GICON Bioenergie GmbH

Construction of biogas plants from concept through to commissioning, including infrastructure, gas utilisation or upgrading, and the handling of digestate

GICON Bioenergie GmbH, an independent firm within the GICON Group, develops, plans, and realises biogas plants as a general or engineering contractor. Through the interdisciplinary structure of the GICON Group, with more than 200 employees, and experience gained from the construction of more than 35 biogas plants, project management of all phases – from concept development to permission and on to commissioning and operational optimisation – can be guaranteed from one single source.

For extensive research, project-specific prepatory test trials with original materials can be carried out in the GICON large-scale research facility. A high degree of security for each client’s plants can be achieved. Through use of this systematic procedure, a guarantee for gas yield can be ensured – forming a reliable basis for planning.

Innovative dry fermentation

The GICON biogas process was designed to operate in two steps, with a systematic separation of microbiological decomposition steps. During the first step (hydrolysis), organic components are eluted from the substrate matrix and converted into organic acids and other water-soluble decomposition products. This watery solution (hydrolysate), which contains organics, is fed into the second step, the methanisation process. The environmental conditions are controlled and optimised separately in both process steps. By applying the innovative GICON biogas process, major disadvantages of conventional facilities are omitted.

Wet fermentation of wastes

In waste fermentation plants, mainly commercial kitchen and food wastes are fermented with agricultural wastes (crop residues, manure and liquid wastes) and utilised for heat and electricity generation. Via appropriate adaptation of the process steps (pre-treatment or dewatering, for example) and the fermenter concept, individual concerns of the plant to be erected or the substrate to be fermented can be addressed.
