The properties of WCO and cooking oil as feedstock as well as the waste concrete and the hydrated cement as catalysts were investigated thoroughly. The effect of catalyst amount and the potency of WCO as feedstock were discussed. Furthermore, we have also performed the comparative study of catalytic activity between waste concrete and hydrated cement, in which the former displays a higher activity. Finally, the waste concrete actively catalyze the biodiesel production using WCO as feedstock with the yield of fatty acid methyl ester (FAME) up to 92.92% under ambient condition using 0.5 wt.% of catalyst, 24:1 of methanol/oil molar ratio, 0.56 wt.% of NaCl (wt. % of oil) at a constant voltage of 9.6 V for 2 hours reaction. Our results show that such waste, nearly no-cost materials are highly potential as catalyst for biodiesel production.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1063/1.5065028[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
