But to capture from the air the amount of carbon dioxide emitted by, say, a 1,000 - megawatt coal power plant, it would require air - sucking machinery about 30 feet in height and 18 miles in length, according to a study by the American Physical Society, as well as huge collection facilities and a network of equipment to transport and
store the waste underground.

Some forms of carbon removal are also subject to significant debate, such as whether bioenergy with carbon capture and storage (BECCS)-- which involves burning biomass like crop
wastes for energy and capturing and
storing the carbon emissions
underground in geological formations — can be truly sustainable at a large scale given competing needs for land, among other concerns.
Liquid
wastes containing radioactive caesium and strontium salts were
