Knacker

"A Dead Horse on a Knacker's Cart", drawing by Thomas Rowlandson (1757–1827).
A group of dead pigs awaiting pickup by a local knackery, dumped at the edge of a farm site in Scotland; pig farmers in particular prefer the knackery truck not to come close to where live pigs are kept as this is a way that disease can be spread.
Smoke discharging from incinerators at Douglasbrae Knackery, Scotland. The business deals with the disposal of animal carcasses from all over the north-east of Scotland.

A knacker (/ˈnækər/), knackerman or knacker man is a person who removes and clears animal carcasses (dead, dying, injured) from private farms or public highways and renders the collected carcasses into by-products such as fats, tallow (yellow grease), glue, gelatin, bone meal, bone char, sal ammoniac,[1] soap, bleach and animal feed. A knacker's yard or a knackery is different from a slaughterhouse or abattoir, where animals are slaughtered for human consumption. Since the Middle Ages, the occupation of "knacker man" was frequently considered a disreputable occupation. Knackers were often also commissioned by the courts as public executioners.[2]
