Turning buildings into carbon sinks.

We provide a turnkey solution for the construction industry to build with climate-neutral concrete.

What we do

ecoLocked is using carbon-negative materials to create an emission-free built environment. We develop new recipes for concrete and replace some of the traditional emission-intensive ingredients with biocarbon, a carbon-rich material obtained from  biomass residue. The result: a concrete that is not only sustainable but also more insulating, durable, lighter, pollutant-absorbing and with many other features that can be customized to different applications.

At the heart of our work: ecoLocked Materials – our biocarbon-based admix materials for climate-positive concrete.

Why that is important

Concrete is the second-most consumed material on earth and its use is expected to double between today and 2060. Already today, the production of cement clinker, the key ingredient of concrete, is responsible for 8% of global greenhouse gas emissions.

While the construction sector has committed to reaching net zero by 2050, it is lacking scalable approaches to achieve that goal. Even if all currently available technologies could be applied jointly and at scale, only a 50-60% emission reduction would be realized.

Meanwhile, the world is in need of carbon removal at a gigaton scale. Biocarbon production is among the most cost-efficient and mature removal technologies, and it returns a material that is versatile and combines many useful properties for construction. Therefore, we have dedicated our venture to developing value-added uses of biocarbon in building materials – and can provide the construction sector with scalable and affordable decarbonization solutions!

How it works

Our admix materials are seamlessly integrated with existing production processes and do not require significant capital investments. Moreover, they are complementary with many other concrete decarbonization approaches, allowing to jointly maximize positive climate impact.

ecoLocked Materials decarbonize the construction sector in three ways:

Green concrete


We permanently store sequestered CO2 in the built environment, compensating hard-to-abate emissions from cement production

Lifetime emission reduction

Our admixes enhance buildings’ energy efficiency and have the potential to accelerate  lifetime carbon sequestration

Direct emission reduction

Our recipes reduce the need for CO2-intensive ingredients like cement clinker

ecoLocked Materials:
Our solution for climate-positive concrete

ecoLocked Materials are biocarbon-based concrete admix materials designed to reduce embodied CO2 and turn buildings into stable carbon sinks.

Their integration is simple and happens directly at the concrete plant or at the site of a construction project: Conventional inputs like cement are partially substituted with ecoLocked Materials based on our customized recipes, which minimize CO2 and maximize functional performance according to the specific requirements of a project.

We are building a portfolio of products to enable climate-friendly concrete across multiple applications. In 2023, we will run the first commercial pilots in locations across Europe. Stay tuned for further information – and reach out if you want to decarbonize concrete together!

Our Mission

Providing scalable end applications for biochar insetting in the construction industry with maximum impact and performance.

ecoLocked was formed from the strong desire in each of us to contribute to climate action – and to do it fast. Knowing that the pace of industrial emission reduction is insufficient, we quickly realized that the 1.5° target can only be reached with the additional fast scale-up of carbon removal technologies.

And we are convinced that biocarbon production is the most powerful of them all. It can be deployed at scale today and

  • is incredibly effective and cost-efficient thanks to the use of residue inputs, low operating costs, and the recycling of excess pyrolysis gas
  • returns a material with tremendous potential in a range of industries, including agriculture, water filtration, and last but not least: construction

In September 2021, we started building ecoLocked with the aim to provide a scalable solution for the decarbonization of the built environment and at the same time enable carbon removal at scale. We have not slowed down since and are proud to present our diverse team of multidisciplinary experts and climate enthusiasts!
