Chapter 2 Waste managementPP

Question 1

Describe four difficulties associated with locating and developing new landfill sites.

Answer 1

Location - There may be objections from local residents due to noise / odour / issues. This will delay planning permission being granted and subsequent award of a permit.
* Suitable transport links are required so that waste can be brought to the site in heavy goods vehicles.

Development- An environmental assessment is required to confirm that the effect of the landfill site on the local environmental is minimal.
* The landfill must include leachate and landfill gas treatment measures to minimise water and air pollution.

Question 2

Name 5 major waste types

Answer 2

Municipal waste
* Commercial and industrial waste.
* Construction, demolition and excavation waste.
* Hazardous waste.
* Agricultural waste.

Question 3

state the options in order from top to bottom in the diagram of The Waste Management Hierarchy.

Answer 3

prevention
reduce
reuse
recycling
energy recovery
disposal

Question 4

Explain the key differences between a ‘bioreactor’ landfill and ‘dry tomb’ landfill.

Answer 4

Bioreactor encourages the decomposition of the waste through the re-injection of leachate and microbe rich water. As a result of the decomposition additional waste can be added.
Dry tomb discourages reactions taking place. Body of waste is sealed and there are high rates of compaction along with minimum flow of rainwater and leachate through the landfill.
