Biowaste into value

Turn biowaste into feed and fertiliser

Black soldier fly (BSF) larvae recycle food and other biowaste into protein feed and fertiliser in 7–10 days, close to where the waste arises.

BSF is a real alternative to composting and biogas, and often more price-competitive, especially where no recycling route exists yet.

BSF · How it works

A biological engine for biowaste recycling

For food processors, waste companies, municipalities, campus dining, collectors and composters, and operators with many sites.

Black soldier fly larvae eat food and other biowaste and grow fast. The grown larvae become protein feed for animals, and what is left, called frass, becomes fertiliser. Biogas makes energy and composting makes a soil improver: BSF is the recycling route that gives both feed and fertiliser to sell.

From biowaste to protein feed and fertiliser. Larvae and frass can be sold in several ways, depending on local rules and demand.

  1. Two products to sell

    Larvae become protein feed and frass becomes fertiliser. Selling them locally helps pay for the recycling, so the gate fee for taking in the waste can come down.

  2. Compact and modular

    A BSF site needs little land and no large plant. It is built locally, close to the waste, and grows module by module as volumes grow.

  3. Less waste to landfill

    Biowaste becomes products instead of being dumped or burned. Compared with landfill, BSF avoids roughly 0.2–0.5 t CO₂e per tonne of biowaste, a conservative estimate.

Manna Insect · Your partner

One partner from first study to running site

Our core skill is finding where BSF pays and making it work on site. Since 2018 we have worked on BSF and biowaste cases on six continents.

We work in four steps. Assess: a free first study, then a business case on your numbers. Design and build: site, sourcing and funding design, a pilot and a project lead. Automate: Manna MIND runs the climate and equipment and logs the process. Operate: where no BSF operators exist yet, we build and lead the team with local partners. You invest more only when the step before has proven the case.

Making a product is only half of the business. Our network covers suppliers, buyers, partners and team training, and we help build the local market for larvae and frass.

A real alternative

Which route fits your biowaste?

Most organisations already know composting and biogas. BSF is the newer option, and in many cases it can solve the cost problem the alternatives leave open.

  • Composting

    Low entry cost, but it needs a lot of land and makes a low-value soil product. It works best where gate fees are high.

  • Black soldier fly (BSF)

    Makes protein feed and fertiliser to sell. Compact, modular and able to work without subsidies. It works best where feed and fertiliser sell locally.

  • Biogas

    Makes energy from wet waste, but needs large, costly plants and often subsidies. It works best at large scale.

Zero-cost bioconversion is possible when larvae and frass have real buyers, the site is free or low-cost and the local numbers check out. BSF does not fit every case, and that is why the first analysis is free: tell us about the biowaste and get a first calculation at your scale.
