Ive been thinking about how many industries end up with surplus materials, parts or even packaging that often go unused or get thrown away. In other areas, like running an online thrift store for clothing, there is already a clear system for giving items a second life instead of sending them to landfill.

Im curious what this could look like in more technical or industrial settings. Are there practical examples of companies reusing or repurposing surplus materials from tanks, equipment or production lines in a way that is both safe and economically sensible?
