We want to create a world where buildings store CO₂ and contribute to a stable climate.
ecoLocked was formed from the strong desire in each of us to contribute to climate change mitigation - and to do it fast, and where it’s needed most. Knowing that the pace of industrial emission reduction is insufficient, we realized that the 1.5° target can only be reached with the additional fast scale-up of carbon removal technologies.
In September 2021, we started building eLocked with the aim of providing scalable end applications for carbon insetting in buildings, with maximum impact and performance for the construction industry. One of our core beliefs is that environmental impact and economic value can not only be reconciled but actually reinforce each other in sustainable value chains.
In 2022, we raised initial public and venture funding and opened our own laboratory and manufacturing space near Berlin. In 2023, we validated our solution on a commercial scale with multiple industry partners and released our first products for precast applications. In 2024 and 2025, we raised ~ €4 million from investors, obtained > €1 million in public funding, set up our standalone EBC-certified processing plant, obtained CE certification acc. to EN 12878 for our first CO2-negative building material, eLM Zero, and developed our Carbon-to-Concrete Platform to roll out our solution globally with local partners.
Throughout the years, we have built up a stellar team of multidisciplinary experts with a passion for climate impact and tons of concrete experience
