Cement Industry Pollution Mitigation: A Comprehensive Review on Reducing Environmental and Health Impacts

Area of Science:

• Environmental Science
• Chemical Engineering
• Materials Science

Background:

• Cement production is a major source of greenhouse gas emissions, particulate matter, heavy metals, and toxic pollutants.
• These emissions degrade environmental quality and pose risks to public health.
• Existing production methods necessitate urgent mitigation strategies.

Purpose of the Study:

• To review and analyze diverse solutions for reducing pollution from cement manufacturing.
• To evaluate the efficacy of Carbon Capture, Utilization, and Storage (CCUS) in mitigating CO2 emissions.
• To examine strategies for controlling non-gaseous pollutants, including noise, soil, and water contamination.

Main Methods:

• Comprehensive literature review of pollution control technologies and mitigation strategies.
• Analysis of Carbon Capture, Utilization, and Storage (CCUS) effectiveness for CO2 reduction.
• Examination of alternative fuels (biomass, waste-derived) and their supply chain considerations.
• Assessment of noise, soil, and water pollution abatement techniques (e.g., sound barriers, phytoremediation, ZLD systems).

Main Results:

• Carbon Capture, Utilization, and Storage (CCUS) shows significant potential for CO2 reduction.
• Biomass and waste-derived fuels offer viable alternatives to fossil fuels, pending supply chain improvements.
• Various technologies exist for mitigating noise, soil contamination (e.g., cement kiln dust recycling), and water pollution (e.g., Zero Liquid Discharge).

Conclusions:

• Integrated pollution control strategies are crucial for a sustainable cement industry.
• Further research is needed on the long-term durability, scalability, and cost-effectiveness of mitigation technologies.
• Development of efficient, economically viable, and scalable industrial pollution control solutions is recommended.
