Innovative CO2 Extraction: Using Old Wood and LEGO-Like Technology

Start-up Graphyte, incubated by Breakthrough Energy Ventures, claims to have developed a simple and cost-effective method for removing carbon dioxide (CO2) from the atmosphere. The company uses plant waste, such as wood chips and rice hulls, to create carbon-laden blocks that can be buried underground for hundreds of years. This approach could store a ton of CO2 for around $100, a significant milestone in affordable carbon removal. While other methods like direct air capture are more complex and expensive, Graphyte's plant-based approach offers a simpler and potentially more scalable solution to combat climate change.
