Τhe Underground Waste System is a product that enables successful and rational organization of collecting, sorting, removal, treatment and disposal of municipal waste. It promotes the work of the municipal system and significantly improves the quality of the environment. The experiences of the cities in which the Underground Waste System are installed confirm that the design of the product meets the high aesthetic requirements, that are easy and quick to install, easy to load and unload, easy to maintain and easy to operate.

Underground Waste System is certified according to the standards that apply to this type of product, it is patented  and the law protected product. Company provides quality service and maintenance of its product.

Environmentally friendly Underground Waste System is manufactured using the following materials:

The success of the Underground Waste System lies in its superior holding capacity and environmental protection attained, over traditional surface waste containers. Storing waste in Underground Waste System has many added benefits besides a large capacity and a more visually-appealing experience: 

  • reduced service frequency
  • less truck traffic 
  • lower CO2 emmisions, 
  • lesslitter in our surroundings.

With the majority of the waste underground, Underground Waste System  create a naturally pest- and bacteria-resistant environment.The fact that the waste is underground and inaccessible, combined with tightly locking lids, act as pest deterrence, helping to create a clean environment that discourages animals and insects from gathering. By storing waste underground, the Underground Waste System not only prevents pests from accumulating, but also bacteria as well. The colder temperatures underground deter bacteria from forming and thriving. And, as an added bonus, this is achieved in a natural, environmentally-friendly manner—no chemicals or other damaging solutions are necessary. Ultimately, for the end user,underground waste solutions will emit lower odors and attract fewer pests, resulting in a positive experience. The Underground Waste System is waterproof and leakproof, protecting the surrounding soil from contamination. It is designed without  the possibility that the contents get in the groundwater.


Reduce costs related to fueling, vehicle wear, and working hours, avoiding collection of empty and half- empty containers and eliminate excessive environmental footprint with dynamic routing based on reported fill levels. Maximizes benefits of Underground Waste System KORALI , enables manage of waste more effectively and more efficiently.

Automatic monitoring of Underground Waste System provides temperature measurements, measurement of waste occupancy in container and speech processor which enables the pronunciation of the different texts when the lid is opening for waste disposal, permitting intelligent route planning for collections ensuring no visit is wasted.

Battery lifetime 2 years.


With the right use of underground containers:

  1. The product life span is extended.
  2.  We provide a complete selection of raw materials and organic waste.
  3. Avoid burning the contents of the container.
  4. The environment is cleaner, safer and more beautiful.
  5. We create significant financial savings for customers, local communities and municipal businesses

 The underground container is filled by depositing the waste through the opening in the low-closing lid with instructions for use.

The inner bag is evacuated by removing the lid with the help of a hydraulic crane in a typical garbage truck. The evacuation takes place above the loading trailer or hopper that receives the waste and directs it to the presses for condensation. The bag is opened at the bottom, pulling the rope, releasing the waste from the bag with all its weight, without the possibility of the contents remaining in the container and without the possibility of spilling the contents onto the truck and the ground. The bag is then closed by pulling the rope to the restrictor allowing the bag to approach the predetermined manner that defines a container for residual / compressed liquids. The rope is then secured by the mechanism that prevents the accidental opening of each bag. The bag returns to the shaft, a large lid is placed in the housing of the container in its original position before the container is emptied. Removing the container and returning to its original position takes up to 3 minutes.

The evacuation of underground containers can be carried out with the help of a variety of equipment, including existing waste tankers, by refurbishing and upgrading the hydraulic crane with specific features and a removable waste hopper. Existing equipment remains operational for the evacuation of standard containers. However, the best solution for evacuation is the new generation of refuse containers which are fully equipped for lifting and evacuating underground containers with the help of remote controls. Depending on the needs of the customer, there is available and additional equipment for monitoring the container from the central and evacuation vehicles. only containers can be fitted with a radio link that provides full cost-effectiveness
