Answer:

Landfills:

1. A landfill site (also known as a tip, dump, rubbish dump, garbage dump or dumping ground and, in archeology as a midden is a site for the disposal of waste materials.
2. Landfill is the oldest and most common form of waste disposal, although the systematic burial of the waste with daily, intermediate and final covers began in 1940s.
3. In the past, refuse was simply left in piles or thrown into pits.
4. Some landfill sites are also used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling.
5. Unless they are stabilized, landfills may experience severe shaking or soil liquefaction of the ground during a large earthquake.

Composting:

1. Composting is a form of waste disposal where organic waste decomposes naturally under oxygen-rich conditions.
2. Although all waste will eventually decompose, only certain waste items are considered compostable and should be added to compost containers.
3. Food waste, such as banana peels, coffee grinds and eggshells, are great items to compost.
4. Adding meat products to compost should be avoided because as it decomposes, it will attract large animals and will smell very badly.
5. In addition to food waste, yard waste, such as grass clippings and leaves, can also be added to compost containers.
6. These items will help increase decomposition and help reduce odor as materials break down.
7. As with household food waste, there are also some types of yard waste that should be avoided.
8. Perennial weeds, which are plants that come back year after year, should not be added to compost because they will grow back and spread.
9. Once these waste items are placed in a pile, the composting process can start.
10. The organic materials are broken down naturally by earthworms, bacteria and other organisms that live in soil.
