landfill
Let an agent explain what landfills are and how they are designed, operated, regulated and closed, relay environmental and health information from regulators, identify the kind of site meant, and route questions about a specific site to the operator or regulator.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain what landfills are and how they are designed, operated, regulated and closed, relay environmental and health information from regulators, identify the kind of site meant, and route questions about a specific site to the operator or regulator.
A site where waste is disposed of by burial, in modern practice an engineered facility with a lined base, leachate collection, gas capture, daily cover and monitoring, regulated by permits that specify what may be accepted; landfills range from municipal solid waste sites to hazardous waste cells, and older unlined dumps remain sources of contamination.
What it is for: Disposing of waste that is not reused, recycled or recovered.
It can be explain design and operation; explain permits and waste acceptance; relay environmental monitoring and closure rules; distinguish kinds of site.
Distinguishing features
Waste buried under engineered control
Permitted and monitored
Produces leachate and gas
Long aftercare after closure
What it looks like
A large managed area of compacted waste cells covered with soil, with access roads, weighbridge, gas wells and leachate systems.
Physical character
capacity: thousands to tens of millions tonnes - by site
methane content of landfill gas: about 50 percent
How it is recognised
Engineered burial of waste
Permit, liner, leachate and gas systems
Recycling centres, transfer stations and incinerators are other facilities

What the second pass must settle
- Should hazardous waste sites be a separate entry?
- How should regulator registers be linked?
- The registry entry has merged aliases naming sites in Taiwan and scrapyards; should they be split off?
