Der Anbau verschiedener Agrarrohstoffe, wie beispielsweise Palmöl und Soja, steht häufig in Verbindung mit der Abholzung von artenreichen tropischen Regenwäldern mit hoher Kohlenstoffspeicherkapazität. Diese sogenannten „Waldrisiko-Rohstoffe“ werden über internationale Lieferketten...

Purpose: The purpose of this case study is to develop and framework supply chain characteristics and risk mitigation strategies in the context of biodiesel downstream supply chain. Design/methodology/approach: This study employs an expert interview-based approach as a qualitative approach with a...

In face of increased efforts to mitigate climate change, biofuels may be included in reduction plans forgreenhouse gas emissions. Feedstock for first generation biofuels and food crops both use arable land andmay compete for it. Also, fuel is an input for the production and transport of food....

The global transport sector is the second largest energy consumer and strongly relies on fossil fuels. Efforts for reducing GHG emissions on this sector depend on energy efficiency improvement and the use of renewable fuels and electrification. All these technologies are commercially available...

This article investigates the connections between the prices of biofuels and many traded commodities and other relevant assets in Europe, USA and Brazil. The analysis uses a comprehensive dataset covering price data for 38 traded titles over the period 2003-2020. We utilize the minimum spanning...

This paper summarizes the main findings of the results in the literature on the role of ethanol in reducing retail gasoline prices in the United States. We provide a comprehensive overview of the key results and methodologies used to obtain them. The paper documents the growing research interest...

Bioenergy is an economic and ecological alternative energy, derived from biomaterials such as bioethanol, biomass, biodiesel etc. Therefore, biodiesel is a renewable and biodegradable fuel could be manufactured from vegetable oils, animal fats, or recycled restaurant grease. Traditionally world...

The Government of Indonesia has been promoting the advancement of the biodiesel sector to fulfill its commitment to support clean energy, energy security, and rural development. This paper examines the economic impact of the biodiesel sector using a computable general equilibrium model. Besides...

5-(Hydroxymethyl)-furfural (HMF) is a platform molecule obtained by dehydration of hexoses, product of the hydrolysis of residual lignocellulosic biomass. By etherification with ethanol, 5-(Ethoxymethyl)-furfural (EMF) can be obtained, a promissory bio-additive for diesel. The etherification is...

Flexible and wearable energy devices have become an important support and indispensable product of the era of artificial intelligence and Internet of Things. Enzyme biofuel cells (EBFCs) have received much attention for their ability to convert the body's abundant biochemical energy into...

Although microalgae biofuel has many advantages, it is also faced with difficulties in algal cell harvesting and low lipid content. In this experiment, the mixtures of seawater and domestic sewage were prepared for the cultivation of freshwater microalgae. The results showed that the proportion...

The effort to implement more environmental-friendly fuels has been enhanced not only to reduce the greenhouse effect but also for public health issues. This paper studies the effects on pollutant emissions from a light-duty Euro 6 vehicle of four types of fuel: diesel (fossil origin, used as...

Ethanol is one of the most promising bio-based renewable platform chemicals. Catalytic upgrading of ethanol into valuable products instead of gasoline additive is of great importance, and co-production of hydrogen and acetaldehyde via the dehydrogenation of ethanol is an effective way for its...

The toxic nature of acyl acceptors to biocatalyst is a major concern for an efficient transesterification process. In this study, bio-esterification of Soybean Cooking Oil Waste (SCOW) for biodiesel production using free and glyoxyl-agarose immobilized lipases from Aspergillus oryzae and the...

A catalyst based on MoO 3 was synthesized by a simple and fast pilot-scale combustion reaction method and applied to the conversion of soybean oil to biodiesel via transesterification. For that, the statistical analysis of the catalyst amount and temperature, factors that influence the process,...

Microalgae are one of the sources of biodiesel production. In this paper, Dunaliella tertiolecta species were studied. The highest biomass production was 1.04 g/L, but the optimal biomass production and cost were 0.84 g/L for 1.48 cents/liter. The biomass to bio-oil extraction (BBE) section was...

In this work, the heterogeneous catalytic production of 2,5-dimethylfuran (DMF) and 2,5-dimethyltetrahydrofuran (DMTHF) in a fixed-bed continuous-flow reactor has been investigated. This study utilizes an unconventional biomass-derived carbon as the catalytic support for bimetallic NiCu...

Biogas upgrading to biomethane is a feasible option for greening the European energy sector, and specifically transport. Bio-CNG and bio-LNG fuels are considered a valid solutions for freight, and the European biomethane sector displays an interesting production potential, supported by a growing...

The latest Renewable Energy Directive (RED II) by the European Union (EU) provides an updated framework for the use of renewable energy in the EU transport sector until 2030. We employ the computable general equilibrium (CGE) model DART-BIO for a scenario-based policy analysis and evaluate...

Advanced biofuels are among the available options to decarbonise transport in the short to medium term especially for aviation, marine and heavy-duty vehicles that lack immediate alternatives. Their production and market uptake, however, is still very low due to several challenges arising across...

According to the official document of Romania's energy policy for the period 2020-2030, with a view to 2050, the main objective of the strategy is to increase the energy sector in conditions of sustainability by setting targets for reducing greenhouse gas emissions and promoting renewable...

Concerns about energy security, rural development, and the environment have driven biofuel expansion. Different policy and market drivers, such as designated areas for biofuel feedstock production and blend mandates, have played an important role in biofuel expansion in different countries....
