Dumpsite Remediation

Cambridge can design and implement the necessary plan and budget to solve the complex issues related to toxic dumps. We can redesign them into modern facilities that process waste in an environmentally acceptable way or close them for good. We focus on the problems our clients face today with an eye on the future demands. This allows us to design plans than do not limit our clients options for long-term solutions.



The Cambridge team consist of experts that have actually operated and ran dozens of waste-to-energy facilities throughout North America. Not only can we design, and build these facilities we can operate them as well.

Our experience as world class facility builders and operators allow us to identify the pitfalls and delays many projects face. With us you will avoid consultant “ping-pong.”
