For those who were annoyed by the inconsistent units in the story:
"International Tanker Owners Pollution Federation reporting about 7000 tonnes of crude oil spilling from tankers into oceans in 2017 alone."
".. explosion on the Deepwater Horizon offshore drilling rig on 20 April 2010 and subsequent release of approximately 4.9 million barrels of crude oil into the Gulf of Mexico."
Sometimes I wonder how numbers are regarded in journalism. From the outside it looks as if there was some cult around reproducing the exact string that the source uttered, but with no understanding.
For example, an article might say someone travelled 1243 miles — very precise and authoritative journalism there. Of course, they were actually told they travelled 2000 km, clearly an approximation.
In France, I have noticed that journalists often say they were very weak in mathematics. Probably there is some kind of education effect that drives smart people weak in mathematics toward journalism. People opinion is very much influenced by journalists and I wonder if this selection bias is the cause of the bad image of mathematics (difficult, disconnected from the real world, ...).
Hopefully the Chinese gutter-oil industry[1] will start selling to this purpose, instead of as cooking oil!
[1] https://en.wikipedia.org/wiki/Gutter_oil - while recycling oil from deep fryers might not sound awful, some gutter oil is literally taken from the gutter - sewage is being recycled and sold as cooking oil in parts of China!
Remember that manure has been used as fertiliser for basically as long as humans have existed, so waste being recycled is not a new nor unusual phenomenon.
From the article, at first it looks like the recyclers have done a pretty good job...
The illegal oil shows no difference in appearance and indicators after refining and purification because the law breakers are skillful at coping with the established standards
...but then...
Gutter oil has been shown to be quite toxic, and can cause diarrhea and abdominal pain.
...makes me think the standards and testing processes need to be changed.
Using manure as fertilizer is very different, in the sense that anything grown in fertilizer can be washed before eating. We don't generally wash things between cooking them in oil and consuming them.

According to this site (https://www.reference.com/science/much-barrel-oil-weigh-b29e...) "In order to get a metric tonne of oil, one would need about 7.33 barrels of oil."
7000 tonnes ~ 51,310 barrels
4.9 million barrels ~ 668,485 tonnes

But we don't use human manure for growing food for very good reasons--it tends to transmit diseases.
