Assessment of the effects of combustion of waste, oil and health effects associated with the use of waste oil as a dust suppressant

August 2000, Ref. TR97

The Ministry for the Environment commissioned a report from Woodward-Clyde on the environmental impacts of burning used oil and spreading it on roads. Woodward-Clyde’s findings formed the basis for discussion in Recovery, reuse and disposal of used oil in New Zealand: issues and options.
