Description

Environmentally Friendly

Proven itself to be the most environmentally friendly material available, Lindab’s steel rainwater system has earned a natural place in today’s approach to green sustainability.

A product life cycle study of seven materials for rainwater products has shown Lindab’s steel has the lowest carbon footprint of any of its competitors. The materials included in the study were aluminium, zinc, copper, cast iron, plastic and galvanised steel. The study compared the entire life cycle from cradle-to-grave, the environmental impact of products, processes and the disposal of these seven different materials.

Included in the life cycle comparison were:

  • ​Steps taken up until a product leaves the factory gate 
  • Extraction of raw materials
  • Production
  • Energy used
  • Transport
  • Disposal
  • Recycling or waste treatment after use

Comparison of the carbon impact of a functional unit of 1m downpipe, in all seven different materials, from cradle-to-grave.

The Carbon Footprint of Steel

With up to 30% manufactured from recycled material, which itself is completely recyclable, Lindab’s steel has the lowest carbon footprint of any Rainwater System. Strong, durable and made to last Lindab’s steel for their Rainwater System has a longer lifetime making the environmental impact even less due to the fact fewer components need to be produced.​
