organic refinement products
Greenview has developed a series of innovative mechanisms for processing organic material.
Greenview’s IVAS (in-vessel aeration system) operates using in-floor drainage ducts, powerful air extraction fans and a pipe network. The floor ducts transport both air and leachate to the manifold system at the bay end, from where air and leachate are separated. Air is drawn up to the fans and blown to a bio filter, while leachate flows to the ABPR dirty leachate store, usually without the need of a pump. This entire process takes place using neither complicated valves nor condensers, and can be used in both the in-vessel and maturation phases of the compost process.
MISTRAL’s forced air operation is similarly straightforward. Sucking oxygen through organic material via embedded vertical air pipes, the maturation process is hastened as air circulation increases, creating a more homogenous end product. Air is exhausted via a specifically sized bio filter containing wood matter and other particles which naturally absorb odour. With negative aeration, the maturation process is generally complete within six weeks - a far swifter transformation than the more usual twelve week cycle. MISTRAL also removes the costly need to turn windrows by machine during maturation.
Compost software
Material held in Greenview's covered bays can be any of the four grades of organic material (clean green, meat excluded food, meat included food and category 3 waste). As an ABPR requirement, raw material must be sanitised to the EU standard of 70°C for a 60 minute period to kill pathogens. To ensure this temperature is consistently reached, Greenview has developed Compost Manager, a temperature tracking and monitoring system. Using temperature probes inserted into the compost, wireless signals are sent to the central computer to track and record vessel heat levels. Once optimum heat is reached, a green light device tells the operator that sanitisation has been achieved. As part of the ABPR requirement, all data tracked up to a 24 month period is backed up to an external hard drive, accessible via the web.
Tolle Pulverisers
Developed originally by JND Technologies and found in solid waste disposal installations over the world, the GV Tolle has been adapted by Greenview to shred a range of materials including municipal solid waste (MSW), wood wastes and bulky organic material, to particle sizes of 12mm. With grinding capacities of 15-50 tonnes per hour (depending on material and machine size), the large vertical shaft feeder accepts green bin, civic amenity and catering waste without pre-sorting, and pulverises it for composting. The GV Tolle is quiet and energy efficient, processing up to 400 tonnes of material during an eight hour day.
The GV Tolle is available either as a lease option based upon tonnage processed, for a minimum five year contract, or for sale outright (finance leases can be arranged if required). For more information please contact Matt Sims on 0845 290 3610 or click here.
Bio Filters
Bio filters are our natural response to odour issues. By slowly filtering odorous air through their mix of bio material and woodchip, odour is absorbed and removed. Bio filters can be constructed swiftly and use a proven air extraction system comprising a network of pipes and large aeration fans. Odour supression systems placed around sites offer back up odour control.
Odour control
Greenview has developed an air extraction system to remove odours in waste transfer storage. Air is drawn via fan through pipes at the bay rear and exhausted through a bio filter contained within the bottom void of the building wall AlfaBlocs. An irrigation line to keep the bio filter moist (maintaining its ability to absorb odour) similarly runs through the AlfaBloc wall system.
