The invention relates to a process for recycling organic waste with the goal of Dauerhumus- and Substrate composition in which the organic waste is crushed and decomposed as humus products

be reusable. The invention further relates to a rotting device for receiving one or more board rentals

Implementation of said method. With the landfill space becoming increasingly scarce, the recycling of organic waste is constantly increasing

becoming increasingly important. In addition, there is a constant need for natural substrates and fertilizers both in the commercial agriculture, the commercial and landscape gardening as well as in the private garden area.

Substrate production goes back far enough into the past, so until about 1939, organic matter such as leaves and Needle litter, made with sand, clay and clay with the addition of compost substrates. From 1948 were then

These clay-peat substrates are cast-resistant, have a high cation exchange capacity for nutrient storage, are weed-free and relatively inexpensive, however, increased peat extraction leads to groundwater level reduction related damage to whole areas.

It is therefore an object of the present invention to provide a method and oine device with which the organic

natural green wastes are microbially digested, rebuilt and built into permanent humus forms in an economical manner, whereby the full sanitation can be ensured, in particular the natural rotting operations are to take place in a very short time and the humus products produced have a high biological stability and uniformity.

This object is achieved by the method described in claim 1 or by that described in claim 16 Rottevorrichtung solved. Further developments of the method are in claims 2 to 15 and the device in claims 17 to 38

described.

The inventive method is characterized in that the organic waste - possibly after intermediate storage -

Crushing and beating in the fiber longitudinal direction comminuted, mixed and moistened to a water content of more than 50 to 65-vol .-%, preferably 60 vol .-%, based on the total mass. Depending on the starting material lie

Carbon-to-nitrogen ratio of up to 500: 1 before. By crushing and mixing the substances they are Initial ratios optimized so that the carbon-nitrogen ratio is 80: 1 to a maximum of 100: 1. In the Crushing does not only depend on the degree of comminution but, above all, on the surface texture

the crushed organic masses, which plays an important role for the microwave stocking.

What is essential is the fibrillation of the organic material in the longitudinal direction, which makes it possible for a maximum, for the Microorganisms to create easily accessible surface. This is not only true, but especially for the woody portion of

organic masses.

The water content of 50 to 65 vol .-% is composed of the water content of the starting material and the Moisten added water. When putting the rottenfähigen panel rental outdoors is on a uniform structuring

pay attention to the rent in order to prevent nests with the result of anaerobic zones. The Z. B. for strong

Rainwater entering the panel rental evaporates after saturation of the material or sinks as excess water

to the bottom of the table rental and is deducted there. As a result, it is also ensured in addition to the water enforcement that the panel rental is always ventilated without costly additional ventilation in the purchase and operation,

Slotted plates, fans, suction systems or the like are needed. The water content of the table rental according to the invention results in very specific biocenoses. These are first and foremost Molds and actinomycetes. Furthermore, about the CO ₂ production caused by the conversion of organic matter

in conjunction with the addition of water under acid formation, the pH is deliberately controlled to approximately neutral values (pH = 7). The liquid collecting at the bottom of the rivet can flow downwards and is preferably used for (re)

Humidification of the panel rental used.

In the windrow the temperature rises to values of up to 8O ⁰ C, before it decreases to a value below 65 ⁰ C after 15 to 20 days. During this time, aerobic conditions are formed on the degradation of organic substances specialized, in the composition temperature-specific changing communities, so-called biocenoses consisting of masophagous decomposing organisms -, yeasts and mixed cultures, which are everywhere where the first digestion of organic Mass done by the mushrooms. From the conclusion of this phase by increasing the temperature built mushroom mass serves, inter alia, aerobic bacteria as a food source.

