AN INNOVATIVE SOLUTION TO RECYCLE COFFEE GROUNDS

At its Joure plant in the Netherlands, DEMB (formerly Sara Lee) was looking to reduce the cost of producing the vast quantities of steam needed to make instant coffee and liqueurs. Veolia set out to develop a cost-effective solution to support the plant's increasing production capacity while reducing its carbon footprint and meeting the critical challenge of recycling by-products from the production process.
 

CLEAN, COST-EFFECTIVE FUEL

Following an in-depth study, Veolia developed an unparalleled, innovative drying and combustion system in which spent coffee grounds from the plant's processes are burned in a biomass boiler to produce steam. Veolia was also contracted to provide comprehensive technical management of industrial utilities including steam, compressed air and cold water in partnership with Veolia Water for wastewater treatment.

Before the Veolia project, our two main energy sources were natural gas and coffee grounds on a small scale. Veolia has helped us save on natural gas by using more grounds. This has led to savings of between €1 and €2 million.
