Weighing Up Aggregate Returns for Recycling Centre

An Avery Weigh-Tronix weighbridge/truck scale system is at the heart of an aggregate recycling scheme that can save construction companies up to £20/$35 per tonne disposal costs. The scheme run by Inverness (Scotland) based Highland Recycling also has twin benefits for the environment: it avoids landfill and reduces reliance on primary aggregates.

Says Rennie Spence, business development manager for Highland Recycling: “Our business takes all of the hassle and most of the cost out of waste aggregate disposal for companies. We collect waste material from a variety of sources and then rework it before selling the recycled material for £10 to £11 per tonne.”

Data at the heart of the operation

“To make the business work we must collect accurate data about the weight of the waste  aggregate, what it is, who the customer is and then finally the weight of the recycled material produced. We also need to provide accurate quarterly returns to the Scottish Environmental Protection Agency (SEPA).“

The company approached Avery Weigh-Tronix to design and install a weighbridge system. The resulting 15m x 3m Bridgemont weighbridge weighs the material coming into and leaving the site on wagons and stores the information on the software. Highland Recycling can then print an invoice with the weighbridge ticket or, for contract customers, they can store the information and then invoice them at the end of the month.

Reliable service provider for increased uptime

Continues Spence: “The weighbridge system really is at the heart of our business. It allows us to not only collect data but also to analyse our efficiency. As a critical part of the business, the weighbridge must remain operational so that the site can continue to generate revenue. For this reason we have also signed a service contract with Avery Weigh-Tronix.”

This maintenance and service contract covers all parts and labour for normal wear and tear, unlimited callouts with an eight-hour response time, technical advice and software support.

Says Paul McIntyre, operations buyer for Highland Quality Construction, parent company of Highland Recycling: “We were looking at ways to minimise the amount of aggregates that were being dumped in landfills across Northern Scotland. We made a decision to recycle as much of these products as possible.

“Not only does this help demonstrate our environmental credentials as a supplier, but with the collection and reporting of accurate weight data, we have now established a successful and  profitable recycling business in its own right.”

Recycled aggregate is in high demand, with the Waste and Resources Action Programme (WRAP) forecasting that it will fulfil 20% of the total aggregates market in Scotland by 2012.
