White papers: Gigaton, alcemy, and CemAI

Gigaton, formerly Carbon Re, makes and masters the AI-tech critical to enable autonomous plant control, reducing costs and complexity for customers and removing tons of carbon from our atmosphere, every single year.

Our Self Learning Control system unifies AI control and AI optimisation into a single system that connects directly to your DCS to autonomously control process in real time. Every control action is explainable, so your operators understand why a decision was made and the system continuously retrains as your plant changes, meaning it gets more accurate over time, not less. When plant priorities shift, Gigaton flexes it’s control strategies from ‘cost’ to ‘production’ with them. Gigaton delivers 4.2% fuel reduction and 6000 t of CO2 eliminated per plant, per year. No new equipment. No capital expenditure. No production downtime.

alcemy is a climate-tech company transforming how cement and concrete are produced. By combining advanced machine learning with deep process know-how, alcemy enables producers to cut CO2 emissions significantly while improving consistency, yield, and profitability.

Its software connects directly to existing production lines, analyzes real-time process and material data, and delivers precise quality predictions and control recommendations. This allows customers to safely reduce clinker content, optimise recipes, and stabilise strength development – without compromising on performance or standards compliance.

Working with leading cement and concrete producers, alcemy helps the industry transition from manual, experience-based decisions to data-driven, automated production. The result is lower CO2 per tonne, less waste, and more reliable products for the industry.

Founded in Berlin 8 years ago, alcemy is partnered with nearly 50% of all German concrete plants, and 45 cement plants across 17 countries. alcemy’s mission is to make low-carbon cement and concrete the industry default, enabling scalable, profitable decarbonisation of one of the world’s most emission-intensive sectors.

CemAI, Norfolk, VA is a cement-centric concern featuring digital analytic products, like its “CemAI Process Optimizer,” covering cement plants end-to-end and the “CemAI Predictive Maintenance” module. CemAI Predictive Maintenance creates value by avoiding unplanned equipment shutdowns and maximising machine life and efficiency. Combining the power of AI/ML with industry-specific expertise, CemAI Process Optimizer enables a step-change in production volumes, energy efficiency, and consistent quality output. With end-to-end data analysis in real time, CemAI delivers enhanced control at a compelling ROI.

CemAI is an affiliate of Titan Materials, which helped launch CemAI commercially over three years ago. Its predictive maintenance solution is currently installed at 21 fully integrated cement plants and CemAI’s real-time optimisation solution (RTO) is installed on over 40 raw mills, kilns and cement mills across the globe.
