Research Progress on Low-Carbon Technologies and Assessment Methods in Cement Industry

Abstract

As one of the pillar industries for social development and economic construction, cement manufacture is energy and carbon-intensive, whose greenhouse gas (GHG) emissions account for more than 6% of total global man-made GHG emission annually. With the growing attention on the problem of global warming, researching and promoting low-carbon manufacturing technologies to reduce GHG emissions have become the main trend in the development of cement industry under the new era. This article sorted out the low-carbon technologies for cement production reported in recent years, introduced the mainstream methods of GHG accounting and assessment such as life cycle assessment (LCA) and carbon footprint analysis (CFA), meanwhile reviewed the articles in the field of low-carbon technology and assessment methods in cement production, moreover, discussed the merits and demerits of various assessment methods and applicable fields, in order to provide suggestions and supports for low-carbon transformation of cement industry.
