Using a Thermax biomass boiler, Unilever Sri Lanka has won the country's “national green job award for green energy project”. The award was given in the climate change category for converting agrowaste into energy and containing pollution in a carbon neutral manner.
Unilever Sri Lanka reviewed the options available to make a “fuel shift” from furnace oil to biomass for generating steam for its energy needs. The company had been dependent on furnace oil for 70 years. The shift was to neutralise the high carbon dioxide and sulphur emissions of finance oil, besides its price fluctuations. It decided in favour of a Thermax boiler using biomass – namely coconut shells, sawdust, wood chips as fuel – to generate steam.
