Abstract

Water hyacinth is an aggressive weed that invades the water bodies. It causes reduction of biodiversity, blockage of rivers and drainage system and depletion of dissolved oxygen. Attempts to exterminate or control this weed using modern technology such as those of mechanical, biological and chemical means of destruction have failed. The plant continues to survive and proliferate. A number of studies have been made on the utilisation of this weed for various applications. This paper presents an overview of the literature collected on the application of water hyacinth as a source of biogas production.
