**Section 3: "Role of the Society in Recycling and Circular Economy"**

Chapter 13: "Urban Mining of e-Waste and the Role of Consumers"

This chapter focuses on the circular economy, urban mining, and their intersection with consumer behavior by providing a review of existing and emergent EU regulations for enhancing the collection rate of household WEEE. Then, the chapter critically analyzes the literature on the intersection between consumer behavior and closed-loop supply chains for EEE, identified through a systematic keyword search to ensure replicability.

Chapter 14: "Compost, Social Sustainability, and Circular Economy in Guatemala"

This chapter examines several issues in Guatemala City, specifically the dynamics for initiating a new start-up composting business operating under the principles of circular economy, employment opportunities for at-risk youth, the potential market for compost both in an urban environment and for farmers, and the requirements involved in making compost in the challenging high-altitude climatic conditions of a developing world economy.
