Biological waste treatment expertsAbout biological waste treatment
Insects do a third of the work on Halo, and black soldier fly larvae appear in three entries alone, converting citrus peel, apple pomace and soybean waste into protein and lipid. Microbial and fungal routes make up the rest, ending in fertilizer, fatty acids or a living soil amendment. On Halo it spans three groups: insects eating the waste, microbial and fungal conversion, and collection and handling.
Stage of development. Work on biological waste treatment on Halo comes mostly from university programs. 35% of the solutions are in market. Sponsored research and co-development are the usual partnering routes, and about 33% of the solutions that state terms offer licensing.
Three trends in biological waste treatment on Halo
Black soldier fly, three times. Two entries run the larvae on citrus peel and apple pomace, one of them on site and taking the feedstock wet, and a third uses the frass left behind as a banana nursery biostimulant. A fourth insect platform works soybean waste into pet food. The organism handles moisture, acidity and variability that a reactor would need conditioning for.
The output decides the organism. Protein and lipid from larvae, fertilizer from fungal fermentation, butyric and caproic acids from arrested anaerobic digestion, biogas from co-digestion, a living soil amendment from an enriched consortium. Each entry picks the biology that ends where its buyer is, and the feedstock is frequently the same peel.
The acid in the peel decides the process. Citrus peel is wet and acidic, and three entries answer that directly. One buffers it with manure so it can be co-digested to biogas. One holds the digestion at low pH on purpose and takes butyric and caproic acids off it. One enriches a site-adapted microbial consortium on the peel where it already sits, so nothing has to be moved.

Frequently asked questions
What is biological waste treatment?
Biological waste treatment covers using living organisms to break down a waste stream. It spans insect bioconversion of food and agricultural residues, microbial and fungal conversion into fertilizer, fatty acids or a soil amendment, and the collection and handling that gets the waste to the organism. Waste processors, food manufacturers and agricultural operations are the buyers.
What are examples of biological waste treatment?
