D1.4About 60 minutes
Learning goals
  • I can explain the waste hierarchy for electronics: reduce, reuse and repair, refurbish, recycle, dispose.
  • I can identify public agencies, programs and businesses that help with electronics stewardship in Ontario and Canada.
  • I can explain who is responsible for collecting and recycling electronics in Ontario.
  • I can prepare a device safely (backup and data wiping) before it leaves my hands.

Words to know

refurbish
To clean, test, repair, wipe and sometimes upgrade a used device so it can be used again.
recycle
To break a product down so its materials (metals, glass, plastics) can be recovered and used to make new products.
producer responsibility
A policy that makes the companies that make or sell a product responsible for collecting and recycling it at end of life.
RPRA
The Resource Productivity and Recovery Authority, the regulator that oversees Ontario's producer responsibility rules.
data wiping
Securely erasing all personal data from a device, for example with a factory reset, before giving it away.
waste hierarchy
A ranking of waste choices from best (reduce) to worst (dispose).

The drawer of doom

Almost every home has one: a drawer or box of old phones, chargers, earbuds and that laptop that "might be useful someday". Those devices are not doing any harm in the drawer, but they are not doing any good either. The metals inside could be making new devices, and a working laptop could be helping a student who has none.

This lesson is about the agencies, programs and businesses that take old electronics and give them a second life.

The waste hierarchy for electronics. Choose the highest step you can: reducing and reusing save the most resources; disposal (landfill) is the last resort.

Who is responsible in Ontario?

Ontario uses producer responsibility for electronics. Under the Electrical and Electronic Equipment (EEE) Regulation, made under the Resource Recovery and Circular Economy Act, 2016, the companies that make or sell information technology, telecommunications and audio-visual equipment (computers, phones, printers, TVs and more) have been responsible since January 1, 2021 for collecting and recycling those products when people are done with them. Before that, Ontario's program was run by Ontario Electronic Stewardship (OES), which ended on December 31, 2020.

The regulator that oversees these rules is the Resource Productivity and Recovery Authority (RPRA). Producers usually join a producer responsibility organization that runs collection sites for them.

The idea behind producer responsibility is simple: if a company has to pay to recycle its products, it has a reason to design products that are easier to recycle.

Where can things go?

Local community recycling centres and depots. Most Ontario municipalities have a waste depot or special collection days that accept electronics and batteries. Your city or town's waste website lists what it takes.

Retailer take-back. Some electronics retailers accept old devices, chargers and batteries for recycling, sometimes even if you did not buy them there.

Refurbishers. Computers for Schools Plus is a Government of Canada program, running since 1993, that refurbishes donated computers and other devices and gives them to schools, libraries, not-for-profit organizations, Indigenous communities and eligible low-income Canadians. It also gives young people paid internships refurbishing equipment. Private companies also buy, refurbish and resell used computers and phones, often with a warranty.

Printer cartridge recycling programs. Many printer makers run return programs for used ink and toner cartridges, and some stores have drop-off boxes. Some cartridges are refilled and reused.

Battery programs. Call2Recycle runs battery drop-off locations across Canada, often in stores. Remember: lithium-ion batteries must never go in the household garbage or blue box.

A decision tree for an old computer or phone. Every path ends with an agency or action that keeps the device out of the garbage.

Before a device leaves your hands

A computer or phone holds your photos, messages, saved passwords and account sign-ins. Before you donate, sell or recycle it:

  1. Back up anything you want to keep (you learn backup strategies in the unit Computer Environments and Systems).
  2. Sign out of accounts and turn off device-finding features, so the next owner can set it up.
  3. Wipe the device with a factory reset (or ask the refurbisher about their certified data-erasure process).
  4. Remove SIM cards and memory cards.

Reputable refurbishers and recyclers explain how they erase data and how they handle what they can't reuse. A good question to ask: "Where does the material go after you collect it?" Shipping e-waste to countries without safe recycling facilities moves the harm somewhere else; the international Basel Convention, which Canada has joined, controls shipments of hazardous waste between countries.

Worked example

Example 1: Clearing out the drawer

The Tremblay family's drawer holds: (a) a 4-year-old laptop that works, (b) a phone with a cracked screen that turns on, (c) a dead tablet that will not charge, (d) six empty ink cartridges, (e) a bag of old chargers and cables, (f) two swollen phone batteries. Make a plan for each item.

  1. (a) Working laptop: back up, sign out, factory reset, then pass it on or donate it to a refurbisher.
  2. (b) Cracked phone that works: a screen repair may be worth it. If not, a refurbisher or trade-in program can repair and resell it. Wipe it first and remove the SIM card.
  3. (c) Dead tablet: if it cannot be repaired at a fair cost, take it to an approved e-waste drop-off.
  4. (d) Cartridges: return them through the manufacturer's program or a store drop-off box.
  5. (e) Chargers and cables: keep one or two that fit current devices; take the rest to an e-waste drop-off.
  6. (f) Swollen batteries: a swollen battery is damaged and can be a fire hazard. A grown-up should place it in a non-flammable container away from heat and take it promptly to a battery or household hazardous waste drop-off. Never puncture, crush or charge it.

Every item has a destination, and nothing goes in the garbage.

The decision tree as code

The decision tree above is a perfect fit for the selection structures you learned in Programming Basics:

def where_to(works, runs_current_software, repair_is_cheap):
if works and runs_current_software:
return "reuse, pass on, or donate to a refurbisher"
elif works:
return "refurbisher or approved e-waste drop-off"
elif repair_is_cheap:
return "repair it, then reuse"
else:
return "approved e-waste drop-off"
print(where_to(True, True, False))
print(where_to(True, False, False))
print(where_to(False, False, True))
print(where_to(False, False, False))

The decision tree as a Python function with if/elif/else. Output (one line each): reuse, pass on, or donate to a refurbisher / refurbisher or approved e-waste drop-off / repair it, then reuse / approved e-waste drop-off

Just for fun

What did the refurbished laptop say on its first day at its new school?

"Don't worry, I've been through a reboot before."

Hands-on activity

Map your local stewardship options

You need: a computer with internet access and paper or a document.

  1. Find your municipality's waste or recycling web page. List what electronics and batteries it accepts, where, and when.
  2. Find one retailer near you that accepts electronics or batteries for recycling.
  3. Look up the Computers for Schools Plus program and note what it accepts and who it serves.
  4. Find the cartridge return program for the brand of printer in your home (if you have one).
  5. Make a one-page "Where it goes" guide for your household with at least five items and their destinations, plus the four data-safety steps.
  6. With a grown-up, actually take one item from your home to the right place.

What to look for: real local names, addresses or links; correct matching of items to agencies; the data-safety steps included.

For parents and teachers

Big idea: Expectation D1.4 asks students to identify public and private agencies that support environmental stewardship of computers, such as community recycling centres, companies that refurbish computers and printer cartridge recycling programs.

How to help: This lesson is a chance to actually clear out old electronics. Do the mapping activity together and take one load to the right place. Make sure devices are backed up and wiped before they leave home.

Safety: Swollen, damaged or hot batteries are a fire risk. An adult should handle them: keep them away from heat and anything flammable, do not puncture or charge them, and take them promptly to a battery or household hazardous waste drop-off.

Common difficulties:

  • Thinking recycling is always best. Reuse and refurbishing rank higher.
  • Forgetting the data-wiping steps.
  • Confusing refurbishing (the device keeps working) with recycling (the device is broken down for materials).
