Polluted dirt is an organic resource that emits polluted oxygen over time if stored at a pressure below 1800g. This can be prevented by submerging the dirt in liquid or storing it under gas pressure of at least 1.8kg/tile. Polluted dirt can be processed through composting, which can then be used as fertiliser. It can also be fed to Pokeshells, who will excrete sand, or used in rockets.

Use polluted dirt to make fertiliser
Polluted dirt can be used to make fertiliser, which can then be used for farming. Here are some methods to achieve this:
Composting
One way to deal with polluted dirt is to compost it and turn it into regular dirt. This can be done by placing the polluted dirt into a compost building, which can be unlocked by researching "Basic Farming". It is important to have wash basins leading up to the compost building to ensure that anyone handling the polluted dirt can wash off any germs.
Mealwood Farm
Another method suggested is to create a mealwood farm and let the produce rot to compost. This method requires some maintenance and may not be as efficient as using fertiliser synthesizers.
Fertiliser Synthesis
Fertiliser synthesis can be used to prolong fertiliser, but it requires the construction of an airlock or jamming the synthesiser inside a gas geyser due to the production of natural gas.
Ethanol Cycle
The ethanol cycle is another way to create dirt. This involves using an ethanol distiller, which can produce a large amount of polluted dirt and can be fully automated. However, this method requires composts to support the process.
Water Sieve
A water sieve can be used to create more dirt from polluted water. Boiling polluted water turns it into steam and dirt, with 1% of the mass becoming dirt. Using a water sieve results in four times as much dirt compared to boiling.
Arbor Trees
Arbor trees can also be used to produce dirt. While they only produce a small amount of dirt, they require less labour than other methods.

Feed it to Pokeshells to get sand
If you have tons of polluted dirt, one option is to feed it to Pokeshells. Pokeshells are non-hostile critters that eat polluted dirt and rot piles and excrete sand. They can live in both air and liquid and can be domesticated. They are found in the Ocean or Tide Pool Biome. Pokeshells have three variants, determined by the liquid they live in, and each has a different drop upon growth and death. All variants consume polluted dirt and produce sand.
Pokeshells can be used to improve the efficiency of sieves early in the game and to produce lime for steel late in the game. The shells they leave behind after molting can be crushed into lime. Pokeshells drop 10 kg of molt when they die (5 kg when a baby dies), which can be turned into lime or wood with a rock crusher. This is the primary renewable source of lime for steel production.
Oakshells are a type of Pokeshell that eats polluted dirt, slime, and rot piles. The main reason for ranching Oakshells is to produce lumber, especially when water for arbor trees is in short supply. They can be used to make ethanol, which can then be used to grow Nosh Sprout. A happy, well-fed adult Oakshell will shed 100 kg of Oakshell Molt per cycle, which can be turned into lumber.
Sanishells are another type of Pokeshell that thrives in water and eliminates germs from any liquid it inhabits. They eat polluted dirt, slime, and rot piles and excrete sand.
Overall, feeding polluted dirt to Pokeshells is a good way to get sand and improve the efficiency of your colony.

Use it to make oxygen
Polluted dirt can be used to make oxygen, but it will be polluted oxygen. Here's how you can do it:
Firstly, you need to create a space to put your polluted dirt. Make sure that the room is properly isolated and has good pressure to contain the polluted oxygen that will be emitted. You can use a bottle emptier to turn the space into a polluted water reservoir, and ensure that the pressure is below 1.8.
Next, you can use a sublimator to turn the polluted dirt into polluted oxygen. This machine will help facilitate the process of converting the dirt into oxygen, though the oxygen produced will be polluted.
Once you have polluted oxygen, you can then begin the process of cleaning it to make it breathable. Sand can be used to clean the oxygen, and pokeshells can be used to make sand from polluted dirt.
It is important to note that this process may not be the most efficient or effective way to generate oxygen, and it may be more practical to explore other methods or approaches to oxygen generation. Additionally, proper safety precautions should be taken when handling polluted materials and oxygen, including the use of wash basins to prevent the spread of germs.

Store it in a storage bin under water to prevent it from emitting polluted oxygen
Polluted dirt is an organic resource and unprocessed biological waste in the space-colony simulation game Oxygen Not Included. If stored at a pressure below 1800g, it emits polluted oxygen over time, even when inside storage bins. This is because the emission rate of polluted oxygen is proportional to the exposed perimeter or the square root of the mass.
To prevent the emission of polluted oxygen, one effective method is to submerge polluted dirt in a liquid. By storing polluted dirt in a storage bin under water, you can stop it from producing polluted oxygen. The water prevents the release of polluted oxygen from the polluted dirt, even if it is just a few kilograms of water in a tile. This technique is especially useful for storing off-gassing solids.
Additionally, you can also prevent the emission of polluted oxygen by storing the polluted dirt under a gas pressure of at least 1.8 kg/tile. This can be achieved by ensuring that the surrounding atmospheric pressure is above this threshold.
There are other ways to deal with polluted dirt as well. Polluted dirt can be converted into dirt inside a compost, which is a simple and low-tech method. It can also be fed to Pokeshells, which will excrete sand and shed shells that can be processed into lime. Another option is to feed it to Sage Hatches, which will excrete solid coal as waste.

Feed it to sage hatches
If you have tons of polluted dirt and don't know what to do with it, one option is to feed it to Sage Hatches.
Sage Hatches are creatures in the space-colony simulation game Oxygen Not Included. They are characterised by their glossy green colour and their diet of organic compounds, including polluted dirt, slime, algae, and normal foodstuffs such as meal lice. They are particularly advantageous for the disposal of surplus polluted dirt.
Sage Hatches are indifferent to bacteria or spoilage, and can consume spoiled, inedible, or over-abundant organics that your duplicants can't use. They can also eat undesirable food like Mealwood and Plant Meat. This makes them a great option for dealing with polluted dirt, as they can convert it into Sage Hatchling eggs and meat, as well as a limited supply of coal. They have the highest conversion rate among all four variants of Hatches, and can convert 100% of consumed mass into coal. This makes them more efficient than Normal or Stone Hatches for coal production. Typically, a herd of seven Sage Hatches will run one generator, which can provide the power for a couple of incubators.
To optimise your use of Sage Hatches, your ranch room should have a separate hatchery adjoining it to provide constant hatch rearing. It is also worth noting that Sage Hatches are a great option if you are attempting the Carnivore or Locovore Achievements, as they can make use of otherwise useless dirt and fertilizer.
