Green Dialysis

Recognizing the importance of environmental protection, as well as the fact that natural resources are not inexhaustible, Mesogeios Dialysis Centers have adopted a series of measures and practices to contribute as much as possible to the protection of the environment. The Group has taken all necessary steps in the design of new dialysis units and has also implemented the necessary practices in its daily operations to reduce its energy consumption.

So that our everyday presence may leave the smallest possible carbon footprint on our Planet.

The following actions are taken in the framework of our units’ operation:


To manage waste generated in all Mesogeios centers, it is mandatory by Law to draft an internal regulation for Hazardous Medical Waste management, which is approved by the competent Regional Health Authority. This regulation appoints Supervisors per unit, defines the type of waste produced at the medical facilities and describes the relevant waste management method.

Medical Waste
Medical waste generated during the dialysis process, such as dialysis filters, needles, gloves and anything that may have come into contact with biological fluid cannot be disposed off into the environment as this may entail risks to human health.

All materials that have come in contact with blood are separated, packaged and delivered for neutralization to licensed companies.

Recognizing the importance of proper management of medical waste Mesogeios has become a founding member and principal shareholder of Medical Waste SA ( with the sole purpose of medical waste management.

Units that are not connected to a central sewerage system are equipped with and operate an autonomous biological wastewater treatment plant.

This way we achieve considerable savings on irrigation water, since processed water is used for watering plants in the units’ gardens. Moreover, all cleaning materials as well as the disinfectant used for chemical cleaning of dialysis equipment after each use (Puristeril ®) are ecological and biodegradable.

Apart from medical waste separation, residual waste separation is also carried out. Specifically:

Blue Bin Waste
We actively participate in the effort to recycle plastic, glass and paper through the HERRCO blue bins (Hellenic Recovery Recycling Corporation

  • Paper recycling and cartridge refilling
    When it comes to paper in particular, we make sure to use recycled paper and refill empty ink cartridges. But most of all, we ensure the rational use of such materials

Recycling - Reuse

  • Battery Management
    In cooperation with AFIS SA ( we have placed in all our units special collectors for empty batteries that are known to contain heavy metals which are particularly hazardous environmental pollutants
  • Appliance Recycling
    All electrical and electronic devices that are no longer of use are recycled through the Appliances Recycling company ( instead of being thrown away as garbage.
  • Company vehicles
    All lubricating oils used in ambulances and other vehicles as well as in power generating sets (power generators that ensure continuous and uninterrupted operation of the units in case of power failure) and their packaging are neutralized by licensed companies ( All used vehicle tires are also handled by the relevant waste management companies (
  • Energy saving
    As demonstrated in the relevant section, all company buildings are built and operate in the most environmentally-safe way possible. As to major energy consuming areas, the following actions are implemented:

    • Lighting
      Large openings in buildings facing to the south for natural daylight. Close monitoring for energy saving through lighting (lighting only when necessary, timers, automation, motion sensors in storage areas and WC). Use of parabolic luminaires with electronic dimmer-equipped transformer and fluorescent lamps. Exclusive use of energy saving bulbs and LED bulbs. Act & Do: In March 2009, at our unit in Crete that was built back in 2000, we replaced all fixtures that were using energy consuming bulbs with new energy saving lighting systems.

Cooling, Heating, Ventilation

  • Natural cooling with cross ventilation
    We painted our buildings with light eco-friendly colors to reflect sunlight instead of absorbing it inside the buildings.

    We make rational use of our cooling systems. The air conditioning units installed are of efficiency class A and the refrigerant used is eco-friendly.

    Fresh air is channeled into the buildings maintaining the necessary levels of indoor air quality. Ventilation operates on automated mode but allows manual fan speed adjustment. Double Glazed low-e windows (= 1.3) Low heat gain coefficient (g-value=0.42) High Permeability (Tvis = 0.73).

  • Building Energy Audits
    Since 2008, we have proceeded to the energy audit on the older building of our company in Crete. A series of measures have been implemented and planned to make this building less energy-consuming.

  • Green Business
    The company has received permission from the Regulatory Authority for Energy (RAE) and will build a photovoltaic power station of 79,80 kw on the roof of the Unit in Crete. The use of photovoltaic systems for electricity production is a particularly environmentally friendly technology, but the reduced price of oil for a number of years and the lack of incentives did not encourage their development.

    Nowadays, due to the ever increasing oil prices, the proven negative contribution of the use of mineral resources in the greenhouse effect and global warming, we are ultimately led to this direction. There is undisputable superiority of this new technology compared to conventional electricity generating methods, in terms of environmental benefits:  
    It produces less pollutants, it makes use of domestic and inexhaustible natural resources (in areas with the highest sunshine rates in Europe) and it contributes to the unit’s energy self-sufficiency.
  • Building Construction
    We give particular emphasis on the principles of bioclimatic architecture [for the units constructed by the company].

  • In particular, both the design and construction are carried out with special emphasis on the following areas: 
    The orientation of the units is southwards, where most of the buildings' openings are constructed.  

    • Especially contemplated:
    • • Thermal insulation of buildings
      • The building materials used in construction are materials of increased heat capacity
    • • The frames on the newly constructed units (Serres, Kalamata, Chalkida & Faliro) are equipped with thermal break.
      Heat bridges are avoided on exterior walls and all roofs and bearing structures are insulated.

      Tip: (Proper insulation is the best way to manage heat loss during the winter and the increase of indoor temperature during the summer, thus reducing heating and cooling needs, respectively).

      The selected exterior colors and materials are bright to reflect sunlight instead of absorbing it inside the building which would cause an increase in air conditioning needs.

      Tip (Dark exterior colors tend to absorb heat which is then transmitted inside the building. Light colors reflect a large amount of solar radiation back into the environment and help prevent overheating of the building)

New Activities & Actions

Dialysis Machines

On November 2009, Mesogeios, in cooperation with Mediprime S.A., exclusive representative of Fresenius Medical Care in Greece, began replacing all dialysis equipment in its units and the entire project was completed on March 2011.
The new FME 5008 replaced the older 4008S and 4008B dialysis machines.
Apart from its incomparably improved performance, the new equipment is also eco-friendly.
The equipment’s energy efficiency is of class A verified by Energy Efficiency & Energy Star certificates.It reduces electricity consumption up to 30%, water consumption also by 30% and dialysate consumption up to 25%. 


Staff Awareness on Environmental Issues
Since 2010, our units’ annual staff training programs include a module on environmental education and awareness.

Today, our Mesogeios & Medialyse units employ more than 130 people. 
Except from the eco-friendly designing of the buildings, the staff’s daily practices and habits also prove our dedication to environmental protection.

The aim of these training programs is to teach employees the importance of adopted environmental practices and to support new initiatives and actions by analyzing daily energy-consuming activities.

Green Suppliers
Our company’s supplier evaluation system for 2010 includes criteria for suppliers’environmental compliance, such as:

- Ability to reuse packaging (e.g. The company plans on using 80,000 plastic 5lt acid dialysis solution containers in 2010).

- Suppliers’ environmental certificates (e.g. Medical Waste SA is a supplier that has been certified for its environmental compliance based on EN ISO 14001 as well as ELOT 1801: 2008, OHSAS 18001:2007 and ISO 9001:2008)

- Eco-friendly cleaning materials (e.g. use of ecological materials and chlorine-free materials by Tana & Johnson)
