Key innovations
The innovation of this technology lies in multiple feeding processes, compatible with high FFA raw materials (RepCAT), achieving extremely high raw material flexibility. Use recyclable catalysts to avoid by-product disposal, significantly reduce costs, increase the production of biodiesel and high-quality salt-free glycerol, and reduce waste.
Potential economic benefits
This technology significantly reduces production costs by utilizing cheap waste, avoiding expensive treatment and recovering catalysts; at the same time, it improves the quality of biodiesel and glycerin, increases the added value of products, and achieves high economic benefits.
Potential climate benefits
This technology efficiently converts a variety of waste oils and fats into high-quality biodiesel, directly replacing fossil fuels and significantly reducing transportation carbon emissions.

Solution details

The tailor-made BDI biodiesel plant is used in conjunction with a self-developed multi-feedstock process. This allows various types of feedstocks to be converted into valuable biodiesel. BDI has also developed RepCAT technology for processing raw materials with high proportions of free fatty acids (FFA). This innovative process converts raw materials containing up to 99% FFA, avoiding expensive by-product processing. The first factory using this process was built in Austria. Compared to standard biodiesel processes, RepCAT uses low-cost recyclable catalysts, and the system it has developed allows the catalyst to be reused in the process, avoiding complex by-product processing, significantly reducing operating costs and significantly improving product quality (biodiesel and glycerol). Another advantage compared to other industrial methods is the production of distilled quality absolute salt-free glycerin.


- Very high raw material flexibility, with no limit on the free fatty acid content in raw materials. Different types and sources of waste oils and fats, such as used edible oils, yellow grease, animal fats, trapped oils or residues from vegetable oil refining, can be processed into high-quality biodiesel.

There is no limit to the free fatty acid content in raw materials

- Maximum production within technical constraints

- There is no waste in the process, but instead produces reusable or saleable by-products

- Well above all applicable biodiesel quality standards

- Years of international experience in large-scale industrial implementation

- Using BDI RepCAT technology avoids expensive by-product processing

- The use of recyclable catalysts significantly improves the quality of products (biodiesel and glycerol)
