Swedish supermarkets use Natural Branding aiming to cut plastic packaging by ditching stickers on fruits and vegetables, instead using hi-tech ‘Natural Branding’
Swedish supermarkets use Natural Branding by Laser Food, The humble fruit sticker may seem an unlikely cause for environmental concern but removing it from produce could create huge savings in plastic, energy and CO2 emissions.
In response to consumer demand for less packaging, Dutch fruit and veg supplier Nature & More and Swedish supermarket ICA have joined forces to run a trial to replace sticky labels on organic avocados and sweet potatoes with a laser mark.
M&S are also using it on coconuts in the UK.
Dubbed “Natural Branding by Laser Food”, the technique uses a strong light to remove pigment from the skin of produce. The mark is invisible once skin is removed and doesn’t affect shelf life or eating quality.
“By using Natural Branding by Laser Food on all the organic avocados we would sell in one year we will save 200km (135 miles) of plastic 30cm wide. It’s small but I think it adds up,” says Peter Hagg, ICA business unit manager.
The laser technology also creates less than 1% of the carbon emissions needed to produce a sticker of similar size.
Stephane Merit, business development manager of the Spanish company behind the technology, Laser Food, says with millions of stickers used on food produce around the world everyday, the technology could make a “significant reduction in the amount of paper, ink, glue” being used as well as the cutting the energy used to produce and transport them.
The sustainability saving is particularly important for organic shoppers, who now account for almost a fifth of all ICA’s fruit and veg sales, says Hagg. “Organic sales are driven by environmental awareness, like climate change and belief in health benefits. Younger shoppers also choose products depending on the environmental impact of the packaging. And we know that this will be very important in coming years,” he says.
Switching from plastic to cardboard is a bonus, but selling organic produce as loose is even better says Hagg. Yet under EU rules all items need to be marked hence the need for stickers if selling loose.
“This is a solution that permanently marks the skin of the product, so it’s better from a sustainability perspective, but also avoids the problem of stickers falling off.”
Laser Food’s technology has been around for several years but has previously been used for marketing or branding, without being explicitly linked to sustainability.
“Up to now, no one has used this technique with the specific aim of cutting packaging. It was used for novelty – which is nice, but a gimmick at Easter or Christmas isn’t going to pay off,” says Michaël Wilde, sustainability and communications manager at Nature & More. “What we are saying is, by buying this product you’re saving plastic.”
The cost of a laser machine is considerable, but after that initial investment, Wilde says it is almost more cost-effective than stickers. “You have to invest in an extremely expensive machine, so it’s very much an investment for the future. This is something we believe more and more supermarkets will take on. It saves resources, CO2 and energy, so it does calculate.”
M&S lasered coconuts
While the ICA trial has begun with sweet potatoes and avocados, products where sticking labels to skin is challenging, the supermarket is already preparing to expand onto other products.
“The next step will be to use natural branding on edible skin products, such as apples or nectarines,” says Hagg. “If consumers react positively there is no limit. We are planning to try it with melons in summer, as there is a problem there at the moment with stickers attaching to the skin.”
Although ICA’s involvement is the largest retail trial to date, the technology has been used in various other European markets, and now Swedish supermarkets use Natural Branding.
Last year UK supermarket M&S trialled it on oranges, saving several tonnes of packaging according to fruit technologist Andrew Mellonie, who supervised the project. However, citrus skin’s ability to “heal” itself meant the laser mark wasn’t as effective so the trial was suspended, but the retailer now uses it on coconuts and has plans to extend to other products.
The reaction of shoppers to laser-branded produce is one of the only concerns for Hagg and Wilde, but, they say, so far feedback on Swedish social media has been positive.
For Hagg, no matter how small the story, nowadays sustainability is “always good news” for consumers and he is hopeful that other supermarkets will follow ICA’s example.
“The calculations are that it costs the same, but sustainability for our consumers and ourselves is the biggest gain. I hope it will take off with more products and also non-organic. I can only imagine what a bigger retailer would be able to save. I really hope it spreads.”
