Environmental Considerations

SAS systems are manufactured from steel and aluminium components. Construction using these metals is dry, dust-free and has excellent low waste credentials throughout a building’s life cycle.

Value of Steel

Steel is a remarkable material not only for its inherent structural properties. It is the world’s most recycled metal and can be recycled indefinitely, making it a near perfect sustainable material. Recycling steel does not compromise its quality nor performance characteristics. New steel produced from reclaimed and recycled steel can therefore be used in the manufacturing of any steel product.

Steel scrap is an essential part of the production process of new steel products. Recycled content can account for up to 60% of the raw material used. Steel’s magnetic properties make it the easiest material to recover from industrial waste. As a result, there is a genuine demand for recovered steel, which allows the recycling loop to be closed. Every steel plant is potentially a recycling plant.

Other metal advantages include no associated landfill costs and significant residual value at end of life. The rising costs of landfill taxes provide obvious reasons to specify steel. Specifying metal reaps considerable long term gains in both life cycle and environmental costs.

Global recycling infrastructures

The infrastructure for scrap recycling is well established globally. In Europe 60% of steel production is made from scrap, globally it is 40%. The current recycling and re-use rate for steel construction products in the UK is 94%, and all new steel has a recycled content.

Recycling benefits

Every tonne of steel recycled makes the following environmental saving:

  • 1.5 tonnes of iron ore
  • 0.5 tonnes of coal
  • 40% of the water required in production
  • 75% of the energy needed to make steel from virgin material
  • 1.28 tonnes of solid waste
  • Reduction of air emission by 86%
  • Reduction of water pollution by 76%


Our approach to waste reduction

Reducing waste is not just about recycling site waste. The key is to formulate strategies to stop producing it in the first place.

At SAS International the metal and aluminium used in manufacturing our systems contains varying percentages of recycled content and is in itself fully recyclable.

Working with the project team, including client requirements, SAS are able to develop and adopt best practice for the project. This can include establishing a sustainable logistics procedure re-utilising delivery packaging or designing and pre-forming apertures for lighting and other services are during manufacturing with any wastage recycled, this in turn reduces on site wastage.

Factory finished metal products installed in accordance with our recommendations provide a durable product. Given appropriate use and maintenance, SAS systems can be expected to remain serviceable for a minimum of 25 years.
