Jinan Haoyang Casting & Forging was awarded “Provincial Green Factory” - 280 tons of carbon dioxide emission reduction per year.
Jinan, May 13, 2025] In the latest Typical Cases of Industrial Green Transformation released by Jinan Ecological Environment Bureau, Jinan Haoyang Casting & Forging Co., Ltd. has been selected for its “Resource Recycling+Clean Energy” dual-wheel drive model. Through technological transformation and refined management, the company will achieve an 18% reduction in energy consumption of 10,000 yuan output value in 2023, interpreting the deep integration of “smart” and “green” with practical actions.
Green Manufacturing Practices
1. Cleaner production upgrades
- Photovoltaic power generation system:
10,000 square meters of solar panels are laid on the roof of the factory, with an annual power generation of 1.86 million degrees, meeting 15% of the electricity demand for production and reducing carbon dioxide emissions by about 280 tons per year.
- Heat recovery device:
Waste heat from forging is used for heating in winter, replacing gas boilers, saving 120,000 cubic meters of natural gas consumption annually.
2. Resource recycling system
- The metal recycling rate is 98.7%:
Scrap steel balls and edges are crushed and processed and returned to the furnace for recycling, reducing iron ore purchases by 12,000 tons per year.
- Cooling water recycling:
Closed-loop water treatment system reduces water consumption per ton of product to 0.5 tons (industry average 1.8 tons), awarded “Shandong Province Water Saving Benchmark Enterprise”.
3. Environmental management system
- Digital monitoring:
Installation of 24-hour online emission monitoring equipment, real-time data docking to the platform of the Municipal Environmental Protection Bureau, with no record of exceeding the standard throughout the year.
- Supply Chain Control:
Require suppliers to provide RoHS/REACH compliance certificates, and eliminate 6 non-compliant raw material suppliers in 2024.
Social benefits and industry impacts*
- Community co-construction:
Free access to environmental monitoring data to the surrounding community, and a total of 12 public science activities on “industry and ecology”.
- Industry empowerment:
Led the development of “Green Factory Evaluation Standards for Forging Industry” and shared energy-saving technologies with 13 companies in the same industry.
Future planning*
- 2025 Target:
✅ Construction of “Zero Carbon Forging Workshop”, realizing 100% green power supply.
✅ Research and development of intelligent quenching equipment with low energy consumption, expected to reduce energy consumption in heat treatment by 25%.
✅ Provide “Green Manufacturing Engineer” training program in cooperation with universities.
