James Murichu's passion for innovation saw him immerse into diesel making, after studying the chemistry behind it. In collaboration with his colleague Michael Nthenge, the two read books and used their knowledge to recycle plastic waste and manufacture petrol and diesel. Murichu uses the diesel to drive his car, while petrol is used in smaller engines such as water pumps, power saws and generators. Murichu spoke to Citizen Digital on how he concieved and actualised this idea.
