Make the recycling collectionTry to make the recycling collection both at home and at school

Use your bikeDont use private cars if you do short journeys

Use public transportsDont pollute the air and use the public transport to move

Use glasses and platesDont use plastic plates and bags

Use biodegradable bagsWhen you go the grocery store use biodegradable bags

Use eco-friendly nappiesTraditional nappiess degradation requires 500 years

Use low consumption light bulbsthey consume 5 times less and last 10 times longer

Use rechargeable batteriesBatteries can be recharged up to 500 times

What do you prefer?

Glossary Classe IIIB ChlorofluorocarbonsChemical hazardous compounds widely used as refrigerants, cleaning solvents and aerosol propellants

EcologyThe study of the relationship between plants, animals, people and their environment

Acid rainIt is caused by acid discharged into the atmosphere from factories

Green peace Active environmentalist group

Greenhouse

Ozone

Thin layer of triatomic oxygen that absorbs the Suns ultraviolet radiation

PollutionThe contamination of water, air and atmosphere by means of poisonous chemicals and other substances

Biodegradable

What decomposes without any special treatment and is thrown away without causing pollution

Overpopulation Excessive population of an area causing depletion of natural resources and environmental deterioration.

Melting of ice caps When a high latitude region that is covered with ice becomes smaller and slowly disappears

Global warming The rise in the average temperature of the earths atmosphere and of oceans

Did you know ... Classe IIIA Burning plastic releases dioxins and nanoparticles, highly polluting substances for man

The solution is one:

Pretend that plastic bags do not exist: If you throw the plastic in a landfill it takes more than 1000 years before it decomposes

Consume local products: the transport of goods consumes oil and increases the greenhouse effect.

Get the sun. How? With the solar pannels.

Change the car: choose natural gas or gpl. And, above all, use it as little as possible

To store food use glass and aluminum

Use energy saving light bulbs: they consume 5 times less and last 10 times longer.

Disposable? No, thanks. Use rechargeable batteries: batteries can be recharged up to 500 times.

Recycling is the smartest and the most important contribution you can give to the environment

together we make the differenceRecycling processes a set of strategies to recover materials from waste to be re-used

71Waste Management a big problem in a modern society but... before

A look into the past Classe IIIB Something about its historyThroughout most of history, the amount of waste generated by humans was insignificantCommon waste produced during pre- modern times was mainly ashes and human biodegradable waste and these were released back into the ground locally, with minimum environmental impact

Tools made out of wood or metal were generally reused or passed down through the generations

However, some civilizations do seem to have been more profligate in their waste outputMaya, for instance, used to have a fixed monthly ritual, in which the people of the village would gather together and burn their rubbish in large dumps

An example of Mayas dump

The modern era: time of changesThe modern era represents a time of changes:following the onset of industrialization and the sustained urban growth of large population centres, the build up of waste in the cities caused a rapid deterioration of sanitation and the general quality of urban life.

what does waste management imply in our society?Waste management consists of different stages :

collection of rubbish

transport

disposal

managing

monitoring

recycling

Waste management usually relates to the materials produced by the human activities and the process is generally undertaken to reduce their effect on health, the environment and the quality of urban life.

There are different kinds of waste materials: solid, liquid, gaseous and radioactive materials.

Waste management practices arent equal all over the world, in fact they can differ for developed and developing countries, for urban and rural areas, and for residential and industrial producers.

Management of non-hazardous waste residential and institutional waste in metropolitan areas is usually the responsibility of local government authorities, while commercial and industrial waste management is usually the responsibility of local, national or international authorities.
