Carbon Removal with Enhanced Rock Weathering

ZeroEx Carbon Removal Projects

Climate action meets agriculture

According to the Intergovernmental Panel on Climate Change (IPCC), carbon sinks are essential to counteract climate change. ZeroEx has a solution:

We apply rock powder to arable land, which permanently binds CO₂ as it weathers. Additionally, the rock powder improves the soil properties. The bound CO₂ reaches the ocean in dissolved form via rivers, where it remains stably bound for several thousand years. ZeroEx thus makes an important contribution to mitigating climate change.

What ZeroEx does

We are closing the circle

We cover the entire value chain:

Starting with the exploration of quarries and agricultural land, we model the expected CO₂ sequestration potential based on the data collected here and using the latest biogeochemical models. We then implement the carbon removal projects, which requires a great deal of coordination between all partners involved, from quarries to farmers and from logistics companies to laboratories.

Before the carbon credits can be emitted, an independent and market-leading certification partner verifies every single one of our certificates to ensure that the CO₂ is really captured from the atmosphere

Benefits for farmers and the environment

Countless co-benefits besides carbon sequestration

Sustainable by-product utilization

The rock powder used is a by-product from gravel production, which would otherwise have been stockpiled exclusively.

Supplementary income for farmers

Farmers are compensated for providing access to their fields and for spreading the rock powder.

Improving soil quality

The rock powder releases iron, magnesium and other trace nutrients and loosens the soil. According to the German Fertilizer Ordinance (DüMV), the rock powder is a soil additive.

Alkaline effectiveness

The rock powder raises the pH value of the soil during weathering and thus reduces the need for liming.

Data collection

The rock and soil samples taken will generate a lot of additional data that will be shared with farmers, academic partners and other stakeholders.

Farmers

By implementing our projects as locally as possible and focusing on long-term partnerships, we promote the regional economy and create jobs.

Scientific Partners & Accelerators

Supporting sustainable developement goals

In addition to mitigating climate change (goal 13), we also want our work to make a significant contribution to achieving the United Nations' Sustainable Development Goals. These include the following goals:

  • Zero hunger: More food can be produced through additional fertilization and liming of the soil.

  • Decent work and economic growth: Through our projects, we create additional jobs under decent conditions and contribute to economic growth.

  • Industry, innovation and infrastructure: Close collaboration with science and business drives innovation across the entire field of carbon capture.

  • Responsible consumption and production: By using the by-product rock powder, natural resources are used more efficiently.

  • Life on land: Improving soil quality improves biodiversity.
