Organic Waste

Stop selling insect protein. Start solving a waste problem.

Food manufacturers pay to have production leftovers removed. BSF farms can compete for that service, use eligible by-products as feed, and sell the larvae.

Profitable Black Soldier Fly Farming: an operator manual from a working plant

What is in the English BSF operating manual, who it is for, and the thesis behind it: smaller plants close to waste, and unit economics before scale.

BSF Substrate Formulation: Ash Is Now a Performance Variable

A new Waste Management meta-analysis puts ash beside protein and fat in BSFL process control, with useful thresholds for substrate pilots.

Fishmeal Price Spikes Are Not a BSF Strategy

Innovafeed's warning: fishmeal spikes are not a BSF strategy. Scarcity opens the trial. 2% attractant or 5–10% health-window use has to hold after prices fall.

El Niño, Aquafeed Resilience and BSF Qualification

The next El Niño is an aquafeed resilience test. BSF only helps if it is already qualified: specified, trialled and contractable before the shock.

Peru Anchoveta Fishing Ban: Feed Security and BSF

Peru's 2026 anchoveta ban and fishmeal near US$3,000/t are a feed-security shock. BSF is an alternative, not a tonne-for-tonne fishmeal replacement.

Feed Security and Input Sovereignty: Aquaculture Insect Protein

Aquaculture feed security is input sovereignty: 2026 fish oil at a decade low, insect meal up to 20% in salmon and trout, and EU substrate rules still tight.

EU Insect Feedstock and Substrate Rules Are the Bottleneck

The EU opened insect PAP for aqua, poultry and pig feed. Catering waste, manure and meat-and-bone meal stay banned. Substrate access is still the bottleneck.

BSF Fractions in Rainbow Trout: Oil, Chitin, Full-Fat and Defatted Meal

Riesenbach et al. tested BSF full-fat meal, defatted meal, oil and chitin in rainbow trout. 4% oil and 1% chitin helped in low-soy diets; high-soy did not.

The Rainbow Trout Soybean Trial Makes the Best Case for Low-Inclusion BSF

Ma et al. tested 2.5% and 5% whole-body or defatted BSFL in high-soy rainbow trout diets. The result is one of the clearest arguments for selling BSF as a complementary functional ingredient rather than only as fishmeal replacement.

BSF as a Functional Aquafeed Additive

Onomu and Okuthe's 2024 review: position BSF as a functional aquafeed additive for health, resilience and feed efficiency, not crude protein.

Fishmeal Output Fell 28% in Q1 2026: BSF in Aquafeed

Global fishmeal output fell 28% in Q1 2026 (IFFO). That tightness strengthens BSF in aquafeed as a planned ingredient, not a crude fishmeal substitute.

Functional Feed Additives Are the Better Frame for BSF in Aquafeeds

Aquaculture Magazine's review of functional feed additives is a useful prompt for the insect sector: BSFL meal may be more valuable as a targeted gut, immune and diet-stability tool than as a blunt fishmeal replacement story.

BSFL Minerals Can Be Steered: Brewery Spent Grains Outperformed

Minerals in BSFL can be steered via substrate. A 2026 paper found brewery spent grains outperformed conventional feed for zinc and manganese accumulation.
