Waste

We work continuously to reduce and avoid waste. Linde’s main waste products are oil and oleaginous materials, chemicals, waste-containing metal, and gas cylinders that have reached the end of their useful life. Closed-loop systems for products help to increase material and resource efficiency and to cut the volume of waste produced. Lime slurry, for example, a by-product of acetylene production, can be used in other industries without further treatment. Waste that cannot be recycled is disposed of in an environmentally sound manner in compliance with local regulations.

We classify waste as hazardous or non-hazardous in line with national legislation. The increased amount of waste in 2013 compared to 2012 is due to the impact of several major construction projects in the Gases Division.

As a result of the first-time 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. To ensure that the figures for 2012 and 2013 can be compared, we reported the full year 2012 for Lincare.

Our waste management targets are determined by regional requirements, as the type of waste produced differs significantly from one site to another depending on the diverse business activities. In the UK, for instance, we have set ourselves a regional target of increasing the waste recycling rate to 65 percent by 2014, having already achieved 60 percent in the year under review. We launched a pilot project in South-East Asia in 2013 to optimise waste management. The aim was to reduce both costs and environmental impact. The results will form the basis for the development of further waste management measures in other regions. In Africa, we developed a new recycling programme in 2013. The breathing bags produced by the regional subsidiary Afrox and used by mine workers have to be replaced every ten years. Afrox took back thousands of these breathing sets and recycled some of them into products such as bags and aprons.
