Waste

We are constantly considering how we can avoid or reduce waste. Oil and oleaginous materials, waste which contains metal and gas cylinders which have reached the end of their useful life are our most common waste products. By using closed-loop systems for products, we increase both material efficiency and resource efficiency and cut the volume of waste produced. One example is lime slurry, a by-product of acetylene production, which can be used in other industries without any treatment being required.

We dispose of any waste which cannot be recycled in an environmentally sound manner. We comply with local regulations and classify our waste as hazardous and non-hazardous in accordance with relevant legislation in the country in which we are operating. The amount of waste at different sites depends on the type of business operations being carried out there. Therefore, our waste management objectives are based on regional requirements. The measures we adopt focus in particular on hazardous waste.

Around 85 percent of the waste classified as hazardous is generated at a small number of locations around the world. Examples of plants producing such waste are a synthesis gas production plant and a number of acetylene plants where hazardous waste is generated as a result of the disposal of acetylene cylinders. In all the locations where hazardous waste is produced, there are programmes to deal with the waste in accordance with regional requirements and to continue to reduce this waste.

When making a multi-year comparison of the volume of waste produced, there can be significant fluctuations, as the volume of waste is dependent on the extent of our construction operations. The overall amount of waste fell in 2017 compared with 2016, as less hazardous waste was produced.

In line with the information in the Financial Report 2017, the figures provided for the years 2015, 2016 and 2017 exclude the business of the logistics service provider Gist, as it has been reported as a discontinued operation.

The amount of waste for single sites depends on the different type of business and is partly based on proven estimation methods. Due to the change of estimate for one specific business area the numbers for waste for 2016 have been adjusted for better comparability with 2017 figures.

Incineration waste is partly used for heat recovery.

We offer our customers numerous solutions to help them avoid or recycle waste. In the United States, we have also been involved since 2009 in a joint venture with a Californian waste service provider to extract fuel and energy from waste for around 8,500 households. Around 2.3 million tonnes of waste is recycled annually and used – about 36 times as much as the amount of waste generated by our entire gases production in 2017.
