“…However, the domestic production of bioethanol from lignocellulosic residues (e.g., rice straw, sorghum stalk) or agricultural by-products (e.g., molasses, bagasse) in Taiwan still posed a higher cost as compared to the imported bioethanol. It was reported that the production cost of cellulosic ethanol will be as high as NT$35-38 (US$1.2-1.3) per liter [11]. This bottleneck was inherently caused by several economic factors, including interest rate, imported crude oil price, imported bioethanol price, labor cost, land cost (or land rent), harvesting and transporting cost for lignocellulosic materials, and capital cost for purchasing production machines and equipment.…”

“…Although the technologies for the fermentation of bioethanol from various lignocellulosic sources [8][9][10][11], as well as its lifecycle analysis, have been studied by many Taiwanese scholars and researchers [12][13][14][15][16], few works have been devoted to a systematic description of the status of bioethanol use and its regulatory promotion, and the bottlenecks to domestic development from the perspectives of producers, sellers, and consumers in Taiwan [7]. Therefore, the main topics of this paper will cover the following subjects:…”

Strategies and actions for mitigating the emissions of greenhouse gas (GHG) and air pollutants in the transportation sector are becoming more important and urgent due to concerns related to public health and climate change. As a result, the Taiwanese government has promulgated a number of regulatory measures and promotion plans (or programs) on bioethanol use, novel fermentation research projects and domestic production since the mid-2000s. The main aim of this paper was to present a trend analysis of the motor gasoline supply/consumption and bioethanol supply, and the regulatory system relevant to bioethanol production and gasohol use since 2007 based on the official database and the statistics. The motor gasoline supply has shown a decreasing trend in the last five years (2016–2020), especially in 2020, corresponding to the impact of the COVID-19 outbreak in 2020. Although the government provided a subsidy of NT$ 1.0–2.0 dollars per liter for refueling E3 gasohol based on the price of 95-unleaded gasoline, the bioethanol supply has shown decreasing demand since 2012. In addition, the plans for domestic bioethanol production from lignocellulosic residues or energy crops were ceased in 2011 due to non-profitability. To examine the obstacles to bioethanol promotion in Taiwan, the bottlenecks to bioethanol production and gasohol use were addressed from the perspectives of the producer (domestic enterprise), the seller (gas station) and the consumer (end user).

“…A bioethanol production optimization model is developed and implemented to assess the feasibility of producing Taiwan's target volume of cellulosic ethanol by Wen et al, (2015). This study estimates that a usage rate of 90% on two million metric tons of agricultural waste would produce a potential maximum 410 million liters of bioethanol, enough to meet 40% of Taiwan's demand for transportation fuel.…”

This review includes works published in the general scientific literature during 2015 on the production of bioenergy and biofuel from waste residues generated during bioethanol and biodiesel production with a brief overview of current and emerging feedstocks. A section of this review summarizes literature on culturing algae for biofuels including bioreactors and open pond cultivation systems with the utilization of inorganic and organic sources of nutrients. New methods applicable to the mass culture of algae are highlighted. Algal cell harvesting and oil extraction techniques tested and developed for algae discussed alongwith policies and economics are also provided.

“…The possibility of producing cellulosic ethanol was investigated by Wen et al (2015). According to the results, they concluded that a usage rate of 90% on two million metric tons of agricultural waste would produce a supreme 410 million liters of bioethanol, which was sufficient to satisfy 40% of Taiwan's reqirement for transportation fuel.…”

In recent years, the quantity of agricultural waste has been rising rapidly all over the world. As a result, the environmental problems and negative impacts of agricultural waste are drawn more and more attention. Therefore, there is a need to adopt proper approaches to reduce and reuse agricultural waste. This review presented about 200 literatures published in 2015 relating to the topic of agricultural waste. The review examined research on agricultural waste in 2015 from the following four aspects: the characterization, reuse, treatment, and management. Researchers highlighted the importance to reuse agricultural waste and investigated the potential to utilize it as biofertilizers, cultivation material, soil amendments, adsorbent, material, energy recycling, enzyme and catalyst etc. The treatment of agricultural waste included carbonization, biodegradation, composting hydrolysis and pyrolysis. Moreover, this review analyzed the differences of the research progress in 2015 from 2014. It may help to reveal the new findings and new trends in this field in 2015 comparing to 2014.
