Is there any rea­son why plas­tic bot­tles can­not be reused in the way glass ones were in the past?

BBC Earth (Asia) - - Q & A -

Ex­ist­ing plas­tic bot­tles are de­signed for sin­gle use and aren’t sturdy enough to with­stand the wear and tear as­so­ci­ated with col­lec­tion, clean­ing, re­fill­ing and re­use on a com­mer­cial scale. Reusable bot­tles need to be ster­ilised, which in­volves wash­ing with very hot wa­ter and pos­si­bly chem­i­cal so­lu­tions to kill any bac­te­ria. But while glass is re­sis­tant to high tem­per­a­tures and to many cor­ro­sive chem­i­cals, most plas­tics are li­able to melt, de­form or sus­tain dam­age from these clean­ing meth­ods. Nonethe­less, it might be pos­si­ble to pro­duce a reusable plas­tic bot­tle, but to the best of our knowl­edge no com­pany has done this yet. AFC
