Largest bottle-to-bottle recycling plant (by capacity)

A bottle-to-bottle recycling plant is a facility dedicated to collecting old PET (polyethylene terephthalate) plastic bottles, transforming them into rPET (recycled PET) pellets or flakes, then using this raw material to produce new bottles. In terms of processing capacity, the largest bottle-to-bottle plant currently in operation opened in October 2020 in Reading, Pennsylvania, USA. Owned by CarbonLITE, the facility covers an area of 270,000 square feet (25,000 square metres) and, once at full capacity, is projected to be able to annually process 70,000 US tons (63,500 tonnes) of PET plastic, equating to around 2.5 billion bottles.

CarbonLITE also inaugurated another bottle-to-bottle facility in Riverside, California, USA, in March 2020, which is estimated to recover around 2 billion PET bottles annually from the state's Curbside and Redemption Value programmes. That plant has a slightly smaller footprint of 220,000 sq ft (20,450 m2).
