**SYNTHESISE:**

The school waste is made up of food,paper and packaging waste such as sweet wrappers. It may also contain some glass, metals and plastics and that waste increses every year so we need to minimise the waste specially of paper and plastic.

we could reduce plastic by reusing old plastic and make new plastic in that way we could reduce the waste of oil because oil is mainly the most important resource for making plastic; other alternatives of reducing waste is using the rule of the three Rs that is Reduce, Reuse, and Recycle because our school has many waste of paper and plastic if you see the trashes of the school you could see the maiority of rubish is paper and plastic.

An acre of forested land produces form 10 to 15 cords of wood. that means that in one month we use between 1/10 and 2/10 of an acre of forest and in one year we COULD USE UP TO ONE ACRE OF FOESTED LAND just with the paper that is used in the offices and the photocopy centre!!
 * Survey Offices:**We asked secretaries from each office at school how much paper they used in one week. We found out that the administration office is the office that spends the most paper and that the school spends and average of:

May 29/ 2011 By: Maité Nahuel How Much Paper Can You Get From One Tree? How much paper can you get from one tree? It depends. Here’s why. First, unit measurements of pulpwood (for paper and packaging) and sawlogs (for lumber and wood products) are in "cords" and "board feet" respectfully. A pulpwood cord is a stack of logs four feet tall, four feet deep and eight feet long (4 x 4 x 8). All measurements of how much wood fiber is used to produce paper products are in cords or tons. Second, the initial step in preparing logs for pulpmaking is to remove the bark. It is unsuitable for paper production, but is burned by paper firms to produce energy. However, depending on the type of tree, bark can account for 10 to 20 percent of a tree’s volume. Third, different trees yield varying quantities of pulp. It varies, for example, by species (hardwood, softwood and aspen) and subspecies (red pine, jack pine, white pine). Fourth, different paper grades — tissue, computer, magazine, book — require different volumes or densities of pulp. Even within the book grades, there are different weights of paper which require more or less volume of pulp (and wood fiber). Because of these variables, it isn’t possible to determine how many books are made from a single tree. However, it is possible to estimate — in general numbers — how many different products may be produced from a cord of wood. The following list identifies the following yields from a "generic" cord of wood: Additionally, an 1,800 square foot home requires about 10,000 board feet of lumber (roughly equal to about 20 cords of wood). One other interesting rule of thumb is that an acre of forested land may yield an average of 10-15 cords of wood when harvested at maturity — depending not only on the size of the trees, but how productively the land has been managed.

Waste or rubbish is what people throw away because they no longer need it or want it. Almost everything we do creates waste and as a society we are currently producing more waste than ever before. Disposing of waste is difficult and costly. Most of it ends up in holes in the ground (landfill sites) or is burnt in incinerators. Making things from recycled material often uses less energy and causes less pollution. This is important if we want to keep the earth a beautiful place to live in. If we recycle our rubbish, less rubbish will need to be buried in the ground or incinerated. Landfill sites are already becoming full and there are concerns about the impact on people’s health and pollution caused by landfill sites and incinerators. If we make new things by recycling old things, we will save resources. For example, plastic is made from oil. One day we will run out of oil but if we make plastic from old recycled plastic we don’t need to use as much

What are the alternatives to throwing away rubbish? Increasingly, the Government is encouraging people to reduce the amount of rubbish they produce in the first place.To contribute to minimising the waste we produce, government and environmental researchers advise us that, wherever it is practical and beneficial, people should take the following steps:
 * Reduce waste – change manufacturing processes so that less materials are used or change consumer habits so that less wasted material is bought.
 * Reuse – choose goods and products that can be used again.
 * Recycle – make sure that waste is processed and made into another product wherever possible. Composting is also recycling: the nutrients in organic waste are processed and returned to the soil to help more plants to grow. (This is called the triple R)

Waste and schools:
Any building or environment where people live or work will produce a certain amount of waste, and schools are no exception. In general, most school waste is made up of food, paper and packaging waste such as sweet wrappers. It may also contain some glass, metals and plastics.

Minimising waste has a number of benefits for schools. Depending on the waste disposal system in your area, schools can save money on disposal costs by reducing the amount of waste they produce and may also be able to make money by selling materials to be recycled.

is a good candidate for reuse. Are both sides of sheets of paper used before being thrown away? Reducing waste may involve reviewing the types of resources schools buy and considering ways of cutting down.

Prior knowledge:

Waste is made at school because kids don't know in what ways could they help or because they only don't care about it.

Because someone needs to make the work of making concius ohers of the concequences of not reducing.
