Metal

General information

In the mid-1980s, for the first time, the European Union introduced measures to manage packaging waste. Directive 85/339/EEC established rules relating to production, marketing, use, recycling and refilling of containers of liquids as well as the disposal of packaging waste.

To address the different environmental impacts of packaging and packaging waste, certain Member States have started introducing measures regarding this issue. As a result, divergent national policies have appeared, a situation harmonized at the European level. Thus, the directive 94/62/ EC was adopted in order for national measures regarding the management of packaging and packaging waste and the prevention or minimization of the consequences for the environment to be harmonized.

The transposition of the Directive into national legislation was adopted under Law 2939/2001, which set out general rules regarding alternative management of packaging waste, the rules for all the participating bodies that are obligated to manage packaging waste, the terms and conditions concerning alternative management of packaging and packaging waste, the conditions of approval and operation of alternative management packaging systems and the principal goals of recovery and recycling of packaging waste at the national level.

Since then, have been many legislative amendments, which developed the contemporary requirements and the “alternative management of packaging and other products”, increasing the percentage of recycling that has to be achieved in order to keep pace with the European Directives. 

Packages are segregated according to their materials in: a) glass, b) plastic, c) paper, d) metal (aluminum, tinplate), which are the most frequent packages. There are also the e) synthetic, f) wooden and g) mixed. 

The production of one tonne of metal requires a great amount of power as well as natural raw materials. This requires the drilling of the soil. Furthermore, we need chemicals in order to properly form the raw material that we will collect from the soil. 

It should also be noted that a can of tinplate will need about 100 years to decompose completely while the consumption of its contents may take us only a few minutes. 

On the other hand, if we recycle our aluminum packaging or cans and then use them as raw material:

• we would be able to save important natural raw materials
• we would need less energy to recreate aluminum or tinplate
• we would cause less pollution to the environment, especially from the use of chemicals 
• we would be able to send much lower amounts of garbage to the landfill. In this way, we could reduce the volume of the garbage sent to the landfill and increase their lifespan. 

We must also be reminded that the greatest harm caused to the environment is identified by the uninterrupted exploitation of the Earth's subsoil for the extraction of new ores, which are not renewed and are not at the same time inexhaustible. 

Through this practice, entire ecosystems have been degraded for many years depriving the flora and fauna of each area of their natural habitat. This includes the plants and animals that lived or could live there in the future. Furthermore, this situation may deprive people of much-needed land that they could cultivate and make a living from.  

Therefore, “source separation” must be applied effectively by citizens. This means that citizens should separate their waste according to its material which should be cleaned and discarded separately in the appropriate bin.
