Problem Statement

Challenges with Waste Cooking Oil (WCO)

• WCO is a promising biofuel source due to itsavailability and environmental benefits.
• India produces an estimated 3 million metric tons of WCO every year and the figure is around 60% WCO found its way back into the food chain creating a very serious health risk to the consumer.
• Variability in chemical composition from different sources (fast food to gourmet) complicates SAF production.

​

Health Risks

• Approximately 60% of India's annual WCO (~3 million metric tons) is recycled back into the food chain, posing health threats.

​

Rising Demand for Sustainable Aviation Fuels (SAF)

• Environmental policies are driving the aviation sector to seek alternatives to conventional fuels.

Proposed Methodology

Social Impact

Health Benefits

• Reducing the recycling of WCO back into the food chain mitigates health risks associated with degraded oils.

​

Environmental Sustainability

• Converting WCO into SAF supports renewable energy initiatives and reduces greenhouse gas emissions in aviation.

​

Economic Opportunities

• Improved WCO collection and processing can create jobs and stimulate local economies through green energy initiatives.

​

Awareness and Education

• Promoting the benefits of SAF and responsible waste cooking oil disposal can enhance public awareness and participation in sustainable practices.
