Biochar is a soil amendment made typically from bio-mass through a process called pyrolysis with low-oxygen. By using a low-cost, easy-to-make biochar stove, communities can arrange to turn common waste products into biochar.
The vision behind this project is for healthy and resilient communities. This means that I prefer methods that promote local, DIY and community approach, so that it can quickly scale and adapt to different towns/cities.
Most importantly, carbon being the element behind Life has tremendous versatility. It can be used to filter water and then used as a soil amendment. Or it can be mixed to make better concrete composites for roads (asphalt) and concrete. It can improve manufacturing by making carbon fiber alloys.
Last but not least, it is done through a circular model of using waste such as wood sticks, bio-mass, paper, saw dust mills, anything with carbon, even plastics. The output heat can be captured for heating buildings and cooking stoves. The opportunities are endless.
Sizes of stove vary in function of available supply/demand dynamics. For more information, check the biochar-international.org or Ithaka International.
PS: Stockholm, Sweden has achieved this recently. If the Swedes can do it, we can learn from them and improve together!
Some guidelines for background and context
My question: what is the point of posting this on the Amsterdam "Smart City" website. The city where the local government is selling off every m2 leftover space to developers for extremely high revenues and letting them transform them into high-density urban heat sinks.
