Solid waste management is one of the challenging problems worldwide and it is becoming more complex by the increase in population and subsequently the waste generated. In Malaysia, among industrial solid waste palm oil mill waste (POMW) contributes the highest share. Wastes from the oil palm mill includes palm oil mill effluent (POME), decanter cake, empty fruit bunches, seed shells and the fibre from mesocarp. Generally most of the waste generated is either disposed of via open dumping or used as fertilizers as such or as animal feed. Land application of POMW and POME is very common practice as it contains numbers of plant nutrients. Direct application of POMW into agricultural soil can result in a number of problems such as water pollution, leaching etc. To deal with these problems, vermicomposting of palm oil mill waste may be a sustainable waste management option. There are number of researches going on management of biomass residues from palm oil mill, but very few works are going on vermicomposting of these agro-industrial waste. Vermicomposting of POMW can be a good practice as it will also be helpful in recycling the useful plant nutrients and it is better than that of composting process. Present review deals with the various aspects of vermicomposting of POMW and its importance. Review also put forward the effect of potential application of vermicompost on plant growth. On the whole it looks for the possibility of vermicomposting of waste from palm oil mill as a sustainable waste management alternative.
