In 2015 we decided to make a conscious effort to provide more sustainable products inside and out, formula and bottle.  Our clear plastic bottles are made incorporating sugar cane resin which reduces the amount of new petroleum based plastic being used.  And sugar cane is a renewable source that captures 2.15 lbs of CO2 for every pound of sugar cane resin produced versus petroleum-based resin which emits 1.83 lbs of CO2 for every pound of resin produced. Plus our bottles are recyclable!
