Cement Manufacturing Enforcement Initiative US EPA

The cement manufacturing industry was an EPA New Source Review/Prevention of Significant Deterioration (NSR/PSD) national enforcement initiative in fiscal years 2008-2010 and was continued as a Reducing Air Pollution from the Largest Sources national enforcement initiative for fiscal years 2011-2013. The cement sector is the third largest industrial source of pollution, emitting more than

Environmental impact of cement production: detail of the

Mar 01, 2010· 1. Introduction. The Portland cement manufacturing industry is under close scrutiny these days because of the large volumes of CO 2 emitted. Actually this industrial sector is thought to represent 5–7% of the total CO 2 anthropogenic emissions (Hendricks et al., 1998, Humphreys and Mahasenan, 2002).Therefore numerous studies have been done to evaluate CO 2 emissions and

Environmental Impact of Ordinary Portland Cement

There are lots of environmental impacts of Cement on our ecology. One of the major problems is emission of CO2 from the Cement industry. It is found that world yearly 1.6 billion tons production of cement covers 7% of carbon dioxide's yearly production. As CO2 is harmful for human health and also for the wild life. It causes many respiratory problems like asthma, bronchitis, and nasal infections.

Precast Concrete Manufacturing and the Environment

Precast concrete manufacturing has an intrinsic environmental advantage compared with constructing similar products at a job site. Although it may be something we take for granted, this advantage has always been an important component of any precast product, and in today’s environmentally conscious world it is becoming a more important value
