Flag hazardous and electronic disposal questions
See this course’s project requirements
A fictional household waste audit separating prevention, reuse, local recycling acceptance and special-disposal questions with checked quantities.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Record a seven-category stream with unit and period.
- Calculate prevention and remaining material without duplicate counts.
- Split suitable cardboard reuse from remaining cardboard.
- Apply the supplied local guide and balance every route.
- Write special-provider questions without handling items.
- Compare and revise the complete plan with honest status labels.
Review and revise
Use these criteria to check your work and choose what to improve.
- Method: applies the course-specific rules to the supplied cases with visible intermediate work.
- Accuracy: results agree with the stated facts, units, boundaries and independent checks.
- Reasoning: explains why the result follows and identifies a limitation or unresolved question.
- Transfer: completes changed cases and revises the final project when a relevant assumption changes.

The idea in everyday life
Fictional one-week household stream, already recorded by a responsible adult: paper 3 kg; clean cardboard 2 kg; empty accepted-type bottles 1 kg; plastic film 1 kg; food scraps 2 kg; spent batteries 0.2 kg; old electronics 0.8 kg. Learners use this record without handling or weighing materials. The supplied electronics include a lithium-ion battery. Town R’s exercise guide excludes batteries and electronics from curbside recycling; no actual collection provider or receipt is supplied.
Some household materials require special instructions because of toxicity, reactivity, fire risk or other hazards. Do not mix unknown products, pour them into drains or assume ordinary trash/curbside recycling is appropriate. EPA advises keeping lithium-ion batteries and devices containing them out of household garbage and recycling bins. Ask the relevant local hazardous-waste or electronics provider about accepted items and arrangements; do not disassemble devices here.

1. 1. Flag
Mark the two rows needing special-route information.
You should see: 0.2 kg batteries and 0.8 kg electronics.
2. 2. Quantify
Total the flagged material.
You should see: 1 kg special-route questions.
3. 3. Ask
Draft provider questions rather than guessing a bin.
You should see: Does the provider accept the stated battery/device types, and what arrangements does it require?
4. 4. Bound
Add handling and record limits.
You should see: No mixing, dismantling, battery removal, unknown-product handling or completed-disposal claim.
What to finish
A battery/electronics question card with checked mass and explicit handling limits.
Watch for this
The learner can complete a question card from supplied facts. Physical handling, mixing and disassembly are outside this safe planning task.
How can I tell I understand it?
Reject a changed inappropriate lithium-ion route while preserving the need for local instructions.
