Air Quality Management

Principles

The production of limestone and lime involves grinding and crushing limestone, as well as processing calcium carbonate. This process generates dust, smoke, and gases that can contribute to air pollution and degrade air quality. To mitigate these effects, policies and guidelines have been established to minimize the impact and implement measures aimed at controlling and preventing dust-related issues that may affect nearby communities.

The Company has established the following management guidelines:

1. Regulatory Compliance:

• • Adhere to relevant local, national, and international environmental laws and regulations.
  • Apply best practices and standards for managing air quality

2. Pollution Prevention:

• • Prioritize pollution prevention at the source by altering or creating manufacturing processes that utilize materials to lessen impacts and enhance operational efficiency.
  • Encourage the adoption of clean technologies and renewable energy options.

  • Collaborate with communities, government bodies, and other organizations on projects aimed at improving air quality.

6. Employee Engagement:

• • Provide education and training for employees on environmental policies and practices.
  • Encourage employee involvement in environmental initiatives and ongoing improvement efforts

Dust and Gas Control Measures:

• • Dust and gas control system: Implement a system to minimize dust and gas emissions from production activities.
  • Closed system: Utilize a closed system for material storage management to prevent dust dispersion.
  • Water spraying: Employ water spraying methods to control dust during material handling and transport.
  • Green buffer zone: Establish a green buffer zone by planting trees and vegetation around the facility to mitigate dust.
  • Regular cleaning: Ensure equipment, vehicles, and facilities are kept clean to avoid dust buildup.
  • Inspection and reporting: Continuously assess air quality and provide reports to relevant authorities.

Noise controls and mitigations:

The production process will involve sources of noise, such as the large fan system (Blower System), which is housed within a closed concrete structure. Other noise sources will not include heavy machinery but will involve control devices used in the process. These control devices are implemented to mitigate noise pollution and ensure compliance with noise control regulations.

• • Noise control system: Implement a system designed to minimize noise emissions during production.
  • Use of noise-dampening materials: Incorporate materials that reduce noise in both production and construction activities.
  • Equipment upkeep: Regularly clean and maintain equipment to minimize noise generation.
  • Monitoring and reporting: Routinely assess noise levels and communicate findings to the appropriate authorities.

Wastewater quality management without discharge :

• • An internal wastewater treatment system that utilizes water circulation for coagulation and reuse
  • The use of lime in the coagulation process, which is an eco-friendly approach to wastewater treatment.
  • Equipment upkeep: Ensure cleanliness and proper maintenance of treatment system equipment, water pumps, and related components.
  • Ongoing inspection and reporting: Regularly monitor wastewater quality and communicate findings to the appropriate authorities.

Water utilization in the production process involves:

Spraying water to clean stones prior to their introduction into the kiln for burning.

Water management system:

• • A pond and piping system are in place to redirect used water back to the storage tank.
  • Used water will settle in the tank.
  • Water is recycled following the sedimentation process.

Sludge in the pond:

• • mud from the stone washing and cement dust from production activities.
  • Dredging and removal for various uses, such as:
    • Leveling the factory grounds
    • Donating to temples, schools, and local communities.
    • used for land filling

Wastewater Quality Monitoring:

Measurement operations yield results that meet the specified standards, except for pH, which ranges from 5.5 to 9.0.

Remark:

The water properties used in the company's system showed a pH value between 11 and 13 during inspection, indicating high alkalinity. This is due to the use of lime products, which exhibit high alkalinity when water circulates within the production process. The water quality measured reflects this high alkalinity. However, since the factory's wastewater system operates as a closed-loop system and does not discharge into the environment, it does not pose any external risks.

Thermal Management:

The thermal produced during the manufacturing process, especially during calcination, does not affect the environment since the kilns function as a closed system with brick insulation to contain the heat. Key points are monitored to assess temperature and heat values that might have an impact.

Additionally, there is a machine process control system utilizing PLC technology and visualization. This allows for parameter adjustments to optimize the machine's operation, particularly in controlling the combustion process in the lime kiln. The system can regulate oxygen levels and temperature to ensure efficient combustion, thereby minimizing carbon dioxide (CO2) emissions produced when limestone is heated above 900 degrees Celsius (CaCO3 + Heat = CaO + SO2).
