Qualified industrial chemist and former councillor John Hill has proposed the conversion of Holcim's Cape Foulwind cement works into an eco industrial park in a pitch before Buller's District Council.
Lee Scanlon reported in the Westport News that, according to Mr Hill, the park would generate more jobs than Westport will lose when Holcim disuse their current site, and would result in a decrease in electricity prices for Buller.
Overseas company Veolia has expressed interest in the proposal, having been closely involved in similar operations in the United Kingdom.
Hill envisages the eco park making use of varied forms of waste in the production of energy, chemicals, biogas, bricks and building aggregates.
His plan involves the processing of 100,000 tonnes of solid waste per year, drawn for Canterbury, where it would otherwise end up in the Kate Valley Landfill.
