For the manufacturing process we do not directly use coal, oil or gas. We use electricity for production purposes and gas for heating the work area. We use 5,358,616kWh of electricity per year and 3,360,066kWh of gas (source data from energy bills)
With regards to climate change and greenhouse gasses the above energy consumption is equivalent to 3525 tonnes of carbon dioxide. Calculated using the “Cities for Climate Protection Greenhouse Gas” software.
Producing a tonne of crude steel is equivalent to 1.9 tonnes of CO2 (world average from the World Steel Association website). Using the above data to convert this to rolled section would take an additional 0.04 tonnes of CO2. Total for rolled section including steel production is 1.94 tonnes of CO2.
The manufacture of steel allows for 100% re-used materials to be added. Tata Steel Europe Limited 2014 website under Sustainability FAQs states “Waste Resource Action Programme (WRAP) recommends applying a value of 60% recycled content for structural steel sourced in the UK”
100% of the steel sections can be recycled at the end of use or life. Source Data – Worldsteel Association Fact Sheet – Steel and Raw Materials Last updated: CB, HR, VR, June 2016
The durability of cold formed steel is dependent upon the environmental conditions it is exposed to and the coating type and thickness of the product supplied. These need to be taken into account when selecting a product and it’s required life to first maintenance.
In its finished state, of a steel section, there is no potential for contamination, this will only occur if the product state is changed and this is not foreseen.
