Energy use

A Parc tower is very energy efficient, it only uses power when needed by the composting process, we add no heat to the tower, we recycle any water used and process the tower atmosphere through bio-filters.


Site Power Supply

A four tower site capable of treating ninety thousand tonnes per annum will require a three phase 400 volt supply rated at 1000KVA for the entire facility including waste reception, welfare facilities, office, workshop and floodlighting. The total power consumption at the current operational two tower plant at Thornley ranges from 36 to 45Kwh per tonne processed, for the entire facility. This consumption includes all digester operations,workshops, weighbridge, offices, amenity block and all heating and
lighting.

 

Site area

An appropriate site would typically have a minimum area of 16,250m2 to accommodate the building, weighbridge, turning areas and limited parking but ideally an area of 20,000m2 (two hectares) to allow for collection vehicle parking and other connected infrastructure and offices.
A four tower plant would typically have maximum building dimensions of 116m long, 70m wide and 20m high with a floor area of around 6,400m2. The building would comprise a reception hall with a maximum floor area of 3,150m2 with an incoming waste capacity of up to five thousand tonnes, depending upon internal push wall heights, which would also function as a regional transfer station. Should the transfer station function not be required the reception area could be reduced significantly. The reception hall will
also house the shredder and the first section of the conveyor leading to the main Hall.

The main Hall housing the four towers would typically have a floor area of 2,046m2 and be the highest section of the building.

The current Thornley Parc plant has the segregation stage co-located with the digester towers. Depending upon regional requirements it may make more economic and environmental sense to centralize segregation facilities, however should an on-site segregation system be appropriate it would require a typical floor area 1,200m2 and be around 9m high.
