            During the processing of agricultural products are various residues, which are suitable for biogas production.
            Examples of these are: Press marc (residues), grains (Maltbacklogs leached from the beer production), dregs (residues), pulp (residues
 of starch from potatoes) and other residues.

            The gas yields per ton of fresh material at the different waste materials are 
very different, depending on the dry matter content.
            These waste materials do not count as renewable resources for the purposes of the EEG. they
may be used in biogas plants, the renewable
Ferment raw materials to produce electricity without the bonus of Nawaro compromising the entire system. Different types of organic wastes such as food scraps, stomach and 
Rumen contents of pigs and cattle, from grease residues of commercial kitchens, restaurants and bio-energy crops are not allowed in facilities
be used. For our clients we are daily focussed on revenue maximization.

            Optimal utilization of all possible bonuses under the current circumstances of the EEG, minimal downtime and maximum engine run times and reduction of maintenance expenses are identified as key words here.

            Our experience is our strength. We care for individual requirements and interests of our customers. We design a quite new concept with our customer’s ideas and stay in contact later on. We are flexible, long-term, profit-directed.

                  • NAWARO Damsdorf GmbH und Co. KG

                    The biogas plant in Damsdorf was built in 2007.
                    The plant has an electrical capacity of 2 x 537 KW and a thermal output of about 2 x 500 KW.
                    2011 a satellite block heating and power plant (CHP) was retrofitted with a capacity of 800 kW (electric) and about 780 kW (thermal).
                    TW Biogas and Service GmbH has optimized by remodeling the facility and then started in addition the CHP.
                    A secondary fermenter was fitted with a heater and now serves as a fermenter for the satellite-CHP.
                    New pipes were installed and an additional residue storage was built with a volume of approx 8000 m3. The waste heat is well used by annexing approximately 35 houses, the school located on the site and a files storage, the company's own buildings, such as milking parlor, office buildings and warehouses.
                    The input materials such as corn, rye and green manure are grown on this area and delivered from the agricultural holding Damsdorf Wessels GbR. The substrates are grown within a radius of about 5 km.
                    The fermentation residue comes to the land again as an important and high-quality organic fertilizer. The farm grows additional crops that can be taken for the production of renewable energy use in our region, such as turnips.
                  • Wittenburg

                  • Nawaro Wittenburg GmbH & Co. KG

                    The biogas plant has been built in 2007 with an electrical capacity of 3 x 716 kW and a thermal output of 3 x 680 KW. This capacity covers the power and heat supply of the vicinal building serving indoor cross-country ski possibilities.

                    In 2009 the dry fermentation plant was retrofitted with three separators. The input materials are produced by the agriculture of about 12 farms from the immediate vicinity.

                    The materials used in the biogas plant mainly are corn and green rye. The biogas plant has its own silo, in which the input materials for the whole year can be stored. The separated digestate again is placed at the farmers diposal as economical fertilizer.
                  • Götz

                  • Nawaro Götz GmbH

                    The biogas plant was planned by TW Biogas Betreuungs GmbH and co-directed with TW Bau und Service GmbH and has been completed in 2010. The plant is now in the care of daily operations of both companies.
                    In this plant corn, feed grains, rye and green manure are used to produce biogas. These input materials come from a max. distance of about 8 km at the local farmers. The entire silage areas are located in the vicinity of agricultural farmland. The silage is delivered daily to the biogas plant in order to avoid increased traffic. The fermentation residue is available to farmers as a high-value fertilizer.

                    The biogas plant has an electrical output of 800 kW and a thermal output of about 780 KW. The electricity produced by a gas engine power is fed into the public grid. Thus about 1700 homes can be supplied with electricity out of renewable energy sources. At this location staff training is held.
                    The plant was built on the advanced standard of technology from May 2010 to December 2010. At Christmas 2010 the electricity was initiated. The location of the biogas plant in Götz was chosen with intention in the industrial area of the community in order to use the produced heat meaningful.

                    The total heat of the 800 KW engine is supplied to the local Center for Trade of the Chamber of Crafts, Potsdam. Thus, all training rooms and workshops are heated and supplied with hot water.
                  • Bad Langensalza

                  • NAWARO Bad Langensalza GmbH

                    The biogas plant in Zimmern is built on the area of a dairy cattle plant, where the input materials dung and manure arise right next to the biogas plant. The generated heat is used by in the existing building, workshop, office and social building of the dairy farm and a neighbour farm.

                    The thermal power and pipeline system have been implemented through the TW biogas team. The plant was built in that way that a future use of other substances is ensured. The existing storage of fermentation waste was included and involved in the planning of the biogas plant. This facility is located in a drinking water zone, so that special legally requirements had to be considered.

                    The electrical output of the plant is 600 kW, the thermal performance is at about 570 KW.

                    The already existing menure slurry tank on that terrain was renovated and used as space for the substrates of fermentation residues in the cases of emergencies. The whole system is in a collecting tank, that even in emergency situations no water contaminating substances penetrate into the soil. With the current supply from a 600-kilowatt engine electricity comes into about 1.100 households.

                    In the Nawaro plant additionally corn, beets and green rye are used. The required input materials for the plant come from the local farmer. The maintenance and service at the biogas plant and the CHP will also be performed by TW Bigogas Bau und Service GmbH.
                  • Trechwitz

                  • Nawaro Trechwitz GmbH & Co. KG

                    The TW Biogas Betreuungs GmbH is projecting this system.

                    It will have an electric power of 600 KW and a thermal output of 570 KW.

                    For this project a fermentation tank is scheduled with a gross volume of 4.200 m3 and a fermentation residue tank in the size of 6.200 m3. The existing silo, which should be used for the storage of the input material will be redeveloped by TW Biogas Bau und Service GmbH.

                    It is intended to install a local heating network providing 40 houses.
                  • Sagard

                  • Jasmunder Biogas GmbH & Co. KG (Sagard-Rügen)

                    This biogas plant will have 825 kW electrical power and 800 KW of thermal power.

                    In this plant a production of 1.400 m3 raw biogas will be generated. Through the Energy EWE AG, a gas treatment plant will be built in which the raw biogas is converted into natural gas quality can be injected into the public gas supply.

                    At this location, three fermentation tanks with 4.200 m3 gross volume and three residue tanks with a size of 6.500 m3 will be built. The collecting tanks have a gross volume of 300 m3.

                    For this project an extra separation system will be developed. The existing silos are being renovated and one silo system has to be demolished and rebuilt.

                    A special challenge in this project is to involve an existing co-fermentation biogas system at this site. 

                  • Roggendorf
