Residues turned into raw materials.

Biogas plants are an environmentally friendly and worthwhile investment for local authorities, agricultural businesses and waste disposal companies in Germany and other countries. The Amendment to the German Renewable Energies Act has extended the state  subsidization of the generation of energy from liquid and solid manure, residues and energy plants. With the aid of detailed preliminary studies, individual process development, correct applications to the local authorities, short delivery, construction and commissioning times, we take advantage of all the possibilities of obtaining subsidies and  optimizing your biogas plant.

This includes choosing a suitable location and the locally available raw materials, as well as optimal use of the waste heat. Turnkey biogas plants from EPC guarantee stable fermentation processes with maximum yield, minimal operating costs and maximum operational safety.

 

The system solution from EPC for fermenting feedstocks comprises a single-phase, mesophilic biogas plant, which uses a continuous wet fermentation process. In wet fermentation, the fermenting substrate remains stirrable and flowable so that it can be thoroughly mixed during the process, thus ensuring a good exchange of nutrients and energy between bacteria and substrate. The residue from this fermentation process is then used as an agricultural  fertilizer.

We support the generation change: The processes we use to produce first generation bioethanol from starch and sugar-rich plant material have been tried and tested many times. They work reliably and are extraordinarily efficient.

As the migration to the second generation progresses, we can offer you our modern plants, which produce bioethanol from, for example, lignocellulose. This gives you an excellent alternative to the use of first generation raw materials, for which the foodstuffs industry also competes.

Xanthan is the most important, commercially used exopolysaccharide (EPS) with pseudoplastic properties. It is usually produced by the biotechnological fermentation of Xanthomonas campestris. Xanthan can be produced extremely cheaply, as the producing microorganism converts between 60 and 70 percent of the substrate when grown on glucose or saccharose.

The viscosity controlling properties of xanthan make it a preferred gelling and film-forming agent in the foodstuffs industry. Xanthan is also used in some specialist fields, such as crude oil and ore extraction. Xanthan is an approved food additive in Europe, with the assigned number E415.

EPC's specialists supervise the experimental process and optimized the plant parameters. The process is simulated in pilot scale, and the data required for the scaling up procedure are determined. The methods developed in laboratory scale can be used with a large scale-up factor for operations in the technical production plant.

Our engineers are principally involved in processes, in which the chemical, mechanical and microbiological transformation of substances is accompanied by a material, heat and impulse exchange. These processes usually behave differently at small laboratory scale than they do at large production scale; the scale-up is our expertise!

Our unique plants take process  optimization into a new dimension to make them more profitable. Well-developed technologies and efficient plant designs enable our customers to produce select, high-quality cereal products at internationally competitive prices. The planning gives top priority to the specific requirements of the demanding foodstuffs industry. EPC applies a quality management system, which is certified according to ISO standards.                                                                                             

Fermentation technology is the part of biotechnology that develops and runs plants to produce or convert substances by biological processes. We distinguish between three types of biological processes: biochemical processing, enzyme and fermentation methods. 

Whereas the enzyme method uses enzymes as biocatalysts, the fermentation method uses the natural biochemical reactions of living cells, which create and transform substances. The main priority is for all the products to be  characterized by perfect quality and pioneering innovation. The EPC Group is conscious of these quality standards, and constructs fermentation plants on the basis of the latest technologies that conform  to the requirements of Food and Drug Administration (FDA) and Good Manufacturing Practice (GMP).

Proteins are essential building blocks in plant and animal metabolisms. They are macromolecules composed of amino acids. Their tasks are to transport important substances, act as catalysts, and to detect and pass on signals.

As some essential proteins cannot be produced by the organism itself, they have to be added, for example, to animal feed as a nutritional supplement. The resulting high protein fodder has muscle-building and performance enhancing effects in comparison to conventional animal feed.

Vegetable proteins are mainly obtained as by-products from the press residues of oil pressing and extraction processes. Depending on the type of raw material or the use of the product, the press cake is processed by either an "alcoholic" or an "aqueous" method.

Alcoholic extraction, usually with ethanol, achieves a higher yield and a purer protein, but more apparatus is required for the more intensive purification of the protein.

Setting the pH value is crucial to obtaining optimal separation of the protein by means of acid-base washing. We offer integrated concepts for controlling the recirculation of process water and water treatment, which minimize process costs and ensure environmentally friendly operation.

The selection of the most suitable process for obtaining protein is based on our experience in the fields of plant engineering and operational management, and an evaluation of the current market situation. We collaborate intensively with experienced, well-regarded equipment suppliers and our customers to work out an optimal, profitable and goal-oriented process variant.

Protecting the environment always plays an important part in our concept. We reduce the quantity of waste water substantially by purifying the process water internally, and recycling it back into the production. Our concepts do not just save water, the use of energy-efficient technologies also makes them very economical. However, such complex plants are only efficient if all parts of the plant are optimally linked energetically, have viable energy recovery, and make full use of the energy. Optimal design of the ancillary plants also increases the efficiency of the overall plant.
