Isn't "byproduct" the preferred form? --DV 08:16, 1 Sep 2004 (UTC)

I'd have thought so, too, but both OED and Websters use the hyphenated form. Elf | Talk 15:43, 4 Feb 2005 (UTC)

"By-product" is thoroughly outmoded in modern English, so no matter what old dictionaries say, eliminate the hyphen. Common examples: coal byproducts, peanut byproducts, petroleum byproducts, soybean byproducts, byproducts of ore processing. In the latter case, the primary ores for copper & nickel (such as in Ontario) yield byproducts of silver, gold, antimony, selenium, and so forth. The processing of uranium ores yields the byproducts of polonium, radium, protactinium, francium, etc. The reprocessing of nuclear-reactor fuel rods yields more radioisotopes as byproducts that can be easily listed.47.215.180.7 (talk) 03:22, 20 February 2018 (UTC)

Why? Seems to me there's enough material out there to make an article out of this. What's already there is more than a mere definition already. Elf | Talk 02:00, 21 Feb 2005 (UTC)

A by-product is a generic thing; it is the context that it is produced in that renders it a specific meaning. It would be better to provide a definition for the term and place the information that has already been put into the stub into (and I'm not looking up the particular articles) a) mad-cow disease, b) butchering, c) chemical reaction. Not to mention by-products of industrial animal growth for food (massive amounts of nitrogenous waste), the by-product of high-level antibiotic use in such operations (emergence of resistant strains of bacteria), the the initial theory of gravity as a by-product of Newton's being hit upon the head with an apple (I'm not sure what the current thought is on whether the event actually happened or not :) ), the partial collapse of the beef industry as a by-product of a great deal of press about mad cow disease, etc. etc. Such diversity of uses suggests that it should be treated as a word to be defined and then used in articles as is appropriate rather than having an article written about it itself.

Hmmm, I'm reading your thought process sort of backwards and thinking that it might be better as a disambiguation page (which often has a brief definition and then lists of places where detailed uses are defined, described, discussed. Whatchuthink? That would mean someone would have to figure out where the dab links are...  ;-) Elf | Talk 05:21, 21 Feb 2005 (UTC)

That's a tough one. If one went that route then the target pages should likely be redirects with the message Template:R from related word attached; I know that these redirect-message templates aren't working right now, but I'm adding them when needed in anticipation of a fix at some time. For instance, take the animal by-product / mad cow disease relationship. One could refer on the disambiguation page to "animal by-products in the context of mad cow disease" with a link to By-product (CJD) which would be a redirect to Creutzfeldt-Jakob_disease.

Thinking about this some more, a better alternative might be List of uses for the word "by-product" rather than a disambiguation page. This could include the short definition that you suggest for a disambiguation page. Courtland 14:28, 2005 Feb 21 (UTC)</nowiki>

Heat

Does heat also count as a by-product? Artman40 (talk) 18:05, 17 May 2011 (UTC)

It would if it were put to some useful purpose, such as in an electrical co-generation scheme. The use of waste heat from motorcar engines to operate heaters/defrosters in vehicles would be another example. K7L (talk) 13:06, 7 September 2013 (UTC)

I think that you are being completely ridiculous because there is such a thing as COMMON KNOWLEDGE. When the humidity gets high, and the temperature goes down, then we get rain, snow, and sleet. Furthermore, this water falls because of gravity. In the world of legal systems, such things are called "judicial notice", and they do not need to be verified by expert witnesses and evidence every time that they are mentioned.47.215.180.7 (talk) 03:43, 20 February 2018 (UTC)

"Judicial notice is a rule in the law of evidence that allows a fact to be introduced into evidence if the truth of that fact is so notorious or well known, or so authoritatively attested, that it cannot reasonably be doubted."47.215.180.7 (talk) 03:46, 20 February 2018 (UTC)
