Wastewater is a huge challenge, not least in developing countries and emerging markets.
Consequently, Indian authorities have tightened wastewater regulations and introduced guidelines for Zero Liquid Discharge (ZLD) for major water consuming industries. To assist companies in complying with regulations, Rochem
Separation Systems (RSS) has developed a modern and energy-efficient wastewater recycling and ZLD solution that can recover 75 to 80 per cent of the water from wastewater. The plants are provided on an operating lease basis to individual companies, which are charged a fixed and variable fee.
The upfront cost of installing the turnkey plants is financed by Roserve, a joint venture set up by RSS and the Danish Climate Investment Fund managed by IFU. Total investment is EUR 22.8 million of which IFU has provided EUR 4 million in equity. Due to local financial institutions’ reluctance to finance innovative business models, Roserve is instrumental in scaling up sales and fast track the adoption of wastewater recycling in India. Roserve has so far established
30 plants in India and the solution has even greater potential.
