“…Both plants are assumed to have a working life of ten years. In both cases the use of fossil fuels is the largest impact; predominantly associated with the production of methoxide, this finding is consistent with other publications in this area, for example Morais et al [10]. This is because methanol is made from either natural or coal gas.…”

Abstract:The UK transport sector is currently responsible for 30% of UK CO 2 emissions. Therefore, the use of biofuels is explored. As the CO 2 released when energy is generated from biomass is generally balanced by that absorbed during the fuel's production it is often regarded as a 'carbon neutral' process. However, there are impacts associated with bioenergy production, including, for example, the growth and transportation of feedstock. One way to overcome these is to use a waste oil feedstock. Whilst there will not be enough waste oil to meet all our fuel demands, some firms in the UK have started to use their waste catering oil for transport. Collection and conversion is often done on a small scale and a number of methods are used for the processes. Therefore, the associated environmental impacts are variable. The environmental impact of the production and use of biodiesel from waste oil based on two case studies has been assessed. The impacts associated with the use of fossil fuels and climate change gas production is lower than that of the production of conventional fossil fuel diesel. The biggest impact within the process is associated with the use of methanol and the waste oil collection.

“…The principles of extraction were used to advantage in everyday life, for example in making juices, coffee and others. To reduce the use of organic solvent and improve the extraction methods of constituents of plant materials, new methods such as microwave assisted extraction MAE , supercritical fluid extraction SFE , accelerated solvent extraction ASE or pressurized liquid extraction PLE and subcritical water extraction SWE , also called superheated water extraction or pressurized hot water extraction PHWE , had been introduced 42,43 .…”

The life cycle analysis of biodiesel production from palm oil (PO) involves 3 stages: 1) Cultivation; 2) Oil Extraction and 3) Transesterification of PO. There are several different approaches to the production process. The enzyme catalyzed process, was investigated and its environmental performance was compared with the conventional alkali-catalyzed process by using life cycle analysis (LCA). The enzyme catalyzed process is found to be technically a simpler production process and offers the production of less environmentally damaging wastes.
