### substance | waste:

Industrial waste
* Most industrial waste contains organic pollutants
* Some industrial waste consists of liquids
  - contains chlorine
* can poison the organisms used in sewer plants to remove organic wastes.
* consists of both organic and inorganic substances.
* includes the former special waste and some additional wastes.
* is also a significant polluter - giving rise to contamination with heavy metals
  - another form of pollution soiling the beaches
  - everywhere in North Korea
  - separated from residential waste
* pollute the environment by releasing potentially hazardous compounds.
* refer to wastewater from manufacturing plants.

Infectious waste
* Most infectious waste contains materials
  - radioactive materials
* can be a threat to human health and the environment.
* subset of medical waste capable of causing an infectious disease.

### substance | waste:

Liquid waste
* Most liquid waste contains materials
  - products
  - radioactive materials
* enters the cloaca for expulsion through the urinary bladder.
* includes liquid scintillation vials and bulk liquids.
* is aerated by a large blower as it flows through the tanks
  - dumped into the sewer systems
  - emptied into space
  - gathered in a system of tubules in a flatworm's body
  - piped into lagoons
  - removed from the body through the kidneys
  - turned into a odorless gel instantly on contact
* passes through the blood and the urinary system.
* poses a negligible risk when disposed of by land spread.
* rises to the top of the lagoons, emitting ammonia and methane into the air.

Livestock waste
* account for about a quarter of the agricultural sources.
* are a potential source of groundwater contamination.
* contains ammonia and high levels of organic matter
  - many microorganisms such as bacteria, viruses, and protozoa
* contiminate stream waters with fecal bacteria and disease causing organisms.
* good soil amendment and fertilizer.
* pollutes wetlands with too much organic material.

Medical waste
* includes biohazardous waste capable of causing disease only in humans.
* is also very likely to undergo more than one process
  - incinerated or autoclaved
  - located in beachs
* is the major environmental issue facing hospitals today
  - third-leading cause of emissions from combustion sources
  - waste generated by the medical and veterinary professions

Metabolic waste
* Most metabolic waste includes water.
* Some metabolic waste is produced by animals
  - embryos
* consists of substances.
* diffuse out directly at the body surface.

### substance | waste:

Mixed waste
* are hazardous wastes that are also radioactive
  - low-level radioactive wastes that also contain dangerous chemicals
  - radioactive wastes that are also considered hazardous
* combine chemical and radioactive wastes.
* contain radioactive and hazardous components.
* contains radioactive and chemically hazardous components.
* is actually a combination of hazardous and radioactive trash
  - another category that is both time consuming and costly for disposal
  - both radioactive and chemically hazardous
  - hazardous waste that is also radioactive
  - radioactive waste with a hazardous component or vice versa
* is waste that contains a hazardous waste component and a radioactive material component
  - both radioactive components and other hazardous components
  - includes both radioactive and hazardous components
  - is both hazardous and radioactive

Muck
* have no combat system and are generally considered social hangouts.
* is dejection
