3. Polystyrene packaging
Polystyrene has long been a packaging staple in the foodservice industry. And yet, it contains toxic substances Styrene and Benzene, and is often not recycled in the UK in kerbside recycling (source). You can swap out polystyrene containers for BioBoard takeaway containers, which have the same shape and function, but are instead made from FSC™ certified board sourced from responsibly managed forests.