Due to the excess of water (up to 65VoI .-%) arises in the rent very quickly a humid-warm climate, in which even stubborn permanent pore forms and seeds willingly swell and germinate. In the germinated state they are safely killed above 53 ⁰ C by coagulation of their protein. The fungus species that dominate during the mining and conversion phase also contribute significantly to the hygienisation of organic matter. By delivering specific bacterial toxins into the surrounding moist solution, eg from Penicillium - the brush mold -, Penicillium notatum, Penicillium chrysogonum and other works, antibiotics are released into the humid environment, which inhibit the synthesis of bacterial cell walls or even actively suppress or dissolve. Thus, even in the reconstruction and construction phase (after the conversion of the panel rental material), an effective sanitizing effect is still obtained, which reliably suppresses re-infections, eg by approach during the transfer process.

After the table rental has been implemented after lowering the temperature below 65 ⁰ C to another place, the Tafelmietenmaterial forced again mixed, broken, restructured and possibly moistened, rise the temperatures in the so-called n Rotetzetafelmiete again upvalues up to 65 ⁰ C. This temperature range above 5O ⁰ C is important for the degradation of lignins, Peptinen, resins and oils, which are located in the organic starting material. The main reason for the implementation of panel rental is in particular that the hitherto not sanitized outer layer of about 16Vol .-% of the total rent is brought into the interior of the new rent to sanitize them by temperatures> 53 ⁰ C. After 66 to 70 days, the fermentation is completed so far that sets a ratio of carbon to dan nitrogen contents of a maximum of 25: 1. This ratio is an indication that the rent is really finished and the conversion of organic matter is completed. Finally, the water content is adjusted to 22% and the Tafelmietenmaterial screened without the usual bonding or lumping, as in previously known methods occur.

Vegetable green waste, such as long grass, leaves, grass clippings, branches, prunings, flowers, crop residues, tree trunks, tree roots, graveyard waste, are preferably used as organic starting raw materials. In addition, the raw materials mentioned ripples, grinding residues from mills in the form of oilseed skins, pomace, beer slurry, consisting of diatomaceous earth, yeasts and malt residues, coconut fibers, barks and chips from the wood and paper industry, tailings from the production of natural sponges, leaves and stalks the canning industry, potato peels and leaf residues from sauerkraut production are added as additives and mixed with the aforementioned organic waste.

Preferably, a carbon-to-nitrogen ratio of 80: 1 to at most 100: 1 is set in the rottenable panel hire by appropriate mixing and comminution in the fiber longitudinal direction, ie digestion, of the starting materials. According to a development of the invention, the rottenfähigen Tafelmieten be at least 15m wide, preferably 17 m, at least 25m long, but not more than 2.8m high. As a result, not only an optimized land use is achieved, but above all a minimization of the free, relatively inactive surface of the rent. The total volume preferably poured is at least 1200m ³ , which compacts after a short time to a maximum height of 2.8m. The ideal ratio in the table rent of the mass to the air, to water is 2: 1: 1, whereby the thickness of the free inactive surface of the table rent amounts to maximally 16% of the total volume with 0,25cm.

The maximum 65VoI .-% excess water of the table rent is, as far as it does not evaporate by itself, drained down through a drain. The substantial temperature derTafelmiete for sanitizing above 53 ⁰ C is preferably set about 15 to 20 days. After the temperature has dropped, the panel rental is converted into a post-mortem panel rental, to moisten it to 50-65% by volume of water used by the water previously withdrawn from the original or another first panel rental. The reuse of the water causes a renewed, very uniform inoculation by the microorganisms in the water takes place. The post-mortem table rental temperatures of preferably more than 55 ° C are set for at least 10 days before the reaction begins to humus, which is noticeable by a significant reduction in temperature. The post-mortem table rent is screened after a total of 66 to 70 days, measured from the time of construction of the (first) Tafelmiete to a maximum particle size of 10mm. The carbon-to-nitrogen ratio before sieving is less than 25: 1. By the final adjustment of the water vapor content to 22%, the rent can be screened off in all weather conditions, without the usual gluing or lumping occur.

The screen overflow occurring in different amounts in the sieving process, depending on the sieve hole width, is freed from the non-compostable materials, such as plastics or bricks, and added again during comminution to the starting material as a seed and structural material, depending on the carbon-nitrogen ratio. This is particularly recommended in the summer months, as during these months large amounts of low-structural monomaterials, such as long grass, incurred. The screen overflow reaches a maximum value of 18% by weight when screening particles larger than 10 mm. The accumulation of non-compostable residues is according to experience, based on the input quantity, on average 1 vol .-%.

