Raw materials

Efficient use of resources enables us to reduce our environmental impact and cut costs. The most important raw material we use in the production of our gases is air. More than 80 percent of the weight of gases sold by Linde in 2015 was derived from this renewable resource. In the case of carbon dioxide, another of the Group’s main products, around 80 percent of the raw material required is recovered from recycling processes. Another major raw material we use is natural gas. This is used principally in hydrogen plants. In addition, key materials processed include steel and aluminium, required for example for the manufacture of components used in plant construction. In order to manufacture products, energy is needed as fuel.

Our key packaging material is gas cylinders. In general, these are re-used. A typical Linde cylinder has a lifespan of many years and is refilled on average four times a year. Currently, there are around 25 million Linde cylinders in circulation. We examine our supply chain for conflict minerals listed in the US Dodd-Frank Act. Against this background, for example, all Linde Electronics suppliers are required to confirm that their products are conflict-free. We check that this is indeed the case when conducting our regular supplier audits.

As a result of the application of the revised accounting standards, the sites in the scope of our reporting changed in the 2013 financial year. Accordingly, the key financial, environmental and employee KPIs for 2012 were adjusted retrospectively. In addition, the KPIs for employees, occupational health and safety and environmental protection for the year 2012 were retrospectively adjusted to account for the effects of the acquisition of the US homecare company Lincare.

Renewable raw materials

Our technologies underpin the use of renewable energy and renewable raw materials. For example, we are participating in a pilot project launched in 2015 in Mainz, Germany. In what is currently the largest electrolysis plant in the world, surplus renewable energy, especially wind power, is being converted into hydrogen. In Scandinavia, our customers have been able to purchase hydrogen produced entirely from renewable energy such as wind power since 2014 which is certified with a guarantee of origin.
