An initial test was conducted to evaluate methane gas production from water hyacinth collected from the wild. After a successful production of biogas, laboratory experiments were initiated with the aim of generating biogas from aquatic macrophytes (water hyacinth) grown in the laboratory.

Experimental ponds were constructed within the Botanical Garden, Faculty of Life Sciences, University of Benin. The biogas production unit was located in Centre for Energy and Environment, University of Benin, Benin City.
