When you do recycle, you should know what belongs in the bin: Rinsed plastic containers and glass bottles, cardboard, and beverage and food cans are almost always acceptable. Plastic bags, electronics, and paper covered with food generally are not. Neither are insulated coffee cups and toothpaste tubes, in most cases. And if you’ve checked your local guidelines to see if an item is recyclable and you still aren’t sure, it’s best to ignore your wishful instincts and throw it in the trash.
