Hexane Oil Extractor
In this project, ESW was collaborating with BAAN (Biofuels Action Awareness Network) using space provided by the Department of Chemistry and Biochemistry at UCSD. The purpose of this project was to create a machine that uses hexane to efficiently extract oil from used coffee grounds collected from campus coffee shops. This extracted oil can then be used as fuel or converted into biodiesel. After the oil extraction process, ESW will be donating the leftover coffee grounds to the Neighborhood Garden, located behind the Che Cafe, to use as fertilizer.
Current State and Future Goals:
The extractor has been built and we are now in the testing phase of the project. The objective at this point is to run the extractor without feedstock to determine if the extractor can run a complete cycle. If this fails, we will be adjusting the structure until a cycle can be completed. Test runs with feedstock will be conducted to determine how many cycles are necessary in order to reach optimum extraction.
With hopes of having a functional oil extractor, ESW plans to provide oil for anyone in need by taking materials that would otherwise be thrown away and extract oil from it for later use a fuel.
This project is currently on hold until further notice.
Funding for this project was provided by UC San Diego - The Green Initiative Fund.
