TECHNOLOGY FOCUS - BIOLOGY - Preferred components: The fibrous vegetable material (10-90 (preferably 20-40) wt. %) of (II): is alfalfa (preferred), hemp, linen residue, beet crown or leguminous plants of horse bean. The binding agent is: of natural origin (which is a mixture of starch and proteins) or synthetic origin. The natural binding agent (25-47 wt. %) is vegetables (rice, potatoes, manioc, corn, wheat, barley, oats, hop or tapioca, preferably cereal flour), which give starchy compound. (II) further comprises a hydrosoluble carbonated binding agent (0-5 wt. %) (natural hydro-soluble polymer (vegetable juices which is produced by alfalfa or other vegetables comprising graminaceae, polysaccharides product from molasses, cane sugar and/or sugar beet, where the products results from a fractionation of vegetable juices in particular hydrolysate and serums) of natural origin. (II) comprises a binding agent of synthetic origin in total or partial substitution of the natural binding agents. The binding agent of synthetic origin (0-40 wt. %) is preferably a polyvinyl alcohol. The plasticizer (polyols, preferably glycerol, sorbitol, ethylene glycol, diethylene glycol, propylene glycol, adonitol, dithioerythritol, dithiothreitol, galactitol, inositol, mannitol and/or xylitol) (1-30, preferably 3-20 wt. %) of hydrosoluble (II) is a biodegradable hydrosoluble organic compound of natural or synthetic origin. In the product, mineral charges (clay (preferably kaolinite or montmorillonite), talcs, silicones, calcium carbonates or titanium oxide) (0-15 (preferably 0-10) wt. %) and lubricating agent (zinc stearate or magnesium stearate) (0.5-5, preferably 0.5-1.5 wt. %) are added to (II). To (II), other additives of the group constituting nutriments and additives of bacterial increase (pectin, yeast extracts, cellulose and hemicellulose, polysaccharides, enzymes, amino acids or vitamins), amino acids, enzymes, mineral salts (nitrates and/or phosphates and/or sulfates of: ammonium, potassium, magnesium, calcium, sodium, manganese, molybdenum, iron, copper or zinc) or ammonia salts are added. (II) contains 5-30 wt. % of water. The cultures within (A) are aerobic strains (preferably bacteria, yeasts and fungi of the cycle of nitrogen and carbon). The bacteria, yeasts and fungi in the form of aqueous suspension with their nutritive medium in the internal filling is 0.5-20 (1-10) wt.% in (B). In (I), at least an amino acid of the nutritive substrate of the formulated internal filling is chosen from a group of 21 amino acids. The quantity of amino acid in the nutritive substrate is 1-10 wt. %. The nutritive substrate (20-70 wt. %) of the formulated internal filling further contains: mineral salts (nitric and/or phosphates and/or sulfates of: ammonia, potassium, magnesium, calcium, sodium, manganese, molybdenum, iron, copper or zinc) and/or ammonia salts; and nutriments and additives of bacterial growth. The viscosity-modifying agent (20-70 wt. %) in the formulated internal filling is of mineral (clay (preferably kaolinite or montmorillonite), calcium carbonate or magnesium carbonate) or organic origin (glutamates, carrageenan or alginate). The formulated internal filling is 5-35 wt. %. The aerobic strains in the internal filling are of family Micrococcaceae, Lactobacillaceae, Bacillaceae, Nesseriaceae, Enterobacteriaceae, Azotobacteriaceae, Rhizobiaceae, Nitrobacteriaceae, Thiobacteriaceae, Pseudomonadaceae (like bacterias), Pseudomonadales, Pseudomonas, Nitrosomonas, Nitrobacter, Thiobacillus, Vibrio, Acetobacter, Azotobacteriacae: Azotobacter, Beijerinckia Achromobacteriacae: Achromobacter, Flavobacterium Enterobacteriacae: Aerobacter, Serratia Lactobacillacaes: Lactobacillus, Corynebacteriacae: Arthrobacter Bacillacae: Bacillus, of the actinomycetes: Actinomycetacae: Nocardia, Pseudonocardia, of the mushrooms: Mucoralae: Rhizopus, Protoascomycetae (yeasts), Candida, Torula, Rhodotorula, Cryptococcus, Torulopsis, Euascomycetes (moulds), or Aspergillus. The bacteria, fungi, yeast aerobic strains are in a culture (having a concentration preferably 107-1010 ufc/ml).    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preparation (claimed): Preparation of (I) comprises: drying and optionally crushing by dehydration, and compacting a vegetable material; mixing the fibrous vegetable material with binding agent, plasticizer and optionally additives to give (A); preparing a formulation (which plays the role of a formulated internal filling) comprising a bacterial, fungi and/or yeast colony in mixture with a nutritive substrate (containing at least an amino acid and a viscosity modifying agent to be conditioned in (A); compounding, plastifying, and forming (II) by the techniques of compounding extrusion and tube co-extrusion, which is profiled and multilayered; compounding, plastifying, and forming of (II) by means of techniques (preferably compounding extrusion); injecting/pumping of the formulation (which plays the role of a formulated internal filling within a profiled, multilayered tube formed during co-extrusion to make a profiled, multilayered tube containing the filling); and air-tight closing of (A) by a pressure exerted on the ends of the profiled and filled tube, or on the sides of the filled multilayer and cutting of the filled layers thus formed. EXAMPLE - Typical biodegradable composition comprises (%): alfalfa (37), wheat flour (34), glycerol (12), silica (0.25), magnesium stearate (0.97) and water (15.78).
