Managing waste and by-products sustainably

For the last 25 years, Solvakem has added value to approximately 15.000 tons of chemical by-products per year. That’s 15.000 tons of materials annually that aren’t incinerated or dumped in landfill. Our aim is always to favour ‘higher’ forms of waste management on Lansink’s Ladder so we can ensure that fewer limited resources are used and that the carbon footprint is reduced considerably.

Solvakem has more than 20 new projects in the pipeline which will contribute to the valorisation of an additional 20.000 tons of by-products per year.

“Our work is all about creating industrial eco-systems. We aim to reduce the amount of waste that’s thrown away, cut the cost of raw materials, promote the exchange of resources and offer better protections against the fluctuating prices of raw materials.”
– Amaury Rosier, CEO, Solvakem
