Toxic wastepack

Toxic wastepacks are waste products created by mech-related buildings or the cleanup of polluted tiles.

Acquisition

Pollution pumps and pawns manually cleaning pollution on the ground will generate wastepacks, at a rate of 1 wastepack per 6 polluted tiles. Wastepacks may also be dropped into your colony as part of a quest.

Mechanoid Recharging and Gestation

Toxic wastepacks are produced when friendly mechanoids utilize mech rechargers or large mech rechargers, or whenever a mech gestator or large mech gestator finishes gestating one. The amount of wastepacks produced is proportional to the Bandwidth of the mech recharged or gestated.

Mechanoid Type	Bandwidth	Wastepacks Per Recharge
	1	5
	2	10
	3	15
	4	20
	5	25

Summary

Up to 5 toxic wastepacks can fit into 1 tile, and they do not fit on shelves.

Pollution

When a wastepack is destroyed in any fashion, they will pollute 6 ground tiles of a colony, per wastepack. A full stack of 5 wastepacks pollutes 30 tiles. When burned or damaged, they release tox gas, in addition to the pollution.^{[Detail Needed]} (What about natural walls / walls? Do they polute underneath?).

When dropped in a caravan or unmanned transport pod, they will lower goodwill of a nearby faction by some amount. In addition, factions may drop wastepacks back at you,and hostile factions can start a raid.^{[Mechanics unclear]} Waste dropped this way immediately pollutes the world tile they're dropped on by 0.05% - it takes 2000 wastepacks to fill a hex. Dropping them on a water hex applies an 8x multiplier, meaning 250 wastepacks will fill it.

Dissolution

1 wastepack per stack will dissolve every 8 days, with the following factors:

0.5x if indoors.
2x if in Rain and outdoors, even if roofed.
0x if 0 °C (32 °F) or lower. No decrease for any temperature above freezing point.

This is seperate from the actual deterioration mechanic. Even if temperature is below freezing, a wastepack will slowly lose HP and eventually be destroyed, when left outside and unroofed.

Analysis

Disposal

Most means of destroying wastepacks have some sort of consequence:

Letting it deteroriate naturally. Pollution is localized - wastepacks that deteroriate away from your base won't have an impact, at least for a while. Insectoids may come as wastepacks are destroyed, and acidic smog can happen at high enough pollution levels.
Dumping it. Dumping near a faction base (up to 41 tiles, ?unknown safe distance?) will lower goodwill proportional to distance, wastepacks, and current goodwill. Wastepacks may also be dropped back at you, and if the faction is already hostile, you may start a raid. Dumping within 4 tiles of your colony will increase the chance for acidic smog.
- Caravans take time and food to set up, and have a limited carrying capacity - especially without pack animals or friendly mechanoids.
- Transport pods can dump wastepacks far away. You can choose which faction to anger, or possibly dump it away from anybody. 1 pod, which can store up to 25 wastepacks, costs 50, 1, and variable chemfuel.
- Shuttles store up to 166 wastepacks (1000kg) at a time, and simply transporting waste will not anger the Empire - dumping it has the usual penalties. This costs 1 permit slot, has a cooldown of 40 days, and requires a noble pawn of at least Knight rank. This permit can theoretically support up to 5 bandwidth (although the realistic value is slightly smaller).
Wastepack atomizers have no direct consequences from their use. However, they require a precious nano structuring chip to create, a fair amount of power, and aren't fast. One atomizer can support 2.4 bandwidth of mechanoids - a mechanitor is very likely to have more.
Polux trees, which are another clean form of pollution removal. These trees only grow naturally if there is plenty of pollution already, though seeds can be bought from traders. They clean only 20% as fast as a Wastepack atomizer, and can only clean if there is no artificial buildings in the area, but will erase pollution directly from the ground.
