Biodiesel Upgrade from the Valley 

The American Renewable Energy Group has awarded a contract, for the modernization of its biodiesel plants in Germany, to the technology leader from the Green Tech Valley, BDI-BioEnergy International. The refurbishment will enable cost-effective conversion of low-quality waste oil and fats into pure biodiesel sufficient for 300,000 cars.

Biodiesel – an environmentally friendly alternative

As a climate-friendly alternative to fossil-derived diesel, biodiesel is considered one of the green fuels of the future. It is produced from sustainable and regionally available raw materials, or from commercial and industrial residues and waste products, for particularly effective use of resources. In the latter case, this is enabled due to innovative technology solutions from the biodiesel industrial plant manufacturer BDI. The company specializes in extracting non-toxic, biodegradable fuel from waste oil and high-risk fats. These waste materials are processed into clean energy. BDI will now retrofit two production plants for the American biodiesel manufacturer, Renewable Energy Group, that will allow them to process inexpensive waste materials into high-quality biodiesel.

As Markus Dielacher, Managing Director of BDI, comments: “Through our innovative RetroFit program, we are upgrading the two biodiesel plants to a completely new level, both in terms of technology and costs. The result is unparalleled flexibility in the use of raw materials, maximum system availability and a quantifiably valuable contribution to the circular economy and CO2 reduction”. The ecological balance is impressive: Each liter of green fuel made from waste fats reduces greenhouse gas emissions by almost 90% compared to fossil diesel and is completely biodegradable within 21 days.

On the road with biodiesel: Net-zero CO2 for 300,000 diesel vehicles

This is the result that the customer will achieve, in collaboration with BDI, by retrofitting the plants. The entire plant capacity of 200,000 tonnes per year will be converted to waste-based oils, as part of the upgrade. This gives an equivalent saving in CO2: The reduction in pollutants corresponds to operating some 300,000 diesel vehicles with net-zero CO2 – a large and significant contribution to the reduction in greenhouse gases. The improvements also give a further advantage: Greater independence from expensive energy imports.
