Problem Addressed

Carbon emissions reduction and enhancement of a more circular economy. 

Solution Overview

With over 45 years history of supplying surplus steel to the construction sector, Cleveland Steel & Tubes (CST) promote the concept of the ‘Greener Steel’ and the circular economy. Their inventory is comprised of steel tubes recovered predominantly from steel mills and the oil and gas industry. For the most part, the pipes are surplus stock that is produced to a high standard – but never actually used in the project. CST source this product worldwide, store it at a 100-acre facility in North Yorkshire, UK and then supply it to customers worldwide. 

Life Cycle Assessment commissioned by CST found that the greenhouse gas emissions savings were as high as 96% when using surplus steel compared to buying brand new steel. The life cycle analysis considered a comprehensive range of factors, including material processing, logistics, and disposal of any generated waste. The reuse of steel provided by CST aligns its business model with the key principles of the circular economy. Repurposing steel provides a substantial reduction in the carbon footprint of a core building material – which can help construction contractors to meet their sustainability obligations and it can be incorporated within a BREEAM assessment. 

Case Study

High profile structures that contain steel supplied by CST include; the Olympic stadium in London (where 500T of carbon was saved), the roof of Wimbledon Court No. 1, Canary Wharf, wind turbines, marina developments and the London Eye. A strong export customer base has purchased pipes for projects as far afield as Australia and Hong Kong.
