Waste

Waste

The main waste products of our Group are oil and oleaginous materials, waste which contains metal and gas cylinders which have reached the end of their useful life. By using closed-loop systems for products, we increase our material efficiency and resource efficiency and cut the quantity of waste produced. Lime slurry, for example, a by-product of acetylene production, can be re-used in other industries without any further treatment being required. We dispose of any waste which is not suitable for re-use or recycling in an environmentally sound manner. Thereby, we classify our waste as hazardous or non-hazardous in accordance with the relevant legislation in the country in which we are operating. When devising measures to achieve further reductions in waste, we focus in particular on hazardous waste. The overall amount of waste fell in 2015 compared with 2014, as less waste was produced on construction sites.

The lower figure for waste in 2015 is mainly due to a reduction in construction waste.

Incineration waste is partly used for heat recovery.

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.

Our 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. In the reporting year, we achieved the target we had set ourselves of increasing the waste recycling rate in the UK to 70 percent by 2015. By the end of 2015, a 71 percent recycling rate for waste was achieved in the region. Across the Group, the recycling rate was around 43 percent. During the reporting year, as part of a national campaign in New Zealand, we expanded our activities relating to the proper disposal of environmentally harmful refrigerants such as chlorofluorocarbons (CFCs), which are used for example in old refrigeration and air conditioning units. Working together with other companies, we offer free collection and disposal to both customers and non-customers. Since the beginning of the campaign in 1993, more than 290 tonnes of refrigerants have been collected. This is equivalent to a reduction in CO2 emissions of up to 260,000 tonnes. Since 2009, we have been involved in a joint venture with a Californian waste service provider in the US to extract fuel and energy from waste. Around 2.3 million tonnes of waste is recycled annually, which is sufficient to provide liquefied biogas to power 300 refuse vehicles. Additionally, the waste service provider's site provides electricity for around 8,500 households in the region.
