Sir in response to the clarification, the investor has enclosed a link of website wherein it has been mentioned that

“Novozymes announces the launch of the Spirizyme® T Portfolio, an advanced suite of glucoamylase enzymes with trehalase and other yield enhancing activities that provide the most total sugar conversion in the industry.
Trehalase is an enzyme that converts trehalose, a type of sugar that cannot be fermented to ethanol, to glucose, which is easily fermentable. Trehalose makes up a significant part of the so-called DP2 peak, a measure of residual sugar in an ethanol plant. The more DP2 an ethanol plant can convert; the more ethanol it will produce.
Extensive plant trials of Spirizyme T showed that it reduced the amount of residual DP2 by up to 70 percent, the most in the industry. This would allow a 100 million gallons per year (MGY) plant to convert 11 million pounds of otherwise wasted sugar to approximately 700,000 gallons of additional ethanol per year. At current prices, this would add nearly $1 million in revenue for the plant.
Spirizyme T is available in three versions:
Spirizyme Ultra T has the best DP2 reduction vs. cost
Spirizyme Excel T has the lowest total residual sugar for short fermentation times
Spirizyme Achieve T has the greatest ability to reduce residual starch and sugar.
“Reducing residual sugar is key to raise profitability at an ethanol plant. Don’t leave your sugar behind,” says Peter Halling, Vice President – Biofuel, at Novozymes. “The Spirizyme T portfolio provides significant DP2 reduction across the board and offers our customers choice. There are options for plants with specific operating conditions, and plants looking to achieve particular goals, such as shorter fermentation or increasing total yield.”
What is DP2?
Ethanol is produced by the fermentation of sugar by yeast. Commercial production of fuel ethanol involves breakdown of starch in corn or other feedstocks into simple sugars, fermentation of these sugars by yeast, and finally recovery of the ethanol and byproducts (e.g. animal feed).
Unfermented sugars go to waste, and ethanol producers are therefore interested in technologies that increase efficiency. After fermentation, ethanol plant managers will run High-Performance Liquid Chromatography (HPLC) tests to measure the amount of residual sugar. The test measures four types of sugars: DP1 (single sugar chains such as glucose), DP2 (two-sugar chains such as trehalose), DP3 (3-sugar chains) and DP4 (everything else).
Reducing these sugar “peaks” is key to maximize ethanol production. At a typical ethanol plant, approx. 70 percent of DP2 is unfermentable trehalose, so by converting trehalose to a fermentable sugar you can increase yield considerably. That is what the enzyme trehalase does.”
In the opinion of undersigned, it is at a very advanced stage and without implementing the same as a trial in the plant, it cannot be inferred that it will give enhancement in production upto 28 percent.
Thus, in order to see the impact of use of such enzymes for enhancement in production of ethanol, it is recommended that Consent to Establish for Expansion for increasing the production capacity of Ethanol (Bio Fuel) from 125000 Liter/day to 160000 Liter/day within existing premises by using Damaged Grains @ 340 Metric Tonnes/Day, Enzymes @ 120 Kgs/day, Yeast @ 53 Kgs/day & Urea/DAP (Only during start-up) @ 700 Kgs/day as raw materials, be issued upto 14.05.2025, subject to conditions as mentioned in the note of AEE (PBIP), be taken please.
