FIELD: process engineering.
SUBSTANCE: invention relates to production of cement and quick lime. In production of product, in particular, cement and/or quick lime from carbonate-bearing materials, generated carbon dioxide is not released in atmosphere but, instead, not necessarily, after conversion into carbon monoxide, is converted into sodium formate to be converted into sodium oxalate. Obtained sodium oxalate reacts with calcium hydroxide to be converted into calcium oxalate to be used as an additive to concrete mix or otherwise.
EFFECT: decreased emission of carbon dioxide.
