German cement company Heidelberg Cement Group has signed a six-year contract extension with waste management company Shanks Group for the supply of its Icopower energy pellets.
Under the contract, Icopower, part of Shanks’ Solid Waste Division will supply the company with an increased volume of 54,000 tonnes per year of the pellets, derived from commercial waste.
Waste as a fuel has been a popular choice for cement kilns due to its lower cost. Without the use of waste derived fuels, it would be difficult for many cement plants in European countries to keep competitive.
The production process includes a combination of sorting, drying and pelletising technology. The fuel is used to power cement kilns and is also used to produce cement clinker.
In a statement Shanks said: “Unlike solid recovered fuel (SRF) or refuse derived fuel (RDF), Icopower energy pellets are not classified as a waste product in the Netherlands.”
