Experts at a seminar on Wednesday called for using modern dyeing chemicals in textile industries in place of traditional ones as it can reduce industrial water consumption by 30 per cent.
This simultaneously minimises hazardous chemical discharge in environment, they said.
The experts came up with the call at a seminar titled 'Greenline Information Day-2016' organised by Greenline Environmental Technology Ltd, a Hong Kong-based textile consultancy and solution provider at a hotel in the city's Khilkhet.
Head of Sustainability of Lidl Germany Alexander David said pollution level in the world is increasing with booming textile industries and it is estimated that around 20 per cent of the world's pollution is contributed by the textile sector.
He said 54 companies in Bangladesh have joined Detox campaign, an awareness programme related to chemical contamination, aiming at discharging zero quantity of hazardous chemicals in the environment by 2020.
Urging factory owners to be more responsible using water and energy, he said currently six factories in Bangladesh have adopted 100 per cent ZDHC- Zero Discharge of Hazardous Chemicals and MRSL-Manufacturing Restricted Substances List.
Greenline Environmental Technology Ltd Chief Operating Officer (COO) Suvro Dev Saha said the target of their water saving technology (WST) project in many garment industries is to find out hazardous chemical pollution in different levels of textile manufacturing.
The textile factory owners can save 30 per cent of water by replacing traditional dyeing chemicals, he said.
He also said around 40 per cent of the dyeing chemicals are discharged as waste products in traditional process while it can be downed to zero using new generation chemicals.
Mr. Saha said around 104 companies are available in the country right now to supply such chemicals that reduce water consumption.
Attending the programme, Bangladesh Knitwear Manufacturers & Exporters Association (BKMEA) Senior Vice-President Mansur Ahmed said global warming has become a big concern of contemporary era and massive industrialisation is a major reason behind this.
Energy efficient and environment-friendly technologies are very much needed to reduce pollution level, he emphasised.
