Experts from UNIDO and Việt Nam shared their knowledge to evaluate the eco-industrial park model according to the international framework, at a recent online workshop.
Dick van Beers, an expert on eco-industrial parks from UNIDO, said industrial symbiosis was the cooperation between several different facilities.
Such facilities are often geographically close to each other, such as companies and factories in clusters or industrial zones that exchange resources (for example, materials, energy, water and by-products) that can be used as substitutes for products or raw materials that would otherwise be imported from elsewhere or treated as waste.
He also cited examples of industrial symbiosis in some eco-industrial parks around the world.
For example, Kalundborg Industrial Park (Denmark), after applying industrial symbiosis, has reduced energy use, CO2 emissions by up to about 250,000 tonnes a year, water use by 30 per cent and other wastes.
NISP Industrial Park (UK), in seven years, has saved GBP1.3 billion (US$1.77 billion), with additional sales increasing by 1.3 billion pounds, and at the same time reduced up to 39 million tons of CO2.
At the workshop, participants also discussed how to manage eco-industrial parks and provide services for businesses in the eco-industrial parks, key concepts, methods and tools in identifying and implementing RECP, as well as industrial symbiosis. — VNS
