  • the first covering member is cast from metal and the second covering member is cast from concrete.
  • the second covering member may be made from any permanent attachable material.
  • the first covering member is attached to the base member.
  • the second covering member is simultaneously cast (e.g., from concrete - in place) and attached on top of the first covering member for providing better sealing properties by generating pressure on the first covering member.
  • the refuse (or the package or packages thereof) may contain a plurality of strengthening members. This serves to increase the load bearing capacity of the resultant concrete monolith - and this is advantageous when these concrete monoliths are used as building elements (as will be subsequently discussed). For example, the refuse can be compressed into the inner vessel 14.
  • the shape of the packaged refuse is approximately identical to the shape of the volume of the interior of the inner vessel 14.
  • the inner vessel 14 is in the shape of a cube, a rectangular box, a partial sphere, a cylinder, an obelisk or any other suitable form.

  • This air gap 15 includes at least one outlet (indicated by numeral 18 in Fig. 3), for indicating upon completing of the injected sealant process, as the sealant removes the air from the gap (from outlet 18) until it reaches outlet 18. This can be used as an indication of completing the sealant injection process.

  • the second covering member 13 and/or the inner wall of the base member 11 further comprises one or more slits or wider aperture(s) as indicated by numeral 20.
  • Such slits are also filled with the sealant material, for better strengthening the connection between the covering 13 and the base member 11, as this generates an anchoring effect with the sealant material.
  • the second covering member 13 i.e., the covering member
  • the covering member is cast by providing concrete onto the covered inner vessel 14 (which has been placed onto the base member 11 and cover by the first cover 12), and by optionally generating the air gap 15 and its outlet 18.
  • the present invention further comprises using a plurality of such concrete monolith units as building elements for constructing meta-structures on top of the storage platform 1.
  • the method for constructing these meta-structures is comprised of stacking, arranging, attaching or scattering a plurality of these building elements in a predetermined pattern as defined and allocated fro each concrete monolith by the alignment elements formation of the storage platform 1.
  • the spaces between the concrete monolith (i.e., the sealed concrete and refuse filled containers) that are located on top of the storage platform 1 may be filled with concrete or other suitable material (e.g., by casting).
  • the concrete monoliths can be placed in any desired distance one from the other (as set and forced by the formation of the alignment elements), and filling material (such as concrete) can be placed between them, on top of them and beneath the created gap between the bottom of the monolith and the storage platform 1, in uniform manner; thus creating a designed strengthening of the resultant meta-structure (e.g. in cases of cracks developing in individual containers or in the meta-structure).
  • the alignment element 17 located on to of the second cover 13 of concrete monolith 10 generates an option to place another layer of concrete monoliths on top of the first layer and in the same manner, as the a plurality of concrete monolith creates an additional storage platform.
  • meta-structures form a monolith structure which better utilize the area allocated for the disposal site, as each concrete monolith 10 is accurately positioned on top of the storage platform 1.
  • Another advantage of the method and structure suggested by the present invention is that there is no need to build complicated structures with delimitation walls for each concrete monolith, but a simple platform with protrusions and/or apertures. This is a cost effective feature as it saves construction materials such as iron reinforcement rods, cable, wire mesh, or reinforced concrete columns.
  • the concrete monolith unit 10 further comprises guiding elements located on the outer side wall(s) of the container base member of the concrete monolith unit as indicated by the numerals 21 and 22.
  • the guiding elements can be in form of at least one protrusion member 21 located at a first outer side wall of the concrete monolith unit 10 and at least one corresponding hole located at a second outer wall of the concrete monolith unit 10.
  • the guiding elements 21 and 22 can be used for engaging between each two adjacent concrete monolith units, thereby allowing the creation of a wall-like structure made of a plurality of engaged concrete monolith units.
  • a sealant material can be added between each adjacent concrete monolith units of the wall-like structure, thereby creating a structure with enhanced sealed properties.
  • such a wall-like structure can be used as a surrounding wall for a waste pit in a disposal area, such that wall-like structure (depending on the height of the wall-like structure) increases the capacity of the storage pit.
  • the present invention is surprisingly simple and may be used to solve a double problem: it disposes of waste cleanly and effectively - at minimal construction cost and it saves disposal area.
