For some waste materials such as plastic, recent technical devices called [[recyclebot]]s<ref name="RPJ">{{cite journal |last1 = Baechler |first1 = Christian |last2 = DeVuono |first2 = Matthew |last3 = Pearce |first3 = Joshua M. |year = 2013 |title = Distributed Recycling of Waste Polymer into RepRap Feedstock |url = https://www.academia.edu/2643418 |journal = Rapid Prototyping Journal |volume = 19 |issue = 2 |pages = 118–125 |doi = 10.1108/13552541311302978 |s2cid = 15980607 |access-date = 29 December 2017 |archive-date = 2 December 2021 |archive-url = https://web.archive.org/web/20211202111135/https://www.academia.edu/2643418 |url-status = live }}</ref> enable a form of distributed recycling called DRAM ([[distributed recycling additive manufacturing]]). Preliminary [[life-cycle analysis]] (LCA) indicates that such distributed recycling of [[HDPE]] to make filament for [[3D printers]] in rural regions consumes less energy than using virgin resin, or using conventional recycling processes with their associated transportation.<ref name="LCA">{{Cite journal|last1=Kreiger|first1=M.|last2=Anzalone|first2=G.
