4.2.2 Limitations

• With this project, the main constraint, once the facility was set up, was to procure the water hyacinth outside the state.
• There were gas leakages that could lead to reduction of the gas since they were made by hand.
• The experiment was greatly affected by the weather because it needed a high temperature for gas production resulting in a smaller quantity of gas. (Low gas production during cool season)
• The experimental set up wasn’t available so it had to be made from scratch which resulted in patching some areas with adhesives.
