5 Methods of Waste Disposal

Waste has been a critical problem for man. Everybody produces waste in different degrees and quantities.

For me, one of the best ways of handling this waste problem is to cut down our waste generation.

As we use the groceries, simply buy what you need not what you like. It would go a long way in handling this waste problem.

Another way is to reuse what we have used before, probably turning it into another purpose.

Then the one which is popular but very much essential is recycling. This is simply transforming our waste to become useful in other areas of our living.

As we discuss waste disposal, I would advise we adopt effective methods of waste disposal if what has been briefed above isn’t applicable.

About Waste Disposal

According to Environmental Forensics: An Introduction, Third Edition, 2015

Locating waste disposal sites, figuring out exactly what waste materials were disposed of over time and where, figuring out ownership and deciding whether or not disposal methods were appropriate are all crucial issues in environmental litigation because waste disposal is a process that directly causes a lot of environmental damage.

Waste disposal is the next step in waste management and it involves putting radioactive material in a special facility, though it is also possible to dispose of waste by discharging effluents into the environment within legal bounds.

Methods for Waste Disposal

The following are some of the methods of waste disposal techniques:

  • Landfill
  • Incineration
  • Biogas Generation
  • Composting
  • Plasma Gasification

1. Landfill

Non-reusable and non-recyclable materials are spread out in a thin layer in particular low-lying lands or places as part of this operation.

There is a barrier around landfills that keeps any chemicals or toxins from leaking into the groundwater.

Each layer of garbage is compressed before being covered by a layer of soil, an impermeable one.

When waste is disposed of inside these places, they are dug deep, and then a layer of soil is utilized to cover them up.

For the next 20 years, these regions are deemed unsuitable for building-related activity.

Shortly, parks or playgrounds could be constructed on the land.

It is one of the most widely used strategies for disposing of waste in large quantities.

2. Incineration

Incineration is the process of treating waste or disposing of waste by burning it and converting it into incombustible materials like gases and ashes.

Heavy metals produced by incinerators are thought to be extremely hazardous to the environment since they are dumped in landfills, polluting the air, water, and soil.

However, there are a lot of advantages to this procedure, such as reduced waste volume, power and heat production, pollution reduction, no need for waste transportation, control over noise and odor, and eradication of chemical and hazardous germs.

3. Production of Biogas

Food products, animal waste, municipal garbage, fruit and vegetable peels, and organic industrial wastes are all examples of biodegradable waste, which means that bacteria or other creatures may break them down.

Both small-scale and large-scale biogas production using these wastes is possible, and the materials are easily broken down by bacteria, fungi, and other microbes.

Microorganisms eat the organic, biodegradable material that must be broken down or degraded. Both anaerobic, or without oxygen, and aerobic, or with oxygen, methods of producing biogas are possible.

The process produces biogas, which is utilized as a fuel, and the waste is applied as a fertilizer to farms and plants.

Methane and carbon dioxide make up the majority of the gases that make up biogas.

Since the wastes are used to create something useful, this type of waste disposal is advantageous.

4. Composting

One technique of waste disposal that starts in our kitchen is composting.

All organic waste, such as leftover food, yard debris, and fruit and vegetable peels, is handled by it.

These materials decompose after being buried and left in the soil for a few days thanks to the activity of bacteria, fungi, and other microorganisms.

As a result, decomposition occurs and compost, a substance resembling hummus, is created.

As it is nutrient-rich and may replenish the soil to develop crops or plants, it is extremely advantageous to utilize it as manure or fertilizer.

It is the finest substitute for dangerous chemical fertilizers and is known to improve the soil’s ability to retain water.

5. Plasma Gasification

One of the more cutting-edge methods for dealing with plastic trash is plasma gasification.

Although it uses more energy than, say, dumping rubbish in a landfill, it is a useful method for lowering the volume of waste and ensuring that we aren’t reliant solely on landfills to dispose of it.

Plastic is first shredded before being transferred to a furnace that has been preheated to about 1,500 degrees Fahrenheit to begin the plasma gasification process.

