An increasing number of products are made using recycled materials, such as newspapers and soft drink containers. 
Yea. thats great. Hopefully its being done in a way where they can be continually recycled like Aluminum which has a high reclamation value
Salvage value is how much something is worth after it's intended use, and it varies based on who is determing it.
How does salvage value affect recycling? I don't think there's much value in plastic or aluminum outside of re-using it commercially. Scrap metal and wood seems to have more salvage value
It all depends, the automobile is the single most recycled product in the US. 
does selling a used auto count as recycled? or does it have to be dismantled?
Interesting question, I would say yes it is a form of recycling, getting reuse from an old item.
yea. that make sense. I get really frustrated by people who don't do easy recycling. Our city collects recycling but i see people toss cardboard and other basics in the trash
It's hard because places have different rules and regulations and people give up when something isn't easy.
