Japanese<\/a> homemaker Maki Watanabe carefully \u2060pours into a plastic bottle the oil she used to cook her \u2060deep-fried aubergines, doing her part in her Tokyo kitchen for a national effort to ramp up production of eco-friendly jet fuel.<\/p>\n

\u201cIt would take a tremendous amount to make an aircraft fly, so I hope we can collect more,\u201d said Watanabe, whose penchant for cooking allows her to donate about 40 litres (10 gallons) a year.<\/p>\n

Her contribution is pooled at a nearby supermarket that is among roughly 300 participants in a public-private project dubbed \u201cFry to Fly\u201d, as the Iran war<\/a> squeezes energy supply and raises costs for \u200cthe resource-poor country.<\/p>\n

Japan is looking to consumers like Watanabe with more urgency than ever as it scrambles to reach a goal of procuring a tenth of airline fuel from sustainable sources by 2030.<\/p>\n

The world\u2019s fourth-biggest economy estimates it needs about 1.7 million kilolitres in 2030, and hopes to gain as much as it can domestically through used cooking oil, a relatively cheap feedstock for sustainable aviation fuel (SAF).<\/p>\n

But scarce feedstock and lack of infrastructure have limited domestic output of SAF to just 30,000 kilolitres now, or 0.3 per cent of total jet fuel use.<\/p>\n","protected":false},"excerpt":{"rendered":"Japanese homemaker Maki Watanabe carefully \u2060pours into a plastic bottle the oil she used to cook her \u2060deep-fried…\n","protected":false},"author":2,"featured_media":36322,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[6366,17017,16620,5046,20838,8,2220,27109,27111,33,27113,27112,27110,4180,52],"class_list":["post-36321","post","type-post","status-publish","format-standard","has-post-thumbnail","category-japan","tag-ana","tag-cosmo-energy","tag-eneos","tag-fujifilm","tag-ito-yokado","tag-japan","tag-japan-airlines","tag-jgc","tag-mitsubishi-corporation","tag-nihon","tag-norinchukin-research-institute","tag-revo-international","tag-saffaire-sky-energy","tag-singapore","tag-tokyo"],"_links":{"self":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/posts\/36321","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/comments?post=36321"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/posts\/36321\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/media\/36322"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/media?parent=36321"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/categories?post=36321"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/japan\/wp-json\/wp\/v2\/tags?post=36321"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
