Our Story

We are more than just a waste business

The Journey

Zijani was founded in 2014, previously known as Biogen Diesel Kenya Limited, to commercialize biodiesel production and refining, with a focus on fuel quality and environmental sustainability. In November 2014, we opened Kenya's first biodiesel research and development refinery in Nairobi, Kenya which was capable of producing  up to 13,000 liters per year. We have grown and currently on course to produce 48,000 litres of Biodiesel per year from May 2017

In 2016, we completed our specialist biodiesel plant in Nairobi Kenya. Capable of producing 50,000 litres of biodiesel Per Year. It is Kenya’s first purpose-built plant dedicated to producing biodiesel from used cooking oil. ¬†This has allowed us to step ever closer to achieving 100% resource recovery by producing a biodiesel that saves over 95% Green House Gas emissions compared to fossil fuels. 

Today, Zijani aims to be the national leader in next generation biofuel production.
We are driven by two ambitious goals

  • to fundamentally service the food industry business by offering close loop waste solutionsTo meet our goals,
  • To continuously develop proprietary technology and processes across the entire food industry value chain.
