Waste management and remediation

Waste comes as household, business, construction and hazardous streams. Remediation cleans contaminated land or water.

• Know the hierarchy: reduce, reuse, recycle, recover, dispose.
• Measure a stream: tonnes, composition, sources.
• Choose materials that have a market where you are; a material nobody buys is a cost, not a product.
• Pick a niche: construction waste, organics, e-waste, site clean-up.
• Sort a sample into wood, metal, drywall, plastics and organics, and weigh each.
• Find who buys each recovered material and what contamination limit they set.
• Estimate haul distance, because long distances can erase the value of a material.

Activity. Sample and weigh a waste stream.

Standard to meet. Build the composition table.

Waste is heavily regulated.

• Provincial approvals are required for waste handling, transport and processing.
• Hazardous waste needs manifests and licensed carriers.
• Contaminated sites follow assessment and clean-up standards with qualified professionals.
• Worker safety training and protective gear are mandatory.
• Learn that the definition of hazardous waste varies by province; check the provincial rule.
• Keep a training record for each worker, with date and topic.
• For contaminated sites, require an assessment report from a qualified professional before work starts.

Activity. Build a rules table.

Standard to meet. Cite a source and a date for every row.

Flow design decides cost.

• Route collection; sort at source if possible.
• Design the sorting line and storage.
• Test contamination levels by customer to see who needs help sorting.
• Record every load with date, source, weight and condition.
• Place labelled bins where waste is made, using pictures as well as words.
• Size storage for a week of peak flow and keep fire separation between piles.
• Weigh the contaminants in ten sample loads.

Activity. Design a sorting flow.

Standard to meet. Draw a flow diagram with limits.

Gate fees plus material sales.

• List costs: collection, labour, equipment and disposal.
• Add revenue per tonne from collection fees, gate fees and material sales.
• Work out margin per tonne as price minus cost.
• Work out break-even tonnes as fixed cost divided by margin per tonne.
• Work out cost per tonne from trucks, fuel, labour and tipping fees divided by tonnes handled.
• Check how much revenue depends on recovered-material prices, since those can fall.
• Test a price fall, since recovered-material prices change.

Activity. Build a cost sheet with price fall.

Standard to meet. Show the cases.

Keep records.

• Weigh loads in and recovered material out so the tonnes balance.
• Keep protective gear checked and in good condition for every worker.
• Keep spill kits stocked and run spill and fire drills.
• Report the diversion rate to management each month.
• Weigh every load and keep a scale ticket with date, vehicle and weight.
• Hold a daily briefing on hazards, protective gear, who is on site and exits.
• Compute diversion rate as diverted tonnes divided by total tonnes.

Activity. Keep a 4-week operations log.

Standard to meet. Compute rates.

Win with compliance and price.

• Look for municipal and commercial tenders that match your permits.
• Collect references from past clients.
• Offer certified reporting of tonnes diverted.
• Track bids, shortlists and wins.
• Read each tender for scoring weights, mandatory forms and reporting duties.
• Prepare references that show outcomes such as tonnes diverted.
• Price with a margin and a fuel-escalation clause.

Activity. Prepare a tender response.

Standard to meet. Complete the response.

Harm lasts.

• Expect odour, noise and traffic complaints and plan controls for each.
• Plan for fire at storage areas.
• Understand financial assurance: security a regulator may require to cover clean-up if you fail.
• Keep insurance current for pollution, property and liability.
• Keep a complaint log with date, type, response and closing date.
• Reduce fire risk with separate piles, temperature checks, extinguishers and fire-truck access.
• Check that insurance covers pollution and check the provincial financial-assurance rule.

Activity. Write a risk register.

Standard to meet. Name an owner for each item.

Prove one stream.

• Run the pilot for 60 days.
• Measure diversion rate and cost per tonne.
• Stop rule: contamination over 15% means fix.
• Plan to scale only if the stream passes the stop rule.
• Choose one stream, such as clean wood from three sites.
• Weigh in, sort and weigh out, and keep the tickets.
• Report results to the buyer and ask what they want improved.

Activity. Run pilot review.

Standard to meet. Review has decision.

L1: Sustainability aware learner. You can define: name the main terms, people and rules of waste management and remediation. Focus module: Understand waste streams and remediation (Understand, 6 h). Waste comes as household, business, construction and hazardous streams. Remediation cleans contaminated land or water. Key points: Know the hierarchy: reduce, reuse, recycle, recover, dispose. Measure a stream: tonnes, composition, sources. Choose materials that have a market where you are; a material nobody buys is a cost, not a product. Pick a niche: construction waste, organics, e-waste, site clean-up. Sort a sample into wood, metal, drywall, plastics and organics, and weigh each. Find who buys each recovered material and what contamination limit they set. Estimate haul distance, because long distances can erase the value of a material.

Speaker notes. Teach: open with the worked example. A building site produces 60 t of waste; sorting could divert 70%, which is 42 t, leaving 18 t for landfill. If disposal costs 100 per tonne, diverting 42 t avoids 4,200, before the cost of sorting. Then set the activity: Sample and weigh a waste stream. Mark against the standard: Build the composition table. Check at this level: List the waste hierarchy. Model answer: Reduce, reuse, recycle, recover, dispose. Level note: Start here if new. Evidence: a one-page glossary and a visit or interview note.

L2: Field or plant assistant. You can describe: explain how waste management and remediation works from first contact to result. Focus module: Know environmental and handling rules (Apply, 6 h). Waste is heavily regulated. Key points: Provincial approvals are required for waste handling, transport and processing. Hazardous waste needs manifests and licensed carriers. Contaminated sites follow assessment and clean-up standards with qualified professionals. Worker safety training and protective gear are mandatory. Learn that the definition of hazardous waste varies by province; check the provincial rule. Keep a training record for each worker, with date and topic. For contaminated sites, require an assessment report from a qualified professional before work starts.

