The way to reduce the waste from plastic things is
to reduce
the quantity of such things that are made.
"Recycling" plastic by burning it is even more ironic than the article
says. The process consists basically of extracting petroleum from the
ground and then burning it, but differs from the usual way of doing so
in that the petroleum (more precisely, some fraction of it) passes
through an intermediate stage as plastic. This does not reduce the
greenhouse gas output.
Imagine if every item made of plastic — even fairly durable
items — carried a deposit. If the item is recycled in less than
5 years, the consumer gets the deposit back. If it is recycled after
5 years, the consumer refund is a decreasing fraction of the original
deposit; after 10 years, the refund goes to zero.
This law would encourage making plastic items that would remain usable
for a longer period of time. It could even help put an end to planned
obsolescence.
