Abstract
A method for converting organic solid waste into humic products and the corresponding apparatus, in which a preliminary aerobic fermentation of the organic solid waste is performed, followed by a second aerobic fermentation of the organic waste in the presence of specific microorganisms in order to provide a basic precursor on which the selective metabolization occurs of specific bacterial strains to provide the humic product.
Claims3
A method for converting organic solid waste into humic products, comprising:
- 1) in a first stage, tyndallizing said organic solid waste by administering air by injecting air, such that thermophilic epiphytic microfibers naturally occurring in said organic solid waste activates exothermic biochemical reactions causing a substantial redaction of microorganisms infesting the organic solid waste to produce a first product;
- 2) in a second stage, selectively carrying out aerobic fermentation by seeding the product from the first stage with a microorganism selected from the group consisting of heterotrophic bacteria, homeofermenting bacteria and mixtures thereof, to achieve degradation and bacteria protein to form a second product rich in protein;
- 3) in a third stage, selectively carrying out aerobic fermentation by seeding the product rich in protein from the second stage with a polyphenol oxidase microorganism strain to form a third product;
- 4) in a fourth stage, selectively carrying out aerobic fermentation by seeding the product from the third stage with a microorganism selected from the group consisting of hormone-producing strains, biocidal bacteria and mixtures thereof to form a fourth product;
- and
- 5) in a fifth stage, selectively carrying out aerobic fermentation by seeding the product from the fourth stage with a microorganism selected from the group consisting of plant kingdom symbiont microorganism strains, nitrogen-fixing strains and mixtures thereof to provide said humic products.
