“…The techno‐economic model of the large‐scale bioethanol production plant from microalgae was simulated with integrated process design. The simulation model was plotted based on the universal economic analysis of several chronological phases such as microalgae cultivation, biomass pretreatment, extraction and fermentation, bioethanol separation, and purification, as shown in Figure .…”

The foremost purpose of this techno‐economic analysis (TEA) modeling was to predict a harmonized figure of comprehensive cost analysis for commercial bioethanol generation from microalgae species in Brunei Darussalam based on the conventional market scenario. This model was simulated to set out economic feasibility and probabilistic assumption for large‐scale implementations of a tropical microalgae species, Chlorella vulgaris, for a bioethanol plant located in the coastal area of Brunei Darussalam. Two types of cultivation systems such as closed system (photobioreactor—PBR) and open pond approaches were anticipated for a total approximate biomass of 220 t year−1 on 6 ha coastal areas. The biomass productivity was 56 t ha−1 for PBR and 28 t ha−1 for pond annually. The plant output was 58.90 m3 ha−1 for PBR and 24.9 m3 ha−1 for pond annually. The total bioethanol output of the plant was 57,087.58 gal year−1 along with the value added by‐products (crude bio‐liquid and slurry cake). The total production cost of this project was US$2.22 million for bioethanol from microalgae and total bioethanol selling price was US$2.87 million along with the by‐product sale price of US$1.6 million. A sensitivity analysis was conducted to forecast the uncertainty of this conclusive modeling. Different data sets through sensitivity analysis also presented positive impacts of economical and environmental views. This TEA model is expected to be initialized to determine an alternative energy and also minimize environmental pollution. With this current modeling, microalgal‐bioethanol utilization mandated with gasoline as well as microalgae cultivation, biofuel production integrated with existing complementary industries, are strongly recommended for future applications. © 2019 American Institute of Chemical Engineers Environ Prog, 38:e13146, 2019

“…Table 2, a total of 645 ML potential bioethanol can be produced from rice straw in Malaysia. With the domestic gasoline consumption of about 15,800 ML/year [29], about 4.1% of gasoline consumption can be replaced with bioethanol produced from rice straw.…”

Due to rapid expansion in road transportation, a more environmentally benign fuel is required in order to control the air pollution. More competent and feasible development of the transportation sector has attracted many interests from various countries including Malaysia. Ethanol fuel is cleaner and sustainable compared to gasoline fuel. Although first generation bioethanol has been utilized globally, it raised the concern about food versus fuel issues. The solution for this is by utilizing agricultural waste as feedstock for bioethanol production. Therefore, this paper investigated the rice straw bioethanol production and its effect on economy and environment when rice straw bioethanol is utilized as a gasoline substitute in Malaysia. Approximately 6% of total gasoline consumption could be saved if rice straw is utilized for bioethanol production, while reducing 92% of air pollution. Based on the life cycle cost model, it was found that the total production cost for 50 ML rice straw bioethanol production plant with a lifetime of 20 years amounts to nearly 200 million USD, which the unit production cost is 0.16 USD per liter of bioethanol, which is Lower than the gasoline price. Therefore, Malaysia should consider bioethanol as a potential alternative fuel to address the problem of depleting fossil sources and global warming.

Starch is an edible polymer derived from plant basis. It is commonly used in food industry as it offers good stabilising effect. Moreover, starch can be easily modified either physically or chemically making it a very versatile source. For instance, its capability to be easily modified and coming from low cost source making starch as one of the most important ingredient in food preparation. There are currently varieties of commercially modified starch available in Malaysian market. For example, potato, corn, wheat and tapioca starch are presently on the top list. However, there are also numbers of unexplored native starch for example from fruits processing waste. Besides, these fruit by-products are considered as underutilised source of starch. Although there are few existing reported studies on starch extracted from fruits seed and other waste products, more new sources are believed to be explored in future according to particular starchbased products industries and demands. Therefore, this review discusses current starch based-products developments and application of unconventional starch in food industry.
