Pilot Plant To Turn Co2 Into House Parts And Paving Stones

Pilot plant to turn CO2 into house parts and paving stones

https://www.newscientist.com/article/2082112-pilot-plant-to-turn-co2-into-house-parts-and-paving-stones/

Taking carbon out of the atmosphere will be crucial if we are to slow the progress of climate change. As technologies to capture carbon improve, some are already thinking about what we will do with all that CO2.

Storage in geological formations underground is one option. Better yet, what if we could make useful stuff out of it, such as biofuels, plastics or building materials?

Several initiatives to explore such ideas are under way. Canadian company Carbon Engineering is combining captured CO2 with hydrogen gas to generate synthetic gasoline at its pilot plant north of Vancouver. And Newlight Technologies, based near Los Angeles, California, is using the greenhouse gas methane to manufacture plastic products such as mobile-phone cases and chairs.

Another project, starting this week, will research ways to turn CO2 into common building materials.

A pilot plant at the University of Newcastle near Sydney, Australia, will test the commercial potential of mineral carbonation. This is a process that chemically binds CO2 with calcium- or magnesium-containing minerals to form stable materials. The plant will bind CO2 with crushed serpentinite rocks to create magnesium carbonate, which can be used to produce building and construction materials such as cement, paving stones and plasterboard....

I had that idea a while back. It's called wood! :o

Indeed, plant life has been doing this for billions of years..

Best not to worry too much about "stuff" We have it all sorted. Of course I know not about other lodges! :huh:

A bit circular, no? Unless it's being done by renewable means (e.g. growing the aforementioned wood) then the odds are it'll generate more than it uses. If it is using such means then why not use them more directly and efficiently for power directly?

The economics of these types of ventures often turn out to rely on subsidy of some kind or another.

Anything you try to do with CO2 is always going to be pretty much an academic curiosity as

A) CO2 sits in such a deep energy well that turning it into something else is always going to be energy intensive

B) There's so much CO2 in the atmosphere that you couldn't possibly make a difference by turning CO2 into 'stuff'.

The best thing to do is to probably stop cutting down trees (as has bren pointed out a tree is essentially a CO2 to chemicals factory) and reduce the amount we're burning.

I like carbon dioxide. It makes plants grow. :wacko: Obviously I don't want to live in a bag of it!

I would imagine that those in favour of it also see more taxation to support more public spending as always good. Same sort of logic.
