For a long time, it was believed that paper is a relatively safe and environmentally friendly waste product, degrading quickly in landfills. Rathje showed, however, that paper is typically a bad degrader: newspapers dumped in landfills as much as over half a century ago, turn up again as fresh and as readable as the day they were issued.

Weather is a common agitator and cause of garbage landslides. [3] Mounds may collapse if they become heavier from rain and disturbances like strong storms can both trigger sliding and start fires if lightning ignites combustible gases from the landfill. Weather may also induce soil erosion, making landfills more vulnerable to sliding events. [4]
The Kin-Buc Landfill is a 220-acre (0.89 km 2) Superfund site located in Edison, New Jersey where 70 million US gallons (260,000 m 3) of liquid toxic waste and 1 million tons of solid waste were dumped. It was active from the late 1940s to 1976.
The act established a framework for states to better control solid waste disposal and set minimum safety requirements for landfills. [4] In 1976 Congress determined that the provisions of SWDA were insufficient to properly manage the nation's waste and enacted the Resource Conservation and Recovery Act (RCRA).
Landfills are the third-largest source of methane in the US. [ 17 ] Because of the significant negative effects of these gases, regulatory regimes have been set up to monitor landfill gas , reduce the amount of biodegradable content in municipal waste , and to create landfill gas utilization strategies, which include gas flaring or capture for ...
Demolition debris can be disposed of in either Construction and Demolition Debris landfills or municipal solid waste landfills. [4] Alternatively, debris may also be sorted and recycled. Sorting may happen as deconstruction on the demolition site, off-site at a sorting location, or at a Construction and Demolition recycling center. [ 4 ]
Landfill bans make it illegal to dispose of certain items in a landfill. Most often these items include yard waste, oil, and recyclables easily collected in curbside recycling programs. States with landfill bans of recyclables include Wisconsin, California, Minnesota, Michigan, [4] and North Carolina. [5] Other states focus on recycling goals.
In science, third grade students are taught basic physics and chemistry. Weather and climate are also sometimes taught. The concept of atoms and molecules are common, the states of matter, and energy, along with basic chemical elements such as oxygen, hydrogen, gold, zinc, and iron. Nutrition is also sometimes taught in third grade along with ...
