The regulatory definition of a business includes airports. Therefore, airports would be required to recycle solid waste generated on the airport’s premises using one or more of the methods outlined in the regulation.
In addition, airports can require airlines to handle the waste that is removed from the aircraft in California in a prescribed manner. The airlines would be required to comply with the airport’s requirements, provided there is no conflict with federal requirements for solid waste handling (e.g., the United States Department of Agriculture requirement that food waste from international flights be incinerated or sterilized).
In cases of conflict, federal law preempts state, local or private regulation.
