  • APSC 261 - Technology and Society I
    APSC 261 - Technology and Society I An Investigation into Fuelstock Production in the UBC Farm to Create Energy and Reduce Greenhouse Gas (GHG) Emissions Tutorial Instructor: Ms. Saloome Motavas Team Members: Wei-I (Winnie) Tseng, Sze Wah (Christy) Lui, Guanpeng (Justin) Li Date of Submission: November 28, 2013 ABSTRACT The project is to investigate the best plant as fuelstock that can be grown in UBC Farm, which is a 24 hectare farm on the southern end of the University of British Columbia (UBC). The Triple Bottom Line method is implemented during the entire investigation. Since several fuelstock options can be grown in UBC farm, the best candidate should chosen based on economical, ecological and social indicators. The result is derived by estimation since all data are collected from other papers and online resources. The economic indicators include input costs and profit generated by trading Miscanthus with the Bioenergy Research Demonstration Facility (BRDF). The ecological indicators applied are reusability of existing space and materials, improvement in environmental condition, protection from environmental degradation and increase in sustainable practice. Also, the social indicators consist of potential job increases, improvement of relations across sectors and providing educational opportunities. The result shows that Miscanthus is the best option and is highly recommended. Although the UBC farm may not provide the enough land to grow Miscanthus and supply the entire operation of BRDF, the pattern and model can be transferred to other parts of British Columbia (BC) and be implemented. In short terms, there is money input to the project, however, from long run perspectives, society and ecology environment will benefit of low greenhouse gas(GHG) emissions.

Although ethanol is the dominant liquid biofuel globally, technical restrictions limit its use in convention- al gasoline cars to 10–15 v/v% (bio-energy 7–10%). Since current conventional cars will continue to take the major share of gasoline car fleets for at least the next 10–20 years, it is necessary to establish and assess biocomponent options for them. Today, higher ethanol blending ratios are possible only with the use of flexible fuel vehicle (FFV) technology. The European Union requires renewable energy to have at least a 10% share of transport energy by 2020, and even higher shares are being attempted regionally.