Speaker notes. Teach: open with the worked example. Row: 'Haul hazardous waste | provincial environment ministry | licence and manifest | each load | manifest copies'. A second row: 'Operate a transfer site | provincial environment ministry | approval | before opening | approval letter'. Date each source. Then set the activity: Build a rules table. Mark against the standard: Cite a source and a date for every row. Check at this level: Who approves waste operations? Model answer: The provincial environment authority, under the provincial rule. Level note: Evidence: a flow chart and a two-minute spoken explanation.

L3: Technician. You can apply: carry out a routine task in waste management and remediation to a written standard. Focus module: Plan collection, sorting and treatment (Apply, 10 h). Flow design decides cost. Key points: Route collection; sort at source if possible. Design the sorting line and storage. Test contamination levels by customer to see who needs help sorting. Record every load with date, source, weight and condition. Place labelled bins where waste is made, using pictures as well as words. Size storage for a week of peak flow and keep fire separation between piles. Weigh the contaminants in ten sample loads.

Speaker notes. Teach: open with the worked example. Contamination is 18% in mixed loads and 6% with source sorting. In a 50 t load that is 9 t versus 3 t, so source sorting removes 6 t of contamination. Then set the activity: Design a sorting flow. Mark against the standard: Draw a flow diagram with limits. Check at this level: Why sort at source? Model answer: Lower contamination. Level note: Evidence: a supervised task record that meets the standard once.

L4: Specialist. You can analyse: diagnose why a waste management and remediation result missed its target and fix it. Focus module: Cost per tonne and revenue (Evaluate, 8 h). Gate fees plus material sales. Key points: List costs: collection, labour, equipment and disposal. Add revenue per tonne from collection fees, gate fees and material sales. Work out margin per tonne as price minus cost. Work out break-even tonnes as fixed cost divided by margin per tonne. Work out cost per tonne from trucks, fuel, labour and tipping fees divided by tonnes handled. Check how much revenue depends on recovered-material prices, since those can fall. Test a price fall, since recovered-material prices change.

Speaker notes. Teach: open with the worked example. Price 180 per tonne; cost 120; margin 60; fixed cost 540,000 a year gives 540,000 / 60 = 9,000 t. If the price falls 10% to 162, margin is 42 and break-even rises to 540,000 / 42 = about 12,857 t. Teaching figures in CAD. Then set the activity: Build a cost sheet with price fall. Mark against the standard: Show the cases. Check at this level: What is a gate fee? Model answer: Fee for accepting waste. Level note: Evidence: a fault or gap analysis with a fix and a repeat test. This course targets this level.

L5: Senior specialist or lead. You can evaluate: judge options for waste management and remediation against cost, risk and quality. Focus module: Win contracts and partners (Create, 6 h). Win with compliance and price. Key points: Look for municipal and commercial tenders that match your permits. Collect references from past clients. Offer certified reporting of tonnes diverted. Track bids, shortlists and wins. Read each tender for scoring weights, mandatory forms and reporting duties. Prepare references that show outcomes such as tonnes diverted. Price with a margin and a fuel-escalation clause.

Speaker notes. Teach: open with the worked example. Funnel: 15 bids, 4 shortlists, 2 wins. Shortlist rate is 4 / 15 = 27%, win rate from shortlist is 2 / 4 = 50%, and overall 2 / 15 = 13%. Then set the activity: Prepare a tender response. Mark against the standard: Complete the response. Check at this level (this question is covered in module 5: Operate safely and measure): What is diversion rate? Model answer: Share kept from landfill. Level note: Evidence: an options paper with numbers and a recommendation defended to a panel.

L6: Programme manager. You can create: design and pilot a new offer or process in waste management and remediation. Focus module: Manage contamination, community and liability risk (Evaluate, 6 h). Harm lasts. Key points: Expect odour, noise and traffic complaints and plan controls for each. Plan for fire at storage areas. Understand financial assurance: security a regulator may require to cover clean-up if you fail. Keep insurance current for pollution, property and liability. Keep a complaint log with date, type, response and closing date. Reduce fire risk with separate piles, temperature checks, extinguishers and fire-truck access. Check that insurance covers pollution and check the provincial financial-assurance rule.

Speaker notes. Teach: open with the worked example. Risk: 'Storage fire | 2 x 5 | spacing, detection | site lead | monthly'. The score is 2 x 5 = 10; low likelihood but severe impact, so controls are checked monthly. Then set the activity: Write a risk register. Mark against the standard: Name an owner for each item. Check at this level: Why financial assurance? Model answer: Clean-up cost if the operator fails. Level note: Evidence: a pilot with measured results over at least 30 days.

L7: Director or founder. You can lead: run a team or business in waste management and remediation and develop others. Focus module: Pilot a stream (Create, 8 h). Prove one stream. Key points: Run the pilot for 60 days. Measure diversion rate and cost per tonne. Stop rule: contamination over 15% means fix. Plan to scale only if the stream passes the stop rule. Choose one stream, such as clean wood from three sites. Weigh in, sort and weigh out, and keep the tickets. Report results to the buyer and ask what they want improved.

Speaker notes. Teach: open with the worked example. Contamination 8%: in 25 t that is 2 t. The stop line of 15% would be 3.75 t (25 x 0.15), so the pilot passes and you proceed to plan scale. Then set the activity: Run pilot review. Mark against the standard: Review has decision. Check at this level: What triggers a fix? Model answer: Contamination over 15%. Level note: Evidence: a record of results over a year and of people you have coached to a higher level.
