It's double ended. The scrap metals and plastics from recycled electronics are worth good money. Really good money. Same goes for the contents of your blue box and tires. Have you ever seen a Canadian Tire seacan? Ever wonder what goes into them on the return trip to Asia? Highly prized "garbage".
It's why I don't use a blue bin. Waste companies hire crews to sort garbage anyway. I get nothing for my valuable waste so why should I waste my time to sort it for them?
