PrimeAsia Vietnam poised for solar heating plant breakthrough
06/11/2017
Solar energy has been in use at PrimeAsia’s Vietnamese tannery, located at Ba Ria-Vung Tau, for almost a decade, with the leather manufacturer using solar power to produce hot water. Progressing to using solar energy to produce heat for its manufacturing and wastewater processes is something contractor Arcon-Sunmark has described as “a breakthrough with major potential”.
Use of the solar-produced heat to dry out sludge in the tannery’s effluent treatment plant will have the parallel effect of making water-recycling more effiicient. As a result 90% of the wastewater from the sludge will be recycled for use in the tannery. The solar heating system will contribute an estimated 20% of the facility’s total energy requirement. Occupying 5,000 square-metres, it will be, by far, the largest solar heating plant in Vietnam, Arcon-Sunmark said.
The Danish company’s project and business development maager, Hans Grydehoej, said on announcing the start of construction of the new solar heating plant at PrimeAsia Vietnam: “By Vietnamese standards it is a very big installation that is now under construction in Ba Ria-Vung Tau. PrimeAsia is wholeheartedly endeavouring to reduce the environmental impact of its production and solar heating will contribute significantly as regards CO2 emissions. The installation will offer a direct reduction in the energy costs of the factory, and this reduction will grow bigger and bigger as the energy prices in Vietnam increase.”
Arcon-Sunmark has its own factory in Vietnam, established in 2006. It has been working for some years to “open the eyes” of local manufacturers to the potential of solar heating for industrial processes. It now believes working with PrimeAsia will give it a “solid reference project” that will help it develop the market for large-scale solar heating systems.
