Zero-waste industrial management should be introduced in small, medium and large industries to save rivers and other water bodies near them, urged speakers at a seminar organised by Bangladesh Paribesh Andolan (Bapa) yesterday. They also urged that the government makes sure of the set-up and functioning of effluent treatment plant (ETP) in industries.Sudipti Biswas, assistant professor of Ahsanullah Science and Technology University, in a multimedia presentation at the seminar titled "Zero Waste Industrial Management in Bangladesh: Dholaikhal Experience and More--" held at Women's Voluntary Association (WVA) auditorium showed how zero waste industrial management can be materialised in Bangladesh.She said the basic principle of industrial ecology is that, the by-product of one industry becomes raw material for another. Thus generated waste used in other industrial process eventually leads to zero waste because industrial pollutants do not exit anymore, she added.Citing an example Sudipti said if a fish farm, a fish processing and a fish-meal industry are located close by then the waste and sludge from the fish farm and the fish processing industry can be conveniently used as raw material by the fish-meal industry.Industrial area designed with the principles of industrial ecology is known as Eco Industrial Park (EIP), she added.Bapa president Muzaffer Ahmad who presided over the seminar said waste management plan should be based on the types of factories and industries."If river encroachment does not stop now, one day we will face a huge problem as we will not even have the place for releasing treated water," maintained Muzaffer.Standing committee chairman of the Federation of Bangladesh Chambers of Commerce and Industry (FBCCI) Shafiqur Rahman urged the government to provide subsidy and keep allocation in the next budget for encouraging industrialists to set up ETP.Professor of civil engineering department M Firoz Ahmed, professor of Dhaka University Nurul Islam Nazem and project director of waste management of Dhaka City Corporation Tareq Bin Yousuf addressed the seminar, among others.
