Japan is expanding a public-private initiative to collect used cooking oil from households to produce sustainable aviation fuel (SAF).
The program aims to reduce Japan's reliance on imported fossil fuels while addressing global energy-supply pressures. By converting waste oil into jet fuel, the nation seeks to lower the carbon footprint of its aviation sector.
The "Fry to Fly" project currently involves approximately 300 participants [2], including households and supermarkets nationwide. In Tokyo, homemakers such as Maki Watanabe participate by collecting used oil from their kitchens and delivering it to designated collection points.
This effort is part of a broader national strategy to transition the aviation industry toward greener energy sources. The Japanese government has set a specific goal to ensure that 10% of the country's jet fuel comes from sustainable aviation fuel by 2030 [1].
To reach this target, the program relies on a network of supermarkets and residential participants to create a consistent supply of feedstock. The process transforms common kitchen waste into a high-energy fuel capable of powering commercial aircraft, a shift that requires significant public cooperation to scale.
While the project is currently operating with a few hundred participants, the scale of the 2030 goal suggests a need for wider adoption across Japanese cities and rural areas. The initiative represents a shift toward a circular economy where domestic waste is repurposed for critical infrastructure needs.
“Japan aims to have 10% of its jet fuel come from sustainable aviation fuel by 2030.”
This initiative reflects Japan's strategic pivot toward energy security and decarbonization. By leveraging domestic waste streams like cooking oil, the government is attempting to mitigate the volatility of international fuel markets while meeting international climate commitments. The success of the 2030 target depends on the ability to scale this grassroots collection model into a standardized industrial pipeline.
