Cassava Waste Management and Biogas Generation Potential in Selected Local Government Areas in Ogun State, Nigeria
Abstract
:1. Introduction
- find out the method of waste disposal that is adopted by cassava processors in the selected local government areas,
- find out what cassava residues are used for in the selected cassava-processing factories,
- find out the factors that influence processors’ willingness to pay for an improved waste management system, and
- investigate if cassava wastes generated in the selected local government areas have the potential for the generation of biofuel.
2. Materials and Methods
2.1. Sample Size and Sample Technique
2.2. Reliability of Instruments
3. Results and Discussion
Biogas Production Potential
4. Conclusions
5. Recommendations
- That proper waste disposal methods should be adopted by the cassava processors in Ogun State to minimize pollution and reduce health risks.
- There is a need for awareness of the income generation potential of cassava waste among the cassava processors in Ogun State.
- It is highly recommended that the waste water generated from cassava processing undergoes proper treatment before it is discharged.
- Based on the biogas generation potential of the cassava-processing factories in Ogun State, it is important that this resource be harnessed.
