Carbon-Negative Concrete Production: Feasibility & Climate Impact Assessment
Carbon-Negative Concrete Production: Feasibility & Climate Impact Assessment
Client: Business Joensuu
Project period: 2025
Location: Joensuu Region, Finland
Project Overview
DME completed a feasibility study in 2025 for a carbon-negative concrete production concept in the Joensuu region, Finland.
The assignment integrated structured technology benchmarking, techno-economic assessment (TEA), and life-cycle-based (LCA-informed) GHG and carbon balance modelling to evaluate alternative production pathways and their potential to achieve net-negative CO₂e performance compared to conventional concrete production.
Technology Benchmarking and Scenario Definition
- Review and comparison of low-carbon concrete approaches
- Evaluation of technology readiness and scalability
- Assessment of input materials and supply chain suitability
- Selection of the most promising configurations for detailed modelling
Techno-Economic Assessment (TEA)
DME developed process and production system models to assess:
- Process configuration and optimisation
- Capacity and scaling potential
- CAPEX and OPEX structures
- Sensitivity to materials, energy mix, and logistics
- Economic risks and optimisation pathways
The TEA provided a structured foundation for investment and industrial development decisions.
Climate Impact and Carbon Balance Assessment
A life-cycle-based (LCA-informed) GHG assessment was conducted with clearly defined system boundaries and scenario comparisons.
The analysis quantified:
- Process and energy-related emissions
- Material substitution effects
- Carbon storage mechanisms and permanence assumptions
- Net CO₂e balance under alternative configurations
Results defined the conditions under which carbon-negative performance could be achieved.
DME’s Role
- Project leadership and coordination
- Technology benchmarking and scenario definition
- Techno-economic modelling (TEA)
- Life-cycle-based GHG and carbon balance assessment
- Scenario and sensitivity analysis
- Reporting and stakeholder presentation
Outcome
Completed in 2025, the study delivered a quantified, decision-oriented assessment of technical feasibility, economic viability, and climate performance.
It provided a robust analytical foundation for advancing low-carbon construction materials and regional industrial decarbonisation pathways.
