How do foundries manage the environmental impact of melting cast iron for figurative sculptures?

Foundries employ several strategies to manage the environmental impact of melting cast iron for figurative sculptures. First, they use advanced filtration systems to capture particulate matter and reduce air pollution. Many modern foundries also transition to electric induction furnaces, which are more energy-efficient and emit fewer greenhouse gases than traditional coke-fired cupolas. Recycling scrap iron is another key practice, minimizing waste and reducing the need for raw material extraction. Some facilities implement carbon capture technologies or switch to cleaner fuels like natural gas. Additionally, water-based mold treatments and closed-loop cooling systems help conserve water resources. By adopting these sustainable methods, foundries balance artistic production with ecological responsibility.
