What are the Differences Between Quarried & Recycled Aggregates?

Here at B&A Group, we supply a wide range of premium quarried and recycled aggregates to clients across the South West. A common query we receive from our clients is what are the differences between recycled and quarried aggregate. In this article, we give an overview of the differences between the two and what you can expect from our excellent aggregate products. 

For quality quarried and recycled aggregates in Bristol and the South West, contact B&A Group on 0117 982 9561 or email info@bristolandavon.co.uk.

Primary Aggregates

Aggregates can be divided into two categories. The first is primary aggregates. These come from naturally occurring mineral deposits, extracted and used for the first time as aggregates. Some are mined from the land and others are ‘marine dredged’. Common examples are limestone, sandstone and igneous rock. Quarried aggregates are primary aggregates.

Secondary Aggregates

The second category is secondary aggregates. These aggregates come as a byproduct of other industrial operations or quarrying processes. For example, through the demolition of buildings or other structures, road planings or railway track ballast. Recycled aggregates are secondary aggregates.

While quarried aggregate is taken straight from the ground for crushing and mixing, recycled aggregates must first go through a decontamination and screening process to ensure they meet strict legal standards. First, any contaminants such as wood, plastic or metal are removed. The aggregate is then crushed and carefully screened before it can be reused. 

Each year, the UK uses around 200 million tonnes of aggregate. Approximately ¼ of this is recycled material. Recycled aggregate is becoming a popular choice within the construction industry. As companies strive to meet environmental commitments, many have sought to use sustainable materials. Recycled aggregates help divert construction waste from landfill and have less of an impact on the environment than mining. Once it becomes aggregate, it is no longer classed as waste.

Not only is it a sustainable means of obtaining materials, but it can also be extremely cost effective. Recycled aggregates offer the same high quality as quarried aggregates. As they can be locally produced, transport costs are often cheaper. Recycled aggregates are incredibly versatile and are just as strong and durable as quarried aggregates. 

Over recent years, there has been a vast improvement in the standard and quality of recycled aggregates.
