Definitions
- the invention relates generally to the field of biological treatment and recovery of organic waste.
- the invention relates to a method of treating organic waste coupling an in situ biostimulation to produce hydrolytic enzymes and hydrolysis of the recalcitrant organic waste material using these enzymes for energy recovery.
- Hydrolysis is a solid fermentation step that promotes the development of different types of microorganisms, including filamentous fungi, which produce hydrolysing exocellular enzymes.
- the production of enzymes by solid fermentation is a process known to those skilled in the art and well documented in the scientific literature 1 ' 2 ' 3 .
- US Pat. No. 7,270,751 describes a method for treating urban sludge with fungi, which comprises an oxidation step, then a step of adding an antibiotic and an oxidizing compound, and finally a step of injecting a fungus into the system. to provide treatment;
- WO 2013/163703 describes the production of a specific enzyme formula by solid fermentation, which is then extracted and used for the production of bioethanol or other products of green chemistry.
- the known methods of the state of the art use the enzymes as a solution for the hydrolysis of the recalcitrant organic material. But these enzymes are produced, extracted and used following processes involving a sequence of complex steps, which implies a high cost especially with regard to the phase of separation and filtration of the liquid medium (to recover the enzymes). In some cases, commercial enzymes are added to the medium; but this involves significant costs, sometimes inhibiting for environmental applications. These various methods are expensive and do not necessarily allow the treatment of a complex substrate.
- Substrate means, within the meaning of the present invention, indistinctly any type of waste comprising at least one organic part: household waste, green or industrial, paper or cardboard, or biomass.
- the substrates most of the time are in solid form, or comprise at least one solid part.
- complex substrate means waste of various origins containing recalcitrant organic material.
- the complex substrate may be in solid or liquid form.
- the purpose of the present invention is therefore to overcome all or part of the disadvantages of the prior art, by implementing a solid organic waste treatment process coupling an in situ biostimulation to produce hydrolytic enzymes from a substrate and hydrolysis of the recalcitrant organic material waste to be treated using these enzymes.
- the use of these enzymes produced in situ from waste (substrate) is more efficient because it is better adapted to the waste to be treated.
- biostimulation is intended to stimulate the degradation of organic waste by native microorganisms.
- Biostimulation is a biological technique that does not require the addition of selected specific microorganisms.
- biostimulation is the act of promoting the development of strains of microorganisms already present in a given medium.
- the fact of using a complex solid medium allows a variety of enzyme production that will allow better hydrolysis of the substrate that it is desired to treat because of its complex composition.
- the substrate to be treated comprises different compounds that require a mixture of enzymes to obtain optimal hydrolysis of the recalcitrant organic material. This increases the performance of the anaerobic process and therefore the production of energy.
- the fact of producing in situ the enzymes used for the hydrolysis of the waste to be treated makes it possible to simplify the treatment process and to considerably reduce the cost of operation.
- the subject of the present invention is a process for treating a first substrate that is at least partly organic and at least partially solid, comprising the following steps:
- biostimulation of the second substrate contained in the biostimulation reactor under aerobic conditions, at a temperature of between 20 ° C. and 40 ° C., a pH of between 4 and 7, a humidity of between 50% and 80% % and a residence time of between 1 and 5 days to ensure at least partial hydrolysis of the organic part of said substrate and the in-situ production of hydrolytic enzymes;
- the first and second substrates may be the same or different.
- the enzymatic production is carried out in solid medium, therefore in an environment different from that of the current large-scale production of enzymes that is carried out in a liquid medium. So a production in solid medium, that the substrates are identical or different, is more advantageous than the current modes of production.
- the enzymatic mixture produced may be more targeted. However this is not always the case, and it depends on the nature of the substrates used.
- the hydrolytic enzymes used for the hydrolysis of the substrate to be treated are produced by biostimulation of the second substrate contained in the biostimulation reactor, in an aerobic medium (step C).
- PH, temperature, and moisture controls are required in order to have a good development of hydrolytic microorganisms, especially the mycelia of the filamentous fungi from which the hydrolytic enzymes can be produced.
- filamentous fungi may advantageously belong to the group consisting of Trichoderma mushrooms. sp. Aspergillus sp. , Pleurotus sp. Penicillium sp. , and Fomitopsis sp.
- the hydrolytic enzymes thus produced are extracted by percolation (step D) of a liquid through the second substrate volume to form a first leachate enriched with hydrolytic enzymes.
- the liquid used for percolation through the volume of the second substrate may be fresh water or a recycled leachate treated by methanogenesis or by anaerobic digestion, which may be advantageously aerated before use.
- the succession of steps C and D may be repeated until the initial volume of the second substrate in the biostimulation reactor is exhausted.
- it will be decided to carry out this succession of steps C and D as a function, on the one hand, of the performance of the method according to the invention and, on the other hand, the operational cost related to the implementation of a new substrate, taking care to maintain a balance between these two constraints.
- substrate depletion means that the hydrolysable organic material of this substrate is substantially hydrolysed.
- a substrate having the organic material is largely hydrolyzed part has the advantage that its position ⁇ treatment will be limited.
- the second substrate can be used for 3 to 5 cycles of biostimulation.
- the second substrate is exhausted, it can be advantageously treated by an aerobic treatment to obtain a stabilized compost.
- a first leachate enriched in hydrolytic enzymes it is injected into at least one hydrolysis reactor containing the first substrate to be treated (step E), and then the substrate to be treated is hydrolysed by at least one partly this first leachate (step F).
- the hydrolysis step F of the first substrate to be treated can take place essentially in the solid phase.
- the hydrolysis step F can take place in a percolator and comprise the following steps:
- the second substrate once the first substrate is exhausted, the latter can be advantageously treated by an aerobic treatment to obtain a stabilized compost.
- the hydrolysis step F of the first substrate to be treated may take place essentially in the liquid phase in a hydrolytic reactor.
- the products resulting from the hydrolysis step F can be recovered by a downstream stage of methanogenesis in a methanizer, at the end of which a treated water is obtained.
- the hydrolysis step F can be carried out in an anaerobic digestion reactor for the treatment of the first substrate and the production of biogas, at the end of which one obtains a treated water.
