The concept of the Index Green Energy biorefinery focuses on achieving maximum sustainability and CO2 efficiency in the production of biofuels. The biorefinery concept is centered around closed cycle systems and utilizing the entire plant for biofuel production. It is the first large-scale biorefinery in Africa that combines a biomethane, bioethanol, and biofertilizer plant.
Through the utilization of raw materials twice, we are able to achieve exceptional efficiency and reduce CO2 emissions. Over 90% of the raw materials used are converted into bioethanol and biomethane (referred to as index green gas) to generate energy. The remaining inorganic components are recycled as biofertilizers, contributing to sustainable agriculture practices.
This interconnected system allows for more than doubling the energy yield from one hectare of land compared to current biofuel production processes.
This system network offers several benefits over conventional bioethanol systems. Firstly, it provides a 40% higher energy yield from the raw materials utilized, resulting in increased efficiency. Secondly, the energy consumption within this network is approximately 40% lower, contributing to reduced resource usage. Additionally, the biofuels produced through this process result in CO2 savings of up to 90% when compared to gasoline and diesel, taking into account the entire value chain. This emphasizes the environmental advantage of the system, as it significantly reduces greenhouse gas emissions.
