“…Another important issue is the rebound effect. For instance, Hochman et al [50] found by their modeling work that the introduction of biofuels increases the amount of total fuel consumed and reduces the average fuel price in South Korea. Therefore, there is an environmentally damaging recovery in which gasoline consumption is reduced by less than the quantity of surplus biofuels.…”

Economic and Sustainability of Biodiesel Production—A Systematic Literature Review

As Earth’s fossil energy resources are limited, there is a growing need for renewable resources such as biodiesel. That is the reason why the social, economic and environmental impacts of biofuels became an important research topic in the last decade. Depleted stocks of crude oil and the significant level of environmental pollution encourage researchers and professionals to seek and find solutions. The study aims to analyze the economic and sustainability issues of biodiesel production by a systematic literature review. During this process, 53 relevant studies were analyzed out of 13,069 identified articles. Every study agrees that there are several concerns about the first-generation technology; however, further generations cannot be price-competitive at this moment due to the immature technology and high production costs. However, there are promising alternatives, such as wastewater-based microalgae with up to 70% oil content, fat, oils and grease (FOG), when production cost is below 799 USD/gallon, and municipal solid waste-volatile fatty acids technology, where the raw material is free. Proper management of the co-products (mainly glycerol) is essential, especially at the currently low petroleum prices (0.29 USD/L), which can only be handled by the biorefineries. Sustainability is sometimes translated as cost efficiency, but the complex interpretation is becoming more common. Common elements of sustainability are environmental and social, as well as economic, issues.

“…The developed model was then applied to a case study in South Korea, where the current demand for bioethanol is 350 million gallons per year (MGY), to show (a) the optimal mix of feedstocks required for a biorefinery and (b) the optimal supply chain configuration (e.g., the best depot locations, required depot numbers, and sizes). In South Korea, forecasting models have predicted that there will be an annual production of approximately 37 million tons of oil-equivalent renewable energy by 2035, including bioethanol and biodiesel …”

As the global climate crisis worsens and fossil fuels deplete, renewable energy sources have become more appealing. Biofuel is one of the promising sources produced from multiple biomass sources, as long as it does not compromise food security. In this direction, a multiperiod mixed-integer linear programming model incorporating three types of biomass simultaneously is developed to provide a second- and third-generation biofuel supply chain. The proposed model minimizes the total annualized cost by selecting raw materials, locating production facilities, placing storage facilities, and identifying optimal material flows by defining a deference path for each feedstock. A case study addressing bioethanol production in South Korea was then conducted to evaluate the performance of the developed model; the results demonstrated a clear reduction in the total annualized cost by incorporating multiple feedstocks. Using multiple feedstocks allowed for the total ethanol demand of South Korea to be met using harvested biomass, thereby drastically reducing import costs. Refinery costs accounted for the large majority of the remaining costs. A sensitivity analysis was also conducted to assess the effect of uncertainty associated with some economic and production parameters.
