Organic waste and food waste are a valuable resource for generating energy in biogas plants. By fermenting this organic waste, not only can waste volumes be reduced, but renewable energy can also be generated in the form of biogas. This helps to conserve fossil resources and reduce greenhouse gas emissions. Our engineering office offers customized solutions for the efficient use of organic waste and food waste in biogas plants. With our many years of experience and technical expertise, we can help you to plan and operate your plant in the best possible way in order to generate sustainable energy and make a positive contribution to environmental protection at the same time.

• Biowaste
• Kitchen waste

Biowaste

Biowaste is separately collected organic waste generated by households. Depending on the region or country, biowaste may also contain garden waste such as grass cuttings or green waste and may feature seasonally fluctuating quantities and qualities depending on the climate. Therefore the consistency and the energy content vary. The impurity content and degree of incorrect sorting varies considerably. The processing biogas plant must address this by using specified processing technology and a customised fermenter type.

Kitchen waste

Kitchen waste is separately collected waste from commercial kitchens, restaurants and canteens. The consistency is usually mushy or liquid. Due to its energy content and water content, it is better to use biowaste and kitchen waste in biogas plants, rather than making thermal use of it or composting it. However, its often high and greatly varying impurity content makes it difficult to use in biogas plants. Here, specific fermentation processes and carefully planned pre-treatment are necessary. Usually, hygienisation also needs to be included in the process. Using the digestate can be problematic due to the impurity content. If you are planning on using the digestate, this must be taken into consideration when developing the process.
