Definitions

  • the present invention relates to a method and a device for treating organic material and, more specifically, for a treatment of the kind in which the organic material is subjected to a cryogenic freezing process and is disinte- grated to produce a granulate that is subsequently freeze-dried.
  • the remains are usually placed at a depth of 1.8 to 2 metres, where, in the absence of oxygen, a time-consuming anaerobic decomposition takes place under the influence of sulphur-producing mi- croorganisms. Decomposition is slowed down by the anaerobic process as such, but also by the materials that make up the coffin. Moreover, it is generally very difficult for the surrounding vegetation to assimilate the nutrients that are precipitated at that depth.
  • cremation In the case of cremation, on the other hand, ashes rich in mineral are produced which may be spread or interred in an urn at a depth such that an aerobic decomposition takes place and the vegetation is able to easily assimilate the nutrients.
  • the drawback of cremation is, however, the release of toxic substances such as mercury, but also the production of large amounts of carbon dioxide during combustion.
  • considerable amounts of fuel, such as fuel oil, are consumed during cremation, which constitutes both an environmental issue and a cost issue.
  • the process consists in subjecting the coffin, which is usually made of wood, and the remains contained therein to a two-step freez- ing process followed by freeze-drying and disintegration, whereupon the pieces are gathered and placed in a degradable container for final interment.
  • the container disclosed is made of degradable board or peat.
  • the idea behind this type of process is to enable interment of the remains at a depth of about 25 cm, at which depth aerobic decomposition is rendered possible. This results in a considerably faster decomposition process and a process which allows the surrounding soil and vegetation to better and more easily assimilate the precipitated nutrients.
  • one drawback of this method is that the remains have, in their natural state, a lower pH value than the surrounding soil, which causes an acidifying effect on the surrounding soil.
  • an object of the present invention to provide an improved method and an improved device for treating organic material, in which the organic material is frozen, disintegrated and freeze-dried.
  • a further object of the invention is to provide a method and a device of a kind such that a faster decomposition and a favourable effect on the surrounding environment are obtained when interring the disintegrated and freeze-dried organic material.
  • the present invention therefore provides a method having the features stated in claim 1 and a device having the features stated in claim 20. Different embodiments of the method appear from claims 2-19, which are dependent on claim 1 , and different embodiments of the device appear from claims 21- 33, which are dependent on claim 20.
  • the present invention provides a method for treating organic material, comprising the steps of placing the organic material in a first container made of a material that comprises a mineral-based filler and a polyolefin binder, subjecting the container and the organic material to a cryogenic freezing process, subsequently disintegrating both the container and the organic material to produce a granulate, subjecting the granulate to a freeze-drying process to dehydrate the granulate and placing the dehydrated granulate in a second container made of a degradable material that comprises a mineral-based filler and a polyolefin binder.
  • an improved method for treating organic material i.e. human and animal remains. More specifically, a method is provided which results in a faster decomposition and has a favourable effect on the surrounding environment in conjunction with interment. This is achieved by first placing the organic material in a first container made of a material that comprises a mineral-based filler. After being subjected to cryogenic freezing, the organic material and the first container are disintegrated to produce a granulate.
  • granulate is meant a material in particulate form, which may have a particle size in the range 3-8 mm.
  • the water in the granulate is removed through a freeze-drying process, whereupon the dewatered granulate is placed in a second container which too is made of a material that comprises a mineral- based filler.
  • the mineral-based filler has a pH value that is higher than that of the organic material and thus helps to raise the pH value, which in turn helps to reduce acidification.
  • the step of subjecting the granulate to a freeze-drying process may either succeed or precede the step of separating non-organic material from the granulate. This ensures that no metals such as amalgam, mercury, gold or titanium are released into nature in conjunction with interment of the second container and the granulate held therein.
  • the first container may be disintegrated by exposure to an influence in the form of ultrasound, mechanical shocks, pressing or vibration.
  • Pressing may involve applying a pressure on the container or subjecting the container to a rolling procedure.
  • the organic material may be disintegrated by exposure to an influence in the form of ultrasound, mechanical shocks, pressing or vibration.
  • Pressing may involve applying a pressure on the organic material or subjecting the organic material to a rolling procedure. Openings may be made in the container before or during the cryogenic freezing process. This ensures access to the organic material held in the first container during the cryogenic freezing process. The openings may be provided in the form of perforations in the container or by breaking the container during the freezing process. According to one embodiment, the organic material is pre-cooled to a temperature in the range -5 - -20 0 C before being subjected to the cryogenic freezing process. In this way, the amount of energy required for the cryogenic freezing of the organic material is reduced.
  • the method comprises the step of weighing the first container and the organic material before the cryogenic freezing process, and using the result to control said freezing process. This allows optimizing of the energy requirements for the cryogenic freezing of each unique batch of organic material. This optimization may also involve measuring the dimensions of the first container.
  • the method comprises the step of supplying mineral material with the dewatered granulate to the second container. This enables a further increase of the pH value.
  • liquid nitrogen is used in the cryogenic freezing process.
  • the steps of subjecting the container and the organic material to a cryogenic freezing process and subse- quently disintegrating both the container and the organic material to produce a granulate are repeated at least once.
  • the material of which the second container is made may further comprise starch. This allows an accelerated decomposition of the second container when interred.
  • the organic material is wrapped, before being placed in the first container, in cerements made of a material comprising a mineral-based filler and a polyolefin binder. This enables a further increase of the pH value.
  • the present invention further provides a device for treating organic ma- terial that is held in a first container made of a material that comprises a mineral-based filler and a polyolefin binder, comprising a first unit for cryogen freezing and disintegration of said first container and said organic material to produce a granulate, and a second unit for freeze-dry ing of said granulate, the first unit comprising a measuring station for determining measurement data including the weight of the first container and the organic material held therein and a control means for controlling freezing as a function of said measurement data.
  • an improved device for treating organic material is provided. More specifically, the device enables a more environmentally favourable treatment of the organic material.
  • the inventive device is adapted for receiving the organic material held in a container made of a materia! that comprises a mineral-based filler, it is possible to raise the pH value of the granulate obtained in the first unit after cryogenic freezing and subsequent disintegration. Since the inventive device also comprises a measuring station, it is possible to optimize the energy requirements for the cryogenic freezing of each unique batch of organic material.
  • the device comprises a separating means for separating non-organic material from the granulate.
  • the separating means may be arranged for separation of non-organic material from the granulate before or after the freeze-drying thereof.
  • the measuring station is arranged to determine measurement data that also includes the dimensions of the first container.
  • the first unit comprises a vessel for liquid nitrogen, the first container and the organic material held therein being adapted to be placed in said vessel when holding liquid nitrogen in order to achieve said cryogenic freezing.
  • the control means may be adapted to supply a quantity of liquid nitrogen to the vessel, said quantity depending on said measurement data.
  • the device may comprise a lock, which is movable to a position for sealing of said vessel. In this way, it is possible to reduce the evaporation of liquid nitrogen and, thus, to reduce the amount of energy required.

Abstract

Procédé de traitement de matière organique (ex. restes humains ou animaux, corps) avant inhumation. La matière organique est placée dans un conteneur composé d'un matériau qui comprend un agent de remplissage à base minérale et une polyoléfine, et soumise à un processus de surgélation cryogénique. Elle est ensuite désintégrée et la matière granuleuse résultante est placée dans un second conteneur, composé d'un agent de remplissage à base minérale et d'une polyoléfine. L'agent de remplissage à base minérale utilisé dans les conteneurs augmente le pH de la matière organique à inhumer. Il en résulte une dégradation plus efficace ayant moins d'effet sur l'environnement.
