  • Feasibility of anaerobic membrane bioreactors (AnMBR) for onsite sanitation and resource recovery (nutrients, energy and water) in urban slums

    Slums are challenging locations for sanitation technologies. High population densities, a lack of water and electricity infrastructure, and space constraints combine to ensure that many traditional waste treatment technologies fail when implemented in this context. This paper proposes the use of anaerobic membrane bioreactors (AnMBRs) for slum sanitation. AnMBRs allow for localized water ...

  • Plasterboard waste recovery from smaller building sites

    Most methods for recovering waste plasterboard from construction sites rely on it being segregated on site into adedicated collection container, such as a skip, bin or bags.  This can be difficult for smaller building sites where spacefor these containers may be limited, and the quantities of plasterboard waste are small thus reducing the costeffectiveness of recovery. However, many small ...

  • Organics recovery expands in Wyoming`s tetons

    THE TOWN of Jackson, Wyoming is located in a glacial valley, originally referred to as Jackson's Hole by the fur trappers and game hunters who came down out of the mountains to rendezvous and sell their goods for shipment to markets back east. Today, elk and bison spend winter on the National Elk Refuge, its fence line abutting the town of Jackson, where they are fed and protected until they ...
