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 »
