Product Portfolio
  • Technology and Services

      • Biodiesel & Retrofit

      • BDI's biodiesel technologies

        are specially designed to convert even challenging raw materials such as animal fats, used cooking oils, trap greases, and vegetable oils into high-quality biodiesel. The technologies can process all kinds of feedstock containing between zero and 99 percent free fatty acids (FFA). The quality of the biodiesel produced exceeds the most stringent quality standards in accordance with EN 14214 and ASTM D6751. We design and build customized biodiesel plants offering maximum feedstock flexibility for our customers and modify existing plants to augment their efficiency and sustainability.

        • Maximum feedstock flexibility: No limits on FFA content in raw material
        • Reusable by-products: Process does not generate new waste streams
        • Decades of experience: Global player in international industrial plant engineering
          • ANIMAL FAT

          • In Europe, biodiesel production is closely linked to the use of animal fats. Animal fat typically contains five to 35 percent free fatty acids (FFA). This varies depending on its source and storage conditions. The longer it is stored, the more the fat degrades, which also dramatically increases the sulfur content. Another challenge in processing animal fats is the often high proportion of polymeric plastics such as polyethylene. When converting animal fats to biodiesel, suitable measures such as appropriate fat processing or separating out the polyethylene must be considered.
          • BY-PRODUCTS OF PALM OIL PRODUCTION

          • Residues and by-products from the palm oil industry, such as palm oil mill effluent (POME) and palm fatty acid distillate (PFAD), are well-suited as feedstock for the production of biodiesel. PFAD is generally a clean raw material with a high FFA content and exhibits little variation in terms of quality parameters, but is more expensive compared to POME. Generally speaking, the water content, metal, sulfur, and other parameters in POME can vary greatly, depending on where it comes from and how it is delivered. A biodiesel process for the processing of by-products from palm oil production must therefore be designed in such a way that it is able to reliably compensate for significant fluctuations in quality.
          • INDUSTRIAL WASTE FATS

          • Industrial waste grease, such as yellow grease, brown grease, black grease, or trap grease, is typically a mixture of organic waste oils and fats, as well as residues from wastewater systems. Due to their origin, these fats contain high levels of moisture, impurities and insoluble substances, and the triglycerides in the fats and oils may be chemically highly degenerated. When designing the biodiesel process, these challenges must be considered.
        • Technology

            • MULTI-FEEDSTOCK

            • The BDI multi-feedstock process can convert a wide range of raw materials such as animal fats, used cooking oils, trap greases, and vegetable oils into high- quality biodiesel that exceeds the highest quality standards. Flexibility in terms of the raw materials used, maximum yield, low operating and maintenance costs, and the renowned reliability of our biodiesel plants guarantee the maximum possible cost-effectiveness.
            • REPCAT®

            • With the fully continuous RepCAT® process, BDI has developed biodiesel technology for processing waste-based raw materials consisting of up to 99 percent free fatty acids (FFA). The use of a heterogeneous catalyst that is recycled and recirculated back into the process is the key to maximizing the efficiency of this technology. Another advantage of this process is the recovery of salt- free, distillate-quality glycerin as a by-product.
            • RETROFIT

            • Producers of biodiesel face numerous challenges when attempting to give their plants an economic edge. However, off- the-shelf solutions designed to improve individual parameters such as yield, product quality, or feedstock flexibility prove ineffective. With the BDI Retrofit program, entire existing biodiesel plants are upgraded to the state of the art with the latest technology. To achieve optimum results, it is necessary to develop an individual master concept for each plant in order to implement the best possible
          • Advanced PreTreatment

          • Renewable diesel and sustainable aviation fuel

            in the form of hydrogenated oils and fats (HVO and HEFA) are becoming increasingly important, but strict requirements must be met regarding the impurities in the oils and fats used, in order to minimize negative effects on downstream process steps. Pretreatment is therefore a crucial step in the efficient and cost-effective production of renewable fuels, and the processing of waste materials in particular requires the best possible treatment technology.

            • Robust and efficient: Centrifuge technology and process design optimized for waste oils with minimum oil losses
            • Modular process units: Customized solution for each type of raw material and impurity
            • Patented system: Polyethylene separation via a filterless process
              • USED COOKING OIL

              • Used cooking oil (UCO) is the most important waste-based raw material for the production of renewable fuels such as sustainable aviation fuel (SAF), with the largest volumes being generated in industry and commerce. Relevant raw material parameters include its metal and phosphorus content, as even small amounts of these substances can negatively impact downstream processes. The quality of used cooking oil varies greatly, depending on both the origin of the oil and the method of collection. In general, a multi-stage purification process is required to prepare UCO for the production of renewable fuels, but high-quality oils require significantly less purification.
              • ANIMAL FAT

              • Animal fats are an increasingly important feedstock for renewable diesel and sustainable aviation fuel (SAF) production. The quality varies, depending on their origin, processing method, storage time, and season. High temperatures and long storage times promote chemical and biological decomposition of the fat, increasing both its sulfur and nitrogen content. Another problem faced in the processing of animal fats is the proportion of polymeric plastics such as polyethylene, which can come from the ear tags of livestock or other waste plastics. A special filterless process has been developed to process animal fats with a high polyethylene content.
              • POME (PALM OIL MILL EFFLUENT)

              • The oil content of wastewater from palm oil production also serves as a valuable feedstock for sustainable fuel production. The combination of impurities, water, solar radiation, and long retention times in separator basins allows for chemical and biological decomposition of the oil, resulting in the formation of degradation products. Processing this to yield renewable fuels requires a special design and multi-stage treatment process to not only overcome the challenging properties of the oil, but also to achieve the required product specifications.

                    • Energy independence and carbon credits: Local production of biogas from on-site by-products or waste
                      • BREWER'S SPENT GRAIN

                      • Approximately two billion hectoliters of beer are produced worldwide each year. For every hectoliter produced, the main by-products of the brewing process are 20 kg of spent grains and yeast. Anaerobic fermentation of these waste products can cover up to 100% of a brewery's heat, energy, or electricity needs. This efficiently and sustainably replaces energy that would otherwise be generated using fossil fuels, helping breweries move toward energy independence and zero carbon emissions.
                      • FOOD PRODUCTION

                      • In the EU, about 100 million metric tons of food are wasted each year, which equates to around 200 kilograms per person. This significant amount of waste could be put to good use if its carbon and hydrogen content were to be used for biogas production. This could provide a significant portion of the energy needed to power food processing plants or the truck fleets of waste collection companies.
                      • POULTRY INDUSTRY

                      • A chicken produces approximately 200 grams of manure each day. A typical chicken farm produces thousands of metric tons of manure each year. Slaughterhouses also produce large amounts of waste, wash water, and rinse grease. All of these resources are optimal energy sources and are ideal for use in a BDI Biogas plant. The biogas produced can be used on site or, after purification, be fed into the gas grid at a profit.