The described method with the result of high-quality, despite different starting materials consistent, poor metal pig metals, equipped with high cation exchange capacity and stable Dauerhumusstruktur provided horticultural substrate is ideal for recycling. Dia inventive Rottevorrichtung for purely aerobic composting (fermentation of organic recyclables) is particularly suitable in addition to the aforementioned substances for fermentation residues of any kind, cardboard, paper and other cellulose and lignin, resin, wax and proteinaceous substances. But also oils and fats of animal and vegetable origin can be processed on the rotting device according to the invention, the essential feature of the drainage in conjunction with a targeted irrigation (irrigation) takes place without forced ventilation, rotting boxes, slotted plates or air ducts must be recovered in the table rental. The rotting device can be set up at virtually any location,

including landfills filled with landfills, and has the advantage of being approved by the competent authorities for water protection zones up to Hl / A. The measures provided for the establishment of the rotting device works can be carried out without much effort; The rotting apparatus described in claims 16 to 38 will be described with reference to these works.

First, the soil is drained about 80cm deep and prepared according to the later desired drainage slope towards a drain. To prevent later subsidence, the entire ausgekofferte base is pressed by means of a heavy vibrating plate in different directions. As a basis of the rotting device is preferably created with a corresponding drainage slope 10cm thick layer of sand, consisting of stone-free loamy sand, which is fed, compacted and prepared to a planum. On each of these subsoils, there are provided elevations serving as water barriers, arranged in a grid pattern, each created grid parcel, after filling in the later described "tub", constituting a table renter and having an outlet Each of the thus created outlets is preferably connected to a collection chute located outside the tub On the trough-shaped bed, a 2 mm thick EBC film according to DIN 1632 is drawn in over the entire surface, which is pulled up in the marginal areas to the upper edge of the intended height, so that altogether a completely dense trough is formed According to the drainage gradient, a net of suckers with a gradient of 0.5% and collectors with a gradient of 2% is installed on the surface of the film, the collectors ending in a collecting shaft assigned to the respective renting surface, which is outside the rotting plate For this type of water, the table rent has seeped through and can later be reused to irrigate the post-rotting soil. Up to a height of 15 cm, measured from the surface of the film, a gravel bed of grain size 16/32, in which the suckers and collectors are completely embedded, is now applied. The surface thus prepared is completely covered with a plastic fleece with sufficient overlap in the area of the seams and transitions and a tensile strength of 300 g / m ² . On the retracted fleece is again a 10cm thick layer, consisting of coarse grained sand, starting from the edge, registered.

The total area is now, with the inclusion of the film and the fleece, bordered with a curb, it should be ensured that the edge region is formed so that no water can escape from the tub. Subsequently, a row of Rasengittersteine 40cm χ 60cm in a strong mortar bed on the inside of the curb laid on the intended height of the rotting device. Hereby strong pressures can be intercepted in the edge region of the rotting device when driving with loading or transfer vehicles. The total area is finally filled with a limestone gravel 16/63 in layers to the finished height and compacted. The built-up rotting device with a single-axle load of 7.5 tons at any time of the year with all equipment necessary for composting is passable. In one embodiment of the rotting device instead of the latter 45cm thick support layer consisting of limestone, then applied to the 10cm thick layer of sand consisting of a mixture of Einkorn size 16mm, cement and water layer, followed by a plastic mesh for the purpose of interception of material stresses is relocated. This plastic grid or a corresponding plastic mat serves as a base for a further 10 cm thick layer of the same aforementioned mixture material. This layering is finally compacted with a Stabrüttler and then pulled smooth. After a week of setting time, the surface is passable. The special feature of this layering is also the full water and air permeability, wherein the surface of the device can be cleaned with a sweeper, without thereby fines can clog the pores of the surface. The rotting device not only allows a targeted process parameter monitoring by means of sensors in the rents, but also a catching of the water in the rotting device, which can thickens the Tafelmiete and then each analyzed. Embodiments of the invention are illustrated in the drawings, based on which the invention will be explained in more detail below. Show it

