Resource Management Strategies & Technologies

Today, virtually all governmental and commercial activity within the energy and environmental marketplaces takes place at the intersection of technology, economics and public policy. Within that specialized and demanding business environment, CommonWealth’s ability to add or create value for its clients and partners rests in large measure on its knowledge of the technical and economic performance characteristics — and the regulatory requirements and constraints — of a wide range of resource management and utilization strategies and related technologies. As consultants and developers, CommonWealth’s expertise covers a broad range of technologies associated with the following strategies for materials and waste management, resource recovery, renewable energy/distributed generation and environmental impact mitigation:

Materials and Waste Management

  • • Municipal solid waste (MSW) collection strategies:
    • — Manual and automated collection
    • — Co-collection of MSW and recyclables
    • — Source separation and collection strategies
  • • Waste transfer systems and strategies:
    • — Inter-modal transfer
    • — Transfer w/ and w/o intermediate handling
    • — Short haul/long-haul/rail-haul transfer strategies
  • • Landfill disposal strategies:
    • — MSW landfill disposal
    • — Ash monofill disposal
    • — Co-disposal of MSW and sludge
    • — C&D landfill disposal
