چکیده
Будівельна промисловість є одним з лідерів щодо забруднення довкілля внаслідок вичерпування ресурсів і затрат енергії або утворення відходів. Крім того, спостерігається значна емісія від парників, кислотних газів від будівельної промисловості. Цемент належить до одного із найвикористовуваніших будівельних матеріалів у світі, а його виробництво невпинно зростає. А цементна індустрія є дуже енергомісткою. А також продукує велику кількість викидів, отруйних запахів і є дуже шумною. Пил, вуглекислота CO2, оксиди (NOx) азоту і двоокис (SO2) є основними складовими викидів від цементних заводів, що створює великі проблеми. Представлено огляд стану екологічних проблем, пов’язаних з виробництвом цементу в Європі. Ключові слова: цемент, цементна промисловість, екологія.