The panel rental 10 shown in FIG. 1 has a width of 17 m, a height of 2.8 m and a length of 25 m. The cross section is trapezoidal, the side edges are inclined at an angle α of 45 ° to the horizontal. The flank width is approx. 3 m in the vertical projection. Since the panel rental in question is outdoors, it is exposed to the rainfall in the area, with the penetrating into the panel rental water partially evaporated again, partly wetted and moistened the material, while the remaining water seeps down through a drain 11, where For example, it can be collected in a reservoir 12. The moisture content of the panel rental 10 is adjusted to 60 vol .-%, based on the total mass, with missing liquid is added via a sprinkler, not shown. The free inactive surface 13 of the panel rental has a thickness of about 25 cm, which accounts for about 16% of the total volume. The distribution of the total table rent to the air is 2: 1, the ratio of the water vapor contained in the table rent to the air is 1: 1.

In the table rental stacked according to FIG. 1, the temperature profile resulting in FIG. 2 results up to the conversion time marked there, wherein the hatched areas respectively represent the period of the 1st and 2nd sanitation. In the second sanitation phase, the material of the inactive outer layer 13, which has reached the interior of the post-rendition rivet, rots in particular. The temperature of the Tafelmiete will initially rise to values above 70 ⁰ C and then fall off again after about 15 to 20 days. If the temperature falls to 53 ⁰ C, then the time is for a conversion of the panel rental. The panel rental is remixed during conversion and forcibly crushed and piled up to a post-mortem panel rental, the temperature of which increases again to values above 60 ° C after the conversion,

until it drops again. After about 66 to 70 days, the entire fermentation is completed, the Dauerhumus can be screened after reducing the water content to about 22%.

The Tafelmieten be constructed on the Rottevorrichtungen shown in Figures 3 to 6. The rotting device shown in Figure 3 has four separated by respective water barriers 18 adjacent Tafelmietenplätze 10, which are traversed by horizontally drawn suckers 14 with 5cm pipe diameter at an equidistant distance, these suckers 14 in a gradient of 0.5% to the water leaking to vertically arranged collectors 15 with 2% precipitation and a pipe diameter of 10cm. These collectors open into a respective collecting shaft 12 with a diameter of 80 cm, which is connected to the sprinkler system, not shown, via a pump. Thus, the leaked water located in the collecting shaft can be used for renewed or additional moistening of a panel rental 10 or a post-mortem panel rental. The Tafelmietenplätze a respective width of 17 m and a length of 25m are surrounded by a paved bypass 16, which is delimited from the Tafolmietenplätzen by lawn pavers 17. The paved bypass 16 is about 5m wide.

As the cross section along the line AA of Fig. 3, shown in Figure 4, it can be seen, the rotting device has the following structure: On an approximately 10cm thick stone-free, layer-wise compacted loamy sand layer 19 dome-shaped water barriers 18 are arranged, consisting of respective 8/20 curbs 20, which are embedded in concrete exist. The height of the water barrier.118 is about 30cm. The rotting device is lined like a trough by a 2 mm thick protective film 22, wherein the protective film 22 is pulled up in the edge region to the upper edge defined by the bypass 16. The protective film 22 is liquid impermeable. In the middle of each Tafelmietenplatzes a collector 15 is arranged with a tube diameter of 10cm, which is supplied via suction 14 with a tube diameter of 5cm each accumulated at the bottom above the film 22 water. On the film with a thickness of 15 cm a layer 23 of 16/32 gravel is arranged, which is covered at the top by a plastic nonwoven 24 a tensile strength of 300g / m ² . About this plastic fleece 24, a further sand layer 25 is arranged about 10 cm thickness, the upper edge but ends below the upper edge of the water barrier 18. At the top, the pan determined by the film 22 is filled with a limestone ballast layer 26 having a thickness of 45 m. Instead of the limestone gravel layer 26, a mixture of einkorn the size of 16mm, cement and water may be arranged. Rasengittersteine 27 are embedded in a mortar bed 28 in the edge region of the rotting device, wherein the mortar bed 28 is lined by gravel 29. The width of this grass paver attachment is 40cm. The rotting device is bounded laterally by embedded in concrete B 100 curbs 8/20 -see 30-, which is followed by a stored in a ballast underpass 16 a width of 5 m to the outside.

