Electric crematorium

An electric crematorium is a Production appliance used to destroy corpses as well as unwanted apparel, weapons, or drugs. Despite the specificity in the name, there is no other form of crematorium.

Acquisition

Electric crematoria can be constructed once Electricity is researched. They require 150 Stuff (Stony), 20 Steel, 2 Components, 4,500 ticks (1.25 mins) of work and a Construction skill of 4.

Summary

Crematoria can be used to destroy corpses, apparel, weapons, or drugs by creating bills. The building itself uses 250 W of power, has -10 beauty, and a cleanliness value of -20.

Crematoria produce heats while executing bills at a rate of 12 heat per second,^{[Exact mechanic unclear]}, over half the rate of a campfire and with no maximum temperature. No heat is produced when idle, even if powered on.

It outputs light in a 6 tile radius while it is powered on, with the nearest 3.442 tiles being above 50% light level and considered lit. As the crematorium can only be used while it is powered, and it emits light when powered, this means there is no need for additional light sources to prevent work speed penalties to the operator. The light emitted by the crematorium itself is sufficient.

If the electric crematorium left is out in the rain, a short circuit can start a fire.

Bills

Bills are worked by haulers. All cremation times are scaled only by the General Labor Speed of the hauler performing the bill. In all cases, the item is completely destroyed leaving nothing behind.

Corpses require 180 ticks (3 secs) work to cremate and are cremated together with all of their equipped gear. By default, animal corpses will be filtered out. Mechanoid corpses cannot be burned.
Apparel requires 60 ticks (1 sec) work to burn, regardless of the item or material. Shield belts and smokepop packs cannot be burned (though firefoam pop packs can).
Weapons require 60 ticks (1 sec) work to burn, regardless of the item or material. Only flammable melee weapons, and ranged weapons made from wood (pila, short bow / recurve bow / greatbow / flamebow), can be burned.
Drugs require 60 ticks (1 sec) work to burn, but burns in entire stacks.

Analysis

For an analysis of butchering vs disposal of human corpse, see Human resources.

Crematoria are work intensive compared to other methods of disposing of unwanted objects, and this typically leads them to be neglected. However they do possess some advantages that can be relevant.

Molotov cocktails can dispose items with an open fire; one throw is enough to burn many objects. A safe burn area is required, such as a stone floored and walled room, though this can be cheaper than 1 crematorium. A stockpile zone can be configured to load the corpses, but the player needs to ignite it every time. Also note that the entrance must be forbidden or the Home Zone area removed to ensure no firefighters attempts to put out the cremating fire within.

However, unlike molotovs, electric crematoria don't require Machining to be researched to be be constructed, can be fully automated with bills, and do not involve open fire. In addition, many rotten corpses in a confined space can cause rot stink. This allows the player to be completely hands-off once the process is set up, which can be a significant advantage in some playstyles or colonies.

Finally, unwanted objects can instead be loaded onto transport pods, and launched to other faction's settlements, for a modest relationship gain. Using transport pods solely to dispose of weapons is costly for little gain. You can mitigate this by shipping unwanted gear with other items you would've sent as gifts, anyway (like flake or sculptures). As corpses are heavy, this method is impractical for them.
