Exploration of Avocado Oil Extraction Methods and Potential in Rural Tanzania
- Student Papers
This project is a continuation of a challenge first explored at IDDS 2014 in Tanzania—the fact that excess avocado crops often go to waste in rural villages in East Africa. Its authors visited Tanzania to explore avocado oil extraction methods and market potential for avocado oil.
Design, Construction, and Testing of a Mango Juice Extractor
- Student Papers
This paper details the design, construction, and testing of a mango juice extractor built to minimize post-harvest food loss in mango crops in Ghana and other mango-producing countries.
Standardization of the Grating Surface of Cassava Graters
- Student Papers
This paper explores an effort to standardize the design of a cassava grating surface to improve efficiency and ensure interchangeability. The author surveyed cassava grating surfaces on the Ghanaian market to understand current technical specifications and then create a new, improved grating surfaces using locally available materials.
Design, Construction, and Testing of a Briquetting Machine
- Student Papers
This paper explores the design, construction, and testing of a briquetting machine produced for rural communities in Ghana. In Ghana, biomass is the most dominant source of energy and is used significantly for cooking and other heat applications.
Design, Construction, and Testing of a Biocharring Unit
- Student Papers
This paper explores the design, construction, and testing of a biocharring unit. Biochar is obtained by heating biomass under oxygen-deficient conditions, and has potential as a nutrient recycler, soil conditioner, income generator, and waste management system.
