Meet Ejikeme Patrick Nwosu, the Nigerian scientist who transformed urine into clean energy
One of his most remarkable contributions is a method to turn urine into flammable gases, along with other groundbreaking technologies.Former Vice President Yemi Osinbajo, speaking on behalf of then-President Muhammadu Buhari, praised him as one of six outstanding Nigerian inventors advancing science and technology.
He was also honored with the title “Anambra Person of the Week.”
Early Life and Education
Ejikeme Nwosu was born in Awka, Anambra State, Nigeria. He studied pure and industrial chemistry at Nnamdi Azikiwe University. He later earned a master’s degree in organic chemistry from the University of Ibadan. His education equipped him with the knowledge to pursue his innovative ideas.
Inventions and Patents
Urine-to-Energy Technology: Nwosu patented a process for isolating ammonia from urine using a device he called the patrium flask reactor. This method produces flammable gases, offering an innovative energy source.
Fire Retardant Paint: He developed a fire-resistant paint that prevents objects from burning, enhancing safety in high-risk environments. Separation Apparatus: Nwosu created a device to purify mixtures of solutes, solvents, and colloids, demonstrating his skill in chemical innovation.
Urine-Based Fertiliser He also developed fertiliser from human urine. To make this possible, he designed a prototype urine-diverting toilet that collects urine for processing. This invention earned him another Nigerian government patent in November 2022.
Collaborations and Applications
Partnership with the Nigerian Government: In 2021, Nwosu’s company, Lumos Laboratories Nigeria Limited, partnered with the Federal Government. Together, they launched a waste management system that turns biodegradable waste and urine into biogas. This biogas is now used to produce electricity and cooking gas in correctional centers across Nigeria.Collaboration with Hydrofuel Canada Inc.: In 2022, Hydrofuel Canada Inc. signed an agreement with Lumos Laboratories. The partnership aims to produce green hydrogen, ammonia, fertiliser, and electricity using human and animal waste.
