Arla yoghurt in the old Tetra Brik carton or Arla's new Tetra Top with plasttopp
Tetra Top is reclosable. It is missing on expired Tetra Brik, who, however, was easier to empty.
Plasttopp and lower transport efficiency provides increased carbon footprint, the plastic by about 30 percent.

Good morning juice in liquid or plastic bottle
Equivalent. Both have screw caps. Organic juice in a bottle much more expensive, costing 32,35 per litre including a lien against 19.50 for regular in cartons in the store DN acted.
the Carton 33 grams per 1 liter of plus used in 3 grams of gives 98 per cent less plastic per litre against the plastic bottle in PET with a pant that weighs 41 grams. The bottle's plastic cap of 3.5 grams in the black plastic does not go to materialsortera or recycle. A quarter of the plastic of the PET bottle recycled according to the manufacturer.
of Course, vätskekartongen.
Good morning-juice in the plastic bottle or Froosh mango & orange smoothie in glass bottle
Equivalent. Both are translucent, both have a screw cap.
the plastic bottle in PET (recycled to 25 %) with pant weighs 41 grams. Lock on 3.5 ounces of black plastic is not recycling. The glass vial weighs 359 grams and the lid of the metal is 6 grams.
the plastic bottle. The glass is heavier to transport, both empty to the factory and filled to the consumer.

Zeta beans in tetra or in a can of metal
Konservburken denser which gives longer durability. Jar more resistant to shock than tetra. Just as easy to empty.
Tetran weighs 17 grams, the can 59,5 grams. Tetra is means that the plans we to manufacture and recycle, but the jar and recycled in a higher degree.
About 125 percent greater transportation needs with jar depending on the distance, mainly for the carton is transported on a reel to the factory, while the cans are shipped empty. Square shape takes up less room than round.
Tetran. A life cycle assessment Tetra Pak ordered provides more than 70 per cent smaller carbon footprint with the cardboard box instead of jar.
drinking yoghurt in the carton with plasttopp (Coop), round plastic bottle (Yalla!) or curvy plastic (Danone Activa)
the Same durability. Just as easy to empty.
Coops yogurt drink weighs 18,5 grams and contains 69% less plastic for the same amount of drink compared to Yalla which is the heaviest of 23.5 grams of plastic. Activa weighs 20 grams.
the Plastic in the Yalla! is PET, which is recyclable but for which there is insufficient demand. The plastic in Danone is HDPE which is recyclable. Where is today's demand.
30-50% more for the bottles than the Coops tetra. The curvy takes the most space.

Salad in a 30 gram bag against the salad in the 65 gram bag,
Equivalent so long as everything is consumed.
The smaller packaging requires 25% more plastic for the same amount of salad.
high risk salad in the opened bag is thrown away, because it is quickly becoming its. A british study has shown that 26 of 65 grams is thrown away.
If the plastic recycled is equivalent to the extra plaståtgången from the less packaging 2 grams of discarded lettuce from the big. If the plastic is disposed corresponding to the extra resin 5 grams. A bag of 30 grams is, therefore, environmentally the best, if it often makes the salad left in the larger packaging.Salladsmix in plastic bag. Photo: Börge Nilsson
Zeta beans in tetra 190 grams or 380 grams
Equivalent. Kilopriset much higher for a small package.
the Cardboard in two. The large weighs 17 grams, the small 11,5 grams.
Difficult to save leftover beans in a fresh way. Big risk that they are thrown away.
The large package if all is used, otherwise the small be the best.
Cheese in the piece (750 grams) or sliced (150 grams)
the Cheese in a bit must be stored in containers or an extra bag in order to not dry, sliced fastening.
Both have laminated plastic that cannot be recycled. In the researchers ' sample calculations used 6 ounces of plastic to a piece of cheese 750 grams, and 11 grams to a pack with 150 grams of sliced cheese. It gives ten times more plastic per pound for the sliced.
Because the cheese has a high carbon footprint, it is sufficient to toss 16 ounces, about two discs, to food wastage will have a greater carbon footprint than the plastic.
Depends on. If all the cheese is eaten is the large bit of the best. Becomes ostskalken left and at least 16 grams is thrown away is the sliced better.Round 4 – the Protection of food
Cucumber in plastic wrap or cucumber in bulk
Plastic protects better
2 grams of plastic film.
the Cucumber is quickly becoming its. Cucumber in plastic film gives the six-day longer shelf life in the cabinet or refrigerator.
Cucumber in plastic film, if it contributes to more of the cucumber is eaten.Round 5 – Easy to empty
Arla yoghurts in Tetra Top or Valio yoghurt in a Tetra Rex
Both have screw caps and can be stored lying down. Tetra Rex have a flat bottom, which will be folded in order to be able to be emptied. Tetra Top has tabs that must be folded out.
Quite equivalent, but the Tetra Rex fully plant-based. Tetra Top includes the plastic at the top.
Around 10 per cent (8% – 12%) of the content gets left in the pack when the yoghurt poured out until it stopped flowing. In order to get out of the last need to both flatten and be pinched out. At Tetra Top to plasttoppen to be demolished by the with a thumb grip, which requires a lot of effort and mess. At Tetra Rex it does not tear off, but can flatten.
the Tetra Rex is easier to drain the yogurt, and lower food waste. Since it is completely plant-based have the possibly slightly smaller carbon footprint overall.Round 6 – Easy to sort and recycle
Coop mince in the plasttub or Coop mince in the transparent plasttråg
ground beef in a tube has a longer shelf life. Both recycling.
The transparent plasttråget which, according to our previous study weighing 21 grams contains only one material and is easy to sort and recycle, and is much better than the colored trays are not recycled. The plastic tube of 6 grams, according to the previous study, it has metal clips at the ends which is difficult to remove. The tray feels relatively clean, because the paper in the bottom sucks up the juices. The tube feels sticky and thrown away probably almost always in the garbage.
Nothing in plasttråget. On plasttub in previous designs stuck according to previous study 10 grams per kilogram at the ends. The plastic on the packaging we have now tested released much better and was basically without food waste.
Less plastic gives the advantage to the tube. But if plasttråget is recovered to almost 100% and the tube is not at all, there is still almost a tie. Metallclipsen should be deleted.ground beef in a tube. Photo: Börge Nilsson Rond 7 – Benefit and climate impact for different foods
Water and soft drinks or dairy products
Water and soft drinks are, strictly speaking, completely unnecessary products. Soft drinks are often harmful, healthy water, nearly all in Sweden dispensed from the faucet. Milk and yoghurt are the other hand foods that contains beneficial nutrients.
The annual consumption of 96 liters of soft drink and water per person is transported almost exclusively in the plastic packaging. The 103 kg of milk and yogurt that we drink will almost just in a box with quite a bit of plastic.
Milk and yoghurt. Although dairy products have much higher carbon footprint, it is something we need. Bottled water and soft drinks is completely unnecessary but consume still about equal amount of transportenergi and much more plastic.Rond 8 – Emissions of greenhouse gases
Greenhouse gas emissions for a household of four people for a week, distributed on the eaten food, food waste and packaging.
Food eaten: 80%
food waste: 18%
Food packaging: 2 per cent
Food eaten: 75%
food waste: 15 percent
the Food's packaging: 10%
Food eaten: 62%
food waste: 26%
the Food's packaging: 12 per cent
Fruit, vegetables and nuts have the lowest carbon footprint. For meat, fish and eggs, the package has the lowest impacts in relation to the food itself.
