Despite this problematica, feasible measures exist to reduce the impact of landfills:

1. Trash compaction can reduce energy costs and economic transportation and disposal. With today’s technology can reduce waste volume by 60%.

2. Pneumatic conveying systems are available that can reduce density in areas of high costs.

3. The problem of leachate can be reduced with proper planning of the location of the landfill away from aquifers and surface water bodies. Parallel systems are essential to capture leachate drainage and undergo treatment. This can be: Read the rest of this entry »

As a result of treatment received reduces the environmental impact of uncontrolled dumping. By coating the waste with soil reduces the proliferation of pests and odor emissions. Since there is no uncontrolled waste burning reduces air pollution. However, there are still many drawbacks:

1. Occupation of the territory. Landfills occupy large tracts of land relatively close to urban centers. By some estimates the waste produced by a population of 10,000 people a year would occupy an area of ??one hectare to 1.2 m deep. The greater the distance increases transport costs increase proportionately and emissions of greenhouse gases produced in transport.

2. Landfills often occupy valuable ecosystems. Occasionally, moist areas of high ecological value have become landfills. Read the rest of this entry »

Once all the other treatments there is still a fraction of the waste called rejection, which could not be recycled or recovered, and whose final destination is the landfill.

A sanitary landfill is considered controlled when taking measures to avoid to be harmful, disruptive or cause damage to the environment.

Depression consists of a natural or artificial terrain in which are dumped, compacted and covered with soil daily accumulated debris. Basically it is a biological treatment of waste. Read the rest of this entry »

The valuation has a number of advantages:

- Reduction of waste volume by up to 90%.
- Energy recovery.
- The ashes are more stable than the starting waste.

Energy recovery from waste is getting energy from burning. The calorific value of waste is variable, in the case of hydrocarbon plastics is estimated to be comparable to that of the oil with some environmental benefits as not to generate sulfur oxides, which cause acid rain. However, the combustion of PVC generates a 50% energy than before. Read the rest of this entry »

Incineration of waste is widespread in some countries like Denmark, which burned up to 56% of MSW. The Netherlands and Sweden, 30% incinerated and the United States only 16%. In our country there are 22 incinerators that burn a 6% waste.

Incineration is the total oxidation of the excess waste in air at temperatures above 850 ° C according to European standards. It is done in ovens or not appropriate to use the energy produced in which case we speak of energy recovery.

The elements of an incineration of municipal waste are: Read the rest of this entry »

If you want to help your loved ones live a greener lifestyle, consider solar powered gifts. Obviously, those who you wish to give solar alternative energy will need to be willing to make the switch. However, most people fully realize how beneficial these systems can be, and will be thrilled to have their own. For many, this is the ultimate gift, as the benefits will continue to be made known each month.

You can choose a contractor who can supply the panels and complete the solar panel installation. The contractor will be able to work around any schedule, and can work to meet deadlines for special occasions. Speak with the contractor of your choice should you have any questions or special requests. Making this switch is now easier than ever, and a complete changeover can be completed in very little time.

For those who do not understand how solar energy works, you may need to explain to them that these green energy systems can be just as powerful as standard energy. Many people still do not understand that this switch will not result in a decrease in their quality of life. Change can be hard, but when the change is beneficial, it will be much easier to adjust to. Helping others, while helping the environment, will most certainly allow you to feel great about giving the gift of alternative energy.

Treatment of the carton.

They are recycled in two ways:

- Recycling set. Resulting in an agglomerated material called Tecta ®.
- Recycled separately. Prey components independently.

In the latter separate the cellulose fibers of polyethylene and aluminum in a hidropulper by rubbing. After the procedure is flushed from the bottom hidropulper Through a filter that lets the water and cellulose fiber.

With the recovery of it was recycled to 80% by weight of the container. To get the rest can be recovered jointly obtaining a reinforced polyethylene pellets aluminum. This residue is also used as fuel in cement kilns, since polyethylene is a good fuel and supplies the oxidized aluminum bauxite, cement ingredient. Read the rest of this entry »

Treatment of paper and cardboard.

Recovery consists of cellulose fibers in aqueous solutions by separation of the surfactants are incorporated in order to remove the ink. The ink remains on the surface of the bath and can be separated easily.

After removing the ink, the suspension is subjected to a drying fibers on a flat surface to recover. After they passed through rollers that flatten and compact, finally leaving the sheet of recycled paper.

Treatment of metals.

Tinned steel containers, better known as tin, are perfectly recyclable, are used in the manufacture of other containers or scrap in steel foundries detinning after being tin. All recovered steel is recycled by the needs of the mills. The process of recycling of tin reduces energy consumption in a very notable. Read the rest of this entry »

Plastic containers can undergo three types of processes.

- Mechanical recycling.
- Chemical recycling.
- Energy recovery.

The first is to chop the material to enter it later in an extrusion machine to mold-granceadora later by traditional methods. Only be applied to thermoplastics, which are those that melt by the action of temperature. It has two fundamental problems. The first is that the plastic used and loses some of its properties makes it necessary to use in the manufacture of other products with less requirements. The second is the difficulty in separating the different types of plastics. This will have developed different systems. Read the rest of this entry »
