• the invention will be better understood on reading the following description, with reference to the appended figure, which shows schematically the apparatus for obtaining the plant support. Detailed description of the invention
• Organic waste 7 and 10 are recovered and then sorted into classes according to the abundance in minerals (weight of the mineral with respect to the dry weight of the organic waste). For example, waste that is rich in iron, but has an intermediate content of potassium, phosphorus and nitrogen, or waste rich in phosphorus, but having an intermediate content of potassium, iron and nitrogen, will represent two distinct classes.
• the skilled person is well aware of the mineral content of various organic compounds, plants or animals and is therefore able to select and assemble into classes according to the requirements of the plants to be cultivated.
• the organic waste 7 is sorted into a class 8, relatively rich in potassium, including tomatoes, zucchini and peppers.
• Other classes can be obtained from legumes (rich in nitrogen), cabbage (rich in iron), or waste from green areas (less rich in minerals) and mixtures thereof.
• the organic waste 7 and 10, and the sorted classes 8 and 1 1 may be identical, depending on whether the waste is intended for incineration in a boiler 2 or kneaded in a mixing unit (kneader) 6, or different.
• the waste of tomatoes, zucchini and peppers to be incinerated are enriched with fish bones and bone marrow.
• these two classes 8 and 1 1 overlap here in part. It is therefore again provided here that these wastes are different, the wastes intended to be mixed being exclusively derived from plants, whereas the wastes 7 intended for incineration, or at least those of certain classes 8 which are derived therefrom, contain animal waste, richer in phosphorus.
• the waste classes 8 for incineration are distributed here in the different compartments 3 of the boiler 2 to produce various classes of ash; here a class 9 is illustrated, for example that resulting from waste tomatoes, zucchini, peppers, fish bones and bones. He is at note that the boiler may only include one compartment, for the incineration of one class at a time.
• a burner 1 initiates the combustion and the heat generated by the incineration of the waste is used here to (i) cause a moderate heating 4 of the mixer 6, which allows to partially dehydrate the waste during mixing and (ii) control the drive 5 of the kneading member 13 of the kneader 6.
• a turbine 14 and a motor 15, mounted here on the shaft 16 of the kneading member 13, are mounted between the boiler 2 and the kneader 6, here a screw.
• a class of waste 1 1 for kneading is kneaded so as to reduce the activity of microorganisms.
• pellets 12 are obtained. This simplifies the logistics, better control of the residual water content and hence an effective reduction of the activity of microorganisms.
• the products resulting from the kneader 6 can be prepared in other forms, such as granules or an amorphous powder, provided that the activity of the microorganisms is reduced therein. This can be achieved through proper packaging, for example impervious to water to prevent rehydration or atmospheric gases and enclosing an inert atmosphere, to inhibit the metabolism of these microorganisms.
• the pellets 12 are incubated, here in the presence of water and a class of ash 9 resulting from the incineration.
• the activity of the microorganisms that were present resumed.
• the microorganisms multiply and initiate the mineralization of pellets 12.
• exogenous microorganisms to those present in the kneaded material, for example microorganisms which will have a positive effect on plant culture, such as microorganisms establishing symbiosis with root level of the plant.
• the "culture support" of the present application can be defined as an organic material which has been kneaded and which has a porosity suitable for the development of the roots of the plants to be cultivated.
• This culture support must be incubated in order to restart the activity of microorganisms present, here also with water, ashes from incineration and exogenous microorganisms.
• the product obtained during mixing will have a mineral content that will be determined according to the normal needs of the plants to be cultivated, depending on the species that will be cultivated, while the incineration ash will have a mineral content that may vary somewhat. for example to meet the increased needs of plants during critical phases of their development, such as germination or fruiting.
• Part of the organic waste may be of the same species as that of the plants to be cultivated.
• both the product resulting from the kneading and the ashes must be suitable for growing plants.
• the mixing results in a product with reduced microbial activity that is homogeneous, that is to say that the different biological waste can no longer be identified or isolated at the end of the mixing step.
• the “reduced microbial” activity is that of a composition in which either the capacity of the microorganisms to multiply, or their capacity to degrade biomolecules, or their capacity to release mineral elements from the kneaded material, is reduced.
• activity to be “reduced”
• at least one of the above three parameters must be reduced by at least 50%, preferably at least 75%, and even at least 90%.
• the reduction of microbial activity provides a juice, loaded with mineral salts and water, which can be used later to rebalance the needs of nutrients according to the stage of their growth and the activity of microorganisms.
• the microbial activity is first reduced because of the mixing step, then restarted, which means that the microbial activity present in the material kneaded and incubated is greater than that present in the organic material just after the step mixing.
• the incubated material will advantageously have at least 75%, preferably at least 80%, or even at least 90% of the initial microbial activity, this parameter being preferably obtained without the addition of exogenous microorganisms.
