Green chemistry representing social responsibility


Green chemistry, also known as pollution-free and environment-friendly chemistry, reduces or eliminates the use and generation of hazardous substances. Green chemistry involves organic synthesis, catalysis, biochemistry and analytical chemistry, covering many disciplines. Green chemistry advocates the use of chemical technologies and methods to reduce or terminate the use and generation of raw materials, catalysts, solvents and reagents, products and by-products that are harmful to human health, community safety and ecological environment.


Lansheng Biotech adopts green reactions such as green catalysis instead of the traditional process, which shortens the reaction step, reduces raw material consumption, reduces or avoids the use of toxic and harmful raw materials and completely avoids the generation of large amount of waste from the source.


Concerning traditional processes, technical personnel would continuously optimize of the production process to reduce raw material consumption and waste generation from the source. Meanwhile, various techniques are used for proper treatment, such that solvent and water are reclaimed while solid wastes are recycled and reutilized.



Continuous production process leading agrochemical development


Most Chinese pesticide technical manufacturers adopt the traditional batch process, which has a long period of production, high labor requirement, high energy consumption, unsatisfactory working environment and generation of a large amount of waste. Today, continuous production is a breakthrough in the limited production in batch, providing a high degree of automation, stable product quality, improved yield and increased output.



In the context of the rapid and changing development of the industry, as driven by a strong sense of social responsibility and the sense of mission, Lansheng Biotech has utilized advanced technology and equipment at home and abroad to endeavor to develop a variety of new reaction equipment and separation device, having achieved the continuous production through its unremitting effort and hard try.


The traditional clethodim production process faces the problems of unstable product quality, low yield, generation of a large amount of waste as well as higher cost of production. Through persistent testing, the complex synthesis process of clethodim is brought into a continuous run, stabilizing product quality, making the production process safer and more dependable, allowing for stable operation and easy management of waste treatment facilities. The continuous process effectively improves work safety and the greenness of chemical production.
