Factorio is a game developed by Wube Software that involves managing a factory on an alien planet. Pollution is a key game mechanic in Factorio, attracting hostile creatures called biters that will attempt to destroy the player's factory. While playing, users have the option to toggle pollution shading on the minimap on and off. This feature was removed in later versions of the game, possibly due to concerns about clutter on the minimap. However, some players have expressed a desire to see pollution on the minimap, and there may be mods available that restore this feature. Additionally, players can view pollution levels for each chunk of the map by enabling the show-pollution-values option.
| Characteristics | Values |
|---|---|
| Pollution on the mini map | Removed in later versions |
| Pollution on the main map | Enabled by a black and red button |
| Viewing pollution on the mini map | Pressing Alt or using the button on the mini map |
| Pollution visualisation | Mods available to visualise pollution |
| Pollution absorption | Trees absorb pollution, with the amount depending on the tree's leaf stage and grayness |
| Negative pollution | Biochamber generates negative pollution |
| Pollution and evolution | Global pollution affects evolution |

What You'll Learn
Toggle pollution view on the mini map
To toggle pollution view on the mini map in Factorio, you can try the following steps:
- Open the options menu and go to Graphics.
- Ensure that the third option, "Show pollution on the minimap when detailed info is on", is turned on.
- During gameplay, you can then toggle detailed info using the Alt key.
- Open the map by pressing 'M' on your keyboard.
- On the map, there should be a red button that allows you to toggle the pollution overlay.
Please note that some players have reported that this feature seems to have been removed from the game as of version 0.15 or 0.16. Players have stated that the option to view pollution on the mini map was removed when filters were added to the main map. The mini map would be solid red for players producing a lot of pollution, making it unreadable.
If you are unable to view pollution on the mini map using the steps above, you may need to update your game to the latest version or search for mods that can enable this feature.

Pollution on the main map
To view pollution on the main map in Factorio, players can utilise the pollution overlay feature. This feature can be toggled on or off in the game settings. By enabling the pollution overlay, players will be able to visualise the pollution levels across the map.
It is worth noting that some players have reported difficulties in seeing pollution on the map, even with the overlay enabled. In such cases, it is recommended to check for installed mods that may interfere with the game's functionality or try pressing the "Alt" key, as suggested by another player.
The pollution overlay provides valuable information about the impact of the player's factory on the environment. It is important to monitor pollution levels as they can attract biters, which are hostile entities in the game. Additionally, water near the source of pollution will turn green, although this is purely a visual effect and can be disabled in the graphics settings.
Players seeking more detailed information about pollution levels can refer to the "show-pollution-values" option in the game. This option allows players to view the numerical pollution level for each chunk on the map, aiding in strategic decisions regarding pollution management.
While the game provides tools to visualise and manage pollution, some players have expressed a desire for improved visibility and colour/contrast options on the map screen. These enhancements could make it easier to grasp the extent and intensity of pollution generated by their factories.

Increasing pollution visibility
In Factorio, pollution is represented as an abstract red cloud. This cloud is visible on the map if the "pollution" setting is on. It is produced by buildings involved in processing items and spreads outwards at a steady rate. The cloud is used to trigger Biter attacks and determine the size of the attacks.
To increase the visibility of pollution in Factorio, you can adjust the graphics settings and map generation settings. Here are some steps you can take:
- Enable the "pollution" setting: Ensure that the "pollution" setting is enabled in the game settings. This will make the pollution cloud visible on the map.
- Adjust graphics settings: Play around with the graphics settings to find the optimal visualization for pollution. This may include increasing the overall brightness or contrast of the game to make the red pollution cloud stand out more.
- Use the map view: Zoom out and use the map view to get a better sense of the pollution levels across a larger area. This can help you see the extent of the pollution cloud and identify areas with high pollution concentrations.
- Enable alternate mode: The pollution cloud is typically visible on the minimap and map when an alternate mode is enabled. This alternate mode can be activated by pressing the "Alt" key. This will give you a different perspective on the pollution levels in the game.
- Use colour and contrast options: Some players have suggested that the map view could benefit from additional colour and contrast options to make pollution more visible. You can provide feedback to the developers or look for community-created mods that offer these enhancements.
- Manage pollution levels: While not directly related to visibility, reducing pollution levels can help you manage its impact on the game. This includes strategies such as clearing biter bases within the pollution cloud and implementing methods to reduce pollution, such as using biochambers, which generate negative pollution.
By following these steps, you can increase the visibility of pollution in Factorio and gain a better understanding of its impact on the gameplay and environment.

Pollution affecting evolution
In Factorio, pollution is represented as a red cloud on the map, produced by buildings involved in processing items. It spreads steadily outwards and attracts biters, who will attempt to destroy the pollution source. While the pollution cloud does not directly increase the evolution factor, it does so indirectly by triggering biter attacks.
The evolution factor is influenced by global pollution, time, and the number of biter nests destroyed. As pollution spreads, it is absorbed by biter nests, increasing the evolution factor. This positive feedback loop results in more nests, which spawn more biters, leading to higher evolution rates.
Players can modify the pollution factor using console commands, increasing or decreasing its value. However, this only affects mobile units, as spawners are not killed by these changes. The pollution cloud's visibility can be adjusted through map generation settings or disabled entirely, but it is no longer visible on the minimap, likely due to clutter concerns.
Pollution's impact on evolution presents a strategic challenge for players. While containing pollution may reduce the frequency of biter attacks, the evolution factor will continue to rise, leading to more advanced enemies over time. Players must carefully manage their pollution output and decide whether to confront or avoid biters as the game progresses.

Absorbing pollution
In Factorio, pollution is a serious concern as it attracts biters that will try to destroy the source of pollution. While it is difficult to completely avoid pollution, there are several ways to reduce and absorb it.
Trees
Trees absorb a significant amount of pollution. However, they degrade over time and eventually become stumps, losing their ability to absorb pollution. Dead trees absorb less pollution, which can lead to higher pollution levels and more dead trees. Therefore, it is recommended to build near forests to take advantage of the pollution-absorbing properties of trees. Additionally, trees near highly polluting items can help reduce the pollution cloud that escapes your base, but only until the trees die.
Grass
Grass can also absorb pollution, helping to restore the environment.
Water
Water near pollution sources will turn green, indicating the presence of pollution. While this effect is only visual and can be turned off in the graphics settings, water bodies can still absorb pollution.
Spawners
Biter spawners absorb pollution, which they use to send biters to attack the source of pollution. Captive biter spawners absorb one pollution per minute, while wild spawners follow the same rules as trees for pollution absorption.
Biochamber
The biochamber generates negative pollution, effectively removing pollution from the environment. Productivity modules can boost the amount of negative pollution generated by the biochamber.
Modules
Efficiency modules can significantly reduce pollution. For example, using three efficiency modules in electric mining drills and oil rigs can reduce pollution by 80%. Similarly, using efficiency modules in nuclear mines, oil rigs, and uranium mines can help reduce pollution in the chain. However, it is important to note that productivity modules can increase pollution while providing free products without inputs.
Solar Power
Solar power generates no pollution except for the pollution created during the fabrication of panels and accumulators. While solar power can help reduce pollution, it requires a significant amount of space.
Electric Furnaces
Switching to electric furnaces supplied with clean energy can reduce pollution by up to 75% compared to traditional furnaces.
