Pollution Reclamation
Adds a standalone air purification and pollution filtering system to Factorio 2.1: a building that actively scrubs ambient pollution from the air, powered by consumable filters that can be cleaned and reused.
Origin
Pollution Reclamation continues an independent line of KrastorioAirPurifier by Tarckmhog, itself a port of the air purifier from Krastorio 2 by raiguard, Krastor, and Linver. KrastorioAirPurifier has no public source repository and its author has no reachable contact channel, so this is a from-scratch reconstruction of the released mod, continued independently under a new name and namespace because the original name is unavailable here. All credit for the original design and graphics belongs to the Krastorio 2 team.
This release (0.1.0) carries no gameplay changes from KrastorioAirPurifier 1.2.2 — it's a straight rename and Factorio 2.1 compatibility update. Full prior history is preserved at the link above.
How it works
Research Air quality monitoring to unlock the Air purifier building and its anti-pollution filter. The purifier consumes electricity (75kW) and a filter to actively remove pollution from the surrounding area — no manual crafting involved, it runs automatically once supplied with filters.
Used filters aren't waste. Feed them back through the Anti-pollution filter cleaning recipe with 100 water and reclaim a working filter, with a chance of recovering coal (and stone, on the advanced tier) as residue.
Research Advanced pollution control for a higher-throughput filter and building tier, roughly 3x the base filtering rate.
Features
- An air purifier building that automatically removes ambient pollution once supplied with filters — no manual operation required.
- A restore recipe that reclaims used filters with water, with a chance of recovering raw materials instead of losing them outright.
- An advanced filter tier for meaningfully higher throughput.
- Space Age support: filter recipes adjust automatically when Space Age is active, and the purifier extends to filtering Gleba's spores.
- Two configurable startup settings to tune filtering efficiency independently for pollution and spores.
Compatibility
Incompatible with Krastorio 2 and air-filtering, since this mod's air purifier is a continuation of the same building — running either alongside it would conflict.
What's next
Pollution Reclamation is under active development. The next phase generalizes captured pollution into a routable fluid with real strategic weight: store it safely, vent it to redirect biter aggression away from your base, or process it into materials and capabilities you can only get by polluting on purpose. Nothing about that is shipped yet — 0.1.0 is the stable foundation it'll build on.
