2. 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

3. To prevent an excess of pollution we should:
-Avoid disposable products
-Buy products with little packaging
-Drink filtered water from the tap
-Reuse and recycle

4. Waste can be
burned in incinerators,
sent in landfill sites,
or recycled.

5. Landfill sites
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).

6. 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.

7. Separate waste collection
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.

8. 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.
