Orllati, Switzerland

Swiss company, Orllati, are using CDEnviro equipment to process contaminated soils and reuse the materials for concrete production.

Orllati, established in 1995, is one of the leaders in construction in French-speaking Switzerland. The Group of companies specialise in asbestos removal, contaminated soil processing, civil engineering, concrete production and much more. The company’s drive to look after the environment is at the forefront of all they do which is one of the reasons that led them to invest in a CDEnviro waste treatment facility for their Bioley-Orjulaz site.


The treatment facility was installed in 2017 and treats various waste streams including contaminated soils excavated from various polluted sites across Switzerland.  A waste that was once sent to landfill is washed and valuable resources are recovered.


The facility is made up of a HYDRO:GRADE and HYDRO:FLO as well as various other components to ensure the effective treatment of this highly contaminated waste. The HYDRO:GRADE offers superior separation of lightweight and fine constituents, through a series of density separation techniques. 


High quality gravel and sand are extracted in the process which are reused to make concrete.  A fine cake product is also extracted and reused in cement production.The HYDRO:FLO system ensure that’s water is not waste in the process.  The water used in the washing process is also treated and reused in the treatment facility once again. Orllati uses the clean outputs products on the same site as their treatment facility in order to reduce transports and negative impacts on the environment. Not only does the solution avoid sending valuable products such as sand and gravel to landfill, but it also reduces the reliance on virgin resources for construction.


With the help of the CDEnviro system, Orllati are leading the way in contaminated soil processing to creating valuable resource for reuse. Orllati are taking on difficult waste streams and in the process, proving their dedication to a circular economy.
