Leo-King Environmental Group is among the pioneering companies in China that have been engaged in the collaborative treatment of organic solid waste and the production of biodiesel through resource utilization. The group's biodiesel project has been operational since 2016 and 2021 in the international cities of Shenzhen and Guangzhou.

The group's biodiesel division is responsible for the daily management and technology research and development of biodiesel projects. The division is composed of a core management team that hails from leading universities such as Tsinghua University and South China University of Technology, with a total employee count of over 140.

The group's collaboration with Tsinghua University led to the establishment of enzymatic biodiesel production in China, which operates at normal temperature and pressure, without using strong acid and alkali, and with no pollution emissions, making it an environmentally friendly process.

The high-quality biodiesel produced from waste oil resource utilization has been awarded the EU ISCC, the Netherlands DDC, and ISO9001, 14001, 45001 system certifications. About 90% of the biodiesel produced is exported to Europe.

From 2022, the biodiesel produced by Leo-King Environmental Group has replaced an equivalent amount of petrochemical diesel and has contributed positively to green environmental protection .
