“…Ethanol is arguably the most successful alcohol fuel that has been mass produced and used in large scale [16][17][18][19]. Brazil has developed ethanol from sugarcane since 1975 with the PRO-ALCOOL programme and has reduced its dependency on fossil fuel imports [20][21][22][23][24][25]. However, ethanol has several problems to solve.…”

The properties of butanol offer more promising results compared to those of lower chain alcohol such as methanol or ethanol. However, butanol as a biofuel has not yet been commercially produced due to its costly process. Butanol is generally produced via the process of Acetone-Butanol-Ethanol (ABE) fermentation and can only be acquired after it was recovered from the ABE solvent. Despite the efforts and recent developments, obtaining higher butanol concentration from ABE fermentation is still relatively expensive and challenging. The idea of using ABE directly in internal combustion engines is then proposed to eliminate the recovery process. Several preliminary studies have reported several promising results of using ABE blends in both gasoline and diesel engines. However, researches in this area are still in the early stages, and thorough investigations are required. This review paper aims to provide essential findings from the latest development in the addition of ABE both with gasoline and diesel fuel in Spark Ignition (SI) and Compression Ignition (CI) engines. A brief discussion on ABE properties will be firstly given before the effects of its addition on SI and CI engine is comprehensively reviewed. The end of this article highlights some possible contributions and research gaps.

“…Governments around the world have supported biofuels as strategic technologies to reduce carbon emissions in transport while contributing to economic development in rural areas and reducing dependence on imported fossil fuels. Conventional biofuel technologies, also known as 'first-generation' biofuels, have relied on the use of sugar, starch, and oil-based feedstock to produce ethanol and biodiesel worldwide, particularly in Brazil and the United States [17]. However, conventional biofuels have shown limited capacity to advance these objectives and to significantly reduce climate changing emissions.…”

In this article, we explore the opportunities and challenges of landscape approaches through the lens of responsible research and innovation (RRI). We use the case of transport biofuels to reflect on the capacity of landscape approaches to support the governance of emerging technologies. The case study, developed in the region of Sardinia, Italy, consists of a landscape design process for the implementation of biofuel technologies that rely on the use of non-food dedicated crops and agricultural residues. By using non-food feedstocks, the biofuel project aims to avoid competition with food production and achieve sustainability goals. Through the discussion of key dimensions of RRI in relation to this case, the article puts forward a set of critical aspects of landscape design processes that require further attention from theorists and practitioners in the field of landscape-based planning. These include the power imbalance that exists between the diverse actors involved in project activities, a need for improving the flexibility of the configuration of socio-technical systems, revising assumptions on ‘valid’ knowledge, and improving the deliberative component of planning processes.

“…Research in biofuels aims to achieve two essential goals. The first goal is to improve energy security as current fossilfuel reserves are decreasing rapidly, while at the same time global energy consumption is increasing enormously [1][2][3][4][5]. The second goal is to reduce emissions to meet more rigorous emission protocols imposed by governments and authorities all over the world [6][7][8].…”

“…Several studies have demonstrated that the ethanol-biodiesel blends can solve the trade-off between Particulate Matter (PM) and Nitrogen Oxides (NOx) in CI engines [41,42]. As a result, ethanol is extensively used throughout the world [2,43,44]. Brazil can produce affordable ethanol fuel from the fermentation of sugarcane to supply its transportation sector [45][46][47][48][49][50], whereas the US produces ethanol from corn grain to supply its domestic demands [51][52][53].…”

Several studies on ethanol as a biofuel have been comprehensively carried out. Today, a growing interest in longer chain alcohols has emerged due to their favourable physical and thermodynamic properties. Butanol or butyl alcohol with 4-carbon structure (C4H9OH) is a more promising biofuel as it outweighs methanol and ethanol in several ways. The production cost of butanol has been gradually reduced, and rapid progress in the development of its production technology has allowed butanol to be produced more effectively. However, studies on the effect of butanol on gasoline or spark ignition (SI) engines are not as comprehensive as the abundant research of ethanol. This paper highlights recent novelty and contribution of butanol addition in SI engine. Results of new approaches on the engine’s performance, combustion and emission characteristics are summarised. Reviews from this paper suggest that there are some gaps in the addition of butanol found in the literature. Thus, several encounters and forthcoming research directions are outlined in the final section of this review article, highlighting several possible contributions that have not yet been carried out using butanol as a biofuel in a gasoline engine.
