Poppycock.
At home you recycle so you don't get a fine.
At work you recycle so your company doesn't get a fine.
Given that you get a fine whenever you fail to recycle, there is a financial incentive to recycle. But it is not a positive incentive.
Some recycling supports itself. Nobody throws away automobiles because they have scrap value. If your company produces a lot of waste that is fairly easy to segregate and collect, then some recycling of certain materials can be a paying proposition.
But I defy you to show me a single instance where the mandated levels of recycling, sorting out all recyclable plastic, tin, aluminum, misc. metals, glass, high-grade paper, and newsprint, makes economic sense absent the threat of fines.
I'm sure some people do it, and they have their reasons. But economics is not one of them.
