Waste

We aim to avoid the creation of waste as much as possible or to reduce waste. In 2014, Linde generated around 94,100 tonnes of waste (2013: 124,900 tonnes). The decrease in the amount of waste generated was due above all to a reduction in construction waste. Our main waste products are oil and oleaginous materials, chemicals, waste which contains metal, and gas cylinders which have reached the end of their useful life. Closed-loop systems for products help us to increase both our material efficiency and resource efficiency and to cut the volume of waste produced. Lime slurry, for example, a by-product of acetylene production, can be reused in other industries without any further treatment being required.

Most of the waste generated is utilised. We dispose of any waste which is not suitable for re-use or recycling in an environmentally sound manner and in accordance with local regulations. We classify waste as hazardous or non-hazardous in accordance with the relevant legislation in the country in which we are operating. We are focusing in particular on achieving further reductions in hazardous waste. In 2014, we launched an initiative designed to record gas cylinders stored worldwide which require special means of disposal. The aim is to ensure the disposal of these cylinders in the most efficient and environmentally friendly way possible.

The lower figure for waste in 2014 is mainly due to a reduction in construction waste.

Incineration waste is partly used for heat recovery.

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.

Our other waste management objectives are based on regional requirements, as the type of waste produced differs greatly from one site to another depending on the processes being carried out. During the reporting year, we achieved the regional target we had set ourselves of increasing our waste recycling rate in the UK to 65 percent by 2014. As a result, we have raised and extended our target. By the end of 2015, our aim is to achieve a 70 percent recycling rate for waste in this region. Since 2009, we have been involved in a joint venture with a Californian waste service provider to extract biogas from waste. Around 2.3 million tonnes of waste is recycled annually in this way, which is sufficient to power 300 refuse collection vehicles and provide electricity for around 8,500 households in the region.

We are currently analysing the results of a pilot waste management project in the South & East Asia region in order to develop measures we can apply across the regions to reduce both the costs and environmental impact of waste. We are also constantly working on cutting waste still further in the Healthcare product area: for example, by reducing the proportion of electrical waste generated by medical devices.
