"The Southland Energy Conference next month will be looking at increasing the use of biodigestion as part of Southland's energy future. Biodigesters take the methane produced by effluent and use it to generate electricity. The technology offers farmers the chance to cut down their energy bills and potentially even sell electricity to the national grid. Biodigesters have worked on a small scale in New Zealand, but the existing technology, involving large tanks, is expensive and uneconomic, prohibiting more extensive systems. Venture Southland enterprise and strategic projects co-ordinator Karyn Owen said new biodigestion technology, developed by Niwa, could pay for itself within three years, up from about 15 years with current systems"
