Benefiting from policy support, China's new energy vehicle industry has shown rapid development since 2015, and the lithium battery industry has also developed significantly. However, due to the lithium battery life of about 4-8 years, with the early new energy vehicles into the end-of-life period, it can be predicted that the peak of lithium battery decommissioning in the next few years is approaching, lithium battery recycling industry has great potential for development, and the market has shown a significant trend of explosive growth.

(hereinafter referred to as "BP Recycling"), founded in 2005, is a leading domestic waste battery recycling enterprise, focusing on recycling business, resource business and material business, providing one-stop closed-loop solutions and services for the whole life cycle management of batteries.

As a holding subsidiary of Ningde Times New Energy Technology Co., Ltd, BP Recycling has built a battery industry chain recycling system with complementary advantages in both upstream and downstream, and has taken the lead in solving the industrial problem of "waste reduction" in the field of recycling of waste batteries in the world through the original directional recycling technology. The total recovery rate of core metal materials of BOPP battery products has reached more than 99.3%.

In the process of lithium-ion battery recycling, the positive electrode battery powder has to go through one infiltration and two infiltrations in sulfuric acid solution, and in the process, in addition to generating sulfur dioxide and other easily scrubbed exhaust, it will also generate a variety of insoluble sulfur-containing organic matter exhaust. For example, methyl mercaptan, ethyl mercaptan, dimethyl disulfide, etc., these sulfur-containing organics have extremely low olfactory thresholds and great odorless contributions. In order to solve the management problem of these complex exhaust gases and achieve the standard emission, BOPC has chosen to cooperate with SEED to develop the pilot project.
