In Factorio, pollution is represented as an abstract cloud and is produced by buildings involved in processing items. It spreads in all four cardinal directions at a steady rate and can be seen on the map if the pollution setting is turned on. This pollution has consequences for both the world and the player, attracting biters who will attempt to destroy the source of pollution. While pollution settings can be changed or disabled, it is still important for players to manage pollution to avoid frequent attacks from biters. This can be done by reducing pollution through the use of efficiency modules, transitioning to cleaner energy sources, and planting trees to absorb pollution.

Pollution is represented as a red cloud, produced by buildings involved in processing items
In the game 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 determines the size of the attacks.
The pollution cloud is calculated for each chunk and is updated per chunk every 64 ticks (4 ticks more than a game-second). As soon as a chunk has reached 15.0 pollution, it starts spreading in all four cardinal directions at a rate of 2% per 64 ticks. The more the pollution spreads, the more is absorbed. Trees also absorb some pollution, but if the pollution becomes too strong, they will start to die. Dead trees absorb less pollution, which can cause higher pollution levels, resulting in a cycle of more dead trees.
Some of the biggest polluters in the game are steam burner boilers, resource extraction, and raw material processing. The biggest way to reduce pollution is to move away from burner boiler-based power, as these are extremely polluting. Solar power and nuclear power are less polluting alternatives. Electric mining drills are also very power-hungry, so reducing their power will also reduce pollution from power generation.
While it is not possible to completely avoid pollution-induced attacks, reducing pollution can help to keep the cloud smaller and reduce the frequency of attacks.

The cloud triggers Biter attacks, who will try to destroy the pollution source
In Factorio, pollution is represented as an abstract "cloud", with calculations made for each chunk and visible on the minimap and map when an alternate mode is enabled. The pollution cloud is used to trigger Biter attacks and determine the size of the attacks. The cloud is produced by many buildings involved in processing items and spreads outwards at a steady rate.
Biters are attracted to the player's factory by pollution. When biters find themselves in a polluted area, they will attempt to reach the source of the pollution and destroy it. Higher pollution values decrease the time it takes for biters to join the attack force. After a certain amount of pollution is absorbed, the spawner sends one of its biters or spitters to a rendezvous point. Every 1 to 10 minutes, the mustered biters launch an attack. If not all biters have arrived at the rendezvous point by that time, they will wait up to an additional 2 minutes for stragglers.
Pollution has consequences for both the world and the player. It results from production and causes the evolution of enemies. Even if the pollution never makes it to a nest, it will still cause enemies to evolve. The evolution factor is increased by the pollution produced by all the player's machinery at every tick. This means that no matter how hard the player tries to contain the pollution, enemies will still evolve at the same rate. They just won't attack the player as frequently.
To avoid pollution-induced attacks, players can either manage pollution or implement a biter eradication program. While it is not possible to reduce pollution so much as to avoid attacks altogether, reducing pollution helps to keep the cloud smaller. Players can also clear the biter bases in the pollution cloud to prevent attacks.

Pollution spreads in all four directions from its source, generating new chunks if needed
In Factorio, pollution is represented as an abstract "cloud" that is updated per chunk every 64 ticks. It is produced by buildings involved in processing items and spreads in all four cardinal directions at a steady rate of 2% per 64 ticks. This means that if a chunk has a pollution value of 15.0, it will begin to spread to the adjacent chunks. If the pollution cloud reaches a biter nest, they will attack.
The pollution cloud is not just a visual effect, but it has significant consequences for both the world and the player. It is used to trigger biter attacks and determine the size of the attacks. As the pollution spreads, it is gradually absorbed by the surrounding chunks, reducing the overall pollution level. This absorption is slower for larger areas, resulting in a net increase in pollution levels over time.
Additionally, trees absorb some pollution, but if the pollution levels become too high, they will start to die. This, in turn, can lead to higher pollution levels as dead trees absorb less pollution. It is important to note that while reducing pollution can help keep the cloud smaller, the evolution factor of enemies is not determined by the spreading or absorbed pollution but by the total pollution produced by the player's machinery.
To manage pollution, players can focus on reducing pollution from major sources such as steam burner boilers, resource extraction, and raw material processing. Using electric furnaces with clean energy, for example, produces only a quarter of the pollution of traditional methods. Players can also explore alternative power sources like solar or nuclear power, which produce less pollution than burner boiler-based power.

Trees absorb pollution, but too much pollution will kill them, causing higher pollution levels
In Factorio, pollution is a significant concern for players, as it can lead to attacks from biters, which are hostile creatures in the game. While players cannot completely eliminate pollution, as it is a byproduct of production, they can adopt strategies to manage and reduce it. Trees play a crucial role in this regard.
Trees absorb pollution in Factorio, helping to mitigate its spread and negative consequences. However, trees have a limited capacity for absorption, and if exposed to excessive pollution, they will start to die. This creates a vicious cycle, as dead trees absorb less pollution, leading to higher pollution levels and, consequently, more tree deaths. This cycle can have a significant impact on the game environment, and players should be mindful of it when planning their factories and production strategies.
The absorption and reduction of pollution by trees can be beneficial to players in managing pollution-induced attacks by biters. By strategically placing trees near factories and production facilities, players can create a natural buffer that absorbs pollution before it spreads to nearby biter nests. This can help delay or reduce the frequency of attacks, giving players more time to prepare defences or focus on other aspects of the game.
While trees can be an effective pollution mitigation strategy, they are not a permanent solution. Once trees die due to excessive pollution, they do not recover, even if pollution levels subsequently decrease. This highlights the importance of adopting a comprehensive approach to pollution management, including the use of other strategies such as efficiency modules, clean energy sources, and careful factory placement.
Additionally, players should consider the environmental impact of their actions in Factorio. The game provides an interesting perspective on the relationship between human industrial development and the environment, and it encourages players to reflect on the consequences of their actions, including pollution generation and the depletion of natural resources. By considering these factors, players can make more informed decisions and strive for a balance between development and environmental preservation.

Pollution settings can be changed or disabled, but enemies will still evolve at the same rate
In the game Factorio, pollution is represented as an abstract "cloud" and is produced by buildings involved in processing items. It spreads outwards at a steady rate and is visible on the map if the "pollution" setting is turned on. This setting can be changed or disabled entirely, but it is important to note that the evolution factor of enemies is not increased by the spreading or absorbed pollution. Instead, it is determined by the pollution produced by the player's machinery at each tick.
This means that regardless of the player's efforts to contain or reduce pollution, enemies will still evolve at the same rate. However, the frequency of attacks from biters, or "bitters", can be influenced by pollution levels. Higher pollution values decrease the time it takes for biters to join an attack force, and if a pollution cloud reaches a biter nest, they will attack. Therefore, managing pollution can help to keep the cloud smaller and reduce the frequency of attacks.
While it is not possible to avoid enemy evolution completely, players can employ strategies to manage pollution and reduce its impact. This includes focusing on reducing pollution from the biggest sources, such as steam burner boilers, resource extraction, and raw material processing. Electric furnaces supplied with clean energy produce only a quarter of the pollution of traditional furnaces, and efficiency modules can be used to reduce pollution from electric mining drills and oil rigs. Additionally, players can transition to less polluting power sources, such as solar or nuclear power, and manage the number of trees in the environment, as trees absorb large amounts of pollution.
Despite the ability to change or disable pollution settings, the evolution of enemies in Factorio is tied to the machinery used by the player. This mechanic underscores the game's depiction of the environmental impact of human industrial development, where production and research tend towards sprawling development, resource depletion, and the suppression of native inhabitants.
