Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating the ability to correctly classify waste streams according to the waste hierarchy, identifying specific opportunities for prevention, reuse, recycling, recovery, and disposal.
- Credit should be given for conducting a thorough cost-benefit analysis that incorporates environmental impacts (e.g., carbon footprint, resource depletion) alongside financial metrics.
- Evidence must show the ability to evaluate the sustainability of a resource by considering its full lifecycle: extraction, production, use, and end-of-life management.
Assessment Guidance
Guidance for achieving higher grades
- 💡When evaluating a resource, always reference the waste hierarchy and provide a justification for the chosen option based on sustainability principles.
- 💡Use specific data and case studies to support your evaluation; generic statements lose marks in assessments.
- 💡Remember to consider social sustainability, such as job creation or community impacts, not just environmental and economic factors.
- 💡Always quote specific legislation and regulations, such as the Environmental Protection Act 1990 or the Waste (England and Wales) Regulations 2011, to demonstrate depth of knowledge.
- 💡Use the 'STAR' method (Situation, Task, Action, Result) when answering questions about supervisory scenarios to structure your response clearly.
- 💡In calculations, show all your working and include units (e.g., tonnes, %) to ensure you gain method marks even if the final answer is wrong.
Common Mistakes
Common errors to avoid in your coursework
- Confusing 'recycling' with 'downcycling', failing to recognize that some materials degrade in quality when recycled and may not be infinitely recyclable.
- Overlooking the energy and water consumption in recycling processes, thus incorrectly assuming that all recycling is always sustainable.
- Ignoring local market conditions for recycled materials, leading to stockpiling or contamination issues that undermine sustainability.
- Misconception: The waste hierarchy is just a guideline, not a legal requirement. Correction: The Waste (England and Wales) Regulations 2011 make it a legal duty to apply the hierarchy as a priority order when managing waste.
- Misconception: A waste transfer note (WTN) is the same as a waste permit. Correction: A WTN is a document that must accompany waste when it is transferred, detailing its nature and quantity, while a permit is a legal authorisation to operate a waste facility.
- Misconception: Once waste is sent for recycling, the producer has no further responsibility. Correction: The Duty of Care extends until the waste is fully recovered or disposed of, so producers must ensure their waste is handled by authorised carriers and facilities.

Detailed solution breakdown for typical exam problems
Question: A waste transfer station receives 500 tonnes of mixed waste per week. After sorting, 200 tonnes are sent for recycling, 150 tonnes for energy recovery, 50 tonnes for composting, and the rest to landfill. Calculate the percentage of waste diverted from landfill and the amount sent to landfill.
- 1.Step 1: Identify the total waste and the amounts diverted: recycling (200 t), energy recovery (150 t), composting (50 t). Total diverted = 200 + 150 + 50 = 400 tonnes.
- 2.Step 2: Calculate the amount to landfill: Total waste - diverted = 500 - 400 = 100 tonnes.
- 3.Step 3: Calculate the percentage diverted: (400 / 500) * 100 = 80%.
Question: A waste supervisor must conduct a risk assessment for a new baler machine. Identify three hazards and the corresponding control measures, and explain the legal requirement for risk assessment under the Management of Health and Safety at Work Regulations 1999.
- 1.Step 1: Identify hazards: moving parts (crushing), noise (hearing damage), manual handling (musculoskeletal injury).
- 2.Step 2: For each hazard, state a control measure: guarding and interlocks for moving parts, hearing protection zones and PPE, mechanical aids and training for manual handling.
- 3.Step 3: Explain the legal duty: The Management of Health and Safety at Work Regulations 1999 require employers to carry out suitable and sufficient risk assessments to protect employees and others from harm. The supervisor must ensure these are reviewed regularly.
