Today Maurice Bryson from portfolio company Silicate visited the Carbon Drawdown Initiative Carbon Drawdown Initiative greenhouse and field experiments in Fürth. We share a passion for enhanced weathering science!

New soil has arrived for a re-run of our XXL lysimeter experiment. After 3 years of measurements we will dismantle 15 of the 20 large lysimeters and fill them with new soil and rock dust. 5 pots will continue for year 4 and 5.

Today, 4 years ago, we started our first enhanced weathering field trial in Fürth. Back then we had no idea that this soil would turn out to be basically useless for CDR, it is a “cation eating monster soil”. The lack of CDR signal triggered world’s largest greenhouse experiment

I’ve learned to appreciate “dirt” for all its beauty. At Carbon Drawdown Initiative, we’re currently preparing our second—bigger and better!—greenhouse experiment for enhanced weathering. One of the first necessary steps is collecting a set of soils and rock dusts. This photo shows an

This week at Carbon Drawdown Initiative we prepared 22 soils for our new greenhouse experiment for enhanced weathering. These soils are from all over Germany and from various european countries. About 15 more soils from all over the world are expected to arrive over the summer and will

Today more than 20 volunteers (most of them from Analytik Institut Rietzler GmbH) helped us to re-load our XXL lysimeter experiment for enhanced weathering in Fürth/Germany. We needed to remove 6 tons of soil from 15 large buckets - litterally by hand - while taking extensive

We reloaded the XXL Lysimeters - these buckets are measuring enhanced weathering performance since 2022! Three years ago we set up the XXL lysimeter project in Fürth Germany. We wanted to measure the enhanced weathering of basalt rock dust on soil, a promising solution to the

Our iconic dusty “Rock Farming” doormat at the entrance to our greenhouse (our weathering experiments are being rebuilt right now).

This is our scientific treasure Carbon Drawdown Initiative: more than 2,000 soil samples taken from our enhanced weathering experiments (greenhouse and outdoors) since early 2022. Thousands of hours of (wo)men-power, hundred thousands of Euros, the support of the EW science and the EW

We are rebuilding our greenhouse experiment - and make it twice as big along the way. The world's largest greenhouse experiment for enhanced weathering is leveling up! 200 of ∼500 new pots have been built last week, here is a short documentary about our work and how our pots

Nach der Dekarbonisierung brauchen wir pro Jahr 4-9 Gt CO2 negative Emissionen (IPCC). „Der Aufbau dieser neuen Industrie wird eine immense Herausforderung sein“ Wir müssen also JETZT anfangen. Carbon Drawdown Initiative forscht seit 2019 an der Verstärkung der natürlichen Verwitterung ⬇️

For me, this is the most iconic image for the power of biochar yet. It’s from a new short documentary by the Legion 44 team, produced by carbonfuture_ and Exomad Green. On the left: a corn plant from a field with untreated, nutrient-depleted soil in Colombia. On the

After only 3-4 weeks effects of rock dust amendments on plant growth are already visible! Four weeks after setup, of which the first two weeks were without any rain, we finally see germination of weeds on our XXL lysimeters which all use the same German soil. It becomes visible

Update one week later: 5 weeks after setup the germination of the weed seeds (we think it is White goosefoot/Chenopodium album) brought along by the new soils of our XXL lysimeter experiment has progressed further. The 6 controls and 6 Greenland Glacier Dust treated pots are

We’re working with the best lab in the world. Literally. At Carbon Drawdown Initiative, we partner with Qmineral, the top-ranked commercial lab for mineral quantification on Earth. How do we know they’re the best? They placed 2nd in the 2024 Reynolds Cup, the world
