Pennsylvanians have called for action on climate change and resource reuse in the commonwealth. Although the commonwealth has delayed action on a number of "zero waste" bills, Pennsylvania recently took action to join other states in supporting waste-to-energy and advanced recycling. On Nov. 25, Gov. Tom Wolf approved House Bill 1808 (now, Act No. 127), which amends Pennsylvania's Solid Waste Management Act by categorizing "advanced recycling" as manufacturing rather than waste processing or treatment.
