Used cooking oil → biodiesel & SAF: 2024 guide #BDF #SAF #Recycling

 Used cooking oil from homes and restaurants can, if collected properly, be reborn as local biodiesel or even aviation SAF. This article, guided by the latest 2024 revision, organizes the essentials of feedstock acceptance—managing acid value, moisture, and impurities—the practical blend approach (generally up to B5), and key points for quality control and storage. The basic rule is to bring oil in PET bottles to municipal or retail collection points—never pour it down the drain. Collected oil fuels community buses and public vehicles as BDF, and, with JAL’s initiative, increasingly circulates as SAF feedstock. On quality, focus on meeting specification items, lot testing, sealed/shaded/low-temperature storage, no open flames, clear labeling, and preventing contamination. Operators should confirm vehicle maker compatibility and safety rules, and inform residents about drop-off sites, schedules, and container requirements—so households, companies, and local governments can turn “waste oil” into a shared resource.

In practice, the most workable approach is to measure a composite “civility score” built from multiple indicators.

  1) Model-based indicators (machine learning) Toxicity/Aggression: Use Jigsaw’s Perspective API to obtain probabilities for “TOXICITY,” “INSULT,” “PROFANITY,” “IDENTITY_ATTACK,” etc. Japanese is supported (see the official language table). Politeness: Stanford’s research established a framework for estimating “politeness” from markers like request forms, hedges, honorifics, etc. It’s English-centric, but the methodology can be adapted to Japanese. The R package politeness is also useful. 2) Lightweight rules for Japanese (highly interpretable) Honorific/hedge rate: Ratios of “です/ます,” “〜でしょうか,” “お手数ですが,” “お願いします,” and the like. Presence of slurs/derogatory terms: A custom NG-word list (including figurative or euphemistic forms). Imperatives/strong assertions: Frequency of “〜しろ,” “〜に決まってる,” heavy use of exclamation marks, ALL-KATAKANA bursts, etc. Consideration/evidence markers: Signs of dialogic and verifiable style such as “根拠：,” “出典：,” “もし〜なら.” 3) ...
