Biofuels; this renewable source of energy is gaining popularity all over the world to fulfil the global energy requirements. In Europe, including the UK, biofuel is used as liquid transport fuel. However, it is not used as widely as what people estimate. Therefore, the world is facing the problems of harnessing of renewable energy resources, and there are greater concerns about the emissions produced by burning of fossil fuels, such as petroleum and coal, it’s use is unquantifiable and hampering the world’s living ecosystem.
Accomplishing the ever increasing demand of energy and to mitigate the problems of climate change by reducing GHG emissions from transport fuel and to promote fuel security and reduces the imports of fuels from energy rich countries, European Union has formulated Biofuel Directive (2003/30/EC) stating that the member states will implement this policy to include at least 5.75% of biofuel in the fossil fuel and increased the recent scenarios of 7% to 20% by 2020. Supporting the directive, the UK government has formulated RTFO policy to implement to reduce the use of fossil fuel by 5% in 2010 and follow the process to obtain the renewable target.
Basically, this study focuses on the Life Cycle Analysis (LCA) of biofuel crops as a source of biofuel, such as biodiesel and bioethanol to be used in transportation sectors to meet the renewable target by reducing the GHG emissions and imports of fossil fuel. The subject of the study also gives an overview of the comparative study of the impacts of growing biofuel crops in Nepal and in the UK on environmental and socio-economic issues, like impacts on land, water, biodiversity, and food and energy security.
At the outcome of the study, will it be helpful to coin similar model to RTFO in Nepal and gives hint how the model is unfair to implement in Nepal.

Research Objectives and Themes
This study examines the viability of implementing a Renewable Transport Fuel Obligation (RTFO) model in Nepal, similar to that used in the UK, to reduce greenhouse gas emissions and dependency on fossil fuel imports. By applying Life Cycle Analysis (LCA) to biofuel crops like oilseed rape and sugarcane, the research compares the environmental and socio-economic impacts within both nations, specifically focusing on energy security, food availability, and the challenges of agricultural mechanization.
- Life Cycle Analysis (LCA) methodology for biofuel production chains.
- Comparative environmental assessment of UK and Nepalese biofuel feedstock production.
- Socio-economic implications of converting agricultural land to energy crops in developing economies.
- Energy security and GHG emission reduction targets via liquid transport biofuels.
- Technical and infrastructural limitations for implementing large-scale biofuel policies in Nepal.
Excerpt from the Book
5.1.5 Oil Extraction
Seeds do vary a lot in their oil content and physical size. The oil extraction process must be optimized for every type of seed. The residues remain after oil extraction is called meal or cake. Every oil extraction process heats up the oil in some way due to friction. But the temperature above 150ºC is not considered good as it destroys the protein and vitamin E in both the oil and meal. Lower temperatures (50-70ºC, cold press) do not damage the oil or meal significantly; however, it reduces the yield, making good oil a lot more expensive.
Following processes are used while extracting oil:
Expeller pressed: In this case, oil is obtained by squeezing the seed, at pressures up to 15 tons/square inch. The higher the pressure, the more heat is generated. But at extremely high pressure, the temperature can exceed 150ºC. The steam is used to increase yield and destroy enzymes which will break down the oil into free fatty acids. The resulting meal can undergo the solvent extraction process.
