Results From Scrapping A Monitor

Although there is still a margin of error, these are the results from scrapping a 17 inch monitor.

.36lbs of Al (@.50lb = $.18)
.66lbs of Flyback Transistor (@.25lb = $.17)
.20lbs of Transformers (@.25lb = $.18)
1.37lbs of Low Grade Circuit Board (@.12lb = $.16)
.72lbs of Copper From The Monitor Yoke (@ 2.75lb = $1.98)
.85lbs of Internal Insulated Copper Wire (.41 if you strip the electrical tape copper wire) (@.90lb = $.77)
2.15lbs of internal shred-price metal (@.10lb = $.22)
.35lbs of external insulated copper cord (@.90lb = $.32)
.05lbs of Monitor End (@1.75lb = $.09)


If you strip the electrical tape copper wire
.16lbs (@.2.95lb = $.47)


Results
Without stripping electrical tape copper wire $4.07
With stripping electrical tape copper wire $4.15

I will post pics if you want

If my math is correct you could get about 87% of the results by leaving the circuit board in tact and not stripping the wire

I am to the point where I open the case, pull the copper yokes and the degaussing wire and call it a day. The space required to store low grade boards is not worth 10 cents per pound. I do pull the boards if they are mid grade but they are not very common. Of course I cut the VGA cable off and the end goes in the gold connector bin.

One thing I have learned is that stripping the degaussing wire is a huge waste of time. The difference in price is 10 or 20 cents per pound so I sell it as is.

I must respectfully disagree about stripping the degaussing cable. If it is copper I always strip it because after you do a few it is real fast and easy and that difference in price adds up fast. Don't forget the little grey copper wire attached to springs.

Thanks for taking the time to itemize everything like that J

Just always remember to ensure it is copper, and not aluminum, even though aluminum will add up, need to be sure what pile to put it into!

I use a 55 gal. barrel and cram it full even if I have to break them to slide down the sides. I should be able to get close to 100 lb's in each one.

Nice breakdown, very accurate.

I strip the degaussing cable. Only the thick stuff, over the thickness of a pencil (not the lead tip, the pencil itsself)

For my lowgrade, it doesnt matter the shape its in. I crush the board after depopulating it. The little bits are then stored in a series of gaylords. Crushed/shredded, they take up a LOT less space.

I tried running degauss through my wire stripper. It does "okay" until it gets to the part where 2 smaller wires are wrapped with 14 miles of tape. Then it jams up.

New plan, whatever that may be.

I did use this to get through the extra tape. Works okay but I don't have a very good grip on it and I will slice myself up one of these days.

Idaho, the part with the 839283 miles of tape. Cut the section out, you can kinda tell where it stops. Just cut that out and turn it in to the yard like that. Then run the rest with yer stripper.

I stripped about 150 of those degaussing cables, using the method i just said. Got about $45 just in the insulated.

That section should be about 4-5 inches long, by the way. Just too make sure you have it all.

You might fabricate a nice hardwood handle for that thing,

Here in Minnesota we have to dispose of the CRT monitor properly and have to pay 25 cents a pound. So if a average weight of a 19 CRT is 20 pounds... That means I have to pay $5.00 for $4.15 worth of scrap. ( I also charge 20.00 per monitor to drop off.) that sounds like a lot bot when you factor in all the "hidden costs", I may make a $1 to $1.50.

I also strip the degaussing cable. As you said, its easy and I love to see the bright copper :). I would just make sure you're not neglecting other more important things to strip it.

Electrical tape is somewhat dense since it is made out of some type of plastic/finberglass. Note the two weights below

You loose about 63% of the weight by stripping. On 20 pounds of degaussing cable

20pounds @ .90 = $18.00

After Stripping

7.4pounds @ $2.95= $21.83

A difference of about $4.00

AND...all of this depends on how YOUR yard grades it. Different formula's for different folks !

AND, it depends if you get ahold of a few that are alum. wire. Like these,

I wish you wouldn't bring that up !! I was turning all mine in as copper cause I did not know that some were Au......UNTIL YOU TOLD ME !!! Now, my conscience won't let me !! AND, after you EDUCATED me I started finding twice as much AU ones....you jinxed me also !!

I will say bravo on this post you did a great job of breaking it down. I learned something from it. I learned that I was right in assuming there is about $5 per tv/crt in value.

Many Thanks for this post.
I love the intricate accounting of every detail. Very nice. The pre and post wire stripping photos are really nice as well.
By the way, I looked through some of your flickr photostream shots and I really liked that blue motherboard from IBM -- very appropriate, a blue board from Big Blue.

I thought you would have seen that in my original post called "breaking down a monitor" back in the summer (I didn't rate a sticky) You can tell if you pick one of them alum. ones up in one hand and a copper one in the other, weighs half as much. and can be about any color. Just clip a few strands to know for sure.

I stripped a early 90's Mitsubishi 29 inch CRT Tv a few days ago & got over 3 Lb's of copper just from the degaussing cable & the yoke.

Thats 1.35Kg of Copper @ NZ$7.30Kg = NZ$9.85,

or US$7.88 from one TV. (plus all the other little bits)

Its weird how the earlyer TVs has Ali degausing cables & the 80's CRT's had big fat Copper cables, anyone know why?
I woulda thought it'd be the other way around, since copper was cheaper way back them.

Good stuff. But I see no one has mentioned about the steel ring that surrounds the picture tube itself. That's another 5-10 lbs for a few seconds worth of time. How I remove it without breaking the glass is by using an angle grinder. In a straight line width-wise of the band, grind it until you see no sparks, then all you do is pry it up with a flathead and peel it off, it's just glued on.

M688, I DID see that...and that is what I meant about jinxing me. After that it seemed like 9 out of 10 were au, and I cursed you every time !!! jk Now I have a big pile of Au ones to strip.

