Characterise the Waste Stream and Regulatory Context
2–3 weeks (3–4 hrs/week)
Select a real or realistic waste management design problem: municipal solid waste collection and treatment, industrial process waste, construction and demolition waste, electronic waste, or healthcare waste. Characterise the waste stream: estimated annual volume or mass, composition (by fraction: food, paper, plastics, metals, hazardous, inert, or equivalent for industrial waste), key physical properties (density, moisture content, calorific value if relevant), and any hazardous components. Document the applicable regulatory framework: waste hierarchy (EU Waste Framework Directive, UK Environmental Permitting Regulations, or equivalent), classified waste codes (EWC/LER/SIC codes), and the disposal restrictions applying to the waste type.
Proof required
Submit your waste characterisation document (≥600 words): waste stream description with estimated volume or mass, composition table by fraction (% by weight or volume), key properties cited from data sources, applicable waste codes, and the regulatory hierarchy requirements for this waste type.
What gets checked
- Waste composition is given by fraction with percentages — not described qualitatively as 'mixed waste'
- Applicable waste codes are cited (EWC, UK waste classification, or equivalent regulatory code) — not just described as 'hazardous' or 'non-hazardous'
- Regulatory hierarchy requirements are stated for this specific waste type — not generic statements about the waste hierarchy
Common mistakes
- Waste characterisation without data sources — waste composition fractions must be cited from a real dataset, regulatory publication, or published case study; assumed fractions are not acceptable
- Regulatory framework described generically without applying it to the specific waste stream — the waste hierarchy applies differently to hazardous and non-hazardous waste; the waste codes determine what disposal routes are legally available

What a verifier looks for
- Confirm waste composition gives fractions by percentage — flag qualitative descriptions without data.
- Confirm applicable waste codes are cited — flag unclassified 'hazardous' or 'non-hazardous' statements.
- Confirm regulatory requirements are applied to the specific waste stream, not stated generically.
Evaluate Treatment Options and Design the Waste Management System
3–4 weeks (4–5 hrs/week)
Evaluate ≥3 treatment or disposal options appropriate for the waste stream characterised in M1, applying the waste hierarchy (prevention → preparation for re-use → recycling → recovery → disposal as the preference order). Apply a technology selection matrix scoring each option on: alignment with waste hierarchy level, technical feasibility for the characterised waste, environmental impact, cost (capital and operating), and regulatory permissibility. Select the preferred option and provide a basic system design: waste collection or pre-treatment steps, the primary treatment or disposal route, and residual management. Quantify the waste diverted from landfill (kg/year or %).
Proof required
Submit your technology selection matrix (≥3 options, ≥4 scoring criteria) and system design description (collection/pre-treatment → primary treatment/disposal route → residual management, with estimated waste diverted from landfill as kg/year or %).
What gets checked
- Technology selection matrix compares ≥3 options on ≥4 criteria — not a narrative preference
- Waste hierarchy level is one of the comparison criteria — options higher in the hierarchy must justify displacement by lower-hierarchy options
- Waste diverted from landfill is quantified — not stated as 'most waste will be recycled'
Common mistakes
- Technology selection without reference to the waste hierarchy — the hierarchy is a legal requirement in most jurisdictions; a waste management design that prefers incineration over recycling without justification does not comply with regulatory requirements
- Diverted waste fraction not quantified — 'significant recycling' is not a design output; the design must produce a waste diversion estimate in mass or percentage

What a verifier looks for
- Confirm technology selection matrix compares ≥3 options on ≥4 criteria including waste hierarchy level.
- Confirm waste diversion from landfill is quantified — flag qualitative-only statements.
- Confirm waste hierarchy is applied as a criterion — flag designs that prefer lower hierarchy options without justification.
Write the Waste Management Design Report
2–3 weeks (2–3 hrs/week)
Write a complete waste management design report (2,000–3,000 words plus tables) covering: waste stream characterisation, regulatory requirements and waste codes, technology evaluation and selected system design, estimated waste diversion from landfill and environmental benefits (CO2e avoided, landfill space saved), permitting requirements for the selected treatment route, and monitoring and reporting obligations. Have the report reviewed by an environmental engineer, waste management professional, or sustainability engineer and respond to Q&A on the technology selection and regulatory compliance.
Proof required
Submit your waste management design report (2,000–3,000 words plus tables) and review record: reviewer name, role, ≥3 challenge questions about technology selection or regulatory compliance, and your responses.
What gets checked
- Environmental benefits are quantified — CO2e avoided from landfill diversion, landfill volume displaced, or equivalent metric
- Permitting requirements for the selected treatment route are identified — what permit, from which authority, and what the key conditions are
- Reviewer has waste management, environmental engineering, or sustainability experience and challenged the technology selection or regulatory compliance
Common mistakes
- Environmental benefits stated without quantification — 'the design reduces environmental impact' is not a benefit; '2,400 tCO2e avoided per year based on DEFRA conversion factors for landfill methane' is
- Permitting requirements omitted — a waste management design is not actionable without identifying the regulatory permit needed; no permit pathway = no implementation

What a verifier looks for
- Engineering Design Triad check: M1–M3 together produce a design artifact (waste management system design with selected treatment route), an analysis artifact (technology selection matrix + waste diversion and CO2e quantification), and a documentation artifact (waste management design report + review record) — confirm all three types are present.
- Confirm environmental benefits are quantified with units (tCO2e, tonnes diverted, volume displaced).
- Confirm permitting requirements are identified — flag designs with no permit pathway.
- Confirm reviewer has waste management or environmental engineering experience and challenged the technology selection or regulatory compliance.
- The Proof Accessibility Rule applies — EEA free waste data, UK Environment Agency free guidance, WRAP free resources, EPA free data, DEFRA free conversion factors, and draw.io (free) are all accessible without commercial licence.
