Treatment And Valorization Of Organic Matter

n this model we would select waste as manure from livestock (with special interest in poultry litter), slurry, sludge from WWTP, digestates, etc. This waste poses a continuous problem not only for the producers of this waste, but also for the managers that must collect and process them.

In this process, after the characterization of the waste, these would be introduced into the system (mixed or not with other waste), and a certain amount of larvae would be established on the waste. In this case, the larval cycle would lengthen to about 20-27 days, since the nutritive content of these feeding substrates is much lower, and the obtained larval mass will also be lower.

Waste reduction is centered around two criteria and objectives.
Volume reduction: 60-70% Reduction of pathogenic microbial load: ex. 109 ->102 *

Depends on the initial load and desired end. Final objective depends on whether it will give you further treatment.

Both objectives must be quantified and validated, since they depend on the specific mix of waste, how standard it is and its previous and subsequent handling. For example, the total lapse of time (storage,
transport, temperature, etc.) before being all mixed and the application of the larvae can have an effect on the pH, and this in turn the quantity and effectiveness of the larvae.

The technical advantage of using larvae of the species Hermetia illucens is that by making ‘ideal’ mixtures of different residues, mixtures can be processed that could not be treated in another way or at very high costs.

The competitive advantage of this treatment method is that variants can be developed for each mixture according to the needs of each specific geographical region; or legislative requirements. It opens a market that has not yet been attended to and explored.
