3) Crossword Puzzle
Directions:Fill in the blanks using the clues given below.
1. The most popular way of getting rid of trash.
2. Reduces the amount of trash in our landfills.
3. A gas produced by landfills.
1. Made by decay.
2. Left after burning.
3. When potentially poisonous substances sink to lower levels in landfills.
4. Where wastes are burned.
5. Can be used to line landfills.
6. Makes up most of our trash.
Ash:A by-product of burning municipal solid waste, or anything else.
Composting:The process of breaking down organic material, such as yard trimmings, by bacteria and fungi to
a humus-like material that can be used as a soil conditioner.
Groundwater Contamination:The pollution of underground water sources; can occur when contaminants
leach into groundwater from landfills.
Hazardous Waste:Any kind of discarded waste that may pose a threat to human health or the environment if
improperly handled; may be solid, liquid or gas.
Incineration:A process used to reduce the volume of solid waste.Extreme heat is applied to combustible and
Landfill:An area of land used to deposit wastes. Most of our garbage is disposed of in landfills. Many of these
areas have reached their capacity and have been closed.
Leaching:The process by which soluble materials, such as pesticides and other contaminants, are dissolved
and washed to a lower level.
Methane:A gas that is formed by the decay of organic material when oxygen is not present. Modern landfills
take steps to capture methane and either burn it or sell it. Methane is a "greenhouse" gas.
Municipal Solid Waste:(MSW) Trash or garbage produced by our homes, institutions and commercial establishments,
including schools, hospitals, restaurants and offices; commonly called “garbage” or “trash.”
Organic:Substances that contain carbon, such as garbage composed of food and yard wastes or other materials
that can be composted
Recyclable:Materials, often disposed of as waste, which can be reprocessed and turned into new materials for
Recycling:The recovery and reuse of useful substances from waste materials; involves the collection of discarded
materials and processing them into new forms which can then be used as raw materials for new products.
Source Reduction:Involves the manufacture and use of products that produce the minimum pollution, use the
minimum packaging, and have a longer life.
Toxic:Poisonous or harmful to humans or other organisms.
Here are some questions with answers that may or may not startle you:
1. How much garbage and trash (municipal solid waste) do Americans produce a year?
Answer: About 200 million tons.
2. Name three ways in which municipalities dispose of their garbage and trash.
Answer: It is buried in landfills, burned in incinerators and decomposed by composting.
3. Of what kind of material is most of our garbage and trash composed?
Answer: Most of our waste (over a third) is composed of paper products.
4. How is recycling helping our landfills?
