What does a BSF facility cost?

“What does a BSF facility cost?” is the wrong question. (3/6)

01 · The module

A module price is not a facility price

A supplier quoting a rearing module may be giving you an honest number.

But a rearing-module price is not a facility price.

A rearing module grows larvae. It may be the main moving part, but it is still one part.

A working site may also need waste receiving and pre-processing, nursing or purchased young larvae, breeding, a climate-controlled envelope and utilities, harvesting and separation, drying or another product route, storage, civil works, installation and commissioning.

Which of those belong on the site depends on the case. That is exactly why the first price is so easy to misunderstand.

02 · Design duty

What the site must do

Then there is design duty.

What waste enters? How much and how consistently? What product leaves: live larvae, whole dried larvae, meal, oil or frass? What climate loads must the site handle? What uptime and product quality must it deliver?

03 · Utilisation

Nameplate capacity is not processed tonnage

Then utilisation.

Nameplate capacity is not processed tonnage. Cleaning, changeovers, biological variation, maintenance, downtime and ramp-up all sit between the two. A cheap plant that runs poorly can be the expensive option per tonne.

04 · Local conditions

No two sites share a cost

Finally, local conditions.

A brownfield retrofit and a greenfield site do not share a cost. Neither do locally fabricated equipment and imported turnkey systems, or tropical and cold-climate sites.

05 · What to ask for

What to ask for instead

So what do I ask for?

Not “the facility price.”

I ask for whole-site CAPEX per unit of design throughput, and OPEX per tonne actually processed — with the same process boundary, design duty, utilisation basis, location and evidence status. Is it a model, a budget, a vendor quote or a paid cost?

Only then are two prices comparable.

06 · Solution-agnostic

Let the case decide the build

That is why I start the evaluation hardware- and solution-agnostic. I do not want a preferred box deciding the answer. A retrofit, a modular build or a centralised automated line can each be right.

And if the complete case does not close after every required system is included, the right recommendation is not to build it.

There is no honest universal price to publish here. The honest number comes after the case is defined. I will do a later post on what that case-specific calculation needs to show.
