In the game Eco, pollution is caused by air pollution (CO2) and ground pollution. Sources of pollution include tailings (a byproduct of ore processing), garbage, and sewage (a byproduct of smelting at a blast furnace). Air pollution can lead to rising sea levels, which is permanent and devastating. Ground pollution includes water and can spread through hydrology, seeping into nearby blocks. Players can mitigate air pollution by using pipes to direct it outside, and ground pollution can be reduced by burying tailings. However, some players suggest that pollution does not have long-term effects in the game and that it does not spread beyond its source.

Ground pollution from tailings can be prevented by burying them deep in stone
In the game Eco, players must balance pollution and progression, with the ultimate goal of sustainability. Pollution in the game is caused by either ground pollution or air pollution (CO2). Ground pollution includes water and spreads using the rules of hydrology, seeping into nearby blocks. Air pollution, on the other hand, can lead to rising sea levels, which is a permanent and devastating consequence.
One of the significant sources of pollution in the game is tailings, which are byproducts from ore processing in the mining industry. When valuable minerals are extracted from ore, the remaining rock waste is piled up into tailings, which can reach massive proportions, forming large hills or ponds on the landscape. These tailings can cause environmental problems, including landslides and water pollution.
To prevent ground pollution from tailings, players can employ several strategies:
- Burying Tailings: Players can bury tailings deep underground, preferably in stone or crafted blocks that are sealed to effectively contain the pollution. This strategy is similar to real-life waste management practices, where hazardous waste is often buried in secure containment areas.
- Transporting Tailings: Another option is to transport tailings to a remote location where they won't cause harm. By relocating the tailings, players can allow the original polluted area to recover and heal over time.
- Containment Zones: Players can also build containment areas deep underground to store tailings and prevent them from contaminating water sources.
- Managing Stockpiles: Reducing the tailings stockpile can help mitigate pollution. Players should avoid placing too many tailings in a single area, as this can accelerate the spread of pollution.
- Plant Resistance: Certain trees and plants, such as Ceiba, oaks, and redwoods, absorb more pollution than others. Strategically planting these trees near sources of pollution can help reduce ground pollution from tailings.
By implementing these strategies, players can effectively prevent ground pollution from tailings in Eco. Burying them deep in stone or crafted blocks is a crucial step in containing the pollution and ensuring the game world remains habitable and sustainable.

Air pollution from stoves can be led away with iron pipes
In the Eco game, pollution can be caused by ground pollution or air pollution (CO2). Ground pollution includes water and spreads using the rules of hydrology. Air pollution can turn into ground pollution, which disappears over time. Blast furnaces, combustion generators, and oil refineries are major sources of air pollution.
Air pollution from stoves, specifically gas stoves, is a significant issue that can lead to unsafe levels of indoor air pollution. The combustion of natural gas can release harmful pollutants such as nitrogen oxides (NOx), carbon monoxide (CO), formaldehyde (CH2O or HCHO), and particulate matter (PM2.5). These pollutants can have severe health impacts, including respiratory problems, asthma, dizziness, headaches, fatigue, disorientation, and even death in extreme cases of CO poisoning.
To mitigate air pollution from stoves, proper ventilation is crucial. Range hoods that exhaust outdoors, open windows, and exterior doors can help improve airflow and reduce pollutant levels. Additionally, electric induction stoves are recommended for households with members suffering from respiratory issues or young children.
While gas stoves may be a step towards improving public health and climate change mitigation in certain regions, transitioning to electric cooking is considered a more sustainable long-term solution. Electric stoves produce significantly less PM2.5 and do not emit the same levels of harmful pollutants as gas stoves.
Therefore, to address air pollution from stoves in the Eco game, implementing iron pipes to transport smog and pollutants away from the stoves and living areas can be an effective strategy. By utilizing pipes, similar to the ones introduced in Beta 7.2.x, the spread of air pollution can be controlled and directed away from populated areas, reducing the potential health risks associated with indoor air pollution from stoves.

