Argent Energy turning UK’s fatbergs into biodiesel for buses

In the UK, Argent Energy is taking fatbergs collected by the sewer companies and transforming them into biodiesel. Between 24% and 40% of the fatberg ends up as biodiesel after it has been melted down and separated into oil and grease. Currently, every week 30 metric tons of fatburgs from Birmingham are converted into biodiesel by the company but that should increase when the new upgrade allows it to process 300,000 tons of FOG annually. Around 7,000 buses across the country are currently fueled by the FOG-based biodiesel.
