I think most people agree with this idea. There are two basic problems preventing it.
- There is a giant gap between what people believe they should be doing and what they'll actually do voluntarily when faced with the slightest inconvenience.
Basically you have to make people do inconvenience things. You can't ask.
For example single-use shopping bags. Everyone understands why they are a problem. Every store sells a reusable alternative. Recyclable paper bags have always been an option. But unless it's regulated, people continue using disposable single use plastic shopping bags.
- The problem isn't just what can be recycled it's what WILL be recycled.
Imagine going through construction debris trying to separate plaster, wood-lathing wire-lathing, screws, and insulation into separate piles for disposal.
Picture the average grandma disassembling a sump pump to make sure plastic rubber Teflon and metal materials all end up in separate recyclable piles.
