Management policy

We comply with environmental regulations, commitments and strive to reduce and prevent pollution, mitigate potential risks in operations, and continuously improve.
We conduct regular and irregular inspections to review our compliance with environmental regulations and propose corresponding improvement measures for non-compliance.

Management goal

We conduct daily equipment inspections and monthly factory environment inspections by 5S teams to prevent pollution. We prevent the leakage and volatilization of harmful substances or gases and reduce the emission of particulate matter and spills of PVC resin silo.

The main air pollutants emitted from the processes of each plant of CGPC include sulfur oxides (SOx), nitrogen oxides (NOx), volatile organic compounds (VOCs), and particulate pollutants (Total Suspended Particulate, TSP).

In order to effectively control air pollutants, each plant of CGPC regularly conducts air pollutant monitoring and reports to the competent authority on schedule. It also obtains the fixed pollution source installation and operation permit in accordance with the law and has air pollution dedicated personnel and agents to manage it. CGPC (Toufen Main Plant) built a new Activated carbon Fluidized Bed Technology for VOCs Adsorption and Control in 2022, to reduce VOCs and mitigate greenhouse gas emissions.

Note:

In 2021, due to the increase in production, the number of days in which the boiler is in operation also increased, resulting in an increase in NOx and VOCs emissions.

Since 2020, CGPCP's TSP has reduced due to that clean water was added to the venturi scrubber to wash the particulates away, so the TSP emissions have been reduced.

The construction of pollution prevention equipment at CGPC Main plant was completed in 2022, and a natural gas boiler was added in October 2023 to gradually reduce the use of coal-fired boilers.

Due to the high emission intensity found by the flue test results of TVCM in 2023, the recent improvement of the storage tank (T6030 fixed tank instead of a pressure tank) is expected to reduce VOCs by 3-4 metric tonnes/year.

In the third quarter of 2023, in response to regulatory updates, CGPCP needs to calculate the VCM emissions of individual species and the cost plus the increase in VOC emissions due to increased production capacity. The stripping tower and venturi scrubbers will be re-reviewed and improved later.

The description of effeteness for activated carbon Fluidized Bed Technology for VOCs Adsorption and Control

CGPC's leather plant promotes “circular economy, cost reduction, and employee work environment health and well-being”.

Abnormal leaks and emissions of volatile organic compounds (VOCs) can impact the environment and affect health. We take a proactive approach to this issue and strictly require improvement. The pollution control of this project is better than the regulations. We hope to reduce air pollution and contribute to environmental protection and the health of workers.

The effectiveness of activated carbon fluidized bed control equipment.

(1)

Prevent emissions: Outperform environmental regulations and save air pollution costs.

(2)

Circular Economy: Recovery and reuse of VOC and mixed solvents.

(3)

Economies Effect: Reduce production costs and outsource to treat wastewater to resale, which could use as high-heat-fuel.

(4)

Social participate: Improve the air quality of employee and community.

Investment

Motivation：
To reduce VOCs air pollution control and reduction, we are constantly looking for ways to improve process and module test design. We are also developing and deepening environmentally friendly, green energy-saving, and recycling and reuse technologies.
----------------------------------------------
Execution condition:
Plan to set up activated carbon fluidized bed control equipment (Invest NTD 65 million dollars).

Improve the capture efficiency of VOCs from manufacture process to reduce emissions.

Integrity and improve the process equipment to reduce the energy consumption and cost.

Refine the method of VOCs capture to reach the circular economy around the wastes.

Output

External effectiveness (Society):
VOCs generated from the process is reduced by an optimized capture and treatment, which can greatly improve the negative impact on human environment and health, and largely reduced emissions. Contribute to the protection of the earth's environment.
----------------------------------------------
Opportunity effectiveness:
VOCs generated from the process could recycle back into the manufacture process or outsource to treat and then sell to relevant markets, achieving the benefits of a circular economy.
----------------------------------------------
Internal effectiveness (Company):

Improve the workplace environment.

Retrofit exhaust blower to improve the efficiency of capture to lower the power consumption by 43%. Reduce the carbon emissions 46 tones/CO₂e annually and save the air pollution fee.

Waste liquor was recycled and back into the manufacture process to reduce the production cost.
