Sirius are currently remediating significant hydrocarbon contamination on a site in Teesport using our Soil Treatment And Recycling (STAR) System. The site is going to be the home of the £900 million Tees Renewable Energy Plant (Tees REP). The Tees REP is a 299MWe biomass combined heat and power plant which will be the world’s largest new-build biomass plant.
