Sugarcane Juice for Ethanol Production - Coggle Diagram
Sugarcane Juice for
Ethanol Production
Central Idea
Reason: Expected drop in sugar production due to below-average rainfall.
Setback: Affects the government's target of 20% ethanol-blended petrol by 2024–25.
Government directive to sugar mills and distillers not to use sugarcane juice or sugar syrup for ethanol production in 2023–24.
Ethanol
Blending
Capacity: Approximately 9.5 billion liters (as of April 2023).
Production Source: Primarily from sugarcane molasses in India.
Renewable Fuel: Derived from plants, considered renewable.
Blended motor fuel containing at least 99% pure ethyl alcohol derived from agricultural products, blended exclusively with petrol.
Benefits
of Blending
E10 saves 20,000 tons of CO2 emissions.
Ethanol's oxygen content reduces environmental pollution.
E20 program estimated to save USD 4 billion per annum.
2G technologies can convert agricultural waste to ethanol.
Higher ethanol usage saves import costs.
Categories
of Biofuels
Third Generation: Sourced from algae.
Second Generation: Produced from sustainable non-food materials.
Fourth Generation: Involves advanced biotechnology.
First Generation: Derived from food sources (ethanol from sugarcane).
Challenges
Lower Efficiency: Calorific value of ethanol is lower.
Higher Cost of Vehicles: FFVs are more expensive.
Delays in Clearances: Ethanol production plants face delays due to environmental clearances.
Concerns of Industry: Additional investment required for FFVs.
Availability of Blended Fuel: Dependency on sugarcane, leading to fluctuating ethanol production.
Changes in Existing Fleet: Vehicles need modifications for E20 fuel.
Government
Initiatives
Modified Scheme for 1G Ethanol: Financial assistance for 1G ethanol from cereals and sugarcane.
EBP Programme: Aims to mix ethanol with motor spirit to reduce pollution.
Pradhan Mantri JI-VAN Yojana: Financial support for bioethanol projects.
Roadmap for Ethanol Blending: Expert committee report on blending by 2025.
National Biofuel Policy, 2018: Categorizes biofuels and supports advanced biofuels.
Repurpose Used Cooking Oil (RUCO): Converts used cooking oil to biodiesel.
GOBAR DHAN Scheme: Aims for wealth and energy generation from organic waste.
Way Forward
Expedite Clearances: Formulate a single window clearance system for ethanol production projects.
Support for Industry: Provide financial support for FFVs and technology development.
Diversification of Feedstock: Encourage production from low-water-consuming feedstocks.
Incentives for Customers: Lower retail prices for blended fuels to incentivize consumer switch.
Ensure Sustained Production: Augment sugarcane and grain-based ethanol production.
