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

Energy Science and 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.

To treat or not to treat? Impact of hygienization on the microbiological safety of frass from black soldier fly larvae and yellow mealworm production aimed for fertilizer use [PDF]

Bioresources and Bioprocessing
Sustainable expansion of the insect farming industry requires valorization of the generated frass, a by-product with fertilizer and soil improver potential.

Upcycling Agri-Food Side-Streams via Tenebrio molitor Rearing: Growth Performance, Nutritional Composition, and Frass Quality of Larvae [PDF]

Foods
Insect bioconversion can transform agri-food side-streams into insect biomass while returning nutrients in the form of frass. This study evaluated Tenebrio molitor reared on wheat bran and on substrates in which bran was partially replaced with agri-food

Nutrient quality and maturity status of frass fertilizer from nine edible insects

Scientific Reports, 2022
Globally, there is growing interest to recycle organic waste using insect larvae into high-quality frass fertilizer through circular economy approach. This paper presents the first comparative report on the nutrient concentrations, fertilizing indices ...

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.

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

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

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.

Partially replacing synthetic fertilizer with black soldier fly (Hermetia illucens) larvae frass enhances kale (Brassica oleracea var. sabellica) production

Technology in Horticulture, 2023
A by-product of insect farming is 'frass', which is the leftover excrement that can be high in essential minerals. The frass of black soldier fly (Hermetia illucens) larvae (BSFL) is increasingly gaining interest as a soil amendment, but information is ...
