| Summary: | The Malaysian palm-based oleochemicals industry is growing rapidly and producing an
increasing array of products like fatty acid methyl esters, fatty alcohols and glycerine. In
the production of these oleochemicals, by-products are produced in which many of
them are potentially useful. One of the by-products is glycerol residue which is
generated by a glycerol refining plant (the glycerine source is from methanolysis of
palm kernel oil). Glycerol residue is a waste under Schedule Waste SI8I of the
Environmental Regulations in Malaysia. Currently, this waste is disposed off in landfills
with the cost of about RM700.00/tonne. This research was therefore undertaken to
characterize the glycerol residue, and to recover and utilize its valuable components. It
was found that thirteen batches of glycerol residue, GRI to GR13, showed variation in
the contents of glycerol, ash, moisture and matter organic non-glycerol (MONG). Salt
(63.7%), glycerol (19.7%) and MONG (12.9%, mainly as soap) were the three main |
