The notion of garbage is isually applied to solid residues, but a lot of things considered garbage can be reused and recycled. Beyond creating work, recycling reduces the demand of material matter and energy, contributing to the decrease of sanitary landfills.
In this work , we are going to present whick kinds of garbage exist, where they go and which processes they are submitted to. Also the rule of the 3’Rs and explaning who the garbage workers are and what you can do to help the environment, reducing your ecological footprint.
Household waste Industrial waste Public waste Medical waste Nuclear waste Public waste Trash can be organized into different categories. In what refers to its chemical composition we have: - Organic residues and inorganic residues In what referes to his source we have the examples above.
Household Waste In this category are included leftovers, plastic, metal, glass, paper (packaging, cans, bottles, newspaper, magazines) etc. When improperly accumulated, organic waste can become highly polluters of soil, water and air. Besides that, the inadequate arrangement of waste creates an environment propitious to the development of pathogenic organisms.
Is generated by the industry like metallurgical, chemical, petrochemical, paper, food, etc, and it can be highly prejudicial to the environment and to human health. The industrial waste is quite varied, as it can be
Medical waste Is the classification given to dangerous residues produced in hospitals, like syringes, aprons, etc. By containing harmful agents this kind of garbage is separated from the rest of the residues produced in hospitals (leftovers, etc), and it is generally incinerated. However, certain hospital supplies, like aprons that were into contact with electromagnetic rays of high energy like X rays, are classified in a different way (the apron is considered nuclear waste) and have a different treatment.
One fish asks to another: What is that, acupunture? And the other answers: No, is medical waste thrown in the river
The construction of landfill sanitation requires a previously installed water resistant, which disables the liquids from infiltrating the soil. The remaining fluids are then sent to a treatment facility in order not to damage the environment.
This process reduces the garbage to ashes. In the past century this was a common practice and is extremely polluting, generating carbon dioxide and greenhouse gases. It is used on the destruction of hospital waste because they contain harmful agents and virus contamination risk.
Recycling reduces the volume of garbage, which contributes to reduction of the pollution and contamination, as well as in the recovery of the natural environment, as saving the material matter and the energy used to manufacture other products.
Each one represents one group of people that are essential for making sure that recycling happens. The first arrow represents the producers , the companies that make the product. The second arrow represents the consumer , the people that buy the product. After being used, the product can be recycled. The third arrow represents the recycling companies that collect the recyclable products and throw the market, sell again the used product so the producer transforms it into a new product.
Three arrows compose the Recycling symbol
Recycling does not hurt. It helps the environment !
I’m sure you have already thought how unpleasant leading with trash is. And also have thought how garbage workers ‘can’ work all day smelling the unpleasant odors of garbage accumulated in the trucks. Yeah, it isn’t really easy. Therefore, we must recognize the important role of these people that clean the city. And how they make your own life much easier. Imagine if each one of us had to take our garbage to a safe place and away of our eyes every day.
Your responsibility about garbage doesn’t end up packing it in plastic bags and placing it at your doorway to be taken to somewhere” (the destination of garbage).
Garbage must be packed properly to offer:
- Safety ( do not throw aside on dump
what you consider as dangerous or toxic)
- Resistance against sharp objects
- Easy of handling by the user and the collection team
On the contrary , it can cause accidents to employees, making the service slower and consequently more expensive (due to the necessity of joining the garbage shed and increasing the time of collection, thus spending more fuel), or it can cause malfunction on the equipment (objects that may enter the engine or corrosive substances).
People that live on collecting garbage from large and small cities rend one of the most important services to the society. They help recycling materials, which have a recognized environmental value. But the same society which benefits from this kind of work still does not give these workers due recognition.
The first barrier to overcome is undoubtedly, prejudice.
And it starts in the moment when it is denied to these people the status of workers. For many people those are simply ‘unemployed’ that in situation of poverty, collect garbage for living. Actually, these people are inserted, like any worker, on the productive sector of the economy.

The ecological footprint is a measure of human demand on the Earth's ecosystems . It compares human demand with planet Earth 's ecological capacity to regenerate. It represents the amount of biologically productive land and sea area needed to regenerate the resources a human population consumes and to absorb and render harmless the corresponding waste. Knowing that the Earth’s Regeneration capacity is about 15.7 acres per capita, it is possible to estimate how much of the Earth (or how many planet Earths) it would take to support humanity if everybody lived a given lifestyle.

drive-through-park the car and walk inside instead.
Have your vehicle serviced regularly to keep the emission control systems operating at peak efficiency. Check your car's air filter monthly, and keep the tires adequately inflated to maximize gas mileage.
Avoid short airplane trips,take a bus or train instead.
Buy less! Replace items only when you really need to.
Recycle all your paper, glass, aluminum, and plastic. Don't forget electronics!
Compost food waste for the garden. Garbage that is not contaminated with degradable (biological) waste can be more easily recycled and sorted, and doesn't produce methane gases (a significant greenhouse gas contributor) when stored in a landfill.
Buy recycled products,
particularly those labeled
Conclusion After knowing where the things we throw away go, and what processes they suffer, it is possible to affirm that the elimination and treatment of our garbage is one of the most contributing factors for the pollution of the atmosphere, and sometimes (several times),water and soil pollution, when inadequately thrown away. Also after knowing a little bit more about the garbage workers, we think we need to be more respectful to them, once that they rend a dirty function, which the only goal is to serve society, cleaning her garbage and keeping it away from our door. Daily dealing with dirtiness and bad smells.
Changing our lifestyle is a goal to achieve. Not only you, but a huge amount of people. If you can start, others can start too. We gave you a little list of choices that will help the environment, and yourself.
Please change, it is up to you to make this place a better place, if you don’t do it then no one will, never say can’t, never rely on politics or promises, take your action before it’s to late, and most importantly, never give up the cause, never surrender, for a better future and for a better world.
