Useful information about Green Energy

All from a single source. Our guiding principle. Your benefit.

We from Green Energy are of the opinion that a professional consultation for the realisation and construction of biogas plants should be based on own experiences. This is something you can rely on us and our experienced technicians to 100 %

Over the last 15 years our team of experienced experts in the biogas business has accompanied more than 250 plants throughout Germany with concept planning, the realization and throughout the ongoing operation. This Know-How makes us one of the leading companies in terms of biogas-technology.

Our daily work is not all about the construction of individual biogas plants but first and foremost about the development of custom and coherent  biogas concepts for a future-oriented energy supply of your business.

This is where we bring in our longtime experiences: With our own plants which we build since 1998 and our employees, who are mainly from the agricultural business we know what is important to you. True to our motto “From practitioner to practitioner” we develop economical concepts fitting for your business based on your ideas and wishes. This applies for the optimization and expansion of already operating plants as well as for the planning and realization of new projects.

With training and further education courses, with answers to your questions for the ongoing operation, with solid information regarding current issues or if assistance with the completion of a form is needed.

Any questions regarding the topic biogas plants? We are pleased to give you the answers . Comprehensible and practical from practitioner to practitioner.
