Integrated Solid Waste Management Solutions

Construction Site with Solid Waste Measurements

CDM Smith supports you in all matters related to solid waste management and landfill planning. We develop comprehensive and integrated solid waste management strategies, including advanced collection systems, strategic disposal and material flow concepts, increase resource efficiency, and assist in energy recovery from waste – whether through mechanical-biological treatment (MBT), advanced thermal treatment or efficient landfill gas utilisation. Fully aligned with circular economy principles and sustainable development goals, our approach ensures minimal environmental impact and maximum resource recovery.

How We Support Your Solid Waste Management

From new construction and expansion to safe landfill closure, we guide you through every step, from site selection and permitting to successful implementation. Our services include the careful selection of suitable sealing systems, effective leachate treatment, optimised gas extraction and utilisation. We also provide expert support for the remediation of legacy landfills, the treatment of contaminated soils, and complex waste management issues. As an accredited inspection body in landfill construction, we deliver quality and safety from a single source – ensuring future-proof, legally compliant, and environmentally sound, and economically viable waste management solutions.

Our selected project examples showcase the full breadth of our expertise in action – from challenging landfill construction projects to complex remediation and waste management solutions.
