Background

Lukas Van Zwieten is a Senior Research Scientist with NSW Department of Primary Industries, located at Wollongbar Agricultural Institute since 1995. Recent work on biochar is Internationally Acclaimed and won the 2007 World Environment Day Award “Meeting the Greenhouse Challenge.” Work has been shown on ABCs Catalyst program and on CNN. Biochar research also received a Commendation from the NSW Premier’s Public Sector Awards. The research directly supports production of renewable energy and climate change mitigation through C sequestration in soil, increased crop production and reduced emissions of soil greenhouse gases into the atmosphere.

Lukas also works on risk assessment of chemicals in the environment. With an industry partner, he is currently commercialising a cost-effective method for the remediation of organochlorines in soil and sediment. Lukas also developed a remediation technology based on bioremediation that has been applied for the clean-up of over 5 million litres of highly contaminated dipping fluid in northern NSW. This has resulted in reduced environmental and human health risk of residual pesticides in the region. Lukas won a 2001 Churchill Fellowship which enabled him to work with Distinguished Professor Suresh Rao at Purdue University assessing risks of endocrine disrupting chemicals in the environment.

Lukas has licensed the CALUX® technology for assessing endocrine disrupting chemicals. Projects have investigated ecological risks to the Sydney Rock Oyster, assessment of EDCs in inland rivers and studies of degradation of estrogens in soils.
