If you feel that your EPS product has come to the end of its life as a cool box / mug mailer / corner / packaging etc. it doesn't need to end up in land fill. EPS is actually 100% recyclable (providing it is contaminant free) and also has loads of alternative uses!
  • Break your EPS into big chunks and place in the bottom of window boxes, pots, tubs or hanging baskets, under the compost. It helps with drainage, so plants don't become waterlogged. It also reduces the risk of roots freezing in winter - EPS is a great insulator!
  • Break into tiny pieces and incorporate into garden compost. Soil will be more aerated, you'll use less compost and the soil will be lighter with better drainage.
  • Reuse as packaging - EPS is a great shock absorber.
  • Junk modelling with the kids!
  • Planters for the garden. Our EPS boxes are deep and perfect for carrots, leeks and mushrooms!
