Determine whether the description applies to landfills, incinerators, or both

- generate ash

- can generate energy

- emits toxins through combustion

- drains liquids into the ground

- releases greenhouse gases

- requires a substantial amount of land

1. can generate energy - Both, In landfills methane gas is produced which is used to generate electricity, like wise heat energy produced in incinerator is also used for producing energy

2. emits toxins through combustion - Incinerators produce dioxins which is a dangerous chemical

3. drains liquids into the ground - Land fill, leachate is a common issue with all landfill site.

4. releases greenhouse gases - Both, methane and other carbon gases are produced in both landfill and incinerators

5. requires a substantial amount of land - land fill site, needs a large land to dump the city waste

6. generate ash - Incenerator only
