The main components of solid waste are mainly paper, plastics, and other inorganic materials likewise  the composition of solid waste depend on factors such as culture, economic development, climate, and energy sources.

In 2010, Americans generated about 250 million tons of trash and recycled and composted nearly 85 million tons of this material, equivalent to a 34.0 percent recy- cling rate.  On average, they recycled and composted 1.51 pounds out of our individual waste generation of 4.43 pounds per person per day.

a)Plastic bags, paper, wood, plastic bottles, glass bottles, metals, cotton cloth. 

 

b)I think that a total of 70% goes to landfills, 20% to combustion and 10% to recycling. 

 

c)The problem of placing waste is the destruction of the environment around it, and if the waste isn’t removed correctly it will affect even more. 

 

d)Some advantages are that it’s easier to get rid of a lot of waste, but it creates pollution on a big scale. 

 

e)The advantages of recycling are reducing the pollution levels, giving appropriate use to every material we use on our daily basis. Basically you are part of the solution and not the problem. 

 

f)Sheets of paper, plastic bottles, glass bottles, wood, some kinds of metal.

1.-Some components of solid waste can be solid, liquid or few gases materials and those are plastics (toys, bottles water, car tires) oils, latex paint.

2.-In Mexico just the 15% of trash is recycled per year ( the 15% of 80k ton). The fact that the garbage goes to landfills is bad because the garbage in heaps generates gases by adding air, the waste releases liquids and contaminates the soil.

3.-In the landfills chemical and biological reactions created by organic and inorganic matter are created, the substances that the waste releases mostly go to the water and to the polluting soil (leached liquid, methane gas, carbon dioxide).

4.-Burn garbage creates problems, by burning the plastic, the gases released are harmful to health, this would bring problems such as worsening of asthma and lung cancer, the only advantage of burning garbage is that it decreases the trash.

5.-Recycling reduces energy, oil production, we have better control of what we consume, less pollutes recycling.

6.-Plastic, carton, glass, cans, batteries.

As it is known the waste is trash or garbage. It is all the waste that people and the environment throw to the floor and it stays there for a long or few time, it depends in what is it. The mostly components are the paper, cans, pesticides, chemicals, bottles, plastic, batteries even construction and demolition waste are some components of solid waste. 

What are the major problems with placing waste in landfills? 

Landfills are created by land dumping. Disposal methods generally involve the dumping of waste into an area, usually a hole or slope. After throwing away the waste, they are compacted with large machines. When the discharge cell is full, it is sealed with a plastic sheet and covered with several feet of dirt. The major problem is that even if they put everything underground it is still waste for the world and people just can´t throw it underground so they think that it wouldn´t affect anymore, even if it is down, in the street it can still affect us. 

 

What are the advantages and disadvantages of waste disposal combustion? 

Some advantages are that those waste some of them can be useful another time and not only be consider like trash and don´t use it again in your life. There are other things that can be recycled again and it needs to be throw it out, but people should start to throw the garbage where it needs to be and not only anywhere you want. Some disadvantages is that some wastes are very difficult to undo and that it takes a very long time to destroy the material and that can hurt the planet can make that some animals get sick or that an environment start to deteriorate because of that material that takes too long to destroy. 

 

What are the environmental advantages of recycling? 

The advantages of recycling mainly are that people can use again what they don´t use anymore, they can even recycle their clothes even with plastic bottles or only other material that can be recycled again. There are many materials that can be used again and not only throw it to the garbage like if it is not useless anymore. 

 

Examples of materials that can be recycled: 

Food waste, paper, jars, bottles, metals, clothes, batteries, plastic, cans, and many other materials can be recycled to be used another time again.
