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.
Bacillus cereus in BSF Rearing: Larvae Are Not a Sanitation Step
A new Food Microbiology paper reports that Bacillus cereus persisted through Hermetia illucens rearing, with larvae and frass requiring post-rearing treatment even when authorized substrates were used.
Innovafeed €51M Raise: What the Nesle Scale-Up Means for BSF
Innovafeed raised €51 million as it concentrates BSF production at Nesle, folds Gouzeaucourt in, and tests whether industrial scale can turn into margin.
2024–2025 BSF Failures and Lessons
2024–2025 BSF failures: ENORM bankrupt, Inseco exited, Ÿnsect and Agronutris in court. The lesson is cost, regulation, offtake and cash, not biology.
Ÿnsect Bankruptcy: Judicial Liquidation After €600 Million
Ÿnsect entered judicial liquidation on 4 December 2025 at Évry. About €600 million raised. 2022: ~€568,000 revenue against ~€90 million losses.
