I don't really believe in waste as a concept, waste is just an underutilized resource. Back in the day gasoline was a waste product of the refining process. So called "food waste" can be composted and used to grow new food. Water is infinitely recyclable. So are most if not all of the materials in electronic devices. The landfills of today will be gold mines in the future.
They somewhat already are in some areas. We have a mission place that takes old computers and rehabs them for the poor and our city has a place you can drop off electronics, they have some deal with people who come pick them up, they either fix and sell them or tear them down for parts which decreases the amount being thrown away. They also implemented a burn to energy center using the best technology to capture burn off waste. This will come in handy now that China has stopped accepting recyclable's from the US because of to much contamination, that created a huge dump on prices and demand.
there are some facilities that crush up and extract all the valuable metals and such from electronics. There are some recycled materials that are not all that useful or worthwhile to recycle.
Some things are made and can't be reused or recycled, like styrofoam and other oil-based products.
Styrofoam and other plastics can be recycled.
