Waste production

Our lifestyle is highly polluting.

Economic prosperity has brought us to behave carelessly and irresponsibly towards the environment.

This has led to a high level of waste production


Waste production

To prevent an excess of pollutionweshould:

-Avoid disposable products

-Buy products with little packaging

-Drink filtered water from the tap

-Reuse and recycle


Waste production

Waste can be

burned in incinerators,

sent in landfill sites,

or recycled.


Waste production

Landfillsites

A landfill is a site for the disposal of waste materials by burial and is the oldest form of waste treatment. Historically, landfills have been the most common methods of organized waste disposal and remain so in many places around the world. Some landfills are also used for waste management purposes, such as the temporary storage, consolidation and transfer, or processing of waste material (sorting, treatment, or recycling).


Waste production

Incinerators

Incinerators are used for the waste disposal through a process of high-temperature combustion that can recover a little heat and power but also involves toxic emissions.


Waste production

Separate wastecollection

Separate collection of urban waste can be defined as a specific collection system that allows recoverable materials in waste to be separated. The human factor is very important in this new collection model, as the citizen now plays an active rather than a passive role as a processor of materials at source.

Next step is the waste recycling.


Waste production

Recycling

Recycling involves processing used materials into new products in order to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for “conventional” waste disposal, and lower greenhouse gas emissions as compared to virgin production.
