We combine wet digestion technology with our biogas conversion technology to create electricity,heat and water purification using a biomembrane reactor at our Greenmills plant in Amsterdam. This allows us to facilitate smart synergies with the local heat network, the regional electricity grid and surrounding companies, such asSimadan and Cargill that are located next door - - who provide us with their waste via a pipeline, optimally recycling it at the Greenmills plant.

How it works

The unique and extremely efficient Orgaworld Greenmills plant was launched in 2010 and processes nearly 120,000 tons of unpackaged supermarket food and other organic waste - including 350,000 m3 of polluted waste water. The incoming organic waste is digested in large tanks. This releases biogas. The biogas is converted into steam, heat and green energy. These products are partially used by Greenmills and the rest is released to the power network. The residual product left over from the processes is transformed into high-quality fertilizer using our 'own' heat.
