Most innovative biodiesel production plant in Europe built by BDI and operated by Envien officially opens on March 11, 2022

(Raaba-Grambach AT/Komárom HU, 14.03.2022): The new biodiesel plant built by Austrian process engineering company BDI-BioEnergy International GmbH and operated by Rossi Biofuel Zrt, a subsidiary of the ENVIEN Group will make an important contribution to sustainable circular economy in Hungary.

For Rossi Biofuel Zrt, building the new plant is a commitment to sustainable innovation and profitability:

  • 150,000t annual CO2 savings
  • 70,000 cars to be climate neutral operated
  • up to 50 new jobs in the region

The ENVIEN Group is one of the largest `groups` of companies in biofuels production in the CEE region and these days, it is also one of the most important agricultural group in Central Europe. ENVIEN is investing strategically in ‘next generation’ raw materials and in the expansion of production capacities. The new production facility at Komárom, Hungary is a multi-feedstock plant using BDI’s patented Repeatable Catalyst Technology (RepCAT). With this innovative technology even the lowest-quality feedstock with high levels of impurities can be effectively processed to standards-compliant biodiesel. The use of a recyclable catalyst further underlines the environmental sustainability of the process.

Sustainable development for the biodiesel production of tomorrow
By producing biofuels from low-quality waste materials, the new plant makes a significant contribution to reaching the targets set by the Hungarian government: to produce 55% less greenhouse gases by 2030 and to be climate neutral by 2050.

The essential step forward with the RepCAT process is its outstanding robustness towards different kinds of waste materials. It can handle a great diversity of waste oils and fats, for example used cooking oil, fat from grease separators or waste from plant-based oil production.

Not only is the RepCAT technology highly innovative, it is also a highly eco-friendly biodiesel process, and was approved by the European Food Safety Authority EFSA in April 2021 as a disposal process for high-risk waste fats.

Markus Dielacher quote: “Being able to design and build this innovative plant for one of the biggest biofuel producers in Europe is one further big success for BDI in Europe. Once again, we have demonstrated our competence in design, engineering and construction of chemical plants to make the world a little bit greener.”

Róbert Spišák quote: “The BDI RepCAT process means we can use a high variety of feedstock, even lowest-quality materials – such as trap grease or animal fats – to produce valuable, high-quality biodiesel. With this technology we can make a valuable contribution to CO2 reduction, and the amount of biodiesel we will produce at this site will be enough for climate neutral operation of more than 70,000 cars.”
