| 5 | Utilization of residual fatty acids in matter organic non-glycerol from a soy biodiesel plant in filaments used for 3D printing显示文摘Matter organic non-glycerol(MONG)is a considerable waste output(20%−25%of crude glyc-erol)typically landfilled by soy biodiesel plants.In this work,soy MONG was characterized for potential use as a copolymer to produce filaments for 3D printing with an intent to add value and redirect it from landfills.As a copolymer,MONG was evaluated to reduce the synthetic polymer content of the natural fiber composites(NFC).Even though the general thermal behavior of the MONG was compared to that of a thermoplastic polymer in composite applications,it is depen-dent on the composition of the MONG,which is a variable depending on plant discharge waste.In order to improve the thermal stability of MONG,we evaluated two pretreatments(acid and acid+peroxide).The acid+peroxide pretreatment resulted in a stabilized paste with decreased soap content,increased crystallinity,low molecular weight small chain fatty acids,and a sta-ble blend as a copolymer with a thermoplastic polymer.This treatment increased formic acid(17.53%)in MONG,along with hydrogen peroxide,led to epoxidation exhibited by the increased concentration of oxirane(5.6%)evaluating treated MONG as a copolymer in polymer processing and 3D printing. | Sreesha Malayil Athira Nair Surendran Kunal Kate Jagannadh Satyavolu | 2023 | Journal of Bioresources and Bioproducts2023，8，3： | 0 |
