In the past, it made economic sense to ship the plastic to Asia, because shipping companies that transport China’s manufactured goods to the US end up with thousands of empty shipping containers to carry back. In the absence of American goods to fill them, the companies have been willing to ship out America’s recycling at rock-bottom rates.
Banning plastic gracery bags will (directly or indirectly) further reduce demand for recycled plastic.
I use plastic grocery bags as trash bags.
I probably haven’t used a “trash bag” for around six months.
