One of the firms which takes pellets from Roydon is British Polythene Industries.
It melts them at about 200C to become liquid. This is then blown into a shape “like a big bubble”, says managing director Andrew Green, before becoming flat plastic.
It is then made into refuse sacks, which are sold within the UK, Ireland and Northern Europe, or building film - for damp-proof courses and so on – which is sold at builders’ merchants.
