Helen Bird, recycling expert for the Waste and Resources Action Programme (WRAP), says there are alternatives to this plastic wrap. PLA is a bioplastic derived from plant sugars. It can be made from sugar, starch, corn, cane, or potatoes. This is considered the greenest wrapper option – it’s compostable, combustible and can be transformed into clean energy. However, it’s also expensive, rips easily and requires more energy to make it.
