Basics

Essentially Strip Mining but of Landfills
Easier with modern landfills, but can be done with old (even informal) ones.
In older ones, it can even be of historic value (like a time capsule of sorts, anthropologists, and archeologits do this with old "mounds" with mainly shells and bones of food, but this is a similar modern form)
Leads to:
- Recovered Recyclable Materials (Metal, Glass, Plastic, Misc)
- Recovered Soil/Clay (cover material)
- Recovered Aggregate Materials
- Sometimes Methane Gas (if captured and not released)
- Typically large Sulfur Compound Gasses, and Mixed Chemical Leachate, which is toxic, but can be processed into useful products
- Refuse Derived Fuel (sort of like biomass, but much more unpredictable)
  - This can in turn be made into Syngas and Slag
Finally the land is returned to it's natural state and/or develped

Challenges

Nastiness of the work site
- Although Dedicated “Work Clothes” / “Junk Clothes” + Boots and a “Wash Out” + swap clothes and boots based Contamination Reduction Zone can help with this
- Also Automation/Mechanization or things like PAPR Helmets with Granulated Activated Carbon cartridges
