The users who use or consume refrigerant gases, and who generate residual refrigerant gases, do not have clear guidelines on the environmentally appropriate management of a residual container or container that had contained this type of substance with a hazard characteristic. This situation is duo to there have not been inventories, studies, physicochemical analyzes, and there are not information that has been collected or systematized in where it concrete or evidence the conclusions related to the recipients danger. The foregoing is because it has assumed that the refrigerant gases that are or have been in contact with these containers, have a physicochemical characteristic of danger different from those related to CRETIP (corrosive, reactive, explosive, toxic, flammable and infectious). This physicochemical characteristic is not intrinsic to its composition, because it generates a direct impact on the environment; this danger consequences are relationship to the degradation of stratospheric ozone and global warming caused by the release into the atmosphere of these molecules. Likewise, on the refrigerants handling, it has assumed that according to the thermodynamic characteristics of these substances, a part of these containers are discarded by the users have residual refrigerant gas. But there are another part that do not contain residuals refrigerants, because the gas is evaporated by low temperatures and they are going to generate emissions to the atmosphere due to anthropic activities, or because it is not totally injected into a refrigeration and air conditioning equipment. These differences influence the elements and procedures required for the environmental management of these wastes. It means that the sector that handling and the end users that consume these substances do not guarantee the integral management of this type of waste generated. For that reason, it is necessary to characterize, classify and identify these residual non-refillable containers. It is in order to define, if the strategy of use and recovery of this waste can be carried out by a user or by the air conditioning and refrigeration (RAC) sector, or must be performed by a hazardous waste manager licensed for the environmental management of these particular wastes. The academic background of this project refers all about refrigerants gases and their container (cylinders), but since point of view of its life cycle. For this reason beginning the documents explains the environment impact and associate definitions of this chemical substances imported our country and how the international and national regulations is implemented to the elimination plan of these substances in Colombia. Furthermore the document emphasizes on useful and consumption of refrigerants gases of manner that the document identifies the most important sector that use these refrigerants and describes the hazards waste classification that there is for these virgin or new substances nowadays. Finally the academic background explains all related to waste refrigerants gases according to national rules as well as explains the strategies and the good environment management that there is in the country for this waste. Once the information about importations were recollected and analyzed, this study determined the number of rechargeable cylinders per years taking into account the significant refrigerants gases those are imported to country. Likewise study determined the weight of empty cylinders and calculated the weight of metal that generate the no rechargeable cylinders when these be convers in metals. Defined the sample of this project the study identified that the not rechargeable cylinders that were thrown away by RAC sector with closed valve have remains of refrigerants these value are between 0.096 kg to 1.25 kg. After that study made the analysis related to the waste characterization of these containers (cylinders) according to national regulation (Resolution 062 del IDEAM). The analyses that were selected for making this hazard characterization were: Flammability a Toxicity test. These analysis were selected according to the hazard characteristic that have the refrigerants like chemical substances or new. Flammability test permitted to determinate of flash point of refrigerant’s remains that are into the no rechargeable cylinders. For this testing the cylinders were heated and were putted in contact with an ignition source. Flammability test resulted to presence with of flame for all cylinders in a range of temperature between 26°C to 31 °C. This results confirmed the hazard by flammability that has the not rechargeable cylinders. On another hand, toxicity testing permitted to classify this complex waste as a hazardous waste by aquatic toxicity. The testing consisted in calculate the reduction percentage of growth of green alga unicellular (species: Selenastrum Capricornutum). In essence, this study accomplished to determine the dangerousness of not rechargeable cylinders that were been used for storing refrigerants gases HCFC (R22) and HFC (blending of HFC as: R404A y R410A). The above, due to the results following: – Due to the remains of refrigerants what are content into the not rechargeable cylinders these recipient are considered hazards for environment. This hazard is caused for releasing of these remains of refrigerants, that produce ozone depletion and increase the greenhouse effect our planet. – The same as the last hazardous, this container or not rechargeable cylinders that are smeared by HCFC and HFC refrigerants is considered flammable. – According to toxicity testing that was made by this study the not rechargeable cylinders with remains of refrigerant gas are classified as ecotoxicity waste because they are toxic to environment. Finally, once characterized, classified and quantified this hazard waste this study determined the appropriate environment management for this waste. So it could be applied in two strategies: – The first strategy is applied into the waste generation element and as an action for preventing of the industrial pollution so that good practice refrigeration has to be strengthen in order to include all procedures needed for empting totality refrigerants of the not rechargeable cylinders. – The second strategy is related to the reuse and appraise these waste. Once they are considered a waste by generating companies it is necessary apply all procedures that were defined in this study in order to recover the remains of refrigerants and avoid the pollution to atmosphere. Thus refrigerant gas could use again and the empty container could take advantage of like ordinary waste.
