Deerdykes is a Composting and Organics Recycling Facility In-Vessel Project, actively receiving green waste, liquid wastes (industrial effluents) and sludges (from industrial wastes) for on-site processing. Green waste is delivered in large waste collection vehicles and is offloaded into a reception area. It is shredded and composted in extended beds on hard-standing areas. Liquid waste is delivered to site in tankers and off-loaded into one of the storage tanks below the sludge house. Liquid waste is stored prior to being discharged to sewer. Sludges are processed through a dewaterer in the mixing building.


    Location: Cumbernauld, United Kingdom
    Region: Europe-Africa
    Market Sector: Water & Wastewater
    Status: Complete
    The liquid fraction after pressing is discharged to sewer and the cake is mixed with the shredded green waste and co-composted in the Invessel compositing tunnels. The function of the tunnels is to stabilize green waste, stabilize sludge cake or animal by-products, to reduce odor generation during composting. During stabilization in the tunnels air is passed through the shredded green waste and sludge mix in a controlled manner. Air that passes through the material is either re-circulated or sent to the wet scrubber and bio-filter for treatment. Air is supplied to the tunnels using blowers and air distribution networks are cast into the tunnel bases, supplying fresh and re-circulated air to compost the material. When composted the material is removed using a wheeled loader as is placed into a maturation area before being screened to the required sizes and stored until dispatch as a high value commercial product. This is a new market entry for MWH into Solid Waste. In-vessel composting is fairly new in terms of solid waste with only a few plants built throughout the U.K., but with a growing trend towards more solid waste process this market is expanding rapidly.
    The in-vessel composting process is only the beginning of the development of the Deerdykes site, with materials handling improvements planned and an Aerobic Digestion Plant also being proposed.
