International interest in using waste-to-energy (WtE) technology toward a circular economy (CE) is developing, spurred by environmental challenges such as inefficient solid waste dumping, pollution, and resource depletion. Incineration, pyrolysis, gasification, landfill, anaerobic digestion are standard WtE technologies. Although these methods have been used for many decades, all countries try to implement the best plans based on their technologies capacities. Therefore, an up-to-date comprehensive study needed evaluate existing barriers draw logical roadmap CE. this review addresses recent policies adopted developed developing Based findings, most seek cost-effective environmentally sustainable pathways CE; meanwhile, international collaboration governmental support overcome find economically viable plan both future.

Optimizing Sustainable Tourism in North Sumatra: An Analytic Hierarchy Process Approach Using Alternative Sustainability Metrics

Journal of Research in Mathematics Trends and Technology, Journal Year: 2024, Volume and Issue: 6(1), P. 35 - 45

Published: March 30, 2024

Sustainable tourism focuses on minimizing negative impacts the environment and local communities while maximizing economic benefits. This study identifies sustainable tourist destinations in North Sumatra using Analytic Hierarchy Process (AHP) with various sustainability criteria. Beyond common criteria (environmental, economic, social), it includes alternative metrics like carbon footprint, biodiversity, energy consumption, water management, community participation, revenue, air quality, visitor satisfaction. Hypothetical scores for 15 were analyzed, weights set based priorities. Simulations considering budget constraints optimized destination selection. Results indicated that Pulau Samosir, Air Terjun Sipiso-Piso, Taman Alam Lumbini scored highest sustainability. These selected their top performance against The concludes incorporating provides a comprehensive perspective, making model valuable tool policymakers managers. It also demonstrates significant can be achieved even within constraints.
