Ten instruments put ten concrete questions to our own numbers: how much material for 300,000 t of rebar, which route emits least, how much electricity hour by hour.

Each tool rests on a tested model, shows its assumptions and their sources, and produces a link you can share.

Method
How an instrument is built
A tool is only worth what it lets you check. All ten instruments follow the same contract, from calculation to display.
- A pure, tested model
- Every calculation is a function independent of the interface, checked by automated tests: conservation of mass in the value chain, monotonicity, exact return to the values published by worldsteel, daily energy equal to annual energy.
- Visible assumptions
- Every coefficient appears in a table with its value, range, status and source. Default values reproduce the RC-1 reference configuration used throughout the site, so tools and pages never contradict each other.
- A plain-language result
- A sentence answers the question and updates with every change; screen readers announce it. Key figures, a chart and an equivalent table come with it, together with a method note.
- A link that keeps your settings
- Inputs are written into the page address: copy the link to share exactly your case, print the page, or export the result as CSV.
What the tools are not: commercial offers, engineering studies or tax advice. Their results are indicative; they will be replaced by verified measurements once the plant operates.
Vocabulary
Four statuses, the same everywhere
- Sourced
- A figure published by an identified, dated source: worldsteel, the International Energy Agency, INS Cameroun, ARSEL, the Port Autonome de Kribi.
- Derived
- A result computed from sourced figures by a stated method, such as Phase 1 annual electricity or the ore required.
- Assumption
- A planning value chosen within a published range, to be confirmed by engineering, permits or operation.
- Illustrative
- A value chosen to make the tool readable; it does not describe the project and can be changed freely.
