Double Coin Tire's Energy Efficiency Project Yields Remarkable Results

Recent reports indicate that the PM2.5 concentration in the Chongqing Shuangqiao Economic and Technological Development Zone has consistently met the national secondary standard for five consecutive years. Among the contributors to this achievement is Double Coin Group (Chongqing) Tire Co., Ltd., whose clean energy transformation project has played a significant role in reducing regional emissions and improving air quality.

Clean Energy Transformation: A Milestone for Sustainability

In January 2023, Double Coin Tire completed and commissioned its groundbreaking clean energy transformation project, transitioning from coal to natural gas (commonly referred to as "coal-to-gas"). The project represented a total investment of 16.52 million yuan, of which 6 million yuan came from the Central Government's Special Fund for Air Pollution Control.

The project included the installation of a new 35t/h natural gas boiler and the decommissioning of two 75t/h coal-fired power plant boiler units. To ensure environmentally sound operations, the facility was equipped with a Regenerative Thermal Oxidizer (RTO) system for treating volatile organic compound (VOC) emissions and a steam ejector device to recycle waste steam from the vulcanization process. These measures marked a significant step toward adopting cleaner and more efficient technologies in the tire manufacturing sector.

Advanced Monitoring for Sustainable Operations

A cutting-edge control center was established as part of the project, enabling real-time monitoring of boiler operations and pollutant emissions. This digital system ensures strict adherence to environmental standards and allows for the rapid identification and resolution of any anomalies.

Impressive Environmental Impact

Since the project's completion, the emissions from Double Coin Tire’s natural gas boiler have consistently met stringent environmental standards. Compared to the pre-upgrade operations, the company has achieved substantial reductions in key pollutants:

· Sulfur dioxide (SO₂): Decreased by 108 tons annually.

· Nitrogen oxides (NOₓ): Reduced by 31 tons per year.

· Particulate matter (dust): Lowered by 11 tons annually.

In addition to cutting air pollutants, the project has also resulted in a dramatic reduction in the company’s overall carbon footprint. Each year, the transformation eliminates the equivalent of 12,000 tons of standard coal consumption and prevents the release of 31,000 tons of carbon dioxide (CO₂). This aligns with global trends toward decarbonization and supports China’s broader carbon neutrality goals.

Regional Leadership in Green Manufacturing

Double Coin Tire’s energy efficiency project exemplifies how the manufacturing industry can balance production efficiency with environmental responsibility. By proactively embracing clean energy and advanced emissions control technologies, the company has set a benchmark for sustainability in the tire industry and the Chongqing region.

This initiative not only enhances the company’s competitiveness but also significantly contributes to the broader community’s efforts to improve air quality and reduce greenhouse gas emissions. As more companies follow Double Coin’s lead, the transition to greener industrial practices will undoubtedly accelerate, paving the way for a more sustainable future.
