One of the largest British retailers in London, M&S, is opting in for laser-printed barcodes to reduce paper waste. "The labels, which are etched onto fruit's skins with lasers instead of stickers, will save 10 tons of paper and five tons of glue every year according to M&S," reports The Telegraph. The labels will be etched into the skins of avocados, but "could soon be introduced to other fruit and vegetables and adopted by other supermarkets which are looking for new waste reduction techniques." The labels themselves include the shop logo, best before date, country of origin and product code for entering at the till. What's more is that the avocado's skin is the only area impacted by the lasers -- none of the fruit gets damaged. Bruce66423 writes: Print the information usually on the packaging to reduce waste. Excellent idea -- although the Aldi (the radically cheap, all own brand chain) alternative is to leave avocados untouched and get the cashiers to enter the code.
