Lasers Stamp Prices on European Produce
Food retailers are aiming to cut plastic and cardboard packaging by ditching stickers on fruits and vegetables, instead using high-tech laser “natural branding” and creating huge savings in materials, energy and CO2 emissions.
Pilot projects are underway in Europe with organic avocados, sweet potatoes and coconuts.
The technique uses a strong light to remove pigment from the skin of produce. The mark is invisible once the skin is removed and doesn’t affect shelf life or produce quality. The laser technology also creates less than 1 percent of the carbon emissions needed to produce a similar-sized sticker.
