Palm Oil Mill

Malaysia is one of the world’s largest palm oil exporters, amounting to 39 % of world palm oil production and 44 % of world exports [1]. Palm oil mill usually engaged with odour problem that came from the wastewater treatment pond that released odourous compounds such as ammonia, volatile organic acids, and sulfides. This study was done to investigate odour nuisance from palm oil mill operations and odour emission rate at United Oil Palm (UOP) Mill, Nibong Tebal, Penang, Malaysia. Odour assessment was done on-site at four points and odour sample was taken from four anaerobic treatment ponds. Flux hood method was used and the samples were analysed by using the olfactometry method with six panels. It was found that in the UOP mill, the highest odour emission is from the anaerobic pond 2 with the average specific odour emission rate of 10.88 OUE/sm2, follow by cooling pond, acid pond and anaerobic pond 1. Besides knowing the main source of the odour, this study was run to find the intensity and offensiveness of the palm oil mill odour. A simple questionnaire was asked to the six panels about the odour intensity and odour offensiveness, and the average for both was at 5 (very strong odour) and 3 (definitely offensive odour). Higher level of offensiveness and intensity will increase the odour complaints, but by knowing those levels, it will help in deciding the limit of odour concentration that can be released and the threshold of odour that can be accepted by humans.

Abstract Gas recovery systems at palm oil mills enable the curtailment of uncontrolled greenhouse gas emissions from open anaerobic pond, but can also reduce odour, an aspect which has not yet been substantiated. The objective of this study is to evaluate the odour emission from palm oil mill effluent and the effectiveness of covers and tank digester in reducing odour emission from the open lagoons. Odour samples were obtained from the cooling ponds in conjunction with in-field odour assessment performed on site. Results demonstrated that odour released from open ponding or covered lagoon were almost comparable, ranging from 33,150 – 162,000 OU/m3, and 68,705 – 102,000 OU/m3, respectively. In contrast, odour emission from cooling pond which used tank digester system seemed markedly lower, ranging between 13,000 – 76,000 OU/m3. In fact, the analysis of ambient air close to anaerobic tank digesters proved a reduction of odour emission to the surroundings (with 3.5 OU/m3, weak intensity) compared to open pond (with 2700 OU/m3, strong intensity) or covered lagoon (with 111 OU/m3, distinct intensity). In conclusion, gas recovery systems at palm oil mills should be promoted not only towards the management of greenhouse gaseous, but also as an odour impact management strategy.

Processing of palm oil generates enormous quantities of wastewater commonly called palm oil mill effluent (POME). The aim of the research was to evaluate the effect of POME as organic fertilizer on Melaleuca cajuputi seedling. The research was conducted at PT. Bukit Asam from November 2016 until March 2017. POME used was from PT. Bumi Sawindo Permai at Tanjung Enim, South Sumatera. POME from Fat pit, cooling pond, anaerob pond and maturity pond were applied to seedlings at nursery with different concentrations of POME Fat pit (625, 417, and 208 mL), Cooling pond (695, 463, dan 232 mL), Anaerob pond (738, 492, dan 246 mL), and Maturity pond (968, 645, dan 323 mL). The result showed that POME from Anaerob pond 246 mL increased the growth of M. cajuputi with plant high 47.35 cm and stem diameter 5.57 mm and total dry weight of CM (Calopogonium mucunoides) was 26.83 g.Key words: ex-coal mine soil, Melaleuca cajuputi, POME
