Definitions

  • the present invention relates to a bag, in particular a plastic bag, preferably for the collection and, if necessary, the dispatch of, in particular moist, waste, particularly preferably used coffee capsules or coffee-aluminum capsules.
  • the invention also relates to a method for collecting, in particular moist, waste, particularly preferably moist piece waste.
  • the invention also relates to a method for recycling used coffee capsules, in particular used coffee-aluminum capsules.
  • the invention is based on the use of the bags according to the invention, in particular plastic bags, for the collection and dispatch of, in particular moist, waste, particularly preferably used coffee capsules or coffee-aluminum capsules.
  • Coffee capsules are single-use products. They are regularly used in so-called portion coffee machines. In order to brew the coffee in the capsules, the capsule in the coffee machine is partially destroyed and water or steam heated at high pressure is passed through the coffee powder for a predetermined period of time. The amount of coffee powder present in the coffee capsule is intended for brewing a single cup of coffee. It is therefore a portion packaging. Coffee capsules are still enjoying growing popularity due to their ease of use. An advantage of this type of coffee production is also to have a wide range of different types of coffee available without having to stock large quantities of corresponding types of coffee or beans for each coffee flavor note. To ensure the freshness and integrity of the To be able to guarantee the coffee powder used for this, the coffee capsules used are usually made of an aluminum body and an aluminum cover. After removing the used coffee capsule from the coffee machine, it regularly contains residual water as well as moist coffee grounds.
  • the used coffee capsules if they are not used in, for example, cafes or coffee shops, are often disposed of with the regular household waste and are therefore withdrawn from waste recycling. For Germany alone, the amount of waste due to used coffee capsules was estimated at 4,000 to 4,500 tons in 2014. While the inclusion of coffee aluminum capsules in the recycling process should easily be possible through separate collection, if these aluminum capsules are used in cafés and collected separately, this is more difficult with aluminum capsules that the end consumer takes home and uses there Due to the moisture and contamination with coffee residues or damp coffee grounds, they cannot be collected with the remaining recycling waste without further processing, but must first be cleaned separately by the consumer. This individual cleaning is disadvantageous not least because of the water consumption. This also means that used coffee capsules are thrown into the regular household waste.
  • the EP 3 617 085 A1 a shipping bag in which the opening edge of the front wall is below the opening edge of the rear wall, so that the rear wall forms a protruding, foldable closure flap with a first adhesive strip and wherein the front wall has a third adhesive strip on the outside beyond the area of overlap with the folded closure flap.
