The waste heat recovery system offers textile industries an economic and green solution to save valuable energy.
The system extracts and reuses waste energy from industrial processes instead of dissipating it into the environment, according to the Partnership for Cleaner Textile (PaCT), a programme led by International Finance Corporation (IFC).
Launched in 2013, the PaCT focuses on reducing the environmental impact and resource consumption of Bangladesh's textile sector.
The PaCT said more than 338 factories are using the waste heat recovery systems and gas consumption has annually reduced by 1.26 per cent to 12,74,983 cubic metres from 12,91,122 cubic metres.
Industry operators said the recovered heat can be used for onsite power and steam generation and preheat combustion air.
