Why do certain oil's need to be recycled separately?
 

For example - the used cooking oil recycle bin outside most restaurant's clearly state's that the only thing to be put in there is used cooking oil. So why is it that we need to separate car oil and cooking oil when recycling?

Lol is this for real??

On the chance your serious the reason is cooking oil is safe to eat and can be recycled for us to eat again, motor oil is not recommended for frying as it tends to kill peoples when you do that.

:popcorn:


Edit: and if you want more details you can always try google??

In addition, used cooking oil can be used for bio-fuel; used motor oil can be used in oil burners to produce heat. Not so much the other way around.

Just a little anecdote: There is a recycling center up in the hills near my parents house to which I used to take used motor oil to dump. They had a sign that clearly stated, "motor oil only." So, to ensure that no contaminants, such as coolant, was in the customers' oil, the "tech" there would dip a paper clip in the oil and light it with a lighter. He would then stare at the flame intently, looking for something, and then declare it okay or not okay to pour into their tanks. My oil was never rejected, even when I had gear oil mixed in, so I don't know what that test accomplished or if it was really nothing more than a scare tactic by the recycling facility... :lol:

By your reasoning, I can use some PAM cooking spray in my engine for lubrication purposes.

Yes I was actually serious. Have you ever seen industrial sized recycling bins for cooking oil before? That stuff looks un-salvagable and looks worse then car oil. That is what got me thinking - if this stuff looks like worse than car oil, why cant you dump in car oil as well? But as other users have mentioned, you can aparently use it for bio fuel as well. But trust me man, if you ever seen an industrial sized recycling bin for cooking oil, you would and could not possibly see how that stuff is recyclable.

Haha I know exactly what your talking about, I used to manage a DQ and we had one of those. But I can see where you're coming from as that stuff is nasty!! I never really thought about how they recycled it though

To OP cooking oil is made from plants and motor/gear oil is from petroleum(or whatever synthetic is). Despite them sharing the name "oil" they are very different chemically and used very differently

Well - If petroleum comes from "Dinosaurs" then isnt it technically "animal oil" like whale oil and we should be able to eat it?

Frankly I dont believe that all Petroleum content comes from Dinosaurs or "plant/animal matter" anyway.

Im pretty sure science proved that's where it came from... But while you have a valid point that it came from animals, it's also aged millions of years and been subject to extreme pressure and heat. While they may have once been similar, they are very much not so now

Ok, so if Earth's Hydrocarbons came from "dinosaurs", then where do you propose that the oceans of Methane & Ethane came from that cover the surface of Titan the moon of Saturn?
Did those hydrocarbons come from "dinosaurs"?

I am confident that every planetary body in the solar system has hydrocarbons (petroleum) once we look hard enough.

Did Earth's petroleum get contaminated by some biologically active components on Earth? - Sure.
There have not been enough plants & animals alive in Earth's history to explain the vast quantities of the stuff we have found, even if every single living cell had been converted to petroleum.

Petroleum and hydrocarbons were present on Earth FIRST, then came the life.
Not the other way around.

I'm not sure you comprehend how many plants have been alive in earths history. And while the chemical components to make oil may exist elsewhere and existed here prelife, that doesn't mean it didn't require the plant and animal material to make it. However I'm quite sure no one knows for sure. You've made a valid point but neither of us can prove either way

That's mostly because car engines are not full of burnt food scraps.

When you have something "consistent" as motor oil, even used motor oil looks semi-decent (aside from the dark color). Cooking oil is usually not filtered by restaurants and is full of whatever was cooked in it along with the grease and fats from food processing.

Have you ever cooked bacon then let the fat cool on the pan? Imagine that x 10000.

Yep, he must have been an old time chemist. After a while, one can get good at it ..... ;)

Quote:

"Flame photometers have a wide variety of applications and are used in clinical, laboratory and environmental settings. Sample purity is an important aspect of using a flame photometer. Typically, laboratory workers calibrate flame photometers before beginning the analysis of a chemical sample. To do so, workers use a series of chemicals called “standard solutions,” for which the proper results are already known. By testing these standard solutions, the laboratory worker can make fine adjustments to the device to ensure that the test results are valid. Many college chemistry courses educate students in the use of flame photometers.

