Colruyt has adapted its Graindor coffee packaging in several stages over the last few years. In 1999, it reduced the thickness of the Graindor tins by 21% from 0,28 mm to 0,22 mm, enabling 50 tons of metal to be saved a year. The weight of the plastic cover was reduced by 31%, from 9,3 grams to 6,4 grams.
Chaudfontaine has changed the packaging of its mineral water. At the same time, it has reduced the weight of its 1,5 litre PET bottles. The bottles previously weighed 41 grams, but now weigh only 31 grams, which represents a yearly saving of 400 tons of plastic.
GB and Carrefour’s regenerating salt for dishwashers used to be sold in packs of 4 kg. GB and Carrefour’s new packaging concept still contains 4 kg, but it is now composed of four individual cardboard dosage units, each holding one kilogram of salt. The designers’ aim of this modification was to make life easier for consumers. The regenerating salt is now presented in packs containing smaller volumes, but the global packaging ratio has improved.
Carrefour has introduced a new bag to package potatoes. Called the Vertisac, this new bag is made of plastic material and manufactured in LDPE by means of a co-extrusion process. This manufacturing process enables a thinner yet more resistant LDPE film to be produced. The new potato bag weighs 20,5 grams, or 3 grams less than the previous bag. The introduction of this new bag follows previous adaptations that had already reduced the weight of the packaging bag for potatoes.
Carrefour Belgium has reduced the weight of its jam pots. The old pots used to weigh 265 grams, whereas the new ones weigh only 250 grams. On an annual basis, this represents a saving of 15 tons of glass.
Bosch has reduced the quantity of plastic film required for its drill packaging by 36%. The company’s new PET tight pack for 12 mm drills contains only 2,3 grams of PET film. The old packaging contained 3,6 grams of PE film.
ANL-Plastics implemented a project to better nest dishes, designed to contain meat, sauces or salads, into each other. As a result, they take up less space, and the outer cardboard packaging can contain twice as many dishes (2,000 instead of 1,000), even though the packaging is smaller than before. This represents a considerable saving in terms of transport (64,000 dishes per pallet instead of 32,000).
