| 6337337764 | Municipal Solid Waste | MSW. Refuse from households, small businesses, and hospitals. | 0 | |
| 6337337765 | Waste Stream | Flow of solid waste that is recycled, incinerated, placed in a solid waste landfill, or disposed of in another way. | 1 | |
| 6337337766 | Three Rs | Reduce, Reuse, Recycle (from most effective to least effective) | 2 | |
| 6337337767 | Source Reduction | Seeks to reduce waste by reducing in the early stages of design and manufacture the use of materials destined to become MSW. For example: a company decreases the amount of packaging per volume of product. | 3 | |
| 6337337768 | Reuse | Allowing a material to cycle through a system longer by reusing it. | 4 | |
| 6337337769 | Recycling | Process by which materials destined to be MSW are collected, turned back into raw materials to make new objects. | 5 | |
| 6337337770 | Closed Loop Recycling | Recycling of a product into the same product. | 6 | |
| 6337337771 | Compost | Organic matter that has decomposed under controlled conditions to produce an organic rich material that enhances soil structure, cation exchange capacity, and fertility. Waste dumped into tipping area, compostable and noncompostable materials are separated, noncompostable material is removed to landfill, compostable material is aerated and turned 1+ tines for a period of a month to a year, composted material is allowed to cure, finished compost is transported for use. | 7 | |
| 6337337772 | Sanitary Landfills | Ground facilities to hold MSW with as little contamination as possible. Solid waste transported to landfill, waste compacted by a specialized machine, leachate collection system removes water and contaminants and carries them to waste water treatment plant, landfill is capped and covered with soil and then planted with vegetation, methane produced in closed cells is extracted and either burned off or collected for use as fuel. | 8 | |
| 6337337773 | Tipping Fee | Fee for dumping in landfill because of tremendous cost of initial build. | 9 | |
| 6337337774 | Siting | Designating a location for a landfill. | 10 | |
| 6337337775 | NIMBY | Not In My Backyard attitude. People don't want things like landfills to be put where they live. | 11 | |
| 6337337776 | Incineration | Process of burning waste materials to reduce their volume and mas and sometimes to generate electricity and heat. Waste dumped into refuse bunker, crane moves material from bunker to hopper, waste burned in incineration chamber, ash is collected and removed from plant, baghouse filter helps filter clean air before its released through chimney, heat energy can be used to create steam and generate electricity. | 12 | |
| 6337337777 | Ash | Residual nonorganic material that does not combust during incineration. | 13 | |
| 6337337778 | Bottom ash | Residue collected underneath the furnace. Needs to be treated as hazardous waste. | 14 | |
| 6337337779 | Fly Ash | Residue collected beyond the furnace. May contain toxic chemicals such as Cadmium. | 15 | |
| 6337337780 | Waste to Energy | When heat generated by incineration is used rather than released to atmosphere. | 16 | |
| 6337337781 | Superfund | CERCLA. Imposes tax on chemical and petroleum industries. Revenue from the tax is used to fund the cleanup of abandoned and nonoperating hazardous waste sites where there is no responsible party. | 17 | |
| 6337337782 | Brownfields | Contaminated industrial and commercial land that didn't make it into Superfund. Need environmental cleanup before they can be redeveloped or expanded. | 18 | |
| 6337337783 | Life Cycle | Important systems tool that looks at materials used and released throughout entire lifetime of the product. | 19 | |
| 6337337784 | Integrated Waste Management | Employs multiple waste reduction strategies. Changes in packing design, manufacturing practices, in purchasing habits, increased reuse, backyard composting, recovery for recycling, composing. | 20 | |
| 6337337785 | Mass, Density, Volume |  | 21 | |
| 6337337786 | PCB's | (Polychlorinated biphenyls) are synthetic chemicals widely used from the 1930s to the 1970s in industrial products such as heat exchange fluids, paints, plastics, and lubricants | 22 | |
| 6337337787 | Deepwell Injection | liquid waste is pumped into the ground via wells | 23 | |
| 6337337788 | Mining and Agriculture | largest sources of solid waste | 24 | |
| 6337337789 | Open Dump | take up a lot of space and are a risk of spreading harmful chemicals through fires | 25 | |
| 6337337790 | waste | mineral outputs from a system that are not useful or consumed | 26 | |
| 6337337791 | Planned Obselesence | product designed to become waste | 27 | |
| 6337337792 | Perceived Obselence | product seems to be waste | 28 | |
| 6337337793 | Leachate | polluted liquid produced by water passing through buried wastes in a landfill | 29 | |
| 6337337794 | RCRA | Resource Conservation and Recovery Act, 1976, human health protection by limiting hazardous waste | 30 | |
| 6337403698 | 33% | This percentage of MSW could be composted | 31 | |
| 6370087536 | 400 lb less | If a person generates 2000 lbs of waste per year and is able to cut that waste by 20%, how much less waste do they generate? | 32 | |
| 6370103593 | 1 X 10^7 lbs | A typical Illinois resident generates 5.0 lb of waste per day. If there are 20 million people in Illinois, how many pounds of waste are generated? give answer in sci notation | 33 | |
| 6370119496 | 31.25 lb | A pesticide has a half life of 20 years, if 1000 lbs are put into the environment today, how many pounds will be left in 100 years? | 34 | |
| 9300569932 | Love Canal | Famous Superfund site that was caused by the Hooker Chemical Company | 35 | |
| 9300574181 | sanitary landfill | Most MSW generated in the US ends up where? | 36 | |
| 9300577822 | clay as it impedes the flow of leachate into the groundwater | what is the best soil type for siting a landfill? | 37 | |
| 9300581044 | leachate | the liquid collected at the bottom of a landfill is called | 38 | |
