“…FFA accumulation in the recovered oil can be due to the high moisture content or too long waiting time for the palm fruits to be processed [18]. Besides, nearly identical results had been obtained by previous researchers; for instance, a high amount of FFA was detected from the residual oil recovered by the soxhlet method (27.67 ± 0.10% ) and novel polypropylene nanofiber (25%) [11,19]. Yet, this situation can be manipulated by processing the palm fruit or utilizing the recovered oil as value-added products.…”

“…POME is mainly produced through the separation of oil from the CPO solution. The main composition of POME is water (95-96%), followed by 4 -5% total solid, 2 -4 % suspended solid and 0.6 -0.7 % oil [11]. The palm oil industry is concerned about the oil losses through POME since it contributes to reducing OER.…”

“…As shown in Table 5, the moisture and dirt content for all three runs exceeded these values; the lowest value obtained is 1.01%. The phenomenon might be due to the large quantities of non-toxic organic in the POME, supported by the obnoxious odour of the waste [11]. Ahmad et al [22] had stated that just about 50% of water spent in the palm oil separation process was released as steam, while the remaining half resulted in POME.…”

Abstract. Oil extraction rate (OER) is essential in measuring palm oil mills' performance and competence. One of the attempts to achieving high OER is exploring the possibility of recovering residual oil from palm oil mill effluent (POME). A recent technique called progressive freezing (PF) has been proposed to reclaim the residual oil from POME, forming a block of solid oil in the system. This article focuses on evaluating the quality of the recovered oil through its physicochemical characterization (free fatty acid (FFA), deterioration of bleachability (DOBI), moisture content and dirt analysis) before deciding on the subsequent usage or suitable treatment if needed. The results show that the residual oil contained 25 to 27% free fatty acid (FFA), 1.01 to 2.02% moisture content, 0.049 to 0.055 dirt and had deterioration of bleachability (DOBI) between 2.3 to 2.7. The recovered oil had been proposed to be suitable for recycle or utilization as a value-added product such as biodiesel production.

“…Based on the current global vegetable oil demand, the production of crude palm oil (CPO) is expected to reach 25.6 million tonnes by 2050 [4]. There are almost 800 palm oil mills operating in the world and producing crude palm oil, and 50% of them are in operation in Malaysia [5]. Up to today, Malaysia has implemented the B5 (blend of 5% palm oil and 95% petroleum diesel) and B7 (blend of 7% palm oil and 93% petroleum diesel) biodiesel programs in various sectors, including fisheries, government sectors, and industry.…”

The Challenges of a Biodiesel Implementation Program in Malaysia

The palm biodiesel industry is facing many challenges implementing biodiesel program in Malaysia. This paper addresses the importance of the B10 blend (10% biodiesel, 90% petroleum diesel), global challenges of palm oil import and export, and protective measures for continuous positive growth of the palm oil sector. Palm oil is the backbone of Malaysia’s economy, covering more than 5% of its gross domestic product (GDP). The key steps taken by the Malaysian government for the successful implementation of the B10 program are discussed in this review study. Till now, B5 and B7 biodiesel programs have been successfully implemented in Malaysia. The B10 biodiesel program is attractive because of the developed local palm oil sector. The B10 biodiesel program will increase the use of renewable energy sources, and is expected to increase the productivity of palm oil and biodiesel implementation in the country. Despite successful B5 and B7 programs, Malaysia is facing challenges for the implementation of biodiesel due to fluctuation in crude palm oil prices, low domestic usage of palm oil, and vehicle warranty. The improvement of palm oil and promotion of B10 through targeted agencies in the central region of Malaysia will help to implement the biodiesel program successfully.
