In general, Definition of Waste are remnants of material or waste that are considered not to have a value sourced from the production process, such as from a factory , industry or domestic or household.
There is also another understanding of saying that waste is all material waste or waste originating from a technological process or from natural processes where its appearance has no benefit for the environment and has no economic value.
All types of waste that are sourced and produced by humans, both industrial and household activities must have a negative and negative impact on the environment and for human health, of course.
Where is people's life , that's where various types of waste will appear or be produced. Such as, garbage, black water, and also waste water from various other activities or domestic activities.
In addition to the above explanation regarding the meaning of waste in general, there are also some experts who expressed his opinion regarding the meaning of waste. The following are some expert opinions on the meaning of waste, namely:
1. Karmana (2007)
According to an expert named Karmana, said that waste is garbage or remnants from the program process which can be a raw material for pollution or become pollutants in an environment. All human activities on average produce waste, such as transportation, industrial activities, households, etc.
2. Deden Abdurahman
According to Deden Abdurahman, the definition of waste is waste or waste which is the result of a production process, such as industrial production, transportation or production from households. Which in the presence of waste at a certain time in the environment will reduce the quality of the environment itself.
3. Ir. Hieronymus Busi Santoso
According to an expert named Ir. Hieronymus Busi Santoso, said that waste is a material that is intentionally discarded or wasted from natural processes or from the results of human activities or activities that have not or do not have economic value or can be material that has economic value bad or negative.
4. Daniel A. Okun and George Ponghis
According to experts named Daniel A. Okun and George Ponghis in 1875, said that waste is all liquid waste originating from households, such as dirty water and everything waste industrial origin which is discharged into a system in a liquid sewer line, but rainwater and surface drainage are not included.
5. Hieronymus Budi Santoso
According to an expert named Hieronymus Budi Santoso, argues that waste is all material that is intentionally discarded or indeed wasted originating from the results of human activities or activities and various processes from nature that have no economic value, it can even make people lose.
Impact of Waste
After some of the above explanations regarding the meaning of waste, there are various kinds of impacts that can occur on human health and also in the environment. The following are some of the impacts that can be caused by waste, namely:
1. Impact of Waste on the Environment
Waste in general has a negative or negative impact on the surrounding environment. Not only can it damage the environment and reduce the aesthetic value of the environment, waste can also cause many organisms to die that live in the environment.
For example, liquid waste released by other factories or industries into the river can make the river polluted and contaminated by the toxins contained in the waste. So that it will cause many organisms or living things in the river to die due to poisoning by these wastes, such as fish that live in the river.
Damage that occurs in the river would later be able to disrupt and even damage the ecosystem of living creatures in the river. Besides being able to cause water pollution, waste can also cause air pollution, for example, the unpleasant odor that arises is due to decay of organic or inorganic waste.
Then, combustion of waste, motor vehicle fumes or gases – gases released by industries – industries can also cause air pollution. Which if the poisoned air is inhaled by humans, then it could cause cancer for humans.
2. Impact of Waste on Humans
Besides having a negative impact on the environment, waste also has a negative impact on humans. Although in fact most of the waste on the face of this earth is made and produced by humans themselves, but actually the most able to feel the negative or negative effects of the waste pollution is humans themselves.
There are many impacts that will be felt by humans if the waste has polluted the environment, for example health problems, and so on. The following are some examples of human diseases that can arise due to waste pollution, namely:
- Shortness of breath
- Fungus on the skin
- Nervous disorders
– Types of Waste
Besides waste having a negative or negative impact, waste also has various types. There are 3 types of waste based on their form, source, and compounds. The following are several types of waste, namely:
1. Type of Waste Based on Its Shape
Waste based on its form is further divided into 4 types, namely:
a. Solid Waste
Solid waste or often referred to as waste is waste that has a solid form or form and usually has a dry nature and also usually cannot move or spread by itself without anyone moving it. Solid waste is the easiest and most convenient waste found in the environment around us.
b. Liquid Waste
Liquid waste is waste originating from the remnants of an activity or activity that has a liquid form or form and has been mixed with other discarded materials which dissolve together into the water.
c. Gas Waste
Gas waste is a waste that has a form or form of gas consisting of various kinds of chemical compounds and air as a media use that can spread in a very wide area.
d. Sound waste
Sound waste is waste in the form of sound waves that spread and propagate in the air and can cause interference.
2. Types of Waste Based on the Source
Waste based on the source is further divided into 6 types, namely:
a. Domestic waste
Domestic waste or commonly referred to as household waste, namely waste made and produced from activities or activities in the household or in residential settlements, restaurants, or markets.
b. Industrial waste
Industrial waste is waste originating from industrial activities or activities whose forms and forms depend on what is made and produced from the factory or industry.
c. Agricultural waste
Agricultural waste is waste originating from agricultural activities or activities or plantation activities, etc.
d. Mining waste
Mining waste is waste originating from and produced from mining activities or activities.
e. Tourism waste
Tourism waste is waste originating from and produced from tourism areas.
f. Medical waste
Medical waste is waste originating from medical activities or activities such as hospitals, etc.
3. Types of Waste Based on Their Composition
Waste based on their compounds is further divided into 3 types, namely:
a. Organic waste
Organic waste is waste originating from living things or wastes that have carbon elements in them and have decomposed and decomposed properties which are usually described by microorganisms such as aerobes or anaerobes.
b. Inorganic waste
Inorganic waste is waste that is difficult or not easily decomposed and decomposes naturally which is decomposed by decomposing microorganisms such as aerobes and anaerobes
c. B3 Waste (Hazardous and Toxic Materials)
B3 waste is waste originating from human activities or activities. The waste has chemical compounds and toxic properties that are very dangerous for living things such as humans, animals, or plants.
Here are some examples of waste based on the types , namely:
1. Waste Based on Its Shape
a. Solid Waste, for example glass fragments, used paper, plastic waste, food scraps, etc.
b. Liquid Waste, for example, the remaining fabric dye, feces, laundry water, etc.
c. Gas Waste, for example carbon monoxide (CO), freon, sulfur oxide (SOx), nitrogen oxide (NOx), etc.
d. Sound waste, for example the sound of factory machinery, the sound of motorized vehicles, etc.
2. Types of Waste Based on the Source
a. Domestic waste, for example soap laundry water, food scraps, etc.
b. Industrial waste, for example factory effluents, panric engine fumes, etc.
c. Agricultural waste, for example leaves, straw, small wood, etc.
d. Mining waste, for example metals, rocks, etc.
e. Tourism waste, for example discarded ship oil, vehicle fumes, etc.
f. Medical waste, for example medicinal chemicals, used syringes, etc.
3. Types of Waste Based on their Concentrations
a. Organic waste, for example animal feces, rotten vegetables, food scraps, fruit peels, etc.
b. Inorganic waste, for example glass, plastic, steel, metal, etc.
c. B3 waste (Hazardous and Toxic Materials), for example insect repellents, floor cleaners, air freshener, etc.
Thus our discussion this time regarding the meaning of waste, along with its impacts, types of waste and examples – examples .
