(a) The Georgia Building Authority is authorized to establish and coordinate a state-wide recycling program for state agencies and to establish, engage in, contract for, or otherwise allow or arrange for a collection program for recovered materials generated as a result of agency operations including, but not limited to, aluminum, high-grade office paper, and corrugated paper and for the mulching or composting of yard trimmings. The Georgia Building Authority is authorized to establish procedures for the collection and storage of such materials from any property or building utilized by the state or any agency thereof and to enter into contractual or other arrangements for the transportation, disposition, or sale of such materials. Proceeds generated from such sale shall be used by the Georgia Building Authority for the purpose of offsetting the costs and expenses of administering and implementing the recycling program.

(b) Nothing in this part shall prohibit any state agency from engaging in, contracting for, or otherwise allowing or arranging for its own recycling program for recovered materials generated as a result of its own agency operations.
