In the past, eight peaks had failed to recycle L-methionine in the production of rectified waste liquids, and the environmental pressure was greater. In June of last year, the company set up a task force to start waste recovery and utilization. The process recycles the rectified waste liquid as an important raw material for the synthesis of L-methionine, turns waste into treasure, not only realizes zero discharge of waste water, but also reduces the production cost of L-methionine by 0.82 million yuan per year. The eight peaks of pharmacology "detour" economic benefits 2.1 million yuan.
The production of L-methionine by Hefeng Pharmaceutical is a national key new product recognized by five ministries and commissions such as the Ministry of Science and Technology, and over 75% of them are exported overseas.