What are you using to shred/crush the boards?

I asked in a thread about using a hammer mill and everyone seemed to think I was nuts for wanting to shred them.

They thought you were nuts because it's more work then needed for low grade.

I just simply hold the board in one hand, and break it into pieces with a pair of needle nose.

Shredding them literally by hand isn't?

Didn't that take forever to get through all those boards?

Right now I'm just stomping them down.

Were they ground up I could double the weight in each gaylord.

Just asking if anyone has any other cost effective options.

Man, sometimes you have to stop worrying about time. Just DO it, quit asking questions.

Not being rude just saying. I'm a rough person, come off as a prick a majority of the time.

Hoss, when breaking up the boards, are you separating all of the surface mount components from the actual boards? I've been taking the heatsinks, transformers and inductors, which i think most people do. Some have said they go after the ICs and transistors as well. Wondering if anyone is salvaging the remaining components and, if so, what this stuff might be worth?

I'm not trying to get a rise out of anyone.

Just sayin', time = money.

My time and the time of my employees.

It's a big factor.

That's why I still have a mountain of TVs sitting at the Health Dept. facility.

The new facility will have the space and we'll have the money to process materials more efficiently with machinery.

I saw you had a large volume as I do.

Just wondered.

I've been doing e-waste recycling for 15 years on a small scale.

Now things are really taking off.

I have a pretty good grasp on what I'm doing.

But, there's always something new to learn.

Questions not asked aren't answered.

If someone here seems to be doing something that can benefit me I'm going to ask.

That's what the forum's for, right?

That's what I'm talking about.

That could actually be useful.

Thanks.

Otto: I do rip all the heatsinks off, as well as any CBM/wire/etc. I take SOME IC chips off. It really just depends. Id say maybe 1 in 100 circuit boards i take an IC chip off.

Primo: Gotcha. I just didnt word myself right. I actually didnt realize you had a good amount of TV's and such. I thought you were still on the pick-up truck load level. My bad. You're right then, time is money. Honestly, if you have a choice, don't take the TV's. Simply arent worth it. I've worked out a perfect schedule for myself. If i dont stick to it exactly, i'm losing money. It's a fine line. Mainly because you have many different levels of breaking it down. You have the "un-wrapping" (taking the back of the tv off) as i call it lol. Then breaking down the board. Breaking down the cone. Then cleaning the board. Cleaning the AL heatsinks, breaking apart certain CBM's that are easily broken down for copper salvage. Finally, stripping the degaussing cable (if it's worth it). So their are many levels.

If you are serious about doing this, MAKE LISTS. Time yourself! You need to get it down to a science, as to how long it takes you to break down each type, and each size. You'll soon get to the point where you can just look at a TV and be like " 25 total minute breakdown, worth $3.11, not worth it". It's all a matter of trial and error. That's what i was trying to get out in my first post. Just came out in a rough way haha. Blame it on my roots.

Question on the flyback transformer thingies - what do you sell them as? My yard wont buy them as copper bearing so i usually throw them as shred.

I've always gotten by putting them in with the other transformers NA
I cut one in half once, just to see what was inside, and it looked like any other transformer would, with the copper windings and such

What Bear said for me to NA. My yard has me just toss them in with rest of the transformers.

I've never cut one open tho..need to add that to my list. I'd like to see the inside of one. LOL.

Sirscrapalot - Winding down from late night break downs.

One things is missing from his list of goodies... CRT TUBE... cost to dispose it...

Minus the goodies he got out of it equal break even.. in My book... and just a FYI,,, You don't lose 63% of the weight by stripping the tape off the degaus wire...

and It does pays to strip the tape off,,,

If You don't have a Wirt Stripper this is what I do.. and I'll do a video on it..

I take the loop cut it in half... one end.. I place it in a vice... then hold the degaus wire out straight and snug.. use a Utility knife.. but I use a Klien Wire stripper knife and With ONe hand tug on the degauss wire, and the other hand slide the knife right on down away from Your body toward the vice... and wa la... it expose the wire.. peel it away and its all clean.. the end in the vice.. come out of the tape easy.. just pull.. the wire out of the tape ...

But I'll put a little video together on it.. its a great way to do it, I usally put about 10 degaus wire in the vice at a time.

Them Flyback transistors why take them off, its mostly plastic and ceramic with a bit of copper in it,, is there someone that actaully buy em>?


I just toss all of these into a gaylord.. and stockpile them.

By the way, not all monitors are alike. Some are encased in pure aluminum and the other writer is correct, you make more by leaving the board intact.

The 67% loss is absolutely incorrect.

I weighed out 10lbs of degaussing cable, took it to work and stripped it then took it straight to the yard afterward. I didn't get a chance to weigh it again after I stripped it but according the their scale I got paid for 10 pounds of copper. Of course they round to the nearest pound, and I was expecting a 10% loss. Either one of our scales could have been a bit off but based on the weights last week I lost less than 5% by stripping. I am still going to use 10% loss as my estimate.

60 something percent is off by a huge margin.

did You get the weight put in for the disposal of the crt what its going to cost you to do it.?

yep that's about the average breakdown I get nice job and I do strip all wires I use a separate machine for deg. wires cause it will build up a lot so I only do reg insulated though my good one even alu. wire I do cause it adds up fast and is money as for boards since the copper and alu is min and more time consuming in the time consuming process of monitors already I am happy to get 6centslb for the board whole it just goes in the tin pile except for the bigger transformers there fast to pop free and save. I usually swim in monitors sitting on about 100right now backed up but get to them when I can that's why I hired my first employee which he is going though the gambit to see if he will continue doing it next he is onto my vcr's and keyboards which should be a few weeks of work lol about 800 vcr's and about 4000keyboards lol