Outside the rotting device is located outside the bypass 16, the sequence of layers: loamy sand 31, gravel 32 as "cleanliness layer", a ballast base 33 and a 3cm deep sand bed 34, whereupon the double-T bypass 16 rests It can be seen that the collector 15 opens into an inlet basin 35, which has a diameter of 50 cm and a drain 36, which opens to a collecting shaft 12 with a diameter of 80 cm.The collecting shaft 12 is covered at the top with a passable cover 37 and is located in the area of the bypass 16.

The inlet basin 35 consists essentially of a concrete pipe 38 which is mounted on a concrete ring 39 and has a centrally disposed drain pipe 40. The inlet basin 35 is covered by a lid 41, which is passable if possible. An alternative construction of the rotting apparatus is shown in FIG refer to. This structure differs in that above the 15cm thick layer 23 of gravel 16/32, a layer 25 of sand and two layers 42,43 einkorngemisch 16mm a respective thickness of 10cm are applied, between which a plastic mat 44 is a reinforcement , Instead of the limestone ballast, a mixture of Einkorn the size of 8 to 16mm, cement and water, which is permeable to water, are applied.

The flowchart of Fig. 7, the procedure is shown. For example, collected by collections from house to house organic green waste, such as long grass, foliage, grass clippings, branches, prunings, flowers, crop residues, tree trunks, tree roots, cemetery waste, but also other organic substances in the commercial economy knows, together with in any camps mixed raw materials, with additives such as ripples, grinding residues from mills, such as shells of oilseeds, pomace, beer sludge, coconut fibers, barks and chips from the wood and paper industry, tailings from the production of natural sponges, leaves and stalks from the canning industry, potato peels the potato processing industry as well as leaf residues from sauerkraut production. This mixture is crushed by tearing and beating in the fiber longitudinal direction and heaped up to a table rental after the addition of water. In the present flow diagram, four table rents, called pre-rotting, have been added, the pH of which has been adjusted to 8.5 to 9 and their water content to 60% by volume. After about four to six weeks, the pre-rotting process is completed, which is determined by the conversion time marked in FIG. The Vorrotten be rearranged, which again comes to a mixing and crushing of the board material. The rearranged sheet material is referred to as post-rotting, the seepage can each be recycled to sprinkle the Nachrotte can be used. After completion of the Nachrotte the moisture content is lowered to 22%, the resulting humus can be bagged after sieving and sold. The foreign matter that accumulates during the screening process is collected and sent to a licensed landfill. The overflow of approx. 18% consisting of organic substances resulting from screening is recykled and sent for further comminution and mixing.

According to the state def technique, for example, the following values are known:

GrüneWertstoffa Wood C: N ratios softwoods growth 100-400 Wood 40-80 hardwoods growth burl 100-400 fine roots 30-50 190 rung 55 grasslands root 10-40 straw 10-40 Grain 50-100

In a concrete Ausführungsbaispiel ¹ A softwoods, ¹ A hardwoods, ¹ A meadows and ¹ A straw or hay were mixed together during comminution, so that the CN ratio of 100: 1 and thus simultaneously the pH Value between 8.5 and 9 set. If one of the abovementioned starting materials is not sufficiently available, it can be replaced by another green substance suitable in the CN ratio. By applying the prescribed rotting method, the CN ratio then very rapidly narrows due to the release of the carbon as carbon dioxide, which is then converted by the process according to the invention into 88% carbonic acid with the aid of water.
