A new online Recycled Aggregate Supplier Directory has been launched by Zero Waste Scotland which aims to showcase best practice and instil confidence in buyers of recycled aggregate.
Crushing and screening waste concrete, brick, and asphalt from construction and demolition to produce recycled aggregates is standard practice in Scotland. It avoids sending waste to landfill sites and reduces the environmental impacts resulting from the extraction of natural aggregates.
However, quality recycled aggregates which meet WRAP's aggregates Quality Protocol will conform to British Standards and Specifications in the same way as natural aggregates, and importantly, they will have ceased to be waste. Recycled aggregates not produced to such a quality management system will remain waste, have uncertain performance and remain subject to waste management regulations.
Zero Waste Scotland's new Directory lists recycled aggregate producers which operate to the aggregates Quality Protocol, providing their customers with confidence that the company can produce quality products.
In addition, all suppliers on the directory have been independently inspected and assessed by TRL (Transport Research Laboratory), and are subject to regular reviews by Zero Waste Scotland to demonstrate their compliance with the requirements.
Iain Gulland, Director, Zero Waste Scotland said:
"The progress made by Scotland's construction industry to increase re-use and recycling is commendable. In 2010, it is estimated that the industry produced six million tonnes of waste, and that around 80% was recycled.
"Recycled aggregates are a major contributor to this total, providing savings to the industry on both disposal costs and aggregate procurement. However, it is essential that the quality of aggregate being produced and sold to customers meets industry specifications and its use complies with waste management regulations.
"This directory has been developed to ensure buyers of aggregate can feel confident about the quality of material they buy, and to promote recycling services which are available to the construction industry."
Lianne Rafferty, Environmental Manager (Construction), Graham Construction said:
"It's brilliant to see this new directory, which will be a great tool to support the development of a more reputable recycled aggregates industry. Having confirmation that the recycled aggregate has ceased to be waste removes the uncertainty of handling and using materials which could still be subject to waste management legislation.
"As a user of recycled aggregates, the directory allows us to understand the options available, and make informed, safe choices based on this. I hope that suppliers will get behind the directory and help to eliminate the lack of confidence in the industry that exists at present."
John Doyle, Area Recycling Manager, Tarmac said:
"The Recycled Aggregate Supplier Directory is a welcome new tool, and we as a major national company are delighted to be involved in it from a very early stage.
"Having a well-regulated and managed supply chain allows us to enhance our reputation as a responsible and reliable supplier of recycled aggregate, which sends a clear and concise message to clients that we are dependable supplier.
"The recycled aggregate market is one key way in which we can minimise impact and divert waste from landfill, helping us as a supplier to contribute to a more sustainable construction industry in Scotland."
Andy Sullivan, Senior Policy Officer, SEPA said:
"This great new tool will offer clients and contractors reassurance that the site they have chosen is capable of producing the right quality of recycled aggregates. We need to recycle more and more of our waste and hopefully this Directory will increase the demand for recycled aggregate, getting us above the 80% we managed in 2010.
"A listing in a Directory like this is an excellent way of proving to your customers that you take your environmental responsibilities seriously, so if you are a company producing recycled aggregate and you can demonstrate your commitment to the environment, do contact Zero Waste Scotland and look at being added to this resource."
