Study Notes
Introduction to Economics of Waste
- DTU (Technical University of Denmark) presentation on the economics of waste management.
- Presentation made by Anders Damgaard in collaboration with Veronica Martinez Sanchez.
- Date of presentation: November 26, 2024.
Why is Economics of Waste Important?
- Waste management costs 0.1-0.4% of a country's GDP.
- Average cost per family per year: 1000-3000 DKK.
- Reasons for studying economics of waste:
- Waste handling is expensive and a scarce resource.
- Waste producers should pay a fair price for waste handling.
- Studying economics can lead to optimized waste management.
- Too low prices result in excessive waste generation.
- Too high prices lead to illegal dumping.
- A correct price leads to optimal solutions.
Economic Terms
-
Cost Types:
- Private cost: Money spent directly by the waste generator.
- External cost: Costs not borne by the generator (e.g., environmental impacts).
- Social cost: Total cost for society, including private and external costs.
-
Assessment Types:
- Private costs are assessed financially.
- Social costs are assessed using welfare economics.
Treatment Costs
- Collection cost comprises 50-75% of total municipal solid waste management (MSWM) costs.
- Varies based on technology, accessibility, and distances.
- Examples of techniques in the treatment of costs include:
- Collection
- Landfilling
- Incineration
- Recycling
- Others
- Landfilling was the cheapest option for a considerable period.
- However, costs increased due to land scarcity, NIMBY (Not In My Backyard) opposition, taxes to promote recycling, and higher capital and operating costs. -Landfill tax has been introduced, e.g., averaging 475 DKK (+ban)/ton.
- Incineration is expensive to start but can get cheaper in the long run due to energy revenues.
- Denmark uses incineration tax (430 DKK/ton) to promote recycling.
- Economics of scale applies to waste management
- Steady waste flow is ideal for efficient operation.
- Overcapacity increases costs per ton.
- Undercapacity leads to storage costs.
- Recycling revenues and associated costs are quite volatile.
- Sales of recyclables fluctuate widely.
- Separate collection is costly.
- Mixing recyclables reduces their quality and increases costs.
Collection Costs
- Data for a case study of collection costs.
- Collection points: 15 in total. Amount of waste from each collection point = 0.4 tonnes.
- Duration of collection round: 5 hours.
- Workers per round: 2 people.
- Diesel per round: 20 litres.
- Estimated Capital costs truck: 30 DKK/hour.
- Estimated diesel costs: 10 DKK/litre.
- Estimated Labour cost: 200 DKK/worker per hour.
Payment Schemes
- Different parties (Households/Manufacturers/etc) can be charged for waste handling.
- Payment schemes include:
- Methods based on volume, home compaction issues, or weight.
- Fixed price system—marginal cost = zero to handle high waste production.
- Various examples of payment schemes exist in Gladsaxe, Denmark.
- Rat control, renovations, and container fees.
Expansion of Collection to 10 Fractions
- Costs are divided based on waste type (residential, bulky, garden, recyclable).
Sale Price of Recyclable Materials
- Prices of recyclable materials (e.g. paper, cardboard, glass, textiles) tend to vary significantly.
Additional Considerations
- Presentation emphasized the need to discuss different cost-sharing models for waste management in various regions (comparing to Denmark).
- Discussion points included if the current systems are optimal or could be improved.
