- compositions have the advantage of preventing waterlogs from being discharged into sewers or surface water and thus limiting or even preventing environmental pollution.
- use of these compositions can be carried out in a controlled manner in quantity and in time. Indeed, these compositions can be used as fertilizers on cultivated soils, by example for the cultivation of the olive tree.
- the products that were hitherto to be spread at the time of crushing olives (November to January) can be applied at any time of the year and in particular to the optimal period determined by the agronomists for each plant species. (February to May and / or September).
- this type of fertilizer including in particular vegetable water and grease (and possibly sludge or margins) reduces the consumption of chemical fertilizers with the resulting benefits for the agricultural economy, the environment and Sustainable development.
- compositions according to the invention make use of the known characteristic of the use of gypsum as fertilizer through its calcium and sulfur supply or as an additive to other compounds having fertilizing properties.
- compositions according to the invention also offer the following advantages: positive effects on the vegetative growth of the plant or the herbaceous culture after controlled spreading of different quantities of the compositions on the cultivated ground and on the productivity of the crops concerned. - Reduction or elimination of synthetic chemical fertilizers used to fertilize the cultivated soil, by effectively replacing them with the organic and inorganic materials provided by the compositions according to the invention. - improvement of the structure and the chemical composition of the soil thanks to the addition of organic matter and a better balance between C and N. conservation or increase of species and amount of microflora and microfauna of the field.
- the extraction of oleaginous and / or proteinaceous from harvested fruits or seeds is generally carried out continuously or discontinuously by known methods based on pressing and centrifugation, optionally with water injection during these phases. In all cases, these processes generate organic waste either in solid forms (pomace) or in liquid forms (vegetable), or possibly in pasty form (marginons).
- waste distilleries are generally composed of solid or semi-solid materials such as grape marc, pips, pulp and stems.
- liquid or semi-liquid waste is composed of organic matter, mineral matter, nitrogenous materials, fats, often polyphenols and water, the proportions of which vary according to the mode of extraction of plant varieties and of the production period.
- solid or semi-solid waste consists essentially of fibrous elements (for example pulp and stone in the case of the production of olive oil or grape marc, pips, pulp and stalks in the case wine production).
- hydrated calcium sulphate is meant herein the product resulting from the hydraulic setting and hardening of a hydratable calcium sulphate, i.e., anhydrous calcium sulphate.
- the amounts of waste expressed in% by weight of the composition range from 10% to 90%, preferably 10% to 60% and the amounts of hydrated calcium sulphate expressed in% by weight are from 90% to 10%, preferably from 90% to 40%.
- compositions are in any form compatible with the spreading habits of farmers, arboriculturists or winemakers, and preferably in the form of granules or rushes.
- the granules may have diameters ranging from 1 to 20 mm, preferably 3 to 10 mm.
- the rods may have diameters ranging from 3 to 10, preferably 5 to 8 mm and lengths ranging from 3 to 20, preferably 10 to 15 mm.
- the process for the preparation of the compositions according to the invention comprises a step of introduction into an organic waste mixer, of hydratable calcium sulphate and adjuvants known in the art as setting accelerators, possibly of water, then a step of mixing during which the granulation is carried out.
- the hydraulic setting of the hydratable calcium sulfate begins as soon as the water is introduced and ends after the granulation step.
- Waste is usually introduced first.
- the mixture of hydratable calcium sulfate and adjuvants is then introduced.
- the amount of water added depends on the nature of the waste. For liquid waste, no addition of water is made (the water used for hydration is that provided by liquid waste).
- the water used for hydration is that provided by pasty waste.
- the water-to-solid ratio of the hydratable calcium sulfate / waste mixture is between 0.25 and 0.45.
- water is preferably introduced after the waste and hydratable calcium sulfate.
- the ratio between the mass of water supplied and the mass of solid (hydratable calcium sulfate plus waste) is for example between 0.15 and 0.35.
- the respective amounts of waste and hydratable calcium sulphate introduced to obtain the compositions of the invention depend on the type of waste and are in general (expressed in% by weight):
- liquid waste vegetable waters, for example
- a quantity of hydratable calcium sulphate ranging from 70% to 90% by weight and a quantity of liquid waste ranging from 30% to 10% by weight are used.
- a quantity of hydratable calcium sulphate ranging from 80% to 60% by weight and a quantity of solid waste ranging from 20% to 40% by weight is used and the sufficient amount of water for hydraulic setting. Water may preferably be added during, and / or after the waste mixing step and hydratable calcium sulfate.
- any type known in the art can be used, for example gypsum, BMA, aluminum sulfate or zinc, etc.
- the amount is between 1 and 5% by weight, for example.
- waste Insofar as the waste is in general acid, they have a marked retarding effect, which generally leads to a relatively large amount of accelerator.
- Waste that may require an accelerator is liquid and pasty waste.
- any type known in the art for example citric acid, can be used.
- the amount used is between 1 and 3 per thousand by weight, for example. This type of formulation is used for solid and dry waste.
- the granulation is generally concomitant with the kneading step.
- the wet granules are generally dried at room temperature.
- the kneading process may be followed by an extrusion step when the product resulting from the kneading is in pasty form. As soon as obtained, the dough is extruded continuously in the form of rushes, these rushes are then dried and cut.
- This process for preparing the compositions according to the invention can advantageously be implemented as and when organic waste is produced at the end of the oil extraction process, which makes it possible to prevent waste from are stored sustainably causing malodorous fermentations and / or rejected in nature. In addition it can be implemented in a rudimentary device, for example simply a concrete mixer site.
- the marginons are introduced first into the mixer and are kneaded for one minute.
- Calcium sulphate hydratable (containing the BMA (4)) is introduced little by little over a period of 4 min.
- the mixer is stopped and the granules are removed from the mixer.
- the diameters of the granules obtained are substantially between about 3 and about 25 mm.
- the marginons are introduced first into the mixer and are kneaded for one minute.
- the hydratable calcium sulfate (containing the BMA (4)) is introduced over a period of 1 min.
- the mixing lasts 5 minutes, then the mixer is stopped and the granules are removed from the mixer.
- the diameters of the granules obtained are substantially between about 1 and about 10 mm.
- Example 3 34.4 kg of pomace (dry waste of several cm), 75 kg of hydratable calcium sulfate, 0.2% of citric acid and 19 kg of water.
- the pomace is first introduced into the mixer.
- the water is then introduced into the mixer.
- the pomace and water are kneaded for 1 minute.
- the hydratable calcium sulfate (containing the retarder) is introduced over a period of 1 min.
- the mixing lasts 5 minutes, then the mixer is stopped and the granules are removed from the mixer.
