Not too long ago I stumbled onto this article about laser marking vegetables in Sweden. A company called ICA wanted to have an environmental marking system for their organic produce and were marking avocados and sweet potatoes by laser. Reading more into it I found that similar type of system has been experimented in the UK as well at Marks and Spencers.
So what is it?
EU requires the produce sold to be marked in some way. Up until now most fresh vegetables and fruit had been marked with a sticker. The stickers are made with glue and using dyes to print them and are discarded afterward. The laser, on the other hand, peels off a layer of the vegetable or the fruit leaving a mark on it, which can be eaten or peeled. To top this, the technology produces only 1% of the carbon emission than the production of similarly sized stickers!
Laser tagging is still in its early experimentation and it might not work on all produce, however, I cannot be excited enough to be without the stickers! The annoyance to rip them off and having left with the sticky surface. I am looking forward to Marks and Spencer widening their repertoire of laser tagged produce as well as I hope the rest of the Europe would.
What do you think about laser tagging fresh produce?
