Partnering opportunity

Horizontal bag-type anaerobic bioreactor offered for license agreement


The new mobile Horizontal Bag-Type Anaerobic Bioreactor offered by a Czech start-up company is an innovative, affordable and cost-effective product that will enable energy biomass or biowaste producers or processors to obtain a reliable small-scale way of producing biogas for energy use and fertilizer for agriculture. The technology is offered for license agreement.

Partner sought

The technology is ready to be patented and demonstrated. The idea of the cooperation if license agreement, where the licensee will have permition to use the licensed product for a fee or some kind of share in the company, depends on the arrangement.


It is an anaerobic fermentor for biogas production made from a gas-tight membrane bag used for gas holders. The bag is stretched on a steel front of a circular cross-section and enclosed in a ISO steel transport container. Heating is by circulating warm air under and around the bag. The heating can be solved by a classic hot water system, but it is not part of the design. The system may include a homogenization tank for mixing fresh biomass with fluid slurry, circulation pump, and a paddel stirrer. The reactor is suitable for wet or semi-dry small-scale biogas production in areas where low investment costs, mechanical protection against external environment and if necessary easy relocation to a new user are required. Start-up company offers the technology for license agreement.

Advantages and innovations

The main advantage of this device is a simple and cost-effective construction using a pre-fabricated bag made of polymer-textile membrane as a reaction vessel for anaerobic fermentation. Other benefits include the mobility of a device that is built in a steel container, low weight and easy cleaning of the bag-type reactor.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
