  • Waste Classification

We offer the best solution in either case for new installations or modernization of existing installations, in manual, semi or fully automatic version.


Composting is the transformation and stabilization of the organic fraction of the residue under controlled and thermophilic aerobic conditions.

The aerobic process is provided allowing fermentation.

We have a wide range of options that allows us to offer solutions in composting outdoors, in boats or in confined and deodorized tunnels with automatic loading and unloading. We can also design and build fixed or mobile lines designed to refine the quality compound.


The Collection of Waste is carried out through containers in the majority made in the Populations, Services and Industry, each with a specific product, such as plastic, paper and cardboard, packaging, glass, organic matter, etc.


Ecopark is a clean point where you can deposit the waste generated in the house, such as antique furniture, computers and electronics, Kitchen Oils, Industrial Oils, Clothes, Glass, Wood, Debris etc.

Ecopark does not behave like a dump but as a selective waste separation it also does not generate odors and organic waste that it does not support and are not as hazardous as toxic waste is deposited in special containers.


It is the process in which the microorganisms break the biodegradable material in the absence of oxygen. This process generates several gases, including carbon dioxide and methane, are the most abundant (depending on the gradient material). In this gas digesters release before being used as fuel fails. The intensity and duration of the anaerobic process vary depending on the various factors, which include the temperature and pH of the biodegradable material. The end of the process is to produce biogas that is burned in internal combustion engines to generate electricity that is reused in the same plant or sold to the local grid and as a by-product, hot water from the engine cooling and which is susceptible to be exploited for industrial applications


Residue transformation in a set of homogeneous materials, almost half of the waste consists of non-fermentable materials called inorganic (paper, cardboard, plastics, glass, fabrics and other wastes). The classification of these materials is done manually or completely automatically to recycle and recover.

The remaining organic wastes must be processed in other processes, such as anaerobic digestion or composting, as inorganic fertilizer adjuvants.


Such facilities are responsible for eliminating uncontrolled landfills, preventing pollution of rivers and groundwater and reducing treatment costs. They are the key element in reducing transport costs in case of long distances between waste collection points and treatment facilities. They also promote integrated solid waste management in major cities, towns and villages that are far apart. The essential mission of Transfer Plants, which accumulate solid waste, is to optimize the high cost of long-distance transport. There are Municipal Solid Waste (RSU) produced by vehicles of household garbage collection, conditioning them in others with a much larger load capacity, designed for heavy transportation, which allows movement for disposal or treatment, in good conditions and regardless of the distance traveled.

Cheaper Transport Costs due to:

  • The Fuel used is reduced to a single vehicle capable of transporting and evacuating that employs several garbage trucks in the same operation, with a greater number of trips to the landfill.
  • Not having to move the collection vehicles for long distances, the staff employed in it does not suspend your truck from workload litter, waiting for who makes its way, so the same team and at the same time, you perform a larger household waste collection.
  • Less wear and tear of the equipment is produced and therefore a reduction in maintenance costs (repairs, replacement parts, tires etc.)
  • The purpose of a transfer plant is to serve the mediation transfer between a system for short-term medium to low capacity collection / transport vehicles for high-capacity containers in which media vehicles with easy handling for loading and unloading , transport (long distance) is made to the waste treatment center, giving a total cost optimization management to the facility's catchment area.

Once the Municipal Solid Waste Transfers are collected in the intslações, and transferred to closed containers, they are transported to the central vehicles qualified for sanitary landfills. The characteristics of a plant transfer are:

  • Ease of entry and exit for both collection and long-distance transport vehicles.
  • High maneuverability within the enclosure to allow unloading of collection vehicles and large capacity models.
  • Minimum download times by loading collection vehicles for the long term.
  • The required compression for the number of trips to the treatment center is minimized.
  • Facility flexibility to support all types of waste called Solid Waste or equivalent.
  • They bring together in their design and operation all sanitary conditions for legalization force and do not represent any type of aggression to the environment.


A sanitary landfill is a waste disposal site or waste site where multiple measures are planned to reduce the problems caused by other treatment methods such as landfills, such as meticulous environmental, economic and social planning and Site selection for site survey and monitoring throughout the life of the landfill impact.

To build a landfill it is important to select the field that provides adequate technical conditions, such as topography, groundwater level and availability of material to cover the garbage.

In a landfill, as well as the placement of garbage, it is packed with equipment and covered with a layer of soil and other materials for later covered with a layer of soil that is about 40 cm thick and deposits another litter of layer and so on until the landfill is given by saturated.

It is an Engineering method for the disposal of solid waste in the soil so that the environmental protection is given by the dispersion of waste in thin layers, compacting the smallest possible volume and covering them with soil at the end of the working day avoiding effects adverse effects on the environment.

In addition, as a way of minimizing the environmental impact and how the implementation of the Kyoto Protocol includes landfill leachate treatments, which are produced by liquid waste, burning of decomposition gases, mainly methane, landfill area for reforestation and odor control . Because untreated confined waste containing a high potential risk to the environment (damage to waterproofing over time), in Europe already have rules that require waste treatment before proceeding to eliminate the potential hazard to both the environment and human health .
