{{Infobox_Item|name=Machinist Table}}

The '''Machinist Table''' is the core [[Crafting station|Crafting Station]] for the [[Mechanics]] skill. It contains recipes for mid-game items such as the [[Screening Machine]], [[Stamp Mill]], and [[Steam Truck]] components. Many of its crafting recipes require associated machinery to be in the same room, such as the [[Lathe]] or [[Shaper]].{{Description|item=Machinist Table}}

Iron Concentrate

Mack: minor grammatical edits

{{Infobox_Item|name=Iron Concentrate|carried=[[Shovel]]}}

[[Iron Concentrate]] is created by purifying [[Crushed Iron Ore]]. This can be done in one of two ways: either dry or wet purification, each of which can be performed using one of two crafting stations. The crafting stations come with different ratios, labor cost and time. The process to make [[Iron Concentrate]] also gives a by-product of either [[Tailings]] or [[Wet Tailings]], each of which are pollutants. [[Iron Concentrate]] is the last step in the production line before production of an [[Iron Bar]].

The two "Wet" crafting stations that can be used to make [[Iron Concentrate]] are ranked as follows:

'''Level 1:''' [[Rocker Box]]

'''Level 2:''' [[Froth Floatation Cell]]

The two "Dry" crafting stations that can be used to make [[Iron Concentrate]] are ranked as follows:

'''Level 1:''' [[Screening Machine]]

'''Level 2:''' [[Sensor Based Belt Sorter]]

Froth Floatation Cell

Mack: Added short description

{{Infobox_Item|name = Froth Floatation Cell}}

The '''Froth Floatation Cell''' is a crafting station that takes [[Crushed Ore]] and turns it into [[Concentrated Ore Tag|Concentrated Ore.]] It is a more efficient version of the [[Rocker Box]], and it produces [[Wet Tailings]] as a byproduct.

Tailings

Mack: added froth flotation cell changed wording of wet vs dry tailings production minor grammatical edits

{{Infobox_Item|name=Tailings|}}

[[Tailings]] are [[pollution]]-causing blocks that are created when using the [[Screening Machine]], [[Froth Floatation Cell]], or [[Sensor Based Belt Sorter]] to create [[Concentrated Ore Tag|Concentrated Ores]]. Tailings and [[Wet Tailings]] are similar items but are produced by different crafting tables.

Stockpiles and other storage (including [[vehicles]]) containing them will leak pollution into surrounding blocks. Only burying them under a significant amount of material will reduce them from polluting the surface.
== Pollution Spread ==
If they are not stored correctly, they will pollute outward from their location. The pollution will spread in all directions and over time will increase the pollution level of the affected blocks.

Once they are moved or mitigated by burying, polluted blocks will take some time to recover back to normal.

They will continue to pollute at the same rate indefinitely, with no dropoff over time. There is no difference in the pollution emitted by them when stored in a stockpile or when placed outside of a stockpile.
{{See|Pollution}}
== Preventing Pollution ==
There is no way to totally prevent pollution. The amount of pollution caused by tailings can, however, be mitigated by burying them underground.

They must be buried under solid blocks (not rubble, such as [[Stone]], for example). [[Dirt]] is the most economical choice, but almost any block can be used. The hole you bury them in does not need to be lined with any specific block, and can even be open underground as long as there are blocks above them.

Burial is the key to mitigating pollution. The deeper you bury the tailings from the surface block, the less leakage occurs. By 25-30 blocks below the surface, pollution leakage is small.
=== Specifics ===
They pollute ~50% less for every 5 blocks down you bury them. As in at a depth of 5 they will produce 50% of its pollution; at a depth of 10 it will produce 25%, and at 15 it will produce 12.5%. Going on infinitely until it approaches zero pollution, but technically it will always release some amount of pollution. [https://discordapp.com/channels/254025510651297802/254025510651297802/583448585014738957]

The surface/top block is where it begins the depth calculation before reaching the tailings. If you placed a single block 1000 meters in the air above a tailing, it would effectively be buried at a depth of 1000 meters. That's partially why giant towers of tailings end up not polluting as much as you think they will - that and the height differences make pollution spread slower.

=== Storing in vehicles ===
While it is possible to store in vehicles, they will emit pollution as if they were not mitigated at all, even if the vehicles are buried. They must be taken out of the vehicle inventory and buried in Stockpiles or individually on the ground.

Pollution

2021-12-20T12:25:15Z

Mack: Changed "smelting" to "ore processing," added other sources of sewage

[[Pollution]] in [[Eco]] is caused by either [[Pollution#Ground_Pollution|Ground Pollution]] or [[Pollution#Air_Pollution|Air Pollution]] (CO²).

Plants and trees will not grow in polluted areas, but some plants are more resistant to pollution than others.

The sources of pollution and the spread of the pollution can be inspected on the [[Map]] using layers.
== Types of Pollution ==
=== Ground Pollution ===
Ground pollution includes water and spreads using the rules of hydrology, and "seeps" into nearby blocks.

Ground pollution is caused by:
*[[Tailings]] - A byproduct from ore processing.
*[[Garbage]] - Created when a player drops items on the ground.
*[[Sewage]] - A byproduct from Smelting at a [[Blast Furnace]], as well as other machinery. It can be transported through [[Pipe|Pipes]].
''"Currently, pollution reduction for Ground Pollution is based on how many solid blocks are above it, every 5 solid blocks reduces pollution by 50%. For example, with 10 solid blocks above the reduction would be 75%, with 15 it would be 87.5% and so on."'' - Version 0.9.2
==== Ground Pollution Example ====

=== Air Pollution ===
Air pollution spreads through the air, and has the same effects on the fauna and flora as ground pollution, but is quick to dissipate if given time.

Trees absorb CO<sub>2</sub> at the following daily rates:

Birch: -0.075

Cedar: -0.075

Ceiba: -0.15

Fir: -0.075

Joshua: -0.0375

Oak: -0.15

Old Growth Redwood: -0.15

Palm: -0.0375

Redwood: -0.15

Saguaro: -0.0375

Spruce: -0.075

Air pollution is caused by:
*[[Smog]] - Smog is caused by the burning of fuels at [[Crafting#Crafting Tables|Crafting Tables]], or by the use of [[Vehicles]]. It can be transported through [[Pipe|Pipes]].
Prolonged air pollution can lead to sea level rising, which is devastating and is permanent.
==== Air Pollution Example ====
Air Pollution Spread is very aggressive. This is with a [[Blast Furnace]] and [[Cement Kiln]] venting to the same exhaust [[Pipe]] operating for about 45 mins.
