Quite a few people have been suspicious about Adblue, Myself included. So i did some research.
Urea does reduce the nasty emissions from diesel engines, when sprayed into the exhaust.
Urea is a natural product produced in all mammals. But you can’t mass produce it for the commercial market from animals, So you must sorce it from elsewhere.
The alternative is coal.
This is where the problems start. The production of urea from coal produces eight times more CO2, than the benefits it has on diesel engine emmisions. And this dosn’t take into account, Shipping.
So it seems that the world has been conned by EU Buffoons, Again.

Sorry Phil - wrong again:
Urea is a nitrogen-containing chemical product that is produced on a scale of some 100,000,000 tons per year worldwide.
For use in industry, urea is produced from synthetic ammonia and carbon dioxide. Urea can be produced as prills, granules, flakes, pellets, crystals, and solutions.
More than 90% of world production is destined for use as a fertilizer. Urea has the highest nitrogen content of all solid nitrogenous fertilizers in common use (46.7%). Therefore, it has the lowest transportation costs per unit of nitrogen nutrient.
So it actually uses CO2 when it’s made and most of it is used as fertiliser anyway.
It is used to reduce NOX emissions from deisel engines world wide - not just the EU and it also claims to reduce fuel consumption by 3% to 5% giving more CO2 savings.
You’d have to compare the energy (ie Carbon) used to produce AD-blu & compare it to the the energy saved by it use on trucks*, along with the reduced emissions from their engines.
You can apply the same argument with most “green” technology vehicles. Electric cars ? Where does the energy come from to charge them ? Hydrogen car ? Massive amount of energy need to make Hydrogen.
All you can say is that these technologies improve the air quality of congested areas, but until we stop burning coal/oil/gas to make leccy then overall CO2 output wont alter a great deal. Roll on fusion power!
*If Ad-blu is sprayed into the exhaust then I dont see how it effects fuel consumption one way or the other
Trivia:
In the old days “■■■■ Pots” were common around London & other large cities. You would take a leak into them & they were collected & the town’s human urine was shipped up north where it was used in the production of explosives (no synthetic urea in those days).
The Captains of the ships would never like to admit their real cargo, & would try to invent a fake one when asked about it, to which the enquirer when realizing the real cargo would say “Hah! your taking the ■■■■!” which is where the expression comes from.
Saw the best ever on this one a couple of years ago I pulled up in a M S A and a lad put a bottle of **** into a water container added water and put it into the AD BLUE tank curious I walked over and asked the stupid question WHY ■■? New motor ■■? No AD BLUE in shop came the reply it’s the same stuff say’s he AD BLUE is only posh [zb]:!: Checked and seems HE WAS right ■■? NO I DIDN’T FILL MY NEW MERC THE SAME WAY !!! and I don’t advise it either.
Urea is made from CO2 and doesn’t produce it as waste. It is not made from coal.
You conspiracy theorists just annoy me. The world IS round and the Americans DID get to the moon. The Government (so called) can’t even keep their poxy E-mails a secret never mind anything important like how to run a car on water. Spraying urea into the exhaust of a deisel engine is the best way (so far) of reducing NOX pollutants.
Used to take pallecons of urea into Procter and Gamble @ Trafford Park and Thurrock.
They have used it in soap products for years,basically its ■■■■. Now its called “Adblue” and rather overpriced imo.
The Romans used it in places called fulleries, for dying and treating cloth, and i believe its also used in the manafacture of Tweed…its been around a long time
The people who weave Harris Tweed have been using urine goat and human for centuries,it makes the finished garments colour fast,the process is known as waulking the cloth to keep their minds of the stench they would chant or sing.P.S. i AM NOT TAKING anything.

You learn a lot from Adam Hart Davies on Radio 4.
Fascinating fact also never knew that ■■■■ wasnt reduced t [zb]
