Coca-Cola’s PlantBottle™ packaging in Great Britain currently consists of up to 22.5% plant-based PET plastic, 25% recycled PET plastic, and 52.5% conventional PET plastic. PET plastic is composed of two parts: MEG (mono-ethylene glycol), which makes up 30% and can already be sourced from plants, and PTA (purified terephthalic acid), which comprises 70% and is not yet commercially viable from plant-based sources. While laboratory tests have demonstrated the feasibility of plant-based PTA, Coca-Cola continues to work with research partners to develop an environmentally sustainable method for large-scale production. Future plans include using materials like wood chips, fruit peel, and wheat stalks. The company aims to make all plastic bottles from a mix of plant-based materials and recycled plastic by 2020.
