A few words about steel – a life cycle of green performance Lindab’s steel rainwater system has proved itself to be the most environmentally friendly material available, with a natural place in today’s approach to green sustainability. A study on the life cycle assessment of rainwater products in different materials has compared the environmental impact of products, processes and disposal of seven different materials, covering their entire life cycle from cradle-to-grave. This study covers materials frequently used in rainwater products such as aluminium, zinc, copper, cast iron, galvanised steel and plastic. This life cycle comparison includes the steps taken up until a product leaves the factory gate; extraction of raw materials, production, energy used, including transport, plus disposal, recycling or waste treatment after use. The environmental impact of all seven materials clearly shows that Lindab’s steel, in a product life cycle study, has the lowest carbon footprint of any of its competitors.

The carbon footprint of steel Lindab’s steel has the lowest carbon footprint of any rainwater system, with up to 30% manufactured from recycled material, which is itself completely recyclable. The case for Lindab’s steel is further proven with its long-life durability. The useful life of a component is of vital importance; the longer the lifetime, the fewer components need to be produced, making the environmental impact even less.

Product life cycle CO2 impact Increasingly customers are asking for the carbon footprint of products, in order to determine how far they contribute to climate change. The Lindab steel product life cycle CO2 study has highlighted how current CO2 levels are 30% higher than in the pre-industrial era and how a doubling of levels in the atmosphere is expected to occur over the next century. The impact and implications of such changes are far-reaching. It is with this in mind that Lindab strives to minimise the environmental impact caused by the company’s operations and products; this environmental commitment means that products are developed based upon a life cycle perspective, with set targets for continual improvements.
