It depends on what equipment local recyclers have available. The bottle caps and the bottle are made of different materials which presents a problem when it comes to recycling. The cap is a hard plastic, either high density polyethylene (HDPE), or polypropylene, while the bottle is made of polyethylene terephthalate (PET). These plastics have very different melting points, 260<sup>o</sup>C for PET and 140-150<sup>o</sup>C for HDPE and polypropylene.</p> Fri, 14 Oct 2022 16:25:12 +0000 Joe Schwarcz Phd 9266 at /oss
