle, effectively changed the mode of agricultural development, and achieved a tripartite benefit in economy, society, and ecology. ".
Corncob extracts xylitol. In Yucheng, before corn was threshed, corncobs became waste. Now they use corncobs to extract xylitol. They have taken advantage of the abundant agricultural resources such as corn and corn cob, and cooperated with the Chinese Academy of Sciences and Shandong University to introduce and develop high-tech biotechnologies to process oligosaccharides, xylose, xylo-oligosaccharides, and various derivative functional sugars. product. Do a good job in the deep development of corn, in the country to achieve the first industrial production of oligosaccharides, erythritol, the first glutamine fermentation production process, so that the value-added chain of corn continues to extend. The corn cobs are used as raw materials to process xylose (alcohol) and use the biogas produced after the sewage treatment to build a power generation project. A series of products such as L-lactic acid and polylactic acid were developed using corn starch as a raw material. Among them, polylactic acid is known as a bioplastic because of its full biodegradability, which has opened up new avenues for overcoming the worldwide problem of “white pollutionâ€. With an annual output of more than 500,000 tons of functional sugar, Yucheng City annually processes 1 million tons of corn and 500,000 tons of corn kernels, and drives more than 200 million acres of high-quality corn planting bases. Only one corncob contributes more than 100 million yuan to farmers every year. China Light Industry Federation is named "China's Functional Sugar City."
Corn cob waste produces fuel and electricity. With the rapid expansion of the functional sugar industry, the amount of biomass waste generated has increased substantially. Under the impetus of the “Industry, research, and investment policy†mechanism, the city has continuously introduced the biomass industry. It took the lead in proposing the concept of "biological refining" and cooperated with Shandong University to develop the "Enzymatic hydrolysis of industrial fiber waste residue to produce fuel ethanol project". 3.8 tons of corn cob waste residue can produce 1 ton of fuel ethanol. Using corn cob waste slag instead of coal to generate electricity, the province has taken the lead in building a biomass thermoelectric project, the Xinhuan Thermal Power Company's 15 MW biomass cogeneration project, generating 450 million kilowatt-hours of electricity annually.
Waste cultivation of edible mushrooms. After the production of functional sugar, corn cob waste can be used as a nutrient base for planting edible fungi, supporting the promotion of more than 1,600 specialized households for mushroom cultivation, and recycling waste after planting edible fungi as fertilizer. With the biomass "complementary chain" industry, corn cob processing forms a closed cycle chain.
At the same time, Yucheng City has actively built a platform for the development of agricultural circular economy. The city is aiming at the “second pioneering†of the provincial-level high-tech development zone in Ganzhou City, doing a good job of technical research and development services and support for “agricultural†brand names and building an ecological recycling high-tech zone. Scientifically delineate regions to guide the establishment of mutual exchange relations between wastes and energy among different enterprises, reduce intermediate costs, and promote mutual benefit and symbiosis. Establish a library of comprehensive utilization of resources, strictly control environmental assessments, give priority to the placement of agricultural recycling economy projects, and prioritize the introduction of “complementary chain†enterprises. Currently, there are 5 state-level high-tech enterprises, 21 provincial-level high-tech enterprises, and an enterprise technology center built. In 26 places, the National Functional Sugar Public Laboratory, National Sugar Engineering Research Center and other institutions played an important role in the research and development of circular economy technology.
Fucheng City's functional sugar formed a corn (core) deep-processing recycling industrial chain and realized a complete cycle from "land to land". The projects such as cellulosic ethanol and biomass power generation have fundamentally improved the level and grade of the city’s circular economy, which has further shaped the city’s “low energy consumption, high output, low emissions, high efficiency, large cycle, and sustainability. "The pattern of development. Since the beginning of this year, the energy consumption per 10,000 yuan of GDP in Yucheng City has dropped by 5.1%, the electricity consumption has dropped by 5.2%, and the energy consumption per 10,000 yuan of industrial enterprises above designated size has decreased by 5.4%.
