Technology

Zero clinker.
Zero compromise.

Our geopolymer technology eliminates the single most carbon-intensive step in cement production — and replaces it with chemistry that is stronger, more durable, and processed at ambient temperature.

The case for change

Portland's constraints
became our design brief.

Portland cement built the modern concrete industry. NuGreen was engineered around the carbon, heat, raw-material and water constraints embedded in how conventional cement is made.

Carbon

Portland constraint

Clinker production requires limestone calcination, creating process CO₂ before concrete is produced.

NuGreen design response

NuGreen eliminates Portland clinker and the associated calcination stage.

~81%Lower GWP*

Benchmark comparison

Process heat

Portland constraint

Portland clinker is produced in kilns operating at approximately 1,450 °C.

NuGreen design response

Ambient-temperature activation eliminates the Portland clinker kiln.

~57%Lower primary energy*

Benchmark comparison

Raw materials

Portland constraint

Conventional clinker production relies heavily on virgin limestone feedstock.

NuGreen design response

NuGreen uses industrial mineral resources as primary cementitious feedstock.

Fly ash + GGBFS

Virgin limestone → industrial mineral resources

How it works

From waste stream to infrastructure,
in three steps

Change the binder — not the concrete industry. A closed-loop model: industrial mineral by-products in, ultra-low-carbon infrastructure out.

01 · Collect

Waste collection

We source fly ash and ground blast-furnace slag (GBFS) from industrial facilities that would otherwise send these materials to landfills.

02 · Activate

Geopolymer activation

Our proprietary activation chemistry — incorporating a biomass-based component — creates strong aluminum-silicate bonds at ambient temperatures, eliminating the need for high-heat kilns.

03 · Avoid

CO₂ avoidance

Our process eliminates limestone calcination and high-temperature firing — removing calcination CO₂, the largest emission source in traditional cement, entirely.

Diverted 1.3t waste per ton of cement

Eliminated 0 clinker kilns — activation at ambient temperature

Avoided ~265kg CO₂e per yd³ of concrete*

Verification

Measured, audited,
and third-party verified

  • Life-cycle assessment — comprehensive cradle-to-gate LCA by third-party verifiers, following ISO 14040 / 14044.
  • Carbon market potential — NuGreen's measurable reduction in embodied carbon may support qualifying projects pursuing voluntary carbon-market or carbon-finance pathways, subject to methodology, registry and verification requirements.
  • ASTM C618 compliance — meets or exceeds all requirements for fly ash in concrete applications.
  • Independently verified environmental data — third-party verified cradle-to-gate environmental performance covering raw materials, inbound transportation and production.

Performance

Performance that moves faster.

Lower carbon is only half the story — NuGreen delivers rapid early strength and high-performance concrete for demanding applications.

What this speed means

Structural strength in 90 minutes, not days

Rapid early-strength development can shorten the time between placement and critical construction activities, subject to project-specific engineering and acceptance requirements.

  • Road repair

    Potentially shorter lane-closure windows.

  • Airports

    Potentially shorter runway and taxiway interruptions.

  • Precast

    Potentially faster mold and bed turnover.

  • Industrial

    Potentially faster return to service.

Our carbon reduction methodology

How NuGreen supports circular construction

NuGreen reduces carbon by turning industrial mineral byproducts into a high-performance cementitious binder, eliminating the Portland clinker kiln stage and supporting longer-life concrete systems within a more circular built environment.

Diagram: a four-stage material loop running clockwise from industrial byproducts, through clinker-free activation, into durable infrastructure, and on to end-of-life recovery. The return leg from recovery back to feedstock is drawn as a broken line because it is an industry pathway NuGreen does not operate.

Core material

NuGreen cementitious binder

Industrial mineral feedstocks and proprietary activation.

01

Industrial byproducts

Fly ash and slag re-enter productive use as cementitious feedstocks.

02

Clinker-free activation

Proprietary activation eliminates the Portland clinker kiln stage.

03

Durable infrastructure

Concrete is deployed in long-life infrastructure and building systems.

04

Recovery

Concrete systems can support reuse, recycled aggregates, and end-of-life material recovery.

Industry pathway — not operated by NuGreen.

Materials kept in circulation

  • Industrial byproducts utilized
  • No Portland clinker kiln stage
  • Supports long-life concrete systems

NuGreen supports circularity in the built environment by reducing clinker demand and putting industrial mineral byproducts back into productive use.

Circularity in cement and concrete includes byproduct utilization, durable service life, and end-of-life recovery pathways. NuGreen’s role is in the first two; recovery depends on construction-industry infrastructure NuGreen does not operate.
