How It Works: End-to-End Carbon Removal
Carbelim has developed an integrated, end-to-end carbon removal pathway that begins with urban CO2 capture and culminates in permanent, soil-enriching biochar. Our system combines biomimetic architecture, regional waste valorization, and advanced pyrolysis to deliver verified, high-integrity Carbon Dioxide Removal (CDR) credits.
This approach addresses multiple sustainability challenges simultaneously: improving urban air quality, sequestering atmospheric carbon for centuries, regenerating degraded soils, and creating economic value from waste streams. Each stage of our process is measurable, verifiable, and designed for scale.
The Carbon Removal Pathway
Our comprehensive six-step process transforms urban CO2 emissions into permanent carbon sequestration, creating verified carbon removal credits while improving city air quality and soil health.

Step 1: Capture CO2 From Urban Atmosphere
Carbelim’s Biomimetic Facade (CBF™) systems actively remove urban CO2 and airborne pollutants, improving local air quality while generating real-time environmental data. These living walls integrate seamlessly into building architecture, transforming static structures into dynamic carbon capture systems that operate at the point of emission.
Vertical Flat Photobioreactors
Each facade module circulates microalgae cultures that absorb CO2 through photosynthesis, functioning as living carbon capture units
24/7 Air Purification
The system operates continuously, providing round-the-clock air purification and carbon sequestration regardless of time or weather
Architectural Integration
Seamless design compatibility allows installation on existing buildings without structural modifications
Steps 2-3: Biomass Production and Waste Integration
Step 2: Produce High-Value Algal Biomass
As CBF™ panels capture CO2, they cultivate nutrient-rich microalgae biomass—a valuable feedstock for carbon removal and soil regeneration pathways. The microalgae grow rapidly, fixing carbon up to 400× faster per unit area than mature trees.
This biomass represents captured atmospheric carbon in biological form, ready for conversion into permanent storage solutions. The cultivation process is optimized through AI-driven controls that monitor growth conditions and maximize carbon uptake efficiency.
Step 3: Integrate Regional Waste Streams
This algal biomass is blended with regional on-site agricultural, forestry, and organic residues, creating a sustainable feedstock for engineered biochar production. By integrating regional waste streams, we maximize resource efficiency and create value from materials that would otherwise decompose and release CO2.
This approach transforms multiple waste streams into a unified carbon removal solution, addressing both urban emissions and agricultural waste management simultaneously while reducing transportation costs and environmental impact.
Steps 4-5: Pyrolysis and Permanent Storage
Step 4: Advanced Pyrolysis
The blended material undergoes high-temperature pyrolysis, producing microalgae-enhanced, recalcitrant biochar designed for century-scale carbon stability. This thermochemical process occurs in the absence of oxygen, preventing combustion and ensuring maximum carbon retention.
- Temperature Control: Precise heating ensures optimal carbon structure and stability
- Quality Assurance: Each batch tested for carbon content and permanence
- Energy Recovery: Process heat captured for system efficiency
Step 5: Permanent Sequestration
The resulting biochar is optimized for long-duration carbon sequestration, soil revitalization, and regenerative land management. When applied to soil, biochar remains stable for centuries, effectively removing CO2 from the atmosphere permanently.
Beyond carbon storage, biochar improves soil water retention, enhances nutrient availability, and supports microbial ecosystems. This creates a regenerative cycle where carbon removal directly benefits agricultural productivity and ecosystem health.
Step 6: Generate Premium CDR Credits
Under rigorous MRV (Monitoring, Reporting & Verification) protocols, each ton of biochar delivers approximately 2.6 tons of verified CO2 removal, enabling high-integrity, premium Carbon Dioxide Removal (CDR) credits for global carbon markets. Our credits are verified under internationally recognized standards including Verra VM0044 and Puro.earth, ensuring transparency, permanence, and credibility.
