I assume you are asking about what happens, or what should happen, with the trash a typical school produces.
For most schools in the US, the largest portion of waste produced is paper. Paper can and should be recycled; most communities have a way to send materials like paper to a facility where it is shredded and turned into either new paper or an alternative product like building insulation. However , in order for this to happen, the whole school must commit to a program to make it work. The paper must be separated from the other trash, kept dry, and taken to the recycling depot. In the schools where I have worked, students have taken on the task of separation, and the custodial staff takes the paper to the recycling location.
Plastic such as water bottles and food containers can be recycled in much the same way. Recycling plastic is important, because it, unlike paper, will not break down in a landfill. The different types of plastic, which can be identified by the number inside the triangle symbol stamped on them (usually on the bottom), are recycled into different things. Some are melted and recast, some turned into a lumber-like substance, and some are shredded and used as insulation in winter clothing. One type can even be shredded and spun into yarn that is knit into clothing!
Food waste from the cafeteria can be a messy issue. In some schools, the school has partnered with a farmer who removes the waste food daily and uses it as animal feed for chickens or pigs. Other schools compost their waste. In either case, students need to help by not throwing non-food items in with the food.
There will always be a few things that are not practical to recycle or compost. Pencil waste - the shaving from the sharpeners - is one of them. It should not be composted because the paint on the outside of the pencil may contain metals. So this waste should go to a landfill. However schools can greatly reduce their contribution to landfills by recycling or composting what they can.
