like nonsense; it wakes up the brain cells — Dr. Seuss

Although the water lily has many uses amongst different peoples of the world as food and shelter, it however, can become a weed, blocking out sunlight and oxygen from the water, displacing local aquatic plants and posing a danger to water transportation. Due to its extremely rapid proliferation, it presents serious challenges, especially to Nigeria. 

Having observed the devastating effects of the invasive water lily on Nigerian waters, the ‘nonsense’ woke up the brain cells of the trio of Dr. Naomi John Dadi-Mamud, Dr A. Gudugi and Dr. R. L Nginga of the Ibrahim Badamasi Babangida University, Lapai, Niger State and they decided to create something good out of the bad and at the same time, solve the problem of rural energy supply. Vanguard Learning presents the work of three scientists at IBBU.  Read on:

THE research: According to Dr. Naomi John Dadi-Mamud, “over 85 per cent of the world rural population depends on biomass in the form of wood and plant residues for domestic purposes, causing deforestation resulting to environmental degradation. Therefore, to solve the energy crises in our country, biogas production is important.

Biogas

“As biogas technology provides an environmentally sound means of managing animal and plant wastes. Unlike water hyacinth that had been used for biogas production, Water lily from the same family, has not been used for biogas production from known literatures,” said Dadi-Mamud.

 

Method

They collected the water lily; cut them up, poured them into a digester; removed the substrates from digester.

The gas was produced in a gasometer (gas holder).

“The procedure of biomethanation, fermentation and pyrolysis was adopted for the conversion of the aquatic plant to produce biogas.

“Gas Chromatography equipped with a thermal conductivity detector was used for the qualitative and quantitative analysis of the different components of the substrates.”
