Organic Switches from Hire to McCloskey Purchase
A Cambridgeshire-based company has met the increasing demand for its recycled green waste products by purchasing a new McCloskey 628 Trommel to replace a smaller model it had previously hired.
Based at Crowland on the outskirts of Peterborough, Organic Recycling Limited (ORL) processes a variety of organic matter from green waste collected from three local authorities. The company also handles farm waste including fruit, vegetables, vegetable sludge and flowers, soil from packing plants, and excess landscaping materials. This mixed waste is diverted from landfill and converted into saleable compost.
The company originally hired trommels to sort and grade the composted material but, as it has expanded, it made financial sense for ORL to purchase its own machine. Having sampled several other makes of trommel, the McCloskey equipment came out head and shoulders above the opposition.
The decision to purchase a large trommel was taken early in 2010, but operations manager David Garford had decided to push for the larger 28 tonne McCloskey 628 machine rather than the usual 621 the company had previously hired.
Having persuaded the management that the larger machine would improve production, Garford was temporarily thwarted, finding there was an eight-week wait for what, at the time, was the first McCloskey 628 in the country.
Rather than disappoint a customer, McCloskey Equipment managing director Noel McCloskey arranged for a new demonstration 621 to be immediately installed at Crowland, whilst the 628 was in transit. The larger machine actually arrived within six weeks, and Garford reports that it was well worth the wait.
“It's a fabulous machine,” he asserts. “There are lots of clever features such as the radial conveyor, which makes stockpiling and loading so much easier. The engine compartment is a walk in space allowing easy access and maintenance on the 130 kW Cat diesel engine. It's very easy to operate and hugely popular with the staff. They actually enjoy working with the 628.”
The purchase of the McCloskey machine is part of a scheme designed to expand significantly the throughput at the ORL site. At present the site covers 4.0 hectares with a further 0.8 hectares concreted. However, plans have been submitted to expand this to 2.8 hectares and to include an anaerobic convertor. This will increase site output from the present 80,000 tonnes year to a massive 150,000 tonnes.
Raw material is stockpiled for a maximum of six months to allow decomposition to begin before it is sorted and finally screened. The material is initially processed using shredder and then a windsifter to remove materials such as paper and plastic. The compost is then restockpiled and finally passed through the McCloskey 628 trommel screener to produce a 10 and 20 mm product, whilst removing all oversized material.
“The 628 does such a good job of screening, that over 30,000 tonnes of the 10 mm product has been sold directly as a first-class compost material through our sister company, Bettaland. The compost has passed the BSI PAS 100 specification and is highly sought after,” Garford concludes. “Bettaland's customers can't get enough of it and constantly return for repeat orders. The larger end product we use as agricultural soil improver. Again it is highly prized as it is a 100 percent natural organic product. Not only are we turning a waste product into a saleable product but, thanks to McCloskey, we are also reducing the need for fertilisers, chemical additives and adding a natural product back into the soil, which is better for the environment.”
