Resource recovery and cdm profit from palm oil mill effluent

Tan K. K., . (2008) Resource recovery and cdm profit from palm oil mill effluent. [Proceedings Paper]

A novel holistic resource recovery system for palm oil mill effluent POME has been developed and tested successfully. The system will recover oil and remove the sludge that may be used to fertilize estate land after composting. The process offers very high carbon credit by methane gas avoidance through the clean development mechanism COM and will also reliably produce a final effluent with BOD3 below 20 mg/L of Standard A. Thus far there has been no successful treatment system of palm oil mill effluent POME being installed because POME is a complex oily colloidal suspension with approximately 0.5 oil and 3 solids which defy conventional wastewater treatment. Treatability tests conducted in a laboratory and a mill shows that a combination of flocculation with special admixture an innovative cooling process and separation process could remove 90 of solids and BOD. Computation based on the new influent for the ponding system will yield a final effluent BOD of less than 2 mg/I which is below Standard A. It is anticipated that POME of existing mills can be treated effectively with minimal costs and some process modifications a trade secret which may be financed by the substantial carbon credit earned from methane gas avoidance. For a 90TIh mill the expected annual CER potential C02eq MT/yr derived from this technology should be at least 50 000 MT/yr and would be approximately ‚550 000 at a nominal ‚ 10 per MT.

Abstract

A novel holistic resource recovery system for palm oil mill effluent POME has been developed and tested successfully. The system will recover oil and remove the sludge that may be used to fertilize estate land after composting. The process offers very high carbon credit by methane gas avoidance through the clean development mechanism COM and will also reliably produce a final effluent with BOD3 below 20 mg/L of Standard A. Thus far there has been no successful treatment system of palm oil mill effluent POME being installed because POME is a complex oily colloidal suspension with approximately 0.5 oil and 3 solids which defy conventional wastewater treatment. Treatability tests conducted in a laboratory and a mill shows that a combination of flocculation with special admixture an innovative cooling process and separation process could remove 90 of solids and BOD. Computation based on the new influent for the ponding system will yield a final effluent BOD of less than 2 mg/I which is below Standard A. It is anticipated that POME of existing mills can be treated effectively with minimal costs and some process modifications a trade secret which may be financed by the substantial carbon credit earned from methane gas avoidance. For a 90TIh mill the expected annual CER potential C02eq MT/yr derived from this technology should be at least 50 000 MT/yr and would be approximately ‚550 000 at a nominal ‚ 10 per MT. The recovery of solids may provide the option ofvaluable co-composting with EFB or the production ofbiofuel in the form of dried sludge cake.
