Working with Duckweed since 1993

BTWM has almost two decades' experience in integrated wastewater management systems. We have installed systems in sites across Australia: from the NSW-Queensland border to Darwin in the far North. The company has worked with researchers at universities in Australia and overseas, as well as provided consulting services to a local and State government agencies.

BTWM remains at the cutting edge of technology. No other private company has such extensive experience in the design, installation and maintenance of duckweed-based wastewater treatment systems.

The company has a world-wide reputation. Its research is referenced in countless journals articles, technical reports and academic monographs.
