“…There is a general assumption that biodiesel or bioenergy already fall in line with sustainability principles [22] as they are sourced from the agriculture sector. In reality, biodiesels produced using agriculture product raw materials face various environmental issues, particularly those associated with the expansion of estate crops into conservation and forestry estates [23][24][25][26]. This indirectly shows that energy policies encouraging biodiesel do not necessarily meet sustainability principles [27].…”

Palm oil-based biodiesel in Indonesia is facing critical issue with regard to its sustainability status in both upstream and downstream sides. International market of palm oil keeps questioning this sustainability standard of Indonesia oil palm. Three interrelated dimensions of sustainability should be fulfilled only if a product to gain growing market acceptance internationally, i.e. economically profitable, ecologically sound and socially acceptable. To determine the sustainability of Indonesia's palm oil-based biodiesel, this paper pays attention in particular to measuring sustainability status of biodiesel in the upstream to downstream side along its supply chain. The analysis of the sustainability of palm oil-based biodiesel in Indonesia is done thoroughly all related activities on the upstream (agricultural-cultivation activities) up to the downstream (manufacturing activities) side. A rap-bioenergy approach, which included the use of MDS (multidimensional scaling) analyses is applied in the analysis. The results of these analyses show that palm oil-based biodiesel in Indonesia is facing serious sustainability status. Among other three parameters, ecological aspect/parameter is a very serious one. This is especially the case for cultivation activities. This paper concludes that if Indonesia desires international markets to accept the existence of palm oil-based biodiesel, then improvements in ecological aspect should be priority.

“…Compared to conventional gasoline, bioethanol is highly attractive as it offers cleaner combustion that is friendlier towards the environment. Economically, the bioethanol production and supply chain are also desirable as it creates many jobs and financial opportunities for both urban and rural areas (Ştefănescu-Mihăilă 2016).…”

“…When substrates such as lignocellulosic biomass are used to produce bioethanol, this type of bioethanol is termed as second-generation bioethanol (Zhang et al 2016). It is projected that in the future, second-generation bioethanol will replace firstgeneration bioethanol, which is mostly produced from food-based materials, because of its low cost and feedstock abundance (Vincent et al 2015;Ştefănescu-Mihăilă 2016). In bioethanol production, the typical bioprocess engaged is Simultaneous Saccharification and Fermentation (SSF) as this procedure offers higher reaction rates, higher yields, and greater ethanol concentrations compared to its closest counterparts such as Separate Hydrolysis and Fermentation.…”

Abstract. Vincent M, Johnny Q, Adeni DSA, Suhaili N. 2020. Potential of Candida glabrata from ragi as a bioethanol producer using selected carbohydrate substrates. Nusantara Bioscience 12: 1-10. The flexibility and efficiency of fermenting microorganisms to convert substrates to ethanol are important factors in achieving high bioethanol yields during ethanolic fermentation. In this study, Candida glabrata, a common yeast found in fermented food, was evaluated in terms of its capability to produce ethanol using different types of carbohydrates, which included simple saccharides (glucose, maltose, sucrose), polysaccharides (starch and cellulose) and complex carbohydrates (total sago effluent, TSE). Our results indicated that C. glabrata was able to efficiently produce ethanol from glucose at 79.84% TEY (Theoretical Ethanol Yield). The ethanol production from sucrose was low, which was only 6.44% TEY, while no ethanol was produced from maltose. Meanwhile, for complex carbohydrate substrates such as starch and cellulose, ethanol was produced only when supplementary enzymes were introduced. Simultaneous Saccharification and Fermentation (SSF) of starch dosed with amylases resulted in an ethanol yield of 55.08% TEY, whilst SSF of cellulose dosed with cellulases yielded a TEY of 31.41%. When SSF was performed on TSE dosed with amylases and cellulases, the highest ethanol production was recorded within 24 h, with a yield of 23.36% TEY. Lactic acid and acetic acid were found to be at minimal levels throughout the fermentation period, indicating an efficient ethanol conversion. A notable increase in C. glabrata biomass was observed in cultures fed with glucose, starch (with supplementary amylases), and TSE (with supplementary amylases and cellulases). The current study indicates that C. glabrata can be used for bioethanol production from glucose, polysaccharides, and complex starchy lignocellulosic substrates such as TSE via SSF.

Green industrial policies and domestic production of biofuels: an econometric analysis of OECD countries

The purpose of this paper is to investigate the relationship between green industrial policies and domestic biofuel production among OECD countries. The analysis builds on a data set including 24 OECD countries over the time period 2000–2016. This panel is estimated using a variant of the so-called Poisson pseudo-maximum-likelihood model and includes the mix of demand-pull (biofuel blending mandates) and technology-push policies (government R&D), as well as the interaction between these two types of instruments. The results suggest a positive relationship between blending mandates and domestic biofuel production. Thus, a more stringent blending mandate does not only increase the use of biofuels, but also domestic production (as a share of total fuel use). Government R&D has not, however, induced domestic biofuel industrialization processes. The results even suggest a negative interaction effect between government R&D and blending mandates, in turn implying that these two polices target different technological fields. The blending mandates tend to primarily favor commercialized first-generation biofuels, while government support to biofuel R&D has instead been focused on advanced biofuel technology.
