What Are The Four Types Of Landfills?

Municipal solid waste, commercial trash, and hazardous garbage are the three types of landfills now in use. Each accepts different forms of garbage and employs different environmental policies. In addition, a new landfill type called green trash is emerging that allows for the controlled removal of organic wastes.

Landfills For Municipal Solid Waste

If you throw it away in a rubbish can, it’s likely to wind up in  municipal solid waste (MSW) landfill. When you think of a landfill, these are usually the first things that come to mind. However, just because they’re the most prevalent doesn’t mean they’re accessible to the general population.

MSW landfills have among of the tightest safety and monitoring rules since they handle a wide range of household waste, from used tissues to a roll-off dumpster full of boxes from a basement cleanout. Location limits, landfill lining, operational practices, groundwater monitoring, and closing techniques are all common examples of these requirements.

So, how exactly do MSW landfills function? It’s all about the layers. The liner, sewerage system, gas collecting system, and the waste itself make up a four-layered system in modern landfills. Each of these levels is continuously monitored to ensure that the landfill is secure for both the environment and the workers.

Landfills For Industrial Waste

If it appears that this landfill was self-explanatory, you are correct. Industrial garbage is disposed of in an industrial waste landfill. While these landfills can accept any form of solid industrial waste, they are most typically utilized for building debris disposal, that is why they are known as C&D landfills. The following items are frequently dumped in industrial landfills:

  • Concrete
  • Lumber
  • Asphalt
  • Gypsum
  • Metal
  • Bricks
  • Components of construction 

Rather than simply storing construction waste in a pit, C&D landfills frequently serve as material recovery stations (also known as MRFs). To do this, the goods brought in are thrown into  pile, then processed by landfill personnel to determine which materials are recyclable and which should be discarded. Local resale stores and firms that specialize in building with salvaged materials accept the reusable items as donations or purchases. In addition, the material recovery facilities may be able to recycle the materials on-site, for as by chipping lumber into mulch.

Landfills For Hazardous Waste 

Hazardous waste landfills were the most tightly controlled and constructed landfills for a variety of reasons. They’re made to contain hazardous waste in a method that essentially precludes the possibility of it being released into the environment. The following are some of the] design requirement  for toxic waste landfills:

  • Liner with two compartments
  • Two-stage system for collecting & eliminating leachate
  • Systems for detecting leaks
  • Controls for run-on, run-off, and wind dispersal
  • Programs to ensure the quality of construction

Toxic waste landfills are frequently audited numerous times a year, in additional to these design criteria, to ensure which the facility is up to code & that the standards are high.

If you’re worried that you’re trying to get rid of a restricted item, rest assured that you’ll have a hard time doing so. Toxic material is not collected curbside &  is only permitted in dumpsters with advance notice – and even then, only on rare occasions.

Landfills For Green Waste

Many communities are beginning to give a place for organic debris to organically degrade, even if these are never officially approved landfills by the EPA. Most traditional landfills & transfer stations are not like welcoming of organic products like fruits, vegetables, and, in particular, yard trash disposal, hence these composting sites are also on the rise. “Some will charge a premium rate for yard waste,” Morris said. This is entirely depending on your local government.”

The Following Are Examples Of Common Kind Of Green Waste:

  • Mulch
  • Weeds
  • Leaves
  • Branches of trees
  • Food waste that is biodegradable
  • Trimmings of grass and flowers

Green trash dumps serve a straightforward purpose: they preserve room in another MSW landfills by keeping a substance out that is supposed to decay organically. Composting landfills, according to a recent EPA study, are reaching that goal. In 2017, 24,420 tones of yard trimming were composted, with 8,650 tones being sent to the landfill, compared to 4,200 tones composted and 25,560 tones sent to the garbage in 1990.

Does smoking pollute the air

It is easily understood how smoke pollution effect the air.

Yes you guessed it right; when a smoker smokes he is inhaling the smoke in & out. The chemical smock that has been created by burning of tobacco is causing the air pollution. You already know that cigarette contains more than 4000 harmful chemical elements which easily cause smoke pollution.

Some harmful elements that pollutes air, carbon monoxide, DDT, maltitor, formaldehyde,tar, methoprene, sulfuric acid, geranic acid, cyanide, freon, nicotine, hydrogen cyanide  and many more.

These all are dangerous for our health as well as our environment. Danger of smoking is wider than we thought. These elements burns and create smoking air pollution which will directly affect the atmosphere.  Our climate is changing rapidly so we have to be more conscious.

Smoke pollution

The answer of the question “does smoking pollute the air” is easy. Yes, it does. But the problem is we don’t know how much it pollutes.

It is generally thought that cars can do great harm to air pollution. No one would think that a small cigarette can do harm to environment then a car. I mean, think normally that a small cigarette vs a huge car. No match, isn’t it? But guess what: smoke affect the environment ten times higher than the car smoke which runs by diesel.

In a recent survey, scientists has found that smoking is one of the causes for destroying ozone layer on our atmosphere. By now you obviously know that how important ozone layer is for our environment. The layer of ozone is protecting us from harmful sunbeams and some of us is destroying this layer of protection very slowly. There are some chemicals on cigarette which destroy the ground level ozone layer.

I think I can make you understand that ozone layer is good for us and smoking is destroying that. Now matter of fact that ozone layer is destroying for some other reasons also, so why smoking is so special? Ok, think about that the ozone layer is protecting us from many defective cosmic rays which usually filtered by ozone layer.

The dangers of smoking

Because of the position of ozone layer is not near of us and the bad effect of cosmic rays is not rapid, we cannot feel the problem all the time. Here is the dangerous part of cigarette smock comes near. By smoking people are destroying the Ground-level ozone layer.

The effect of this is so far reaching & effective that we could easily understand the consequence of this bad habit.
Now let’s discuss about another reason of smoking bad effect. When a smoker inhales a cigarette, he does several tasks. He create pollutant call smoke, burns tobacco, it also burns oxygen.

Smoke creates 7-24 milligrams of pollutants all over the world round the year. While inhaling a cigarette a smoker also burns oxygen with every breath the take. It seems simple to hear but what would be your thought if I would tell you that 1.1 billion smoker burns oxygen while smoking only in United States?

Are you serious now?

Then please be informed that the statistics that I gave before was for the year of 1998 in this air pollution essay. At present what would be the number have you ever imagined?  Whatever the number is but the matter of fact that smoking is causing serious air pollution for sure.
