Particularly exciting given that concrete makes up close to 5% of global CO2 emissions.

- Nasrudith 8y agoDoesn't the CO2 eventually return to the concrete when it cures and hardens making it sorta the reverse of crops in long term neutrality? (Generates CO2 on creation but retrieves it eventually as opposes to capturing but returning eventually.)
- foxyv 8y agoMost of the CO2 produced is the energy used to process it. Concrete is very energy intensive.
- Nasrudith 8y agoHuh I thought it was the Calcium Carbonate needing to be broken free. I guess that is more good news for clean energy - get that down (not a trivial task) and you only have to worry about that component.
- greenbee1981 8y agoBamboo can be used to hold a lot of CO2 and store it in long term products. The fiber is also being used in a concrete mix to reduce the carbon footprint and reduce weight etc.. Bamboo plantations can be great for the planet. www.ecoplanetbambooplantations.com
- goda90 8y agoI'm not sure hempcrete would be able to replace most concrete since it's compressive strength is 1/20th of concrete, but it'll certainly help in some applications because it has its own advantages.
- CuriouslyC 8y agoHempcrete makes a great component of alternative homes, where environmental impact and low cost are important and structural strength/long term durability are less of an issue.