This is then combined with steam and oxygen, which successfully vaporizes between 75 and 85 percent of the trash.

The remaining mixture of gases is called “syngases” (because it is synthetic natural gas), and the remaining waste is removed from it.

Then, another furnace is used to heat the waste to an astonishing 18,000 degrees Fahrenheit.

Due to the extreme heat, the residual waste is broken down into its component atomic elements.

Any remaining material is transformed into slag, tightly-bound solid waste bricks that can be used in building.

This means that major organizations pursuing zero waste practices may use plasma gasification.

It may be a good idea environmentally speaking to be able to vaporize into useful components given that nations like the US produce about 250 million tonnes of garbage annually.

However, the procedure is very expensive and energy-intensive. Only a few websites worldwide provide it, making it another uncommon practice.

Plasma gasification might become a crucial waste disposal technique in the future because of technological improvements that have made it simpler to put into practice.

Importance of Waste Disposal

The following are the importance of waste disposal

  • Facilitates Organization
  • Landscape Cleanup
  • Encourages cleanliness and good health
  • Lessons infection with pests
  • Guards you against biohazards
  • Promotes community health
  • Prevents environmental damage
  • Makes physical safety a priority
  • Increases energy waste
  • Brings in income

1. Facilitates Organization

The influence of efficient garbage disposal on your space should be your primary motivation.

You can make sure your place stays tidy and clean by designating a space outside, inside, or even inside your home or business, and by having your trash cleaned up regularly.

You have more space to organize and move around if your home or office isn’t filled with clutter.

2. Landscape Cleanup

A backyard is a common place for homes to store clutter, including outdated furniture, damaged appliances, and large items of trash and debris.

Your landscape becomes chaotic as a result. It lessens your house’s curb appeal.

Additionally, it provides the ideal environment for rodents and other pests to reproduce.

Whether it is your garden or your sidewalk, proper garbage disposal helps clean and clear your landscape.

Skip bins positioned wisely will assist you in keeping up your appearance.

3. Encourages cleanliness and good health

Health and sanitation are two of the main issues with trash disposal.

Waste that is fermenting and decomposing serves as a haven for germs and mold.

Your home is susceptible to the spread of disease without adequate trash disposal.

Skin rashes, allergies, or even worse issues might result from improper garbage management, which can include dispersed trash or late skip bin hiring pick-ups.

4. Lessens infection with pests

Pests like rats and insects are drawn to waste. Particularly, perishables must be removed from the house at least once every week.

To lessen insect damage and to avoid the offensive odor, it is best to have a trash can outside your home.

5. Guards you against biohazards

Hazardous biohazards can be produced by the degradation of metals and chemical waste.

These can leak and contaminate the soil and water, or they might release particles that mix with the air.

Liners that can stop biohazards from leaking out and causing injury are necessary for proper waste disposal.

6. Promotes community health

Before the development of ethical methods for disposing of waste, backyard and landfill fires caused harm to residents.

Systemic illnesses and respiratory issues like emphysema and asthma can appear. Communities benefit more from proper trash management.

7. Prevents environmental damage

Proper garbage disposal not only contributes to your personal and community safety but also protects the environment.

Plastics and mass production of materials are less of a burden thanks to waste control.

Additionally, it encourages actions that don’t add to global warming and climate change.

8. Makes physical safety a priority

Throwing trash recklessly can be risky, especially when it comes to caustic chemicals and sharp materials like rusty nails and glass fragments.

Physical safety can be greatly improved by hiring a trash management business.

9. Increases waste to energy

The community can gain from the energy produced by the burning of waste in some landfills and small-scale facilities, which a lot of people are unaware of.

The disposal process’s waste gases can also be used to generate power.

10. Brings in income

You can supplement your income by sorting trash and locating recyclables, sellable furniture and appliances, and reusable plastic, glass, and wood products.

