Accra:A new approach using locally available rice husk and husk powder could revolutionize the treatment of textile wastewater by replacing expensive de-colouring agents. This development is expected to make the process more affordable and environmentally friendly.
According to Bangladesh Sangbad Sangstha, Sabrina Mostafa, a Senior Scientific Officer at the Bangladesh Council of Scientific and Industrial Research and a PhD researcher at RMIT University, presented her findings at a discussion held at the Ministry of Science and Technology. Her research, titled "Process development for the treatment of wastewater from textile industries in Bangladesh," highlights the potential of rice husk as a viable alternative for removing toxic dyes from wastewater.
The innovation is designed to help industries comply with the government's 2024 environmental guidelines, which require that the colour units in wastewater be maintained at or below 150. Using rice husk in treatment processes could significantly lower costs and improve sustainability in the textile sector.
Dr. Narshad Haque, participating virtually from Australia, emphasized the importance of this method for making Bangladesh's textile industry more competitive globally. He stressed the role of local natural materials in reducing costs and enhancing the sector's eco-friendliness.
Science and Technology Secretary Md Anwar Hossain called for collaborative research efforts between BCSIR and business bodies like BGMEA and BKMEA to ensure the effective treatment of wastewater. He underscored the need for reducing chemical dye usage and forming partnerships with local chemical manufacturers to support sustainable practices.
The meeting also discussed plans for field piloting the new technology through the "Australia-Bangladesh Innovation Centre," aiming for widespread industry adoption. Participants included prominent figures such as BKMEA President Mohammad Hatem and representatives from various organizations committed to advancing this eco-friendly initiative.
