How to promote green development, circular development and low-carbon development?

This is a relatively large and wide problem, involving a wide range of industries. Green, recycling and low carbon are often interrelated. The green development model is also low-carbon with high probability, and the utilization of resources in development will not be one-way and one-off. Instead, some of them will be recycled in various ways and added to the development model again.

Low-carbon recycling of organic waste in urban and rural areas is an important starting point to solve resource and environmental problems, improve cultivated land quality and promote green, low-carbon and high-quality development of agriculture.

Let me give you an example. As we all know this week, China is a big agricultural country. Field crops such as rice, wheat, corn and cotton are planted here, as well as countless cash crops such as fruits, vegetables and mushrooms, as well as Chinese herbal medicines needed by the Chinese medicine industry. Agricultural production produces a large number of agricultural and forestry organic wastes, such as straws, tail vegetables, mushroom residues, aquatic plants, etc. Most of these wastes are directly discarded.

For example, the recovery of straw has always been a difficult problem for farmers and the government.

Burning it will not only pollute the environment, but also be in danger of fire, and it will waste organic matter useful for crop growth in straw. Don't burn it. It is not appropriate to pile so much straw in the field. Chopped straw can only be returned to the field, and the cost of the treatment process needs to be considered. Some of them are pushed into rivers, directly turning the lack of oxygen in rivers and lakes into "stagnant water".

As a service provider of circular economy, SmithKline Biotechnology (Shanghai) Co., Ltd. focuses on the recycling of organic wastes in urban and rural areas, recycling most organic wastes in urban and rural production and life, and achieving the development goal of win-win economic development, resource utilization and ecological environment.

Using the core technology of biomass carbonization and carbon bacteria compound fermentation to produce fertilizer, SmithKline Bio-made new biochar-based products from urban and rural organic wastes such as straw, branches, waste wood, tail vegetables, mushroom residue, aquatic plants, biogas residue, feces, agricultural and sideline products, and returned them to the field for application.

The biological innovation model of SmithKline has realized the efficient resource utilization of waste, soil fertility, soil improvement, pollution remediation and carbon fixation and emission reduction.

Lignified wastes such as straw are made into biochar.

Step 1: SmithKline Bio-made biochar from highly lignified wastes, such as straw, fruit tree branches and waste wood.

At present, the industry pain points of making biochar from high lignified wastes such as straw, branches and waste wood are the adhesion of tar to the machine and the acid rot of retting liquid during carbonization, as well as the high energy consumption and unsustainable carbonization process. The content of biological innovation of SmithKline is to convert the hydrogen coke gas produced in the carbonization process into heat energy for the carbonization system. The characteristics of this technology are zero tar, zero retting, zero energy consumption and the sustainability of biomass carbonization.

Low lignified waste, such as tail vegetables, mushroom residue, etc.

Step 2: Using the core technology of biochar-bacteria compound fermentation and fertilization, a new biochar-based fertilizer is made from biochar and low lignified wastes such as tail vegetables, mushroom residues, aquatic plants, biogas residues, manure and agricultural and sideline products.

SmithKline Bio-is the establishment unit of the industry standard of biochar-based organic fertilizer in China.

Industry standard of biochar organic fertilizer

Lin Zeng, deputy secretary of the Party Committee of Shanghai Academy of Agricultural Sciences, said that biochar is a new research hotspot of cultivated land soil biological improvement technology at home and abroad. As a new functional soil improvement material imported from outside, biochar will directly or indirectly participate in the ecosystem and soil nutrient cycle, which will have an important impact on soil quality and overall improvement of soil structure. (For details, please refer to official website, Ministry of Agriculture and Rural Affairs-news "Soil for Green Development of Shanghai Agriculture").

Bio-carbon-based fertilizer is based on the microporous structure and adsorption performance of bio-carbon. By mixing, it creates a benign microenvironment with heat preservation, moisture retention, nutrition and no ultraviolet radiation, provides a shelter for microorganisms, and realizes the compound synergy of carbon and bacteria.

Since the "Thirteenth Five-Year Plan", the Ministry of Agriculture and Rural Affairs and the Ministry of Science and Technology have carried out research and development of comprehensive technologies for reducing and increasing the efficiency of chemical fertilizers and pesticides. In the national key research and development plan, projects such as "Development of biochar-based fertilizer and microbial fertilizer" and "Recommended method and limit standard of fertilizer nutrients" were deployed, focusing on the carbon-nitrogen transformation mechanism, microbial reconstruction and organic-inorganic balance under the action of straw biochar and exogenous microorganisms (fertilizers). It is believed that the development and utilization of biochar-based fertilizer will be the backbone of agricultural fertilization in the future.
