DS Smith, U.K., reports that its packaging site in Plymouth, England, has contributed to the 20 metric tons of corrugated board dust collected and sent to the Eden Project (UK) to help turn its food waste into compost. Since 2009, the two companies have highlighted how a manufacturing by-product can be diverted from landfill to have a positive impact on the environment.

The Plymouth site joined the initiative in 2013, following the successful Eden parternship with DS Smith's packaging site in Launceston, England.

DS Smith filters out the dust during its conversion process, as the corrugated board is cut, and collects it in giant bags. The dust is stored on-site ready for the Eden Project to collect when they need it. It is then mixed with the Eden Project’s food waste (which is normally acidic) to create an alkali environment, where composting works best. The waste also soaks up excess water, helping bacteria to thrive.

The nitrogen-rich compost is then mixed with garden waste to make high quality soil that the Eden Project’s gardeners use on the plants.

"This partnership is a great example of how DS Smith can help in its local community and help the environment. With a growing awareness among consumers around sustainability, and due to the highly visible nature of packaging in a world of scarce resources, retailers and manufacturers have to scrutinize the whole supply chain.

"We are committed to running our business in the most sustainable way. Helping the Eden Project is just one way in which DS Smith is demonstrating that," added Tony Foster, sales and marketing director, DS Smith, U.K. Packaging.
