It needs to stop being optional and it needs to be something that is part of the product design process. Companies are not currently doing more than the bare minimum here because it is not their problem and mostly they do it to look good and there are a lot of companies for whom looking good is not much of a priority or for whom it is more about the looks than the reality. That needs to change. It needs to be their problem.
Sustainable production processes are not sustainable unless they consider the whole product cycle from production to discarding. And the simple truth is that everything gets discarded eventually. Forcing companies to think about the post sales life of their products changes how they build their products. Planned obsolescence is a lot less lucrative if you have to clean up the obsolete mess you helped create. If they are forced to think about efficiently recycling used products they produced, the economics change. Durability becomes a topic. Repairability as well and facilitating recycling by using materials that are easy to recover and products that are easy to disassemble.