Top Waste Disposal Problems

Though waste disposal is critical to effective management of waste, below are some of the top waste disposal problems

  • Landfill pollution
  • Flawed regulations and laws
  • Relying on outdated technology
  • Excessive waste
  • Harmful waste
  • Not all green technologies are green.
  • Use of single-use plastics in excess
  • Contamination and improper recycling

1. Landfill pollution

In most landfills, there is inadequate on-site garbage management.

Leachate, the liquid created when garbage decomposes in landfills, is increased as a result of this problem.

The highly poisonous liquid can contaminate the groundwater, surface waters, and waterways.

Greenhouse gases are the following problem. When organic waste, such as food scraps, is dumped in landfills, it is covered by other garbage.

In an anaerobic process, the food waste then decomposes, releasing methane, a greenhouse gas that is 25 times more potent than carbon dioxide.

Another flammable gas that can be hazardous if allowed to accumulate is methane. Yikes.

Additionally, the rules and legislation governing how landfills operate are frequently lax.

2. Flawed regulations and laws

Today, trash management and disposal are lucrative businesses.

Large companies in the waste disposal industry are in charge of running sewer systems, incinerators, and landfills.

Profitability is the company’s main priority, regardless of the requirements for waste reduction.

As a result of their cooperation with regulators with vested interests, waste disposal is ineffectively regulated.

3. Relying on outdated technology

Instead of creating efficient recycling and trash reduction programs, waste disposal and management facilities rely on fast, ineffective, and out-of-date technologies.

Regarding more recent and cutting-edge technology that can lower the amount of trash, the majority of states and nations are hesitant.

4. Excessive waste

We produce much too much trash. C&R Lewis Skip Hire claims that this is one of the major issues with waste disposal.

According to a survey, America generates 220 million tons of waste annually.

And that’s just for America. When we add the rest of the planet, consider how little that number is.

The issue is also largely attributable to businesses that make one-time products but do not prioritize recycling, reusing, or using eco-friendly materials.

5. Toxic and Harmful waste

Most municipal and state governments are relatively lax when it comes to controlling toxic substances.

Numerous items in your home probably contain harmful compounds, and sadly, many people use numerous poisonous products daily, such as:

  • Solvent-based paints
  • Pesticides and other garden chemicals
  • Batteries
  • Cleaning and polishing chemicals

They are frequently disposed of improperly, endangering both our health and the environment.

According to a U.S. EPA analysis, our houses’ consumer goods contain more than 60,000 untested chemicals.

And this is the only thing that our consumption generates. Therefore, the amount of pollution produced by businesses and industry is a major problem.

6. Not all green technologies are green.

Several recycling methods are deemed “green.”

But upon closer examination, they aren’t sustainable.

Gasification, pyrolysis, and plasma incineration are some of these methods.

Burning trash is not the ideal method for getting rid of the rubbish since hazardous substances are emitted into the atmosphere.

7. Use of single-use plastics in excess

As startling as it may appear, a significant portion of plastic trash (around 40%) comes from single-use packaging.

Single-use plastics can be replaced with more environmentally friendly options.

For some reason though, they are still everywhere.

The fact that regulations are being updated and numerous states and nations have ultimately banned certain single-use plastics is encouraging.

Sadly, this doesn’t instantly get rid of all the single-use plastics that have been collected over time.

The largest majority of plastic garbage (40%) ends up in landfills, where it decomposes over a long period.

8. Contamination and improper recycling

Recycling is a very grey area. It has different rules from city to city. And most people don’t know how exactly to handle things.

Even though I spend a lot of time researching various questions on recycling, I still wonder sometimes, and can’t figure out where to throw away certain things.

The problem is that when we mix up our trash, then it is very hard to separate it in the recycling facility.

Plus, mixing trash can contaminate the whole batch, and can make the recycling process difficult and unsuccessful.

That’s why it is super important to find out what you can recycle, and how to separate your trash.

Otherwise, recyclable items will go to the landfill.


Though there are ways we can dispose of waste, still the most efficient way of handling waste is by reducing our waste generation, by that, we will reduce the amount of waste going into the waste stream.
