Go green by recycling
Fun text and upbeat illustrations will inspire readers to learn about recycling. Comprehension questions, fun facts, and critical thinking questions keep readers engaged and thinking while they read through an interesting narrative with diverse characters.
Cycling and Recycling
Technology has long been an essential consideration in public discussions of the environment, with the focus overwhelmingly on creating new tools and techniques. In more recent years, however, activists, researchers, and policymakers have increasingly turned to mobilizing older technologies in their pursuit of sustainability. In fascinating case studies ranging from the Early Modern secondhand trade to utopian visions of human-powered vehicles, the contributions gathered here explore the historical fortunes of two such technologies—bicycling and waste recycling—tracing their development over time and providing valuable context for the policy successes and failures of today.
Recycling materials
Discusses the basics of recycling, including what materials are most commonly recycled and how the process of recycling works.
Plastic Waste: Challenges and Opportunities to Mitigate Pollution and Effective Management
The present world is now facing the challenge of proper management and resource recovery of the enormous amount of plastic waste. Lack of technical skills for managing hazardous waste, insufficient infrastructure development for recycling and recovery, and above all, lack of awareness of the rules and regulations are the key factors behind this massive pile of plastic waste. The severity of plastic pollution exerts an adverse effect on the environment and total ecosystem. In this study, a comprehensive analysis of plastic waste generation, as well as its effect on the human being and ecological system, is discussed in terms of source identification with respect to developed and developing countries. A detailed review of the existing waste to energy and product conversion strategies is presented in this study. Moreover, this study sheds light on sustainable waste management procedures and identifies the key challenges to adopting effective measures to minimise the negative impact of plastic waste. Highlights A comprehensive analysis of global plastic waste generation and its effect on land and marine environment is conducted. Plastic waste management technologies for both land and marine environment are reviewed thoroughly. The modern technologies for waste-to-energy and waste-to-production conversion are discussed in this paper. The potential challenges and a way forward for sustainable management technologies are presented.
Recycle every day
Introduces the concept of recycling and why it is beneficial for our Earth, and offers fun ways to recycle and reuse, at home and in the community.
Design Implications of Extended Producer Responsibility for Durable Products
We analyze product design implications of extended producer responsibility (EPR)-based take-back legislation on durable goods. In particular, we observe that durable product design incentives under EPR may involve an inherent trade-off that has not been explored to date: Durable goods producers can respond to EPR by making their products more recyclable or more durable, where the former decreases the unit recycling cost and the latter reduces the volume the producer has to recycle. When these two design attributes do not go hand in hand, as is the case for many product categories, product design implications of EPR can be counterintuitive. We find that more stringent collection targets (defined as the portion of total product volume to be collected) or recycling targets (defined as the portion of each collected product unit to be recycled) may imply reduced recyclability or durability. Moreover, although collection and recycling targets appear to be similar EPR implementation levers for increasing the total amount of materials recycled, they, in fact, have opposing effects in driving producers’ design choices. As a result, EPR may have unintended consequences for the environment. A calibrated numerical study on the photovoltaic panel (PVP) industry allows us to show that more stringent EPR requirements (such as those proposed by the recent recast of the WEEE directive) can lead to a PVP technology choice with lower recyclability and higher durability and, consequently, result in higher greenhouse gas emissions. These results call for a careful analysis of the benefits of EPR legislation in the context of durable goods. The online appendix is available at https://doi.org/10.1287/mnsc.2018.3072 .

Manufacturers’ Competition and Cooperation in Sustainability: Stable Recycling Alliances
Rather than organizing disposal of consumer-generated waste themselves, many states and countries have passed legislation that makes producers responsible for the proper disposal (i.e., recycling) of the products that they bring to the market. We study the stability of producers’ strategies emerging under such legislation. In our paper, the producers compete with multiple differentiated products in consumer markets but may consider cooperating when recycling those products to benefit from economies of scale. Products made by different producers or sold in different markets might still be considered for joint recycling. Our main questions are when and whether firm-based recycling strategies (i.e., separately recycling products falling under same brand) or market-based recycling strategies (i.e., separately recycling products falling in the same product category) emerge as stable outcomes. To that end, we analyze a series of simple producer-market configurations. We first look at an asymmetric market model with two producers making three products in two markets, and then, we look at a symmetric market model with two producers competing with four products in two markets. Our results show that, with intense market competition and differentiated market sizes, producers may recycle their products on their own without cooperating with others. In some instances, they can add a product from their competitor to their recycling mix. Because these outcomes are never socially optimal, they may reduce social welfare and require government intervention. Otherwise, with less intense competition or more equitable market shares, all-inclusive (market-based) recycling is the most common stable outcome with high (low) scale economies, and the firms’ independent choices might lead to social optima.

Implementation of Blockchain Technology in Waste Management
Implementing blockchain technology in waste management is a novel approach to environmental sustainability and accountability challenges in our modern world. Blockchain, a technology that enables decentralized and immutable ledgers, is now being re-imagined as a tool to revolutionize waste management. This innovative approach aims to improve waste management transparency, traceability, and efficiency, resulting in significant environmental and economic benefits. In traditional waste management systems, the tracking and disposal of waste materials are not transparent and can be vulnerable to fraud, mismanagement, and inefficiency. Blockchain technology provides a secure and transparent platform for recording every step in the waste management lifecycle, from waste generation to collection, transportation, recycling, or disposal. Every transaction in the blockchain is recorded in a tamper-proof manner, enabling real-time monitoring and verification of waste-related data. This paper introduces the concept of using blockchain technology in waste management. The main goal of this work is to show the implementation of blockchain technology in an existing waste management company, using smart contracts in the recycling process to provide transparency. Also, the digital product passport was redefined in terms of circular economy and waste recycling.
