Palm kernel shells are produced as waste from palm oil and are utilized by blacksmiths after they have been charred to burn off the remaining oils in them. This KNUST student thesis analyzes the calorific value of palm kernel shells used during this process.
This KNUST student thesis evaluates a mechanized rice thresher developed in Konongo, Ghana on the parameters of capacity, efficiency, optimum speed for threshing, and fuel consumption.
This KNUST student thesis analyzes the threshing speed, threshing losses, drugery, threshing efficiency and threshing capacity of two rice threshers produced in Ghana: a hand-operated and a foot-operated thresher.
This KNUST student thesis presents results on biogas production from mixtures of fruit and vegetable waste materials and a mixture of fruit and vegetable waste materials.
This KNUST student thesis determined the quantity of coconut waste generated and assessed coconut waste usage and management in the Kumasi Metropolis.
This report was prepared by students in the Fall 2015 D-Lab: Field Research class to provide Zasaka with research design recommendations for their impact evaluation research.
Trash is a big problem in Sao Paulo, Brazil. UC Davis students Ryan Pang and Daniel Quinn from D-Lab have worked to design and prototype a PET Bottle Strip Cutter for Miguel Chavez in the Innovation Center-Vila Nova Esperanca. The problem with the existing bottle strip cutter currently used by the center is that the design will not allow for adjustments to be made in the size of the plastic string created and is not set up for different sized plastic bottles. Cutting bottles into strands of plastic is important because the string can then be woven to make items such as chairs, green houses, fencing, and more. These products can generate income to improve the lives of people living in poverty. Additionally, in improving this design we can decrease the amount of plastic trash accumulation by repurposing it to create desirable goods.
This is the presentation abstract of a research project on improving the efficiency of cassava graters. The author surveyed existing cassava grating surfaces on the Ghanian market and then designed and tested three new grating surfaces. The project was presented at KNUST in July 2015.
This paper continues the previous research of the author, in which the author surveyed cassava grating surfaces on the Ghanian market. The author designed and tested three new grating surfaces to improve efficiency and ensure interchangeability of the cassava graters.
This paper continues the previous research of the authors, in which structural failures of aluminum pots cast by Zambian businesses were evaluated. The authors then explored how local practices can be improved to prevent common use failures.
