The environment has become a central political concern for citizens across the world for centuries. However, over the last 50 years, environmentalist movements have helped shift public opinion, businesses, and governments to institute policies that promote sustainability and reduce carbon footprints. One of those policies is recycling. Recycling is a service that many municipalities provide as a public service or contract with a private firm. Recycling is also provided by companies who will accept products that can be recycled in exchange for money or some sort of line of credit.
