Sustainability and Recycling
With increasing pressure on landfill capacity and the ongoing requirement for the construction industry to divert waste away from landfills to meet UK regulations and sustainability targets, CTS’s recycled aggregate test services can support by helping to classify materials as a product rather than waste.
Following the use of our aggregate test service, using recycled aggregates, not only significantly reduces the cost of sending unwanted materials to landfill, but also supports Environmental Social Governance (ESG/CSR) initiatives by helping to reduce construction waste and protect the environment.
Why Choose CTS for Aggregate Test Services?
CTS is recognised as one of the UKs leading testing laboratories, with substantial experience in aggregate test services gained through decades of participation in major construction and civil engineering projects.
Our project and contract managers ensure efficient communication throughout every project and ensure maximum data acquisition whilst minimising costs.
Frequently Asked Questions
What are recycled aggregate materials?
Recycled materials are inert waste aggregate derived from crushed concrete, crushed bricks, masonry, bituminous materials, municipal incinerator bottom ash, air-cooled blast furnace slag, basic oxygen furnace slag, and electric arc furnace slag.
How is recycled aggregate made?
Recycled aggregate is generally made from the reprocessing of inert materials, which involves activities such as crushing, mixing, or grading aggregate in accordance with the relevant British Standard and WRAP Protocol
What is recycled concrete aggregate used for?
There are a number of end uses for recycled concrete aggregate conforming to British Standards and Specification for Highway Works
Is recycled aggregate cheaper?
Yes, it is less expensive to produce, reduces materials sent to landfills and incurring landfill tax, and reduces the amount of virgin material produced, therefore lessening the use of natural resources.
