The construction sector is a central obstacle to Europe’s climate ambitions. Responsible for up to 40% of global greenhouse gas emissions, it remains one of the hardest sectors to decarbonize, largely due to the embodied emissions of construction materials. Despite regulatory pressure under the European Green Deal and the Paris Agreement, the EU is currently off track to meet its 2030 and 2050 climate targets. At the same time, Europe faces growing demand for housing and infrastructure, making the continued use of carbon-intensive materials such as cement and clay bricks increasingly unsustainable. In parallel, Europe generates vast quantities of forest and agricultural side streams, particularly lignin from pulp and bioethanol production. These carbon-rich resources are largely underutilized and typically incinerated for low-value energy, releasing billions of tones of CO2 annually. Existing technologies have failed to transform these side streams into high-value, durable and scalable products, resulting in lost economic and climate mitigation potential.
The Elementic project addresses this structural gap by developing a carbon-negative construction material that directly substitutes conventional masonry products. Elementic converts lignin-rich biomass residues into durable construction products, such as bricks, panels, and façade elements that store approximately 5 kg of atmospheric CO2 per kilogram of material, effectively transforming buildings into long-term carbon storage structures rather than emission sources. Unlike most low-carbon alternatives, Elementic is a mono-material, fully recyclable, mechanically competitive, fire-safe, and designed for compatibility with existing construction practices.
The project’s core objective is to advance Elementic from TRL 5 to TRL 9, completing industrial piloting, certification, real-world demonstration, and market entry. Deployment focuses on multiple application, from façade applications, to interior panels - where climate impact is immediate and adoption barriers are low. Replacing a conventional façade with Elementic can fully negate the embedded CO2 footprint of an average residential building, delivering a net-negative lifecycle outcome. At scale, Elementic offers system-level impact: reducing construction emissions, unlocking high-value uses for biomass side streams, strengthening European industrial autonomy, and supporting circular-economy-driven regulation. In doing so, Elementic provides a credible pathway for reconciling Europe’s need to build with its obligation to decarbonize, turning cities into carbon sinks rather than sources.
