Preliminary biogas production assessment on insect frass and leachates of the organic wastes fed to larvae: A Johannesburg‐based factory case study

Energy Science & Engineering
The biomethane potential of insect frass and leachates from waste (larvae feedstock) stockpile was evaluated. Frass was derived from a black soldier fly larvae (BSFL) operation that uses a fruit and vegetable waste diet.

Biogas Production from Residues of Industrial Insect Protein Production from Black Soldier Fly Larvae Hermetia illucens (L.): An Evaluation of Different Insect Frass Samples

Processes, 2023
Insect biomass shows promise as an alternative animal feedstuff with a low climate effect. Industrial insect rearing generates residual materials, such as feed remains and insect excrements, so-called insect frass, which exhibits a high organic content. Commonly, these residues are utilized as soil amendment.

Heat Treatment and Storage of Frass From Black Soldier Fly Larvae and Yellow Mealworm Production: Compliance With EU Regulation on Microbiological Quality and Safety [PDF]

MicrobiologyOpen
Insect farming generates substantial amounts of frass, a nutrient‐rich by‐product with valorization potential as fertilizer/soil improver. Marketing is restricted by EU regulations, imposing a reference heat treatment for 1 h at 70°C to reduce the ...

An extract from the frass of swallowtail butterfly (Papilio machaon) larvae inhibits HCT116 colon cancer cell proliferation but not other cancer cell types

BMC Genomics, 2023
Background The frass of several herbivorous insect species has been utilised as natural medicines in Asia; however, the metabolite makeup and pharmaceutical activities of insect frass have yet to be investigated. Oligophagous Papilionidae insects utilise

Impact of Heat Treatment on the Microbiological Quality of Frass Originating from Black Soldier Fly Larvae (Hermetia illucens)

Insects, 2021
Since black soldier fly larvae (BSFL, Hermetia illucens) are being produced at substantial volumes, concomitantly large amounts of the resulting by-product, called frass, are generated.

Towards circularity for agro-waste: Minimal soil hazards of olive pomace bioconverted frass by insect larvae as an organic fertilizer

Journal of Environmental Management
As global populations escalate and the demand for food and feed intensifies, the generation of agri-food waste is becoming an increasingly critical issue. Addressing this challenge is crucial for optimizing food production and advancing sustainable waste management practices.

Effects of frass from larvae of black soldier fly (Hermetia illucens) and yellow mealworm (Tenebrio molitor) on growth and insect resistance in field mustard (Brassica rapa): differences between insect species and frass treatments

Entomologia Experimentalis et Applicata
AbstractFrass, a byproduct of insect rearing, has become popular for its potential use in sustainable agriculture. The rapid growth of insect production results in an increased frass output. This study examined the effects of frass as soil amendment on plant growth and resistance to insect herbivory.

Evaluation of black soldier fly larvae frass on broiler performance and meat yield, quality, and sensory characteristics. [PDF]

Poult Sci
Insect meal is an alternative feed ingredient of interest due to its nutrient content and sustainability potential. Frass (BSFLF) is produced during black soldier fly larvae meal and consists of larval excreta, exoskeleton sheddings, and leftover larval ...
