The Metropolitan Environmental Trust (The M.e.t.) is a non-profit governmental trust that promotes environmental responsibility by providing environmental education to the public and hosting awareness and special collection events. It also collaborates with member communities to develop, deliver, and support environmental programs and services that follow regulatory compliance, teach sound environmental practices, and reduce the solid waste stream.

The M.e.t. got its start in 1987 as a committee charged with looking into alternatives to land filling Tulsa’s trash. After completing studies, the Trust decided it was necessary to begin recycling operations. In 1993, The M.e.t. opened its first recycling center. Now the M.e.t. has 10 recycling centers in 8 of its member communities.
