If you're questioning what goes in the trash, recycle container or compost bin, do some research before you hastily throw it in the wrong place. Wine corks and natural sponges can't be recycled, but they can be composted. Most recycling centers cannot accept shower curtains and liners because they are made of pvc. Yogurt cups, plastic utensils and toothbrushes are also made from a plastic that's not recyclable.
