Mangalore Refinery and Petrochemicals Limited (MRPL), Indian oil & gas company based in Mangalore, is planning to build a second generation (2G) ethanol facility in the State of Karnataka (India). A local distributed model will integrate the gas fermentation technology of LanzaTech with the gasification technology from Ankur Scientific. 
Press release: “Advanced Biofuel Facility Gets Green Light in India”, 15/9/2020.

MRPL has awarded LanzaTech the contract to commence the basic engineering for an integrated processing facility to convert locally available agricultural residues to approximately 16 ktons/year (5.3 MGal/year) of fuel grade ethanol. To convert the solid biomass wastes to gases, LanzaTech will deploy commercially proven gasification technology from Ankur Scientific, a waste to energy company that specializes in distributed production, based in Vadodara (India). The resulting carbon rich gas will then be converted to ethanol using LanzaTech’s gas fermentation platform. 

The integrated technology will have the flexibility to process a wide range of biomass feedstocks enabling rapid replication at other locations. A by-product of the project will be a nutrient rich biochar. This will be used as a sustainable and low carbon source of fertilizer for the local community. 

The Indian Government is encouraging production of cellulosic ethanol from agricultural wastes and residues that would otherwise be burnt on the fields and create harmful pollution. Not only does conversion to ethanol create a new source of income for local farmers, it is also in line with the governments biofuels roadmap to increase production of 2G, non-food or feed based ethanol across the country to meet its 20% ethanol blending mandate by 2030.

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

Versión en Español Type of post: NEWS IN BRIEF.  Novozymes has launched Fiberex, a comprehensive platform based on novel enzymes and yeast strains to convert corn fiber into ethanol.  Press release: “ New biological platform converts corn fiber into ethanol ”, 16/09/2020.  Website: Fiberex® platform - Reimagining ethanol .  Related posts: “ Corn fiber ethanol – Examining 1.5G technologies ”, 26/4/2017. Figure 1. Fiberex platform (taken from the company website)  Typically, the starch in a corn kernel is converted into ethanol while the rest of the kernel ends up as low-value animal feed. In this remaining part of the kernel, there is a high amount of corn fiber with little to no value to the animals. Corn fiber is made up of similar building blocks as starch but is tough to break down and convert into something more useful. Fiberex is specifically aimed at breaking down tough fibers in the corn, providing producers with greater operational flexibility. ...

Publication date: 15/06/2017 Last update: 24/01/2018 Introduction 1,2,3,4,5 2,5-Furandicarboxylic acid (FDCA), also known as dehydromucic acid and pyromucic acid, is an organic compound that was first detected in human urine. In fact, a healthy human produces 3-5 mg/day. It is a very stable compound. Some of its physical properties, such as insolubility in most of common solvents and a very high melting point (it melts at 342 °C), seem to indicate intermolecular hydrogen bonding. FDCA has two carboxylic acid groups, which makes it a suitable monomer for polycondensation reactions with diols or diamines. It is one of the top 12 value-added biobased chemicals listed by the US DoE in 2004. The list was updated in 2010 and FDCA was included again, but this time in a group together with furfural and 5-hydroxymethylfurfural (5-HMF). Those three molecules are the main representatives of the furanics (furan derivatives) that has been referred to as “Sleeping Giants” beca...
