Ellington MBT Fines Plant
The IVC composting plant in Ellington Northumberland is the latest plant in the CRS portfolio. As turnkey contractors, CRS are project managing the construction of the plant for SITA. The plant is designed to receive 40,000 t/a of MBT fines from the Byker recycling plant. Ground work began on the site in March 2005 and already the maturation building and composting tunnels structures are erected.
Pre-shredded and screened MBT fines will be delivered to the Elllington plant where they will undergo the CRS Hydrum treatment to produce a homogenous, moist material that is suitable for composting. Two banks of 10 CRS Drive-through Tunnels will be used to process the waste. The tunnels will be loaded using an automatic feed system. The facility will be ABPR compliant with the full temperature monitoring, air management and odour control. After degradation and passing the ABPR parameters of 60°C for 2 days twice, the processed waste is moved to a covered maturation building where it will be windrow turned and bio-dried. The compost-like output (CLO) produced will then under go CRS' unique G2S post composting treatment to produce a sharps free soil forming material. The G2S treatment comprises screening the compost at 4 mm, milling the oversize to reduce the glass to sand and a second screening to remove all plastics and other contaminants. The two sub-4 mm fractions are then combined to produce a biostabilised CLO suitable for above ground land restoration.
