Eight samples of glycerol residue (GR1-1 to GR1-8) from one batch (GR1) were subject to chemical and physical treatments to recover crude glycerine, crude fatty acids and salt. The average weight percentages of the recovered components were: crude glycerine 33.9%, crude fatty acids 10.5% and salt 65.2%. The average composition of the recovered crude glycerine was: glycerol 51.4%, ash 13.8%, water 8.9% and matter organic non-glycerol (MONG) 25.9%. Crude glycerines with pH from 1-2 and 5-7 were produced. Chemical treatment at low pH (1-2) was better as it increased the glycerol and reduced the ash contents in the recovered crude glycerine. However, the MONG content was slightly increased. The treatment also increased the recovered salt and reduced the crude glycerine (giving a crude glycerine with lower dissolved salt and higher glycerol), but did not affect the recovery of crude fatty acids
