The present disclosure relates to degradation of polymer materials, such as plastic materials. More specifically, the present disclosure relates to a method for digestion of one or more plastic-comprising material by the use of at least one larva of the species selected from the group consisting of Galleria mellonella, Tenebrio molitor and Alphitobius diaperinus. The product obtained by the method is also within the inventive concept. The disclosure furthermore relates to use of said at least one larva for digestion of a plastic-comprising material.

Melanin or inorganic fertilizers are produced from fermentation leachates or from low-cost nutrient-rich solutions. The method for producing the melanin or inorganic fertilizer comprises repetitive trophic cycling in the controlled conditions of primary and secondary bioreactors. Nutrients are cycled between microorganisms such as bacteria, yeast and fungi and black soldier fly larvae, Hermetia illucens. Polysaccharides are partly converted into natural melanins or inorganic fertilizer, which are difficult to biodegrade and hence accumulate in the bioreactors. The method can employ, as a source of nutrients, leachates produced from food waste or from sugar-rich liquid waste of the food industry. These leachates can be used raw or can be augmented with low-cost sugar-rich solutions such as molasses, hydrolyzed cellulose or starch. The method is inexpensive and does not require the use of expensive chemically-defined culture media.

A method for vermicomposting includes providing an underground cell comprising a bottom, sidewalls and an open top, layering a base bedding layer at the bottom of the underground cell, layering a bottom organic waste layer on the base bedding layer, layering a stack of one (1) or more intermediate bedding layers and one (1) or more one or more intermediate organic waste layers, alternating between an intermediate bedding layer and an intermediate organic waste layer, on the bottom organic waste layer to partially form a compost heap, layering a top bedding layer on a top organic waste layer of the stack of the intermediate bedding layers and the intermediate organic waste layers to form the compost heap, watering the compost heap at a predetermined watering cycle, introducing worms to the compost heap, aerating the compost heap at a predetermined aeration cycle, and harvesting compost from the compost heap.

A device, system, and method for residue use in livestock farming, comprising a conveyor device for conveying animal excrement along a conveyor section, wherein the conveyor section has a larva-introducing portion for metering in larvae and/or larva eggs, an excrement-introducing portion for metering in animal excrement depending on one or more process parameters, and a larva-separating portion for separating the larvae, and methods for use thereof.

A closed-loop method for the continuous production of biochar and nutrients. High-moisture content feedstock and black soldier flies are placed within a breeding room to produce young black soldier fly larvae (BSFL). High-moisture content feedstock and a first portion of the young BSFL are placed within a growing room to produce leachate, mature BSFL, and frass. The mature BSFL can be separated from the frass and processed to produce dried BSFL, BSFL oil, BSFL meal, BSFL puree, or a combination thereof. A first portion of the frass undergoes pyrolysis to produce biochar and heat. The biochar can be utilized within the feedstock, to produce a frass end product, as a biochar end product, or a combination thereof. The heat can be utilized in the at least one breeding room, in the at least one growing room, to process the frass, or a combination thereof.

Provided are one or more black soldier fly (Hermetia illucens) larvae frass formulations and combinations comprising said formulations and at least one other substance including but not limited to soil amendment, fertilizer, herbicide, pesticide, fungicide, nematicide or bactericide, uses for said formulations and combinations and methods of production of said formulations.

The present disclosure relates to the production of biomass from at least one plastic polymer. More specifically, the present disclosure relates to use of a feed for production of biomass, wherein larvae of the family Pyralidae or of the family Tenebrionidae are fed on a feed comprising at least one plastic polymer, a related use of increasing pupation in a population of larva.
