enfinity® is Praj Industries’ proprietary, proven technology to responsibly produce sustainable, carbon-neutral advanced bioethanol and high-valuable co-products. enfinity® brings infinite possibilities for project configurations. The proprietary technology is highly feedstock flexible using cellulosic biomass from:
- Agricultural residues: wheat straws & rice straws, corn stover, bagasse, etc.
- Energy crops: miscanthus, elephant grass, etc.
- Hardwoods: Beech, Oak, Birch, etc.
With extensive biofuel industry experience, our multi-expertise R&D and engineering teams upgraded our proven 1G production technology to create the fully integrated advanced bioethanol technology enfinity®.
enfinity® is characterized by an industry-leading material handling and pre-treatment system. It is born out of Praj’s treatment solutions for complex 1G feedstocks like Cassava, which have similar characteristics such as cellulosic feedstocks, for example significant impurities of mud and sand as well as a comparable crystalline fibrous structure. Looking at the complete production process of advanced bioethanol, the upfront pretreatment is the key to determining the efficiency of the subsequent process steps especially of the enzymatic hydrolysis. In our 3 commercialized advanced biorefineries, we have realized enfinity® pretreatment system with cutting-edge efficiency, plant availability, lowest maintenance, and enzyme use cost.
Our Journey to the Multiple Commercial Scale Advanced Bioethanol Plants of enfinity®
We have been chasing our dream of sustainable and economical advanced bioethanol production for over two decades.
In 2009, our cellulosic pilot plant started operations in our R&D center Matrix. This facility has tested more than 450 MT of biomass such as straws from wheat & rice, corn stover, bagasse, etc from all continents.
In 2017, the demonstration facility for Praj Industries was inaugurated by India's Cabinet Minister of Road Transport, Highways & Shipping and is currently exporting its advanced bioethanol to the adjacent 1G bioethanol and sugar factory. This pre-commercial plant has proven high performance regarding robustness, high yield of operations, cost-effectiveness, and predictability of scale-up.
In 2022, India’s Prime Minister inaugurated the 1st enfinity® commercial-scale plant in Panipat – Haryana, licensed to the IOCL. The plant, co-located to India’s largest oil refinery, converts 128KMT per year of sustainably sourced, rice straw into 24 ktpy of advanced bioethanol. The industrial facility creates 1500 indirect and 200 direct employments and CO2 reductions of 320 ktpy, which equals taking 63K cars off the roads.
