The EPA estimates 5.7% of LDPE (recycling number 4) is recycled.<br /> <br /> Despite competition from more modern polymers, LDPE continues to be an important plastic grade.<br /> <br /> In 2013 the worldwide LDPE market reached a volume of about US$33 billion.<br /> <br /> == See also ==<br /> <br /> * [[High-density polyethylene]]<br /> * [[Injection molding]]<br /> * [[Computer numerical control (CNC)]]<br /> <br /> == External links ==<br /> <br /> * [https://en.wikipedia.org/wiki/Hobby_injection_molding Hobby injection molding] @ Wikipedia<br /> <br /> [[Category:Injection molding]]<br /> [[Category:Materials]]</div>
