This precedent is not necessarily a company but a variety of everey-day products that are biodegradable. The reason why this is a precedent is that we want to make biodegradable every-day things that are made with plastic that is biodegradable. Some of these items that are in your home that are biodegradable that you might not know are printer paper, paper towels, toilet paper, paper plates, bowls and cups, parts of textbooks and notebooks, paper folders and cardboard boxes.
