BBC:
Laser “tattoos” could remove the need for sticky labels during the sale of fruit, developers say.
The technology removes pigment from the fruit’s surface to show information such as the item’s sell-by date and price.
The process does not affect the taste or the lifespan of the fruit.
I’d never thought about how much those paper labels cost. This is a fascinating idea.
And most important (for me) I won’t have to fiddle around trying to remove them from apples etc, where the seem to stick like they are welded on.
Now if only someone could come up with a way to convert waste plastic to something immediately useful. Like, say, ethanol.
