汚染

Update 14 split ground pollution into four separate kinds, each tracked in its own layer of the world and each pointing at a different culprit. This guide lists every block on this server that pollutes the ground, the waste that pollutes only while it sits mixed, and how air pollution feeds back to the ground as acid rain.

The four kinds of ground pollution

• Soil — dumped garbage and biowaste rotting on the ground. The everyday kind: mixed garbage blocks left in the open feed this layer. (1 block)
• Heavy Mineral — mining leftovers: tailings and crushed-rock waste. If this layer is climbing, look at a mine or an ore-processing yard. (2 blocks)
• Chemical — industrial waste from modern industry. The nastiest to host and the strongest argument for sorting and proper storage. (2 blocks)
• Acid Rain — fallout from AIR pollution. It arrives from the sky, not from a block on the ground — the only fix is burning less and scrubbing smokestacks.

Each kind settles into its own world layer, poisons soil fertility under and around it, and clears only when its source is removed. Because every layer is separate, the map tells you WHO to talk to: soil points at dumped garbage, heavy mineral at miners, chemical at industry, acid rain at whatever is smoking.

Blocks that pollute the ground

Ground-polluting blocks

ブロック	Kind	量
化学汚染物質	Chemical	0.1
化学廃棄物	Chemical	0.1
選鉱くず	Heavy Mineral	0.1
鉱泥	Heavy Mineral	0.1
ゴミ	Soil	0.1

Amounts are per placed block, from each block's [PolluteGround] declaration — see a block's own page for its mining and material data.

Waste that pollutes while it sits mixed

A mixed garbage block pollutes for every polluting material still inside it. Sorting a material OUT removes its share on the spot — sorted outputs are clean, and only the residuals keep polluting. That makes the sorter itself a cleanup machine.

Air pollution (and where acid rain comes from)

Burning fuel puts smog into the air. Air pollution warms the climate — and since Update 14 it also falls back down as the Acid Rain ground layer, so a smoky skyline eventually shows up in the dirt.
