The Karnataka State Bioenergy Development Board (KSBDB) has urged the Centre to formulate a comprehensive national policy to prevent the unauthorised reuse of used cooking oil and promote its systematic collection for biodiesel production, Deccan Herald reported.
KSBDB chairman S E Sudheendra raised the issue during a meeting with Union Minister of State for Home Affairs Nityanand Rai on Wednesday, submitting a memorandum highlighting the health and environmental risks associated with the improper handling and disposal of used cooking oil.
The memorandum noted that hotels, restaurants and food establishments often reuse cooking oil multiple times, leading to oxidation and the formation of harmful compounds, including aldehydes. Consumption of food prepared using degraded oil could pose serious public health risks, making stricter inspections, monitoring and enforcement of food safety standards necessary.
The improper disposal of used cooking oil into drains and water bodies also contributes to sewage blockages and environmental pollution.
Sudheendra called for treating used cooking oil as a valuable raw material rather than waste, highlighting its potential to support biodiesel production, generate employment and advance India’s renewable energy objectives.
The memorandum recommended national guidelines for the collection, handling and processing of used cooking oil, along with traceability mechanisms, designated collection centres and incentives for biodiesel manufacturers.
Rai responded positively to the proposals and indicated that the recommendations would be examined for coordinated action involving the relevant ministries and state-level agencies.
KSBDB managing director Shivashankar L was also present at the meeting.
