Definitions

  • the invention relates to a sack made of rotten material for collecting moisture-releasing goods, in particular organic waste, and an insert for this sack.
  • moisture-releasing goods e.g. of organic waste in household waste, e.g. Food waste of all kinds, vegetable and fruit bowls, flower remnants, grass clippings, etc.
  • household waste e.g. Food waste of all kinds, vegetable and fruit bowls, flower remnants, grass clippings, etc.
  • wet waste e.g. Grains, leached sugar beet pulp, animal droppings and slaughterhouse waste.
  • wet waste these moisture-releasing goods are hereinafter referred to as "wet waste”.
  • wet waste should not normally be incinerated or landfilled, but should be sent to a composting plant, it is advisable to use sacks made of easily decomposable material that can also be composted.
  • Such bags are preferably made of water vapor permeable materials, such as paper, nonwovens, fabrics or paper-like nonwovens. Have the bags in question however, the disadvantage that they easily soak through, making it difficult to transport the bags.
  • a garbage container in the form of sacks or bags is known, the walls of which consist of a plastic film (e.g. of polyvinyl alcohol) which dissolves in the presence of water at a temperature of at least about 37 ° C.
  • a plastic film e.g. of polyvinyl alcohol
  • microcapsules in the container wall e.g. May contain water or aqueous solutions of bacteria that degrade the polymer film. The microcapsules are destroyed, which accelerates the degradation of the polymer film.
  • the known container does not contain an adsorbent layer with a swellable clay.
  • a carrier bag for moisture-releasing foods such as mussels, is known, the walls of which are made of plastic and on the bottom of which a separate compartment with an adsorbent is arranged, which essentially consists of a powder of crosslinked carboxymethyl cellulose.
  • the walls of the carrier bag are made of a non-rotting material.
  • the invention is therefore based on the object to develop a bag that is able to remove moisture from the Vacuum wet waste without losing any noticeable strength, while preventing unpleasant smells from escaping.
  • the sack should also be compostable.
  • One of the sub-tasks underlying the invention is the development of an absorbent insert.
  • the object to be achieved is achieved with the aid of a sack of the type defined at the outset, which is characterized in that it contains an adsorbent layer at least in the base region, the adsorbent being a swellable clay.
  • the adsorbent layer is designed as an insert, in which the adsorbent is enclosed between two walls made of decomposable material, at least the upper one of which is permeable to moisture.
  • the insert is placed loosely on the sack bottom and its cross-sectional dimensions correspond approximately to the area of the sack bottom.
  • the invention further relates to the insert itself, which is preferably in the sack, but also in any other container, e.g. can be placed on the floor of a household rubbish bin or a dumpster.
  • the sack according to the invention is designed in the bottom region as a double-wall sack, the adsorbent layer being arranged between the outer wall and the inner wall.
  • the outer and inner walls can be made of the same rotting material or a combination of two rotting materials. So it is e.g. possible to use a paper bag lined with gauze on the inside.
  • the moisture permeability of the outer wall can be higher than that of the inner wall, so that the sack still has a certain strength, even if the capacity of the adsorbent is exhausted.
  • the intermediate layer containing the adsorbent is only present in the bottom area, since the bottom area is exposed to the greatest loads.
  • the intermediate layer containing the adsorbent can, however, also be provided in the side parts of the bag, the intermediate layer preferably being divided into separate individual chambers.
  • the individual chambers can be obtained by gluing or sewing the inner and outer walls together and filled with adsorbent. This enables a uniform distribution of the adsorbent.
  • the layer thickness of the adsorbent can vary within wide limits.
  • the adsorbent layer is preferably about 1 to 2 cm thick.
  • the swellable clay used according to the invention as an adsorbent also represents a material which accelerates the composting of organic waste and improves the soil. Bentonite can be used. Due to their high swelling capacity, the clays are characterized by a high water retention capacity and thus ensure a reliable binding of moisture from wet waste. The clays are also characterized by a high adsorption capacity, so that the odor is completely absorbed.
  • Bentonite and other swellable clays also accelerate the composting of organic waste and also have a soil-improving effect in that, in addition to water due to their ion exchange capacity, they bind mineral nutrients and only gradually release them again to the plants, which means that these swellable clays can be used as adsorbents in the intermediate layer In addition to the safe and odorless collection and transport of organic waste, the composting process is accelerated at the same time.
  • Bentonite and other swellable clays also have the property of buffering the pH of the leachate that may escape from the waste.
  • the adsorbent is therefore preferably mixed with a moisture-conducting material which, due to its wicking effect, facilitates the transport of moisture from the surface into the interior of the adsorbent.
  • moisture-containing Material can be used, for example, shredded paper, such as newspaper shredder, sawdust, woodchips, textile fibers (eg from rags), sand, rock flour or bone meal.
  • the adsorbent can also be mixed with an oxidizing agent such as calcium peroxide.
  • an oxidizing agent such as calcium peroxide.
  • the use of calcium peroxide has an advantageous effect on accelerated, aerobic composting of vegetable waste, namely through a slow release of oxygen, combined with simultaneous neutralization of the compost by the lime formed. Calcium peroxide also has a strong decomposing effect on odorants.
  • fragrances can also be added to cover the odor.
  • FIG. 1 there is a loose insert in a sack made of decomposable material, the outer wall of which is designated 1 in both the bottom region and the side wall region, in which the adsorbent 3 is enclosed between two walls 1a and 2a made of decomposable material .
  • At least the upper wall 2a is permeable to moisture, while the lower wall 1a is not permeable to moisture needs or may have a lower moisture permeability than the top wall 2a.
  • the insert can also be placed on the bottom of any other waste container, e.g. on the bottom of a metal or plastic container, but then the side walls of the container come into contact with the waste, so that the cleaning effort is higher.
  • the outer wall is denoted by 1 both in the bottom area and in the side wall area.
  • the intermediate layer 3 containing an adsorbent in the bottom region.
  • the intermediate layer 3 can also be divided into individual chambers in the embodiment of FIG. 2, but this is generally not necessary here (in particular in the case of smaller bags). , because the adsorbent layer is arranged horizontally.
  • FIG. 3 corresponds to the embodiment of FIG. 2 in the bottom area. However, it is not single-walled in the side wall area, but also double-walled.
  • the outer wall 1 and the inner wall 2 are connected to one another at the adhesive or seam locations 4, as a result of which the individual chambers 5 are formed for receiving the adsorbent, which cannot slide downward.
  • This embodiment is particularly suitable for absorbing goods that are highly moisture-containing and / or have a strong odor.
  • the sacks of the invention were tested for the effect of the adsorbent on moisture retention, sack strength and odor levels.
  • the onset of putrefaction of the waste can be postponed by 2 to 3 days due to the bentonite insert, so that the organic waste can be collected for up to 5 days without noticeable odor pollution.
  • the paper bags with bentonite inlay have not lost their strength even after 5 days, so that they can be easily transported.
