Custom icon vocabulary built for Advanced Circular Manufacturing. Schematic precision over generic SaaS aesthetics — every icon reads like it belongs on an engineering drawing, not a dashboard.
The rule: If a Carbotura icon could appear in a generic SaaS product unchanged, it is wrong. Every icon should feel like it was drawn for a feedstock processing facility, a Circular Supply Agreement, or a RevCon™ data stream — not a CRM.
1.5px is the governing weight at 24px. Deviation requires justification. Heavier strokes signal structural importance; lighter strokes signal secondary information.
Icons representing the core ACM technology stack — reactor, feedstock, RevCon™ streams, modules. Drawn from P&ID conventions adapted to the Carbotura context.
Hydrogen Separation is a stage, not a product. This set mixes process steps with sellable outputs, and that makes one icon dangerous: a bare Hydrogen icon placed between Renewable Graphite and Renewable Metals reads as a product line. Carbotura does not sell hydrogen — energy is Island Mode, internal only.
So the icon is labelled Hydrogen Separation, which is what it actually depicts: a named stage of Regenesis MAX™, alongside carbon activation at 1,800°C, graphitization at 3,000°C, metals purification and rare-earth extraction. Never relabel it to the bare element, and never place it in an outputs or revenue lineup.
The sellable outputs are synthetic graphite, graphene compounds, recovered minerals and net-positive ultrapure water. If a layout needs a product icon, use one of those — the fix is choosing the right icon, not restyling this one.
CSA, Beneficiation Fee, Circular Royalty™, engagement stages, community benefit. The commercial and contractual layer of the ACM relationship.
Landfill, diversion, emissions, compliance, certification. The regulatory and environmental context Carbotura operates within and improves.
Navigation, status, data, interaction. These are the standard UI icons adapted to Carbotura's stroke weight and visual language.
The same icon across the five approved sizes. Stroke weight holds at 1.5px for 16–32px. Increase to 1.75–2px for 48px and above.
Icons inherit color from context via currentColor. Apply brand color directly to the parent element or the SVG itself. Never hardcode color inside the SVG path.
Custom icons cover the Carbotura-specific vocabulary. For generic UI actions (close, search, sort, pagination), approved third-party icons may be used — with adjustments.

The test: Would this icon appear in a Salesforce or Notion UI unchanged? If yes, it needs a custom replacement for any Carbotura-specific concept. Generic actions (close, sort, chevron, search) may use Lucide. Anything representing ACM process, commercial structure, or environmental data must use the Carbotura custom set.
