Business is picking up for Expera Specialty Solutions in Kaukauna.  With chains like Starbucks and McDonalds moving away from plastic straws, specialty paper mills are answering the challenge.  A spokesperson for Expera says people actually used paper straws before they used plastic ones.  Communities which ban plastic bags and bottles are also beneficial.  Expera has four paper production facilities in Kaukauna, Nicolet, Rhinelander, and Mosinee.
