Policies for Material Circularity: the Case of Lithium

Area of Science:

• Environmental Economics
• Resource Management
• Circular Economy

Background:

• Improper waste management leads to social risks and loss of valuable materials.
• Current market prices fail to account for the hidden costs and values associated with waste and resource use.

Purpose of the Study:

• To analyze the impact of market-based policies on material circularity.
• To determine how pricing can inform resource use and optimize material reuse.
• To evaluate policy effectiveness in reducing waste and creating value from used materials.

Main Methods:

• Economic modeling of market-based policies for material circularity.
• Analysis of a landfill tax as a first-best policy.
• Evaluation of alternative policies including taxes, subsidies, and tax-subsidy schemes.
• Numerical analysis using the lithium market and sensitivity analysis.

Main Results:

• A landfill tax is identified as the most effective policy for internalizing external costs, improving welfare, and boosting recycling.
• Alternative policies offer second-best solutions, with recycling subsidies potentially leading to increased raw material extraction and rebound effects.
• Non-market-based strategies for waste prevention and improved recyclability were also explored.

Conclusions:

• Policy design is crucial for optimizing material circularity and waste reduction.
• A landfill tax is a superior policy instrument for managing waste and promoting a circular economy.
• Understanding market dynamics and policy trade-offs is essential for sustainable resource management.
