Hello people ! in this video we transform the fatty acids made before into ethyl ester. The whole procedure is a two-step synthesis of biodiesel from waste soap bars. #chemistry #zodachem #esterification #fischer #biodiesel Link to our waste to resource playlist: th-cam.com/video/gEFRcA_D3bQ/w-d-xo.html

Hello people, in this video we explore some luminescence from food: the phosphorescence of peanut butter. Please enjoy ! #zodachem #physics #phosphorescence #luminescence #fluorescence

Hello people ! The preparation of calcium acetate from clamshells is presented. The procedure is analog to eggshells. It is another example of getting resource from food waste. Procedure can be extended to snails and oyster shells. Link to video: th-cam.com/video/hkcJJt7_24s/w-d-xo.html #scienceexperiment #zodachem #chemistry #clamshell #zerowaste #capcut

Hello people, in this video we prepare biodiesel from waste cooking oil. Transesterification is performed easily with common denaturated ethanol found in grocery store and sulfuric acid as catalyst.
