Pollution of the Realms

"Pollution of the Realms" is a mod that introduces blocks of carbon and sulfur emissions from the combustion of various fuels.

These blocks are created around fuel burning sources, rise into the air and accumulate in the clouds. If unchecked, they will affect plants, animals and players in several ways (see "Negative effects" below).


This mod introduces the problem of environmental pollution and encourages modpack makers and players to seek various paths to mitigate the consequences. There are methods provided within the mod itself to do this, but the intent in designing the mod was to encourage flexible solutions when combined with other mods.


Requires ForgeEndertech library.

For best results, use with Advanced Chimneys.

..more about harmful effects



To prevent harmful emissions from entering the atmosphere or greenhouse, place filters on top or in the middle of the chimney pipe.

Each filter can protect against one pollutant and requires filling with filter material, as well as cleaning from byproducts to operate. You can fully automate this process with the help of hoppers.

Each filter also generates a descending redstone signal from 15 (when empty) to 0 (when full). This can be used to control the connected pumps or to activate an alarm, when the filter is full.


Cleaning and Protection

You can clean up the pollution with a special tool - the vacuum tube.

There's three types of vacuum tubes: iron, golden and diamond, that perform better as one would expect.


Note that emissions can't be stored in the inventory (you wouldn't want to get all your stuff smoky and gunky, would you?), so a vacuum bag will be required, with similar capacity upgrades per material.

  • Put on the bag and take the tube in your hand.
  • Aim at the pollution blocks, and hold the right mouse button to vacuum-clean. 

Crafted vacuum bags are equipped with a sulfur filter that can be refreshed on an anvil using wool (2 pieces). Additional filters for carbon or dust can be installed using leaves or paper (2 pieces).


As pollution levels increase, harmful effects will grow as well. To protect yourself, you may need to craft a respirator (each type has a different durability).

Crafted respirators are equipped with carbon and sulfur filters. Dust filter can be installed on an anvil using paper.

Note that a vacuum bag or respirator picked from the creative inventory provides no filters, so you have to install them manually. The same goes for respirators from compatible mods.


You may also need an Aerometer to check the pollution level of the chunk you are in.


Confined spaces

Special care should be taken if you place the source of emissions within a confined space, as this can lead to suffocation or even an explosion.

To prevent fatal consequences make sure of providing a good ventilation, using chimneys, vents and pumps.


Every pump could maintain 4 independent ventilation lines up to 16 blocks in length each (connected from the side) and one chimney pipe (connected to the top).

As a last resort, you could push emission blocks with your hand (more efficiently, holding some item) towards the way out.



Despite the fact that carbon emissions are poisonous for animals and players, they are vital for plants, as they absorb carbon during photosynthesis to take energy for growth.

You can benefit from that by planting crops in areas contaminated with carbon, or by building greenhouses and pumping carbon into them.



To prevent spread of emissions around the furnace, you can place chimneys next to it.

You may need to place additional chimney pipes if your furnace generates too much emissions.

If the chimney is covered by solid block and emissions have no way to go, they will accumulate and subsequently explode.
