Chemical leasing is a way of doing business that helps companies be more environmentally friendly. Instead of buying chemicals like oil, water, and other materials, companies can use chemical leasing to rent these resources. They only rent the amount of chemicals they need for the job and, when they're done with them, send them back to the supplier who can reuse or recycle them. By not buying all the materials upfront, companies can save money and help the environment at the same time.
