Waste

We are constantly looking for ways to reduce and avoid waste. Our first priority is to recycle. If this is not possible, we dispose of waste in line with environmental regulations. In 2011, we organised a regional review of waste types in order to assess potential waste management targets.

Waste from our business operations mainly consists of oils and oil-contaminated materials, chemicals, and metallic waste, or gas cylinders. As a general rule, gas cylinders are fully recyclable at the end of their useful life. Only a few types need to be disposed of at landfill sites. We classify the waste generated by our business activities as hazardous or non-hazardous in line with national legislation. Hazardous waste at Linde primarily consists of oil and oil-contaminated materials from compressors in our air separation, acetylene and hydrogen plants as well as oil-contaminated sludge generated when oil/water separators are cleaned.

Our commitment to responsible waste management extends to working with our customers and business partners. For instance, we offer a waste collection and environmentally sound disposal service to some of our customers. In addition, compared with conventional processes, industrial gases can help to lower emissions and energy consumption during recycling. This is particularly true for materials such as aluminium and rubber.

In California, we are collaborating with leading recycling and waste disposal company Waste Management to simplify waste streams and reduce costs. The two companies intend to capitalise on the opportunities presented by improved waste recycling. In a joint venture, Linde and Waste Management have also developed a process that uses gas from compostable waste to manufacture fuel for the company’s waste disposal trucks.
