“…The cleaned water is re-used for managing the growing medicinal plant species at the AMBG. This has helped a great deal with the perennial water shortages earlier experienced at the university and with this research, comes to the hope of not only environmental conservation [19] but also economic gain through the use of harvested E. crassipes as raw material for the production of biofuel briquettes.…”

“…Economic utilization as a management strategy has been therefore encouraged worldwide. For instance, the positive use of the weed in the generation of farm fertilizer [12], production of bioethanol [13][14][15] substrate for mushrooms [16], generation of biogas energy [5,7,17] and remediation of polluted water [3,18,19] has been widely reported worldwide. E. crassipes has proved an efficient tool in cleaning sewage water as it absorbs nitrogen, phosphorus and other nutrients [19].…”

“…E. crassipes has proved an efficient tool in cleaning sewage water as it absorbs nitrogen, phosphorus and other nutrients [19]. The younger plants uptake the nutrients at a faster rate, which decreases as the tissues become saturated [19]. The saturated older plants need to be regularly harvested to ensure the efficiency of the sewage cleaning system through maximum nutrient absorption.…”

Harnessing the potential of common water hyacinth as an industrial raw material for the production of quality biofuel briquettes

Eichhornia crassipes has a high cellulose and hemicellulose content, which are easily converted to simple sugars, thus making the plant suitable for the production of biofuel briquettes. The main purpose of this proposed work, therefore, was to investigate the production of bio briquettes from E. crassipes. The plant was harvested from a wastewater effluent management system, chopped, sun-dried and pulverized to a particle size of < 5 mm and mixed with various binders (Eucalyptus globulus leaves powder, molasses and phytoplankton scum). The binders were appropriately prepared and added to E. crassipes at the ratios of 10%, 20% and 30%. The quality of biofuel briquettes was evaluated using compressed density, relaxed density, water resistance, durability and calorific values (CV) parameters and compared to those of charcoal briquettes already on the market. The results showed a water resistance capacity of 45%, relaxation ratios of between 1.08 and 1.33, CV of 1148.35 kJ/kg for 20% molasses-based briquettes, CV of 1090.43 kJ/kg for 20% E. globulus leaf-based briquettes and CV of 1422.97 kJ/kg for charcoal-based briquettes. In conclusion, therefore, E. crassipes may become a viable raw material for producing quality biofuel briquettes that are durable with the desired calorific value and may be able to withstand mechanical handling and be useful for household and cottage industries locally.
