We care for the environment and are glad to see our hard work is paying off.

A Strong Performance

We give new life to used materials. This helps to protect the world’s limited resources and preserve the planet for future generations. Our work puts us at the heart of the circular economy.

At Renewi, protecting and preserving the environment is extremely important and we take that responsibility seriously. That is why we are delighted that our hard work is showing through in our CSR performance figures for 2016/17.

Of the 15 million tonnes of waste our sites handled, 90% was recycled as secondary raw materials or recovered for use in energy production. Through those recycling and recovery activities, we prevented more than three million tonnes of carbon being released into the atmosphere and we produced more than 172 billion watt hours of green electricity – enough to supply 40,000 homes.

Carbon prevention is a core part of our mission. As part of our commitment to this goal, in October 2016 we signed up to the Sustainable Mobility Pledge, a Dutch initiative to reduce the carbon emissions generated by employees travelling to and from work. Although it has a small effect, it underpins our commitment in this area.

We also continued to support Ocean Cleanup – a project that is testing an innovative cleaning system designed to drastically reduce the eight million tonnes of plastic waste that enters our oceans every year. You can read more about our involvement in these environmental initiatives on pages 19 and 20 of our Corporate Social Responsibility Report.

Next year’s goals

In 2017/18, we are challenging ourselves to build on this year’s impressive figures by working towards a 95% recycling and recovery rate, a 10% increase in carbon prevention and a 60% increase in green electricity production – all by 2020.

We will also push ourselves in the area of energy efficiency. Producing energy from waste is just one part of the equation; using energy efficiently to power our operations is equally important. In the coming months, we will be working to define what energy efficiency means for our combined Group and establishing how we collect and analyse data on this important area. In 2018/19, we hope to have a clearly defined objective to work towards.

Total waste handled at sites (million tonnes) 14.28 14.78
Amount of materials recycled (million tonnes)1 9.69 10.25
Amount of materials recovered for energy production from waste (million tonnes)2 3.16 3.07
Total materials recycled and recovered for energy production (million tonnes) 12.85 13.31
Recycling as % of total waste handled 68% 69%
Recycling and recovery as % of total waste handled 90% 90%

1Recycling is materials given a ‘second life’ for reprocessing into new goods/materials; recovery is waste used for energy
2Includes water recovery and moisture loss during treatment for some technologies employed
