Our goals

Our not-so-secret plan:
Turning waste into profit

Our aim is to build processes for our clients that not only treat hazardous waste but also recycle and reuse it. By climbing the waste hierarchy we help our clients earn money while becoming more sustainable. 

Knowing that there is no such thing as a one-size-fits-all solution we’ve invested heavily in R&D.  

With ranging expertise in separation technology and bioremediation combined with our ability to test and analyze each process configuration prior to implementation we are able to provide a customized offering in a short notice.

Waste to profit

Our focus is to improve profitability by identifying opportunities to convert waste into valuable products.


We invest heavily in R&D. We have to. It's the only way for us to meet rapidly evolving demands from our customers.
