Pollution eating technology

[I. M. Notamoose]

Since our civilization has already developed within the past 20 years, titanium oxide coatings and structures that break pollution down, as well as catalytic converters for vehicles to reduce oxides of nitrogen back to oxygen and nitrogen, and carbon monoxide and unburned hydrocarbons to carbon dioxide and water, even including some new ones that do not require rare and expensive elements, then there should be some mods, especially ones using titanium, aluminum, and nickel ores which allow you to produce either a pollution reducing factory or an artificial titanium oxide tree that passively reduces pollution during sunlight hours. (Since the actual structures use sunlight in real life).

Mods already been done.

Bio Industries also has a garden that "eats" pollution as well.

trees! they eat pollution, and turn it into mass. There are several mods for growing trees

In a way, Bob's Modules (with the rest of the pack) is a bit more realistic because building modules requires copper, iron, wood (oil-based synthetic wood and oil-based resin recipes available), lead, tin, silicon, gold, and aluminum. The pollution cleaning effect stops the pollution before it is generated and affects evolution. This is a big advantage over solutions which clean it from the chunk after it is generated.
