What wonderful proof of how clueless the people calling for the ban are. You have no idea what the consequences would be but there is one relevant fact: it takes 4 times the energy to produce a paper cup over a styrofoam cup. On top of that the chemical waste from processing paper suitable for use with food far exceeds the waste from styrofoam cup production. Based on this data point is perfectly reasonable to point out that suppliers of wooden utensils will consume more energy and if that energy comes from coal it will produce more GHGs. Put producing more GHGs in China is fine as long as people here can pretend to be virtuous because they are using wooden utensils.
It takes a bit more energy to produce a paper cup over a Styrofoam one, certainly not 4 times. And then there's the environmental problem with the latter.
Some reading for you.
Compared to making paper cups, manufacturing polystyrene cups:
requires about 42 percent less water
needs about 17 percent less energy
uses 22 percent less petroleum to source materials and ship cups
doesn’t call for chemicals that can harm water if not disposed of properly, such as chlorine dioxide
doesn’t necessitate the cutting of trees
In contrast, when compared to foam cups, paper cups:
produce about 28 percent fewer greenhouse gasses
decompose in a landfill in 20 years, as opposed to 1 million-plus
decompose in water in just a few days, instead of 50 years
are far easier to recycle and recycled at a higher rate
aren’t toxic (see above)
