Product Portfolio
  • BDI BioDiesel

  • Clean Energy thanks to multi-feedstock technology

    Our tailor-made BDI BioDiesel plants work with the Multi-Feedstock process we have developed ourselves. This enables various types of raw materials to be transferred into valuable BioDiesel.

    In contrast to conventional BioDiesel processes, the use of BDI RepCAT technology allows us to avoid costly processing of by-products. In addition, the use of a recyclable catalyst significantly improves the quality of the products (BioDiesel and glycerin).

      • BioDiesel applications

          • Types of raw materials

          • The production of BioDiesel from raw materials such as waste oils and fats, as well as virgin vegetable oils, has established itself as a trend-setting path. Nevertheless, there is still enormous potential in untapped raw material to be further exploited.
          • Used cooking oils

          • Used cooking oils are the most important recycling material for BioDiesel production. The largest quantities are generated in industry and commerce. The number of collection companies that specialize in the removal of these substances is increasing worldwide. In addition, the collection of used cooking oils from households offers great potential, as the recycling rate in this sector is still low.
          • Animal fats

          • The use of animal fats is closely related to the production of BioDiesel in Europe. Due to the problem of bovine spongiform encephalopathy (BSE), also known as mad cow disease, the use of animal by-products, which are legally defined as risk materials, is linked to compliance with official requirements and operational controls. The basis for processing these so-called Category 1 and 2 risk fats is the BDI Multi-Feedstock process, which has been approved by the EU as an official waste disposal technology.
          • Trap grease

          • Wherever edible fats and oils are used - for example in the food industry, canteens, restaurants or supermarkets - trap grease can be separated from the contaminated wastewater as a valuable raw material. For this purpose, it is necessary to provide a grease trap before discharging into the sewer system. Thanks to BDI Multi-Feedstock technology, the trap grease obtained is ideally suited for the production of high-quality BioDiesel and, at the same time, a waste and energy problem for many municipalities can be solved. Another advantage is that problems in the sewage system, which can be attributed to improper disposal, are avoided. The best example is the disposal of the fatberg in London using BDI BioDiesel technology. More information can be found in this article.
        • BioDiesel technology

            • BioDiesel

            • We are the benchmark in the engineering and construction of industrial BioDiesel plants. The unsurpassed flexibility in the use of raw materials, maximum yield, low operating and maintenance costs as well as the well-known reliability of our plants guarantee the highest possible efficiency and profitability. Product quality in all cases exceeds the strictest quality standards such as EN14214 and ASTM D6751.
            • RepCAT

            • BDI has developed its RepCAT technology for processing raw materials with a high proportion of free fatty acids (FFA). This innovative process can transfer raw materials containing up to 99 percent FFA. The specially developed system allows the catalyst to be reused within the process, which significantly reduces operating costs. A further advantage compared to other industrial processes is the production of absolutely salt-free glycerin of distilled quality.
            • Technological competitive advantages

              • Maximum raw material flexibility – no limits to FFA content in the raw material
              • Technically maximum yield

            • BDI RetroFit

            • Plant optimisation from the technology leader

              Do you have a BioDiesel plant that was not engineered or built by BDI?
              Are you unable to process low-cost raw materials?

              Make your plant more profitable and future-proof!

              We optimize your existing BioDiesel plant and bring it up to date with BDI technology. The implementation of our proprietary RetroFit program in existing industrial plants increases raw material flexibility and simultaneously improves BioDiesel quality.

              This innovative measure also permits the use of raw materials of inferior quality, such as used cooking oils, animal fats and trap grease. BDI BioDiesel distillation ensures that the quality of the fuel produced remains consistently high even with inferior raw material quality.

                • RetroFit applications

                • Due to rising prices for fully refined vegetable oils and simultaneously decreasing quality of low-cost residues and waste fat materials, the use of highly flexible technologies is necessary. In addition, there is the environmental political will to make energy supply more independent, to process waste and residual materials into clean energy and to become sustainably "greener".

                  Thanks to the implementation of new process steps or an adaptation in the use of operating resources, optimization of original systems can be achieved. Improved raw material pre-processing and adaptation of distillation technology result in a higher output of high-quality BioDiesel.

                  With BDI’s high-FFA process, raw materials with up to 99 percent free fatty acid content can be used. This results in advantages for the plant operator such as the use of new raw material sources, reduction of total raw material costs and reduced consumption of operating materials. The by-product glycerin can also be processed into a high-quality product.

                • RetroFit technology

                • Every BioDiesel plant is unique. Simple standard solutions to improve individual parameters such as yield, product quality or raw material flexibility are therefore ineffective.

                  In order to achieve an optimal result, it is necessary to develop an individual overall concept for each plant and to implement optimal technical solutions. The result is a sustained improvement in plant performance.

                  Our one-stop-shop includes all necessary steps for successful plant optimization:

                          Since 2010, the innovative bioCRACK technology has been essentially driven forward by the cooperative alliance between the Austrian mineral oil company OMV and BDI. OMV supported the project with resources and subsequent processing of the materials, as well as evaluation of the liquid products.

                          Awarded the VERENA Award 2016

                            • bioCRACK technology

                            • In the patented bioCRACK process, solid biomass (e.g. wood or straw) is converted into short-chain hydrocarbons by liquid-phase pyrolysis, using a hot carrier oil at temperatures up to 400°C and under atmospheric pressure. Due to the interaction between biomass and heat transfer oil, hydrocarbons with a high hydrogen saturation are produced, which originate both from the carrier oil itself and from the biomass.

                              This innovative approach only gains economic importance through a decisive technical detail: In the bioCRACK process, a low-cost intermediate product from the petroleum refinery (Vacuum Gas Oil - VGO) is used as heat carrier oil. Normally, VGO is converted only to a small extent into diesel fuel and increasingly into short-chain gasoline, which cannot be sold in this quantity in Europe and must therefore be exported.

                              The bioCRACK technology additionally achieves a significant advantage in increasing diesel production from VGO. We offer this unique, patented technology for petroleum refineries to generate second-generation biofuels.

                              • Realization with minimum technical effort and cost-effective operation

                              • Direct sales of the produced fuel via existing sales channels
                              • Greenhouse gas (GHG) savings of up to 85 percent according to a study by Joanneum Research (2015)
