This report examines waste management practices in the United Kingdom, identifying improper waste disposal as an Environmentally Significant Behavior (ESB). It delves into the influences on this behavior, including a lack of strict policies, plastic waste exportation, inadequate recycling technologies, and over usage of plastic containers. The report highlights the negative impacts of these practices, such as landfill pollution and groundwater contamination. It then proposes behavioral change interventions and strategies for both the government and waste-generating organizations. Government interventions include stimulating the demand for recycled products, implementing revised frameworks for waste ownership, and enhancing waste collection systems. Organizational interventions focus on product recycling, such as concrete and battery recycling, and reducing plastic usage. The report emphasizes the need for immediate action to achieve sustainable outcomes in waste management. The report is a response to an assignment brief from the module 'Leading Change for Sustainability' and addresses learning outcomes related to describing ESBs, identifying influences, and proposing change strategies. The report also highlights the importance of government intervention and organizational actions to combat waste generation and improve waste management practices.
