PROJECT · CEMENT & LIME
A European cement producer needed to determine how far existing technologies could reduce emissions — and when major investments in alternative fuels, clinker reduction and carbon capture should be made.
Terravia developed a portfolio-wide pathway connecting plant-level opportunities with asset cycles, infrastructure and long-term capital decisions.

AT A GLANCE
THE CHALLENGE
The producer had already improved the efficiency of its operations, but the majority of remaining emissions came from the fundamental chemistry of clinker production.
Reaching deep reductions would require multiple technologies deployed over different time horizons — while maintaining production, competitiveness and capital discipline.
THREE QUESTIONS
Identify the emissions reductions available through efficiency, alternative fuels and clinker optimisation without fundamentally changing the production system.
Evaluate the role of electrification, new materials and carbon capture in addressing emissions that conventional measures cannot eliminate.
Align major investments with kiln rebuilds, infrastructure availability and technology maturity.
PORTFOLIO BASELINE
Terravia established a common emissions and asset baseline across four integrated cement plants.
Each site differed in fuel mix, clinker intensity, equipment age, alternative-fuel capability and access to future CO₂ infrastructure.
BASELINE INCLUDED
| Plant | Annual Production | Alternative Fuels | Clinker Factor | Asset Position | Transition Readiness |
|---|---|---|---|---|---|
| Plant A | 1.8 Mt | 62% | 0.71 | Kiln rebuild approaching | High |
| Plant B | 1.4 Mt | 41% | 0.74 | Mid-life | Medium |
| Plant C | 1.1 Mt | 73% | 0.69 | Modern | High |
| Plant D | 0.9 Mt | 35% | 0.76 | Major upgrades required | Medium |

COMPARING THE LEVERS
Each intervention was evaluated against emissions impact, capital requirements, operating economics, maturity and infrastructure dependency.
| Lever | Abatement Potential | CAPEX | Economic Attractiveness | Maturity | Infrastructure Dependency |
|---|---|---|---|---|---|
| Efficiency | Low | Low | High | High | Low |
| Alternative fuels | Medium | Moderate | High | High | Medium |
| Clinker reduction | Medium | Moderate | High | High–Developing | Medium |
| Electrification | Low–Medium | Moderate | Scenario-dependent | Developing | High |
| Carbon capture | Very high | Very high | Carbon-price dependent | Developing | Very high |

TIMING THE TRANSITION
The strongest technology pathway can still fail if it ignores the investment cycle.
Terravia mapped major kiln, grinding and infrastructure decisions across the portfolio to identify the windows where transition investments could be introduced with the least disruption and stranded capital.

THE RESULT
A credible portfolio of interventions was identified across process, fuel, materials, electricity and carbon capture.
Capital requirements were connected to specific technologies, plants and investment windows.
Each site received a transition pathway reflecting its assets, emissions profile and infrastructure position.
Immediate measures were connected to major technology and infrastructure decisions extending over more than a decade.
PROJECT DELIVERABLES
Plant-level mapping of process, thermal and electrical emissions across the production portfolio.
Quantified assessment of efficiency, alternative fuels, clinker reduction, electrification and carbon capture.
Comparable analysis of technical performance, capital requirements and operating economics.
Alternative pathways showing how different technology combinations affect emissions, capital and infrastructure requirements.
Alignment of kiln cycles, electrical systems, CO₂ infrastructure and other enabling investments.
A phased portfolio programme connecting near-term action with future decision gates and major capital commitments.
