Honeywell pioneered the production of sustainable aviation fuel with its UOP Ecofining process, which has been used to produce SAF commercially since 2016. The Ecofining process is a capital efficient solution ideal for producing renewable jet fuel from sustainable feedstocks. For example, renewable jet fuel produced from the Ecofining process using used cooking oil as feed can deliver 60%-80% lifecycle reduction in greenhouse gas emissions compared with aviation fuel from petroleum.
