Deeper exploration of 4 possible "DIY scale Carbon Capture solutions"
Let's clean up the air.
Building on the explorative research of our → DIY Carbon Capture Project this collaborative document dives deeper into 4 solutions that might work for DIY.
1. Activism
2. Enhanced Weathering
3. Carbon Gardening/Regenerative Agriculture
4. Biochar
The core idea is to connect number 2, 3 & 4 always to number 1 = activism. Small scale devices that educate people and transport political ideas. Interesting devices for activism and education.
1 Activism
"Keep it in the ground!"
Since the available technologies aren't very powerful and promising we found that the by far most potent DIY carbon capture method is… political activism. Companies have to aggressively restructure their operations and reduce their carbon footprint. Capture it before it goes into the atmosphere – at the chimney or before! This is done best politically.
Here are some questions to drill deeper on carbon activism and also a few first answers.
What are some key problems - single powerful leverages - with carbon production?
Let's find out what political demands could aim at. Problems:
What would be simple - naive - solutions to these problems?
Tools, techniques and tactics for activism? What is out there?
What inspiring examples for bottom up activism can we find?
Explanation: Sometimes there are political campaigns that combine small things with larger questions. Some campaigns make it easy to call your representative.
2 DIY Enhanced Weathering
Some rocks catch CO2 on their surface chemically. Enhanced weathering pulverises these stones to maximise their surface area and thus their capacity to bind CO2.
Can we make an enhanced weathering fitness studio? Instead of lifting weights you smash rocks?
In a nutshell: What is Enhanced Weathering? And how does it work?
Enhanced weathering or accelerated weathering refers to geoengineering approaches intended to remove carbon dioxide from the atmosphere by using of specific natural or artificially created minerals which absorb carbon dioxide and transform it in other substances through chemical reactions.
For example, Dunite is one of those materials which is rich in Olivin (Mg2SiO4), when reacted with atmospheric carbon dioxide (CO2) it forms magnesite (2MgCO3) and silica (SiO2). Here the atmospheric carbon dioxide is converted into Magnesite and silica that can be commercialized.

Where can I find the rocks needed?
If I have some of these rocks, what could be a cool and fun way to crush them? In my DIY enhanced weathering workshop/fitness studio: what tools to use, what techniques, what steps (that also don’t produce more CO2)?
What are problems with Enhanced Weathering?

Why do we not continue to explore DIY Enhanced Weathering?
Why we didn't go for the Enhanced Weathering Fitness Studio?
3 Regenerative Agriculture & Carbon Gardening
Regenerative agriculture designs biospheres and restores the soil in a way that will capture good amounts of CO2. The small version of it goes by the name of "Carbon Gardening".
How would a carbon gardening tutorial for urban environments look like? And how to connect it creatively to political activities?
In a nutshell. What is rengerative agriculture? And how does it work?
What are the key barriers for large scale regenerative agriculture?

In a nutshell. What is Carbon Gardening? How does it work?
How is it different from regenerative agriculture?
Plants & Carbon Gardening? What plants to grow? And what to think about?
Should I focus on fast growing plants? And what are fast growing plants?
Is there a minimum amount of space I need for carbon gardening? Can I do it in flowerpots?
What community actions, events and resources could be imagined that support small scale regenerative agriculture?
How could municipalities & cities support carbon gardening/regenerative agriculture for example on public greens and so on.
If I want to start right away with it? What are the 3 key articles/resources to look at with practical tips?
4 Biochar
In a nutshell. What is biochar? How to make it? How does it help with carbon capturing?
Biochar is a charcoal-like substance that’s made by burning organic material from agricultural and forestry wastes (also called biomass) in a controlled process called pyrolysis.
Pyrolysis takes place in absence of oxygen at a specific temperature range (200 to 800 degrees). When biomass is burned in absence of oxygen there is no combustion so this biomass gets converted into 3 diferent forms (liqid-bio oil,solid -biochar and gaseous-syngas). Under specific conditions bio oil yields of 60 to 70 wt% can be achived from a biomass feedstock, 15 to 25 wt% of Biochar and 10 to 15 % 0f syngas.
Biochar production is a carbon-negative process, which means that it actually reduces CO2 in the atmosphere. In the process of making biochar, the unstable carbon in decaying plant material is converted into a stable form of carbon that is then stored in the biochar.
What are the key problems to think about when aiming at DIY biochar?
How to make biochar small scale? (Interesting looking tutorials)
Why is biochar nothing to recommed for people living in cities?
How could biochar technologies make sense in urban environments or close to it?
