Our Business
At Thalia Waste Management, we are creating a future to be proud of. We think differently, questioning everything, enabling us to develop progressive waste into energy solutions and services. Being motivated, tackling problems together, inspiring others to take responsibility, making a difference, being ambitious and contributing value.
We operate the best technology available across our four strategic sites in North Yorkshire, Milton Keynes, Cambridgeshire and the Isle of Wight. Our technology includes everything from mechanical and biological treatment, traditional mass-burn energy from waste and material recycling technologies to in-vessel composting, advanced thermal treatment, innovative small-scale energy from waste and anaerobic digestion. In a single year we process 300,000 tonnes of waste that is turned into energy. This generates the same amount of energy as approximately 600 million solar panels. Similarly we recycle circa 95,000 tonnes of waste.
