The school "Arboleja" of Murcia has been proposed during this school year to reduce the consumption of paper in the packaging of snacks
One of the most difficult challenges that society is to achieve socio-economic development compatible with the environment it faces.
All consumers can purchase energetically efficient, reusable and made from recycled materials etc products.
With the "Green Schools" program of the Department of Environment, directed Adela Martinez-Cache, is to instill in students and the entire school community the idea that we are all consumers and that consumption is necessary, but we must keep the natural resources, save energy and avoid waste.
Therefore, the Department has launched the "0 aluminum" and many schools in the municipality of Murcia are getting it.
The main domestic use of aluminum is food in schools and the foil wrapper is king of sandwiches every day.
But how many square inches of paper we use every day, and every month and every year, How heavy aluminum foil you use after one year of wrapping the sandwich-We live immersed in the culture of "disposable" but the alternative to the use of aluminum to wrap the sandwiches already exists wrappings reusable.
The main source of aluminum is bauxite, abundant mineral in the subtropical belt around the planet, but the big aluminum industry is in developing countries where environmental standards are virtually nonexistent and therefore production costs minors.
The deposits are in high natural ecosystems, with high biodiversity tropical forests.
The main waste generated per kilo paper manufactured aluminum are:
- 0.6 kg of heavy metal clays.
Contamination of soil and water
- 0.3 kg of sulfur oxides.
Cause of acid rain
It is evident, therefore, that the use of aluminum foil to wrap sandwiches has a very high environmental cost, considering that is a material that is used once and then discarded.
Therefore, the school "The Arboleja" of Murcia has been proposed during this school year to reduce the consumption of aluminum foil wrap sandwiches.
To meet this goal in the early going, the students received a briefing, and during that time have been gradually leaving to bring aluminum.
Yes, that has been collected, they have always taken the yellow container.
To do this, in every classroom, have enabled boxes, and each week the Green Patrol, formed a group of students, have emptied in the yellow container.
At the end of the course they have calculated the amount of paper you have left and bring environmental benefits have been achieved with this action.
And these are the results:
During the 2nd and 3rd quarter of the year: 12.130 grams was the amount of aluminum that have stopped carrying colleges and 3,583 grams is azubre oxide that has stopped broadcasting.
30% to 50% of Spanish forest defoliation present problems due to acid rain, a type of air pollution due to the combination of nitrogen and sulfur oxides from human activities, the water vapor in the atmosphere, which subsequently precipitated by acidifying the soil ground.
