The ecological impact of modern society has become a major issue in today’s world. Buzzwords like green jobs, renewable energy, greenhouse gases, and more are taught in schools, discussed in business, and used political speeches. Many of these concepts are built on the idea of sustaining modern society with renewable energy sources, foods, and products. In manufacturing, process efficiency is the best way to reduce the impact on the environment and sustain production. Die casting sustainably produces cast products with recyclable materials, while conserving energy, and creating a small carbon footprint. In addition, the die casting supply base in the US is continually improving its efficiency making it an increasingly sustainable process.
