Shandong Hengfeng Rubber & Plastics Co., Ltd. was established in August 1995 with a registered capital of RMB 220 million. The company’s principal business activities include the production and sale of tires and rubber products, as well as the import and export of its own manufactured goods. Covering an area of approximately 1.6 million square meters, the company boasts total assets exceeding RMB 5.5 billion and employs more than 6,000 staff. Its production capacity is 6 million sets of semi‑steel passenger car radial tires and 2.3 million sets of all‑steel commercial vehicle radial tires per year, supported by a fully developed infrastructure and ancillary facilities.

Since its establishment, the company has remained committed to technological innovation, leveraging a national-level technology center as its R&D platform. It has introduced cutting-edge manufacturing technologies and state-of-the-art production equipment from Europe, the United States, Japan, and other regions, established a comprehensive quality assurance system, and obtained certifications including China’s Compulsory Product Certification (CCC), ISO 9001 international quality management system certification, IATF 16949 quality management system certification, U.S. Department of Transportation (DOT) safety certification, and European Economic Commission (ECE) product safety certification.

In this public notice, the Shandong Provincial Department of Ecology and Environment, in its “Notice on Issuing the List of Enterprises Required to Undergo Mandatory Cleaner Production Audits in 2024” (Document No. Lu Huan Zi [2024] No. 48), mandates the implementation of cleaner production audit activities.

II. Emissions of Pollutants

1. Flue gases generated from the internal mixer, calendering, and vulcanization processes primarily contain total non-methane hydrocarbons. After collection and purification, emissions comply with regulatory standards, with concentrations below 10 mg/m³.

2. Hazardous waste primarily consists of waste lubricating oil generated by equipment such as internal mixers, with an annual production volume of approximately 25 tonnes, which is disposed of by a licensed hazardous waste treatment facility.

III. Major Energy Consumption Overview

1. Steam is primarily used in tire manufacturing and currently accounts for an annual heat consumption of approximately 1,155,411 GJ.

2. Electrical energy, used for all power-driven equipment and other applications, currently accounts for approximately 196.5 million kWh per year.

IV. Status of Risk Prevention and Control Measures

1. Level-1 Prevention and Control Measures

(1) A circular trench shall be added at the plant boundary of each production unit, and a stormwater–wastewater switching system shall be installed.

(2) A 1-meter‑high containment dike shall be installed at the tank farm boundary, and the tank farm floor shall be renovated to a non‑sparking flooring system.

2. Secondary Prevention and Control Measures

The project includes two 200 m³ emergency containment ponds, ensuring that wastewater does not discharge externally in the event of an accident.

3. Tier-3 Prevention and Control Measures

Cut-off measures will be installed at the plant’s combined wastewater and stormwater discharge outlets to prevent process materials from entering surface water bodies via the stormwater and wastewater pipelines in the event of an accident.

4. Environmental risks primarily refer to fire and explosion incidents caused by the leakage or ignition of oil products and sulfur. Mitigation and response measures encompass both internal and external actions. Internal measures include containment, isolation, absorption, automatic alarm systems, and monitoring equipment. External measures comprise public evacuation, installation of warning signs, emergency water supply, and emergency medical services.
