How To Manage Our School Waste ?

     When looking at waste, we need to think about the materials we use, what we throw away and where.
 The first step in managing waste is to minimise the amount of waste produced. The second is to look at ways to reuse materials and the third and last resort is to recycle as much as possible.
A waste management plan in your school will reduce litter, waste and associated disposal costs in your school while creating worthwhile learning opportunities for students.
For the best results, get everyone in your school community committed and involved - the principal, teachers, students, parents and anyone else interested.

     Schools use a lot of different products and materials everyday. They also generate waste. Schools can successfully recycle materials and some of their waste. Different practices in schools can reduce the amount of materials used and waste generated, as well as increase the number of material being recycled.

     The following are the steps to manage waste :
1. General Waste
General waste is made up of all materials that cannot be recycled through other waste streams. It is collected and transported to a landfill site where it is buried. Some landfill sites extract methane from decomposing waste for their energy needs. Paper contaminated with food waste needs to go into general waste.

2. Paper Recycling
Paper and cardboard products are the most common items a school recycles. Secure documents are stored in locked bins before being shredded and joining other paper fibres.

3. Co-Mingled Recycling
Co-Mingled recycling collects aluminium cans, glass bottles, plastic bottles, steel cans,Tetrapaks and cartons for recycling.

4. E-Waste
Computers, phones, toner cartridges, printers and batteries all contain resources that can be recycled.

5. Organic Waste
Schools can manage organic waste on site. Composting systems and worm farms manage fruit and vegetable waste, and mulching recycles green waste. Both processes produce nutrient rich materials for use on gardens.