Air pollution from blast furnaces and oil refineries can be sent through a single waste filter
In the Eco game, air pollution is caused by industrial activities such as manufacturing processes, power plants, refineries, and other facilities releasing harmful substances into the atmosphere. This includes the burning of fossil fuels like coal and oil, as well as metal smelting operations.
One user describes their experience with air pollution from a blast furnace, which turned into ground pollution over time. They noted that the only way to prevent this was to stop using the blast furnace. Additionally, sewage from blast furnaces and oil refineries can be mitigated by sending it through a single waste filter and then pumping it deep into the earth. This method, however, still causes significant ground pollution and has led to discussions about potential improvements in dealing with wastewater.
Another user's experience with a blast furnace, a combustion generator, and an oil refinery running for 72 hours straight resulted in high levels of ground pollution, which they attributed to air pollution washing down. They also mentioned that air pollution always settles where it is created due to the absence of wind currents.
To address industrial air pollution, a collaborative effort is required between governments, industries, researchers, and communities. Emerging technologies like artificial intelligence and machine learning are being utilized to optimize industrial processes and predict pollution events. Additionally, the transition to renewable energy sources, such as solar, wind, and hydroelectric power, can help reduce industrial air pollutants associated with combustion processes.
While the game may not currently reflect all the real-world solutions to air pollution, it is important to note that the game aims to balance pollution and progression while maintaining a certain level of realism.

Air pollution can be minimised by building different outlets with sufficient distance from one another
In the game Eco, pollution can be categorised into two types: Ground Pollution and Air Pollution (CO2). While Ground Pollution is considered to be more basic and dangerous, Air Pollution can also have severe consequences.
Air Pollution in the game is caused by machinery such as the Blast Furnace, Cement Kiln, and Oil Refinery, which can lead to rising CO2 levels and, if left unchecked, can result in rising sea levels. Players have observed that Air Pollution can cause minor Ground Pollution, impacting plant health and leading to temperature changes.
To minimise Air Pollution, players can employ several strategies. One suggestion is to build different outlets, such as factories or refineries, with sufficient distance from one another. This spatial distribution of pollution sources can help dilute the concentration of pollutants in any given area. Additionally, players can utilise waste filters and pipes to transport and sequester pollutants away from populated areas.
Furthermore, players can take advantage of certain trees and plants that absorb pollution. Ceiba (Rainforest), Oaks, and Redwoods are known to absorb the most pollution per tree. By strategically planting these trees near pollution sources, players can create natural buffers that minimise the spread of Air Pollution.
Additionally, players should be mindful of their resource management and hunting practices to maintain a balanced ecosystem. Polluting rivers with mining waste, for example, can poison farms and disrupt the entire ecosystem. Therefore, it is crucial to manage pollution sources proactively to prevent irreversible damage to the in-game environment.

Ground pollution can be caused by untreated sewage from a blast furnace
In the context of the game Eco, ground pollution can be caused by untreated sewage from a blast furnace. Blast furnaces are used for smelting iron ore to produce pig iron, an intermediate material used in the production of commercial iron and steel. They are estimated to have been responsible for over 4% of global greenhouse gas emissions between 1900 and 2015.
In the game, sewage from a blast furnace is a form of ground pollution that can prevent plants and trees from growing in the polluted areas. While some plants are more resistant to pollution than others, high levels of pollution can result in the absence of real plants, such as brilliant green grass.
To address the ground pollution caused by blast furnace sewage, one player suggested pumping the sewage deep into the earth. However, this method still caused significant ground pollution. Another player recommended allowing players to construct tanks to store the wastewater and then process it in a larger wastewater treatment plant or additional filters.
Additionally, it is important to note that air pollution can also contribute to ground pollution in the game. Air pollution from sources such as blast furnaces and cement kilns can wash down and increase ground pollution levels. Therefore, it is crucial to consider both air and ground pollution sources when trying to mitigate the negative impacts on the environment in the Eco game.
