“…The advantages of using biodiesel compared to mineral-derived diesel fuel include reduced exhaust emissions, promising alternative of mineral based diesel fuel, improved biodegradability, reduced toxicity and improved lubricity, higher flash point, and lower vapour pressure [11,12]. High oil prices and the need to reduce greenhouse gas emissions make investment in biofuels desirable [13]. According to Scarisbrook and Ferguson [14], the most important advantage, which may well become the dominant factor with the passage of time, is the fact that such…”

Hura crepitans Seed Oil: An Alternative Feedstock for Biodiesel Production

Oil was extracted from the seed ofHura crepitansusing hexane in a soxhlet extractor and analyzed for iodine value, saponification value and free fatty acid content. The dominant fatty acid in the oil was C18:2 (52.8±0.10%) while the iodine value was120.10±0.70 g iodine/100 g. Biodiesel was produced from the oil using a two-step reaction system involving a first step of pretreatment via esterification reaction and a second step via transesterification reaction. The pretreatment step showed that free fatty acid inHura crepitansseed oil can be reduced in a one-step pretreatment of esterification using H2SO4as catalyst. The biodiesel produced fromHura crepitansseed oil had an acid value of0.21±0.00 mg KOH/g, flash point of 152 ± 1.10°C, copper strip corrosion value of 1A, calorific value of39.10±0.30 mJ/kg, cetane number of45.62±0.30, and density of0.86±0.02 g cm−3. The process gave a biodiesel yield of98.70±0.40% with properties within the recommended values of EN 14214.

“…Fiscal policies are under constant scrutiny because they are considered expensive by some authors (Jatzke, 1994;Saikkonen, Lankoski, & Ollikainen, 2012;Singh, 2006). Thus, the decision on whether or not to support a bioenergy project through public funds, or by applying tax exemptions, heats up the debates around cost-efficiency.…”

Production of biofuels for transport in Colombia

Bioenergy has emerged as a potentially sustainable alternative to the use of fossil fuels for transport and industrial uses. Developing nations, such as Colombia, can seize the advantages of modernizing rural areas by using cleaner energy and having more economic opportunities with bioenergy initiatives, provided the trade-offs between fiber, food, feed and fuel can be managed. This Thesis examines the bioenergy program now under way in Colombia, where comparative advantages (shared with other tropical countries) in production of sugar cane and palm oil are being built on. While the technologies associated with use of these feedstocks are well known, nevertheless their scaling up in a country like Colombia poses considerable environmenral, social, economic and business challenges.
