{{BR}}
= Introduction =

Every day, people use food, paper, packaging, clothes, electronics, and many other things. When an item is no longer wanted, it can become '''waste'''. But not everything we call waste has to be thrown away. You can often prevent waste, use an item again, repair it, recycle its material, or compost suitable food and yard scraps.

[[File:Recycling symbol.svg|500px|frameless|center]]

This course will help you understand [[English:Waste|waste]], [[English:Waste hierarchy|the waste hierarchy]], [[English:Reuse|reuse]], [[English:Repair|repair]], [[English:Recycling|recycling]], and [[English:Composting|composting]]. You will also learn why local rules matter and how you can reduce waste at home and at school.

{{BR}}
== Learning Goals ==

By the end of the course, you should be able to explain the difference between reducing, reusing, repairing, recycling, composting, and disposal. You should also be able to make safer sorting choices, investigate your local recycling rules, and design a practical waste-reduction idea for your school or home.

{{BR}}
== What Is Waste? ==

Waste is material that someone decides to discard. It can include food scraps, paper, cans, bottles, broken objects, old clothes, and many other things. Some waste goes to a [[English:Landfill|landfill]], where it is placed for long-term disposal. Other materials may be collected for recycling or composting.

[[File:Waste disposal-landfill.jpg|500px|frameless|center]]

Throwing something away does not make it disappear. Waste still has to be collected, transported, sorted, treated, recycled, composted, burned, or buried. That is why it is useful to think about waste '''before''' you create it.

{{BR}}
== Why Reduce Waste? ==

Making a new product usually requires raw materials, energy, water, transportation, and work. If you avoid an unnecessary product or keep an item in use for longer, you can reduce the need for new materials and reduce the amount of waste that must be managed.

Waste reduction can be simple. You might carry a refillable water bottle, pack food in reusable containers, print only when needed, borrow an item you will use once, or choose a durable product that can be repaired.

{{BR}}
== The Waste Hierarchy: Think Before You Throw ==

A [[English:Waste hierarchy|waste hierarchy]] ranks choices from more preferred to less preferred. A simple version for everyday life is:

# [[English:Waste minimisation|Reduce]]: Prevent waste before it is created.
# [[English:Reuse|Reuse]]: Use an item again for the same or a new purpose.
# [[English:Repair|Repair]]: Fix an item so it can stay in use.
# [[English:Recycling|Recycle]]: Process accepted used materials into materials for new products.
# [[English:Composting|Compost]]: Let suitable organic materials break down in a managed system.
# [[English:Landfill|Dispose]]: Use disposal when the better options are not possible.

The exact order can vary for special materials, but the main idea is clear: '''preventing waste is usually better than dealing with waste after it has already been created'''.

{{BR}}
=== Reduce ===

To reduce means to create less waste in the first place. You can ask yourself: Do I need this? Can I choose less packaging? Can I bring something reusable instead?

[[File:Reusable Bag.jpg|500px|frameless|center]]

A reusable bag can replace many single-use bags over time when you remember to bring it and keep using it.

{{BR}}
=== Reuse and Repair ===

Reuse means using an item again instead of throwing it away. A glass jar can hold craft supplies. A book can be passed to another reader. Clothes can be handed down, donated, swapped, or used again in another way.

Repair means fixing something so it can keep doing its job. Sewing on a button, patching a small tear, or replacing a simple broken part can extend the life of an item. For tools, electronics, or anything sharp or electrical, ask a trained adult for help.

{{#ev:youtube|https://www.youtube.com/watch?v=-Ad0vzBxBzU|500|center}}

This SciShow Kids video shows a hands-on example of turning old crayons into something useful again. As you watch, notice how keeping material in use can reduce the need to throw it away.

{{BR}}
=== Recycle ===

Recycling means collecting and processing materials that would otherwise be thrown away and turning them into material for new products. Commonly recycled materials can include paper, cardboard, metal cans, glass containers, and some plastics, but '''the accepted items depend on your local program'''.

[[File:Recycling bins.JPG|500px|frameless|center]]

A recycling symbol does not automatically mean that every local program accepts the item. Always check the instructions on your school, town, city, or waste-service website.

{{BR}}
== Sorting Waste Correctly ==

Good sorting matters because the wrong item can cause '''contamination'''. Contamination happens when unwanted materials are mixed with the materials a recycling or composting program is trying to collect.

[[File:Sorted waste containers in Haljas street.JPG|500px|frameless|center]]

Before you sort an item, ask these questions:

# Is this item accepted by my local program?
# Does it need to be empty, scraped, or rinsed?
# Does it belong in a special collection instead of a normal bin?
# Is it sharp, broken, leaking, or unsafe to touch?

Do not handle broken glass, sharp metal, unknown liquids, chemicals, or damaged batteries by yourself. Ask an adult and follow local instructions. Batteries and electronics often need special collection and should not simply be placed in an ordinary recycling bin.

{{BR}}
== What Happens During Recycling? ==

After recyclables are collected, they may travel to a sorting facility. Machines and workers separate materials into groups. Different materials then follow different processes. Paper can be pulped into fibers, metals can be melted, glass can be crushed and remade, and some plastics can be sorted, cleaned, and processed into material for new products.

{{#ev:youtube|https://www.youtube.com/watch?v=VlRVPum9cp4|500|center}}

While watching this SciShow Kids video, look for the main steps between putting an accepted item in a recycling bin and making a new product. Remember that recycling is useful, but it does not replace reducing and reusing.

{{BR}}
== Composting Food and Yard Scraps ==

Composting is a managed process in which microorganisms break down organic materials with oxygen. Suitable materials can include some fruit and vegetable scraps, leaves, and other plant matter. The finished compost can be added to soil.

[[File:Nothing will be wasted! Kitchen scraps for compost!.jpg|500px|frameless|center]]

A compost system needs the right mix of materials, moisture, and air. What belongs in a compost bin depends on the type of system, so follow the rules for your home, school, or community program.

{{#ev:youtube|https://www.youtube.com/watch?v=26IO95Xt5WU|500|center}}

This SciShow Kids field trip shows how food scraps can become compost. As you watch, identify what changes and what helpers, such as microorganisms, make decomposition possible.

{{BR}}
== Smart Choices at School and Home ==

You do not need to be perfect to make a difference. Start with one repeated habit. You could bring a refillable bottle, use both sides of paper, take only the food you expect to eat, share or donate usable items, repair something simple, or sort accepted recyclables carefully.

A useful decision question is: '''Can I avoid this waste, use the item again, or repair it before I recycle or dispose of it?''' This question helps you move higher in the waste hierarchy.

{{BR}}
== A Simple Class Waste Audit ==

A waste audit is a careful study of what a group throws away. With a teacher, you can collect safe information without touching dangerous waste. For example, you can count or weigh sealed categories such as paper, packaging, food scraps, and reusable items. Then you can ask which category is largest and what action would reduce it.

A good audit does more than count rubbish. It helps you make a plan, test an idea, and compare results later. You might discover that your class needs clearer labels, fewer disposable supplies, better food planning, or a reuse box for paper and craft materials.
