Soft (Plastics) Sell?

Soft plastic packaging, like polypropylene, is difficult to recycle. Such material's not even currently collected by UK councils. In 2021, Sainsbury supermarkets announced an "..innovative recycling system (that) allows customers to recycle polypropylene film found in several household products". Such packaging was returned to the store by the customer (driven by car?), baled and sent for 'recycling'. Very soon, another supermarket chain, Tesco, claimed to have adopted a similar system. Campaigners, Everyday Plastic, along with the Environmental Investigation Agency, surreptitiously inserted trackers inside 40 packages of soft plastics, collected by Sainsbury and Tesco supermarkets. They found that 17 reached their end destinations. Twelve of the 17 were then used as fuel pellets or burned for energy. From this, Everyday Plastics concludes that 70% of soft plastics collected in supermarket recycling schemes, is being burned (https://www.theguardian.com/environment/2024/oct/01/soft-plastic-collected-for-recycling-burned-tesco-sainsburys-campaigners). The results of this investigation clearly confirms that customers are being misled. The customers will be believing that returning their soft plastics to the store is having a beneficial environmental effect. It's, however, very difficult to put a precise figure on the extent to which soft plastics are being burned. Presumably, trackers were only inserted in bales from a relatively small number of stores. Twenty-three of the trackers appear to have been detected (ansd removed?), before reaching their planned end destination. Perhaps such end destinations changed (for better or for worse?)? It's consequently highly uncertain what happened to these bales. It's also difficult to know, which party is the prime misleader. Perhaps the supermarkets know their schemes are flawed. It could also be the case, however, that folk at the end destinations are misleading the supermarkets. It could even be a combination.