Humfrz is Heisenberg.

Than ought to send most people to google ....... ;)


humfrz

How much of the stuff have we found, vs how much biomass has there been?

Curious about where you're getting the numbers.

:D

Are you yanking our chain to see if we are pay-en attention, or are you being @justatroll .. ??


humfrz

Just go ahead and answer the question:
If the liquid hydrocarbons on Earth all originated in Plant/animal matter, then where did the oceans of ethane & methane on Titan come from?

Well, now @justatroll .......... the reported evidence that ethane and methane exist on Titan has been documented fer sure.

How did it get there? I subscribe to the theory that it's is a product of the chemical processing of primordial solar nebula material. I doubt it had a biological origin.

However, here on earth, I buy into the "biogenic theory" (organic origin) for most petroleum.

Now, if you wish to go with the "abiogenic theory" (inorganic origin) of petroleum here on earth …. good luck finding enough to lubricate the engine of your car.

(where is that MEME that says "science bitch" ..... :D)


humfrz

Next question:
IF organic materials can concentrate in such massive quantities on Titan from "a product of the chemical processing of primordial solar nebula material" then why wouldnt the early Earth concentrate similar materials in even greater quantities?

This is fun ..... :)

Well, for starters, methane has a melting point of about minus 295 degrees F and a boiling point of about minus 258 degrees F. Ethane is down there also.

The average surface temperature of Titan is roughly minus 292 degrees F.

Now Earth has a average surface temperature of about plus 57 degrees F.

So, if a cow farted on Titan, the methane would hit the ground as a liquid (or solid).

If a methane/ethane lake were on Earth ...... the area around it would smell like cow farts.

You see where this is going ....... ;)


What the hell WAS this thread about ??......... :sigh:


humfrz

Methane are farts, right?

Yeah comes from decaying bio matter. But also exists without this occurrence

Ahhh the old interstellar oil debate.
AGAIN!

Well, largely, yes.

If you had ever milked a cow (by hand), on a cold winter morning and had her tail clamped behind your knee (so she wouldn't swish you in the face) and she let out a big fart ..... you would know what methane smells like ...... :(

Sorry ...... I did it again ..... :sigh:


humfrz

Well sir you need a thread about your stories back in the days

Yes, we could call it the "over the hill" thread ...... :thumbup:


humfrz

Hmm this is the second time in a day that request has been made. I guess @soulreapersteve was onto something.

T coat is: the most interesting man in the world

Yep, ya'll stop in for our tech day ....... :D


humfrz

...except the smell ain't the methane part.

Yep true, but the cow adds an oderant, so as you don't stand behind it too long.

Also, the cow add a colorant, so as most people don't step in it .... especially barefoot ......:lol:


humfrz

I've always taken my gear oil to the same place as motor oil. Granted is is just an Autozone so fuck if they know but I did ask the first time. All goes in the same bin

Wait, you can recycle oil now?!? :eyebulge:
Is this why my neigbors give me dirty looks when I do oil changes over the storm drain?

..........:slap:


However, that does keep the mosquitoes down .....:D


humfrz

At least Ultra, Hum, Dhawk and myself used to spray it on the gravel to keep the dust down. Why did we do that you may ask? Because that is what the city/county/state did with it as well. Sorry future generations that was just the way it was.

If you had ever lived or near a gravel road, you would appreciate "keeping the dust down".

Well, it wasn't all bad, as long as the oil wasn't contaminated with PCP.

Besides by keeping the dust down, it kept down the population of mites, that suck the juice out of crops.

In addition, some of it ran into the ditch, creating a thin oil film on the standing ditch water, which kept down the mosquito population ..... thus disease.

Besides that, the oil came from the ground ...... so, we were just returning it..... :D

OK ....... who hid ma meds ......... :cry:
