Hejnic

Thesis topic:

Biological production of methanol from waste methane streams

Motivation

Biogas of poor quality or from small sources is often flared without utilization of its energy content. Dissolved methane is present in AD effluents in low concentrations. Treatment of low-strength wastewater is releasing large amounts of dissolved methane to the atmosphere via large water flux through the system. Present technology is able to separate the methane from effluent by stripping it out and also to oxidise it, but the energy content is lost.

Solution

Aerobic and also anaerobic microorganisms are able to utilize methane as substrate. Biological methanol production is proposed as simple method for utilization of waste methane streams.
