Zero Waste with DS Smith
3–7 September 2018 is Zero Waste Week, an annual awareness campaign for reducing landfill, increasing reuse and recycling, and helping to protect the environment. For Zero Waste Week, we’re exploring what zero waste is and what it means to DS Smith.
What is zero waste?
‘Zero waste’ is the idea that by making changes to the way we live, work, and use resources, we could eliminate all unnecessary waste from society. If all products could be designed so that they produce no waste by making all of their components reusable or recyclable, and if all people had access to reliable recycling services, we might be able to create a society where items will always be reused or recycled instead of being thrown away.
It’s a hugely ambitious idea, and one that will take some time for society to achieve, because many of our products and processes currently create waste in one way or another. But the principles of zero waste can be adopted now to help us achieve those zero waste ambitions. By preventing items from becoming waste, and designing for reuse and recyclability, people can reduce the amount of waste that they generate.
Our ‘Box to Box in 14 Days ’ model, with its closed paper recycling loop, is part of the zero waste philosophy. By recycling used paper and cardboard – some of which is produced by us – into new products, we’re preventing them from becoming waste, and we’re using waste as a resource for our manufacturing operations.
DS Smith’s further zero waste ambitions are built into our Sustainability Strategy. Three of our targets are to
- send zero waste to landfill by 2030,
- grow our net positive recycling position, and
- manufacture 100% reusable or recyclable packaging by 2025.
Working toward each of these targets will help us to reduce our waste and to recycle more.
What is a ‘net positive’ recycling position?
‘Net positive’ means the overall impact of the whole of the DS Smith Group’s operations – it’s not just referring to our own waste streams. As a Group, we manufacture around 4.5 million tonnes of packaging annually across the Packaging and Plastics Divisions. However, the Recycling and Paper Divisions manage over 5 million tonnes of material for recycling every year, which means that, as a Group, we are recycling more than we produce.
Part of our Sustainability Strategy is to grow this position, to make sure that, as the Group grows, DS Smith is always able to recycle more material than we produce.
What steps are DS Smith taking toward zero waste?
When we collect cardboard for recycling, we’re using someone else’s waste as a resource for our own manufacturing process. But the idea that ‘waste is a resource’ goes beyond just our feedstocks – it can apply to our own operations, too.
There are teams across DS Smith who will look at the waste from one area of the business, and see if it can be turned into something useful once more. For example, our paper mills gather up the plastics that are removed from the paper that we recycle – approximately 32,000 tonnes of plastic every year are extracted from our pulpers. As a result, projects around the business have been working to find ways of using that plastic again.
Aschaffenburg Mill, in Germany, has worked with the Plastics Division in Croatia to create a closed plastics recycling loop within our business, using mill waste as a resource. The light rejects extracted from the mill eventually become an award-winning plastic product called ‘Beaulex’.
Similarly, most of our packaging plants have underfloor conveyor belts, which collect up 636,000 tonnes of recycled cardboard off-cuts from the manufacturing process. These off-cuts are often sent back to paper mills to be recycled into cardboard once more, but in the UK, a team at Blunhum Packaging and the Recycling Division work together to turn the off-cuts into a new product called BedKind.
BedKind is a premium cardboard animal bedding that’s great for horses because it’s low in dust, highly insulating, and extremely absorbent, keeping them warm, dry, and comfortable at night. It also composts much more quickly than other types of animal bedding, and has several key benefits if used as a fertiliser on farmland, increasing soil quality and supporting crop growth – so it’s great for horse owners, too.
These are just some of the examples of the work that’s being done by teams across the business to explore ways we can work toward zero waste. If you’re interested in helping to reduce waste, check out our tips for a zero waste office!
