Northern Star turns Blue

Highlands based Pat Munro Ltd have recently installed a recycling system from equipment manufacturers BlueMAC to revolutionize the waste side of their business.

Established in 1945 with a predominantly quarrying background, the company have evolved over the years to become a multi-disciplined organisation which specialises in quarrying, civils, construction, haulage and waste. Over the years, Pat Munro has naturally progressed into other markets which have synergy with their primary aggregate business. In the late 1990’s , the company started off in the waste sector and have developed this arm of the business to its current levels, processing over 60,000tpa. Around this time, the landfill opportunities in the Highlands were no longer available, meaning increased recycling onsite and a long haul of landfill materials down to the central belt. With increasing environmental legislations within Scotland on carbon footprint and zero waste, Pat Munro Ltd decided to radically change their approach to their waste business.

As a result, the new state of the art MRF facility from BlueMAC has been installed to enable the company to dramatically improve their recovery rates whilst greatly reducing the detrimental haulage factor. Commenting on the strategy of the new MRF, PM Waste Manager, Veronica Symonds, added “In our new MRF facility, we feel that we are able to revolutionise the waste sector in the Highlands. The plant has a future proofed design, enabling us to process greatly increased volumes going forward. Whilst this new facility will give us a real commercial advantage in the local market, we intend to engage with the other waste services providers, in the area, with a view to working together to provide the best, and most cost-effective, waste solutions for the Highland area.”

The new plant consists of a 6m feeder with incline belt taking the material to a BlueMAC 25-70 trommel. The robust trommel with maintenance friendly design is 7m long with a 2.5m drum. From the trommel, 40mm minus fine material is removed to reduce the volume of the waste stream and make for easier sorting. The oversize material then travels from the trommel to a 90 degree change of direction at which point the material passes an air separator which removes the light fractions. The remaining oversize material then enters the sorting cabin with its 5 double sided bays for the safe removal of recyclables. For operatives safety, the cabin is fitted with industrial standard fittings such as lighting, heaters, windows and emergency stop cords. Once all recyclables have been removed the remaining waste passes a magnet for the safe removal of ferrous metals prior to the left over hard core to be stockpiled in the end bay.

Further commenting on the new installation Veronica Symonds said “We are delighted with the installation of our new plant, the BlueMAC team have been first class from concept through to turning the system on. The initial performance has been excellent and we look forward to developing our business on the back of this new facility”
