All this in order to offer the best solution in each case is for new facilities or modernizing existing plants, in manual , semi or fully automatic version , turn key type always with the latest contributions from our R & D.

COMPOSTING PLANTS

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

The aerobic process is provided which permits the fermentation.

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

TRASH COLLECTION

Separate collection of waste is carried out through containers in most populations, each with a specific product such as plastic, paper and paperboard, packaging, glass, organic matter etc.

The goal is to make a shortlist of these materials that are recoverable once processed and that have economic value.

 

ECOPARKS

The Ecopark is a clean point where you can deposit the waste generated in the home such as old furniture, computer and electronics, cooking oils, industrial oils, clothing, glass, wood, debris etc.

The Ecopark behaves not as a dumping ground but as a selective separation of waste also generates no odors and organic waste that does not support and is not as toxic or hazardous waste is deposited in special containers.

DIGESTION ANAEROBIC BIOLOGICAL TREATMENT

It is the process in which microorganisms break down biodegradable material in the absence of oxygen. This process generates various gases, including carbon dioxide and methane, are the most abundant (depending on the gradient material). In this release gas digesters before being used as fuel fail. The intensity and duration of the anaerobic process vary depending on the various factors, which include the temperature and pH of the biodegraded material.

The end of the process is to produce biogas which is burned in internal combustion engine to generate electricity that is reused on the same plant or sold to the local network and as a byproduct , hot water from the cooling of the engine and which is susceptible to be exploited for industrial applications.

 

CLASSIFICATION OF WASTE

Garbage being formed by a set of homogeneous materials, almost half of the waste consists of non-fermentable materials called inorganic (paper, cardboard, plastics, glass, textiles, and other junk ). The classification of these materials is done manually or fully automatically to recycle and recover.

The remaining organic waste materials are to be processed in other processes such as anaerobic digestion or composting, as adjuncts inorganic fertilizers.

TRANSFER PLANTS

Transfer plants are tasked to eliminate uncontrolled landfills, prevent pollution of rivers and groundwater and reduce the treatment costs. They are the key element in reducing transport costs in the case of long distances between points of waste collection and treatment facilities. They also promote the integrated management of solid waste in major cities and towns far between. Them the essential mission of the Transfer Plants accumulate solid waste is to optimize the high cost of long-distance transport. Here come the Municipal Solid Waste (MSW) produced by vehicles home garbage collection, conditioning them in others with much greater load capacity, designed for heavy transport, which allows movement to disposal or treatment facilities, in good condition 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 which employ several garbage trucks in the same operation, with a greater number of trips to the landfill.
  • Having to not move the collection vehicles to long distances, personnel employed therein do not suspend their work load garbage truck, waiting for those doing their path, therefore, the same staff and the same time, you perform a larger home collection of MSW.
  • Less wear of equipment is produced and, therefore, a reduction of maintenance costs (repairs, replacement of parts, tires etc)
  • The purpose of a transfer plant is to serve mediantes compaction transfer between a system for collection / transport vehicles of medium and low capacity with short runs to high capacity containers in which mediantes vehicles with easy handling equipment for loading and unloading, transportation (long distance) is done to the waste treatment center, giving a total cost optimization management for the catchment area of the facility.

Once collected Municipal Solid Waste Transfer in plants, and transferred to closed containers are transported to the central landfill enabled vehicles.
The characteristics of a plant transfer are:
Ease of entry and exit for vehicles, both collection and transportation over long distances.

  • High maneuverability inside the enclosure to allow the unloading of collection vehicles and cargo models large capacity vehicles.
  • Minimum transfer times loading collection vehicles to long haul.
  • Achieve the compactness required for the number of trips to the treatment center is minimized.
  • Flexibility of facilities to support all kinds of waste called Solid Waste or equivalent.
  • They gather in their design and operation all sanitary hygienic conditions for legalization force and do not pose any kind of aggression to the environment.

LANDFILL WASTE

A landfill is a place for the disposal of waste or garbage in which intends to take multiple measures to reduce the problems caused by other methods of treatment such as garbage dumps, these measures are, for example, the meticulous study environmental, economic and social from planning and site selection to site survey and monitoring throughout the life of the landfill impact.

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

In a landfill, as will placing trash, it is packed with equipment and covered with a layer of soil and other materials to subsequently covered with a layer of soil that is around 40 cm thick and this deposit another layer garbage and so on until the landfill is given by saturated.

It is an engineering method for the disposal of solid waste in the ground so that environmental protection is given by the spread of waste in thin layers, compacting the lowest practical volume and covering them with soil at the end of workday preventing adverse effects on the environment.

In addition, as a way to minimize environmental impact and how implementation of the Kyoto Protocol include landfill leachate treatments, which are produced by liquid waste, burning of decomposition gases, mainly methane, plantes reforestation area landfill and odor control. Because confined untreated waste containing a high potential danger to the environment (damage to the waterproofing in the course of time), in Europe already have rules requiring treatment of waste before proceeding to remove the potential danger both to the environment and human health.
