4 SUEZ NWS' waste business Dawn of the resource revolution The increasing scarcity of natural resources is a global challenge with rising population and increasing density in our cities. Today, only 2.5 per cent of the Earth s water is fresh. We must ensure the world has access to high quality drinking water. Today, 10 million tonnes of waste is produced every 24 hours. We must give waste a second life.
