Since 2009, more than 20 tonnes of cardboard dust has been provided to the Eden Project to help turn its food waste into compost.
The dust is produced during the conversion process as the corrugated board is cut.
DS Smith’s packaging plant in Launceston, near Plymouth, has been supplying the Eden Project with the dust since 2009.
Keen to recycle its own by-product from the cutting process, the packaging plant joined the initiative in 2013.
DS Smith filters out the by-product during its conversion process and collects it in giant bags. It is then stored on-site ready for the Eden Project to collect when they need it.
The dust 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 great soil that the Eden Project’s gardeners use on the plants.
Tony Foster, sales & marketing director, DS Smith, UK Packaging, said: “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.”
