Cadbury' waste water treatment for internal reuse
Cadbury is the one of the world’s biggest confectionery companies. It operates in over 60 countries and works with around 35,000 direct and indirect suppliers. Cadbury used approximately 9 million tonnes of water in 2007. Its water strategy in 2007 was to ensure that all its sites have reduction programmes in place. Part of this strategy can be exemplified by the cocoa processing site in Chirk, UK, which invested in an onsite wastewater treatment plant to clean up effluent arising from manufacturing processes. This has led to savings of approximately 17 million litres a year. As a result, water consumption on site has been reduced by 15 per cent and opportunities to increase this reduction to 50 per cent have been identified. Similar technologies are being deployed in sites in Europe (e.g. Valladolid factory in Spain by reducing water needs by 11 per cent), Russia and Mexico, and work is being done to understand the potential for recycling in each case.
