    PREPARATION EXAMPLE 1

    [0496] The Preparation of a Material 1

    [0497] Waste wood chips and separated manure, which was disinfected and sterilized by placing it in saline, were mixed in a weight ratio of 2:1. The mixture was crushed with a turbo mill. Thereafter, to this comminuted mixture, 0.5 wt.-% H.sub.4[Si(W.sub.3O.sub.10).sub.4]xH.sub.2O as biocide and 30 wt.-% biochar having an average particle size of 100 m was added. The mixture was slurried with a little water, further comminuted in a ball mill and homogenized. Subsequently, the homogenized mixture was dried to a water content of 10 wt.-%. The weight percentages given above are based on the total amount of the mixture. The water content served to improve the processability of the resulting mixture of wood, separated manure, biocide and biochar. The material could easily be stored, transported and processed until further use. It was completely odorless and was not affected by prolonged storage of microorganisms.

    PREPARATION EXAMPLE 2

    [0498] The Preparation of a Material 2

    [0499] Separated manure, which had been disinfected and sterilized by placing it in saline, was comminuted with a turbo mill. Thereafter, to the comminuted separated manure 0.5 wt.-% H.sub.4[Si(W.sub.3O.sub.10).sub.4]xH.sub.2O as biocide and with 30 wt.-% was added. The mixture was slurried with dilute water, further comminuted in a ball mill and homogenized. Subsequently, the homogenized mixture was dried to a water content of 10 wt.-%. The weight percentages given above are based on the total amount of the mixture. The water content served to improve the processability of the resulting mixture of separated manure, biocide and biochar. The material could easily be stored, transported and processed until further use. It was completely odorless and was not affected by prolonged storage of microorganisms.

    DETAILED DESCRIPTION OF THE FIGURES

    [0501] FIG. 1a shows a plan view of a longitudinal section through a shelf 1 with notches 3. FIG. 1b shows a plan view of the notched side 2b of the shelf 1 with the notches 3.

    [0502] The shelf V 1 was made of the material 1 of Preparation Example 1 through pressing at high pressure.

    [0503] The shelf V 1 had a smooth surface 2a, which could also have notches 3 if necessary. In the notched surface 2b of the shelf 1, the notches 3 were milled. Due to the notches, the surface 2b was larger and could now absorb more pollutants and/or VOC. Furthermore, the air could circulate through the notches 3 and thus be cleaned of VOC, pollutants microorganisms.

    [0504] FIG. 2

    [0505] FIG. 2 shows a plan view of the upper edge 7 of a partition 4 with vertical holes 6.

    [0506] The partition V 4 was made of the material 1 of Preparation Example 1 through pressing at high pressure. The partition V 4 had vertical holes 6. Through the vertical holes 6, the surface of the partition V 4, but especially the carbon, was larger, and this could now absorb more pollutants and/or VOC. Furthermore, the air could circulate through the holes 6 and thus be cleaned of VOC, pollutants and microorganisms.

    [0507] FIG. 3

    [0508] FIG. 3 shows the plan view of a door surface 12 of a door leaf 8 with an upper edge 9, a lower edge 10 and two side edges 11a and 11b. In the door surface 12 a rectangular piece was milled out at the top edge 9, the cutout 13. It was dimensioned such that a perforated grid 14 made of material 1 of Production Example 1, produced through pressing at high pressure, could be fitted as an exchangeable carbon filter insert. The perforated grid 14 was able to absorb pollutants and/or VOC from the air stream through which it flowed. In addition, they were biocidal.

    [0509] FIG. 4

    [0510] FIG. 4 shows a plan view of a longitudinal section through a ceiling panel 15 with a through bore 19 with a perforated grid 14, as described in FIG. 3, and a plan view of a cutout A on the inner surface 16 of the ceiling panel 15.

    [0511] The ceiling panels 15 further have an outer surface 17 and side edges 15. Behind the outer surface 17, an air flow 22 was moved by an electric fan 20. The electric fan 20 was connected via the electrical connections 21 to a solar cell.

    [0512] Through these ceiling panels 15, the indoor air could be effectively cleaned of pollutants and/or VOC. In addition, they were biocidal.

    [0513] FIGS. 5 to 7

    [0514] FIG. 5 shows a plan view of the longitudinal section through the upper region of a door leaf V, 23.

    [0515] FIG. 6 shows a plan view of the cross section through the upper region of the door leaf V, 23.

    [0516] The figure numeral 7 shows a plan view of the upper edge of the door leaf upper horizontal portion of the peripheral edge of the door leaf V, 23 in the region of the cover plate 26

    [0517] The upper portion 23 of the door leaf 23 had an outer side 23.2 and an inner side 23.3 and a door leaf V, 23 circumferential counterpart 23.1 to the door frame with a circumferential stop surface 23.5 to the door frame and a peripheral upper edge 23.6. The door leaf V, 23 was essentially made of pressed chipboard and had ventilation slots and ventilation holes on the lower edge.

    [0518] In the upper horizontal portion 23.4 of the peripheral edge of the door panel V, 23 a cutout 23.4 was centrally arranged, which had a peripheral bearing surface 24.1 for the cover plate 26 made of stainless steel. The cover plate 26 had except for the section with which it serves on the rotating support surface 24.1, holes as air passage 26.1. In the area of the peripheral bearing surface 24.1, the cover plate 26 was secured with countersunk screws 27, 27.1 made of stainless steel.

    [0519] On the inside of the cover plate, a bag 25 was attached. The bag 25 consisted of a close-meshed network of cotton fibers and contained spherical shaped parts F of a diameter of 0.5 cm from the material 2 of Preparation Example 2.

    [0520] By means of this device V, 23, 25, F according to the invention, it was possible to remove the VOC and pollutants still present in the door leaf 23. In addition, the door frame in contact with the door leaf 23 could also be freed of these pollutants. The same applied to the room air circulating through and around the inventive device V, 23, 25, F. In addition, the spherical molded parts F had biocidal properties.

    [0521] FIG. 8

    [0522] FIG. 8 shows a longitudinal section through a pipe V, 28 according to the invention with a pipe wall 28.1 made of hardwood. The tube V, 28 had a packed bed 29. The bulk bed 29 consisted of Raschig rings as molded parts F. The Raschig rings were made of the material 2 of Preparation Example 2. The bulk bed 29, F was flowed through by an air flow 30 in the arrow direction, the air was freed from VOC, pollutants and microorganisms. The tube V, 28 according to the invention was therefore ideal for use in air conditioning systems.

    [0523] A decisive advantage of the devices V according to the invention according to FIGS. 1 to 8 was given by their compostability.
