We appreciate the challenge finding the right technology for your input materials. Requirements on pre-treatment of input materials as well as processing of effluents are taken into account right from the beginning. Local regulations are complied with more easily this way and a more efficient overall concept can be realised. Depending on the quality of the produced gas we help choosing the right processing steps for the later use for power generation, gas injection or vehicle fuel.
Our partner for biogas generation is the company Thöni Industriebtriebe GmbH from Telfs in Austria. Thöni has more than 25 years of experience with biogas generation and has realised numerous plants using a dry or a wet fermentation process. Based on the high manufacturing depth and continuous development the plants are characterised by extreme toughness and high reliability.
This process is ideally suited to handle organic waste including bio waste (green or brown bin), green waste, food waste, kitchen waste and the organic part of municipal waste. Within the mechanical processing the input materials are pre-treated and temporarily stored before being continuously fed into the digester where the biogas is produced using the plug flow technology.
The remaining effluent at the end of the process is dewatered by screw presses made from Thöni. The produced biogas can be used to produce energy. Modular plant sizes from 1,400 to 2,250m³ allow an optimal adaption of investments cost to the required capacity.
Within this sizes 20,000 – 35,000 tons of bio waste can be handled annually. The combination of several plants allows for even larger quantities where necessary. The outputs of the Thöni TTV plants are eco-friendly biogas, high quality compost and liquid fertilizer.

The Thöni NATURGAS technology is designed for the fermentation of energy crops and agricultural waste. The feeding of input materials is realised by the combination of a pump for wet materials and a solid feeding device for energy crops.
Within a circular tank the fermentation of the biomass takes place. The tank is equipped with different agitators: slow moving paddles and fast moving mixers. Sedimentation and floating layers are efficiently avoided this way and the release of biogas is supported. Biogas being generated is stored above the tanks, conditioned in the external chemical-biological Thöni desulphurisation and then used within a combined heat and power plant. Alternatively, the biogas can be upgraded to biomethane.
At the end of the process the remaining effluent is separated into a liquid and solid phase. The solid phase is low in odor, is a good fertilizer and can be applied directly on the field. A seasonal storage might be required for the liquid phase before being applied as high quality fertilizer.
