Renting a dumpster to clean out and dispose of junk and garbage is the best way to bring a large quantity of unwanted junk to the landfill. But one question people may ask thmeselves is, how is such a landfill manage to optimize its waste management processes and reduce pollution?
The major role of a landfill is to separate the buried waste and its environment. However, whether the burial method is by backfilling a zone with relief hilly or by creating a tumulus overhanging the natural ground, the precautions to take and the adjustments to be made will be similar.
Before any spill of waste, the landfill will be insulated at the base and on the sides by means of layers of waterproof materials. Drainage systems will also be put in place way to collect leachate. During filling by people using a dumpster near me or other means of waste disposal, degassing wells will be high in order to allow the collection and treatment of the biogas produced.
At the end of operation (and sometimes even during operation, in the case of cells for example), the containment of the waste will be ensured by a cover mineral and/or earth to limit the risks for the population and the environment.
Among the development works to help from dumpster rentals and other trucks bringing garbage, it is also necessary to consider the devices making it possible to control the impact of the landfill on the environment, namely the piezometric wells surrounding the site in order to control the level and quality of the water in the aquifers as well as nearby air and surface water quality analysis stations of the site.
Waste management research shows all the general characteristics development of the landfill. The basis of the landfill, the safety barriers that are placed on the natural terrain at the base of the landfill, including including the sides when the latter is concave in shape, have the function of protecting soil and aquifers against contamination by leachate. We distinguish two types of safety barriers: static sealing barriers or geomembranes plastic and dynamic or clay barriers.
The care with which the background of the landfill will need to be prepared however depends on the environmental conditions. The presence of impermeable soil layers satisfying the criteria and the climatic conditions are factors which will be taken into consideration.
Indispensable, the establishment of a clay barrier, in addition to the impermeable layers fulfilling the minimum conditions for installation, can be made using natural materials (natural clays), materials geocomposites (such as bentonite swelling clays) or a mixture of the two.
The creation of the clay barrier is done by compacting successive layers of homogeneous material (comprising more than 15% of particles passing to 2 µm including more than 10% of swelling agents, more than 30% of particles passing to 60 µm, less than 10% refusal at 10 mm, no element larger than 50 mm, less than 1% organic matter with a carbon/nitrogen ratio less than 20) and at an optimum plasticity (liquidity limit less than 80%, plasticity index between 10% and 30%, even 40%) in order to ensure a certain homogeneity and continuity of the material.
On the floor surface of the landfill, we define zones (called cells) of approximately 50 to 200 m on a side depending in particular on the conditions for the implementation of leachate and atmospheric water drainage.
Each cell will be crossed longitudinally by a slight ditch which will then accommodate the main drain (possibly made up of several cheaper parallel drains). A certain profiling of the clay barrier must be respected in order to print, on both sides of the ditch, and along the ditch itself, slopes of 2 to 5% to allow the flow of liquids and the laying of secondary drains.
After installation, the waterproofing barrier dynamic will have a minimum thickness of 50 cm and will be at least equivalent to a layer of clay with a thickness of 1 m having a coefficient of permeability 10–9 m/sec.
In practice, analyzes and laboratory tests must be carried out to select the materials and determine the conditions for work in terms of humidity, density, compaction, etc. On-site tests after installation use dumpster rentals will also be carried out in order to assess the installation and guarantee the required seal.
