The analysis adheres to ISO 14040–44 standards and employs the ReCiPe methodology to evaluate 18 environmental impact categories, emphasizing categories such as freshwater ecotoxicity and global warming potential. The results highlight significant variations in environmental impacts across the designs, largely attributed to differences in active layer materials and manufacturing processes. Molybdenum exhibits the highest impact, particularly in freshwater ecotoxicity, while SiO₂ demonstrates the lowest overall impact. Manufacturing processes like sputtering and photolithography carried out at laboratory scale contribute disproportionately to energy consumption and environmental damage, suggesting that upscaling production to industrial efficiencies is mandatory to mitigate these impacts. Furthermore, several materials required for memristor fabrication are listed as critical by the International Energy Agency (IEA), raising concerns about supply security, resource scarcity and environmental sustainability. This analysis serves as a foundational step for optimizing memristor technologies, balancing performance demands with environmental stewardship.

This paper proposes HAPSO, a hybrid metaheuristic that integrates Ant Colony Optimization (ACO) for initial virtual machine (VM) placement with discretization-aware Particle Swarm Optimization (PSO) for migration optimization, tailored for energy- and carbon-efficient VM consolidation in green cloud datacenters. In the first stage, ACO performs energy-aware placement of VMs onto physical hosts, emphasizing global search to satisfy resource constraints and minimize power usage. In the second stage, discrete PSO refines the allocation by migrating VMs from overloaded and underutilized hosts, focusing on local optimization to improve consolidation and reduce resource wastage. The novel contributions include: sequential metaheuristic hybridization, a system-informed particle initialization (seeding PSO with ACO output to ensure feasible starting solutions) and a heuristic-guided discretization method (mapping continuous updates into valid VM–host assignments), and a multi-objective fitness function that minimizes active servers and unused capacity to enhance efficiency. We implement HAPSO in CloudSimPlus and evaluate it on workloads ranging from 500 to 14,000 VMs using realistic trace-driven simulations. Results show that HAPSO reduces energy consumption by 6.72 % on average (up to 10.0 %) and carbon emissions by 10.5 %, with savings peaking at 25.8 % in mid-scale workloads, compared to the ACO baseline, while maintaining SLA compliance.

Therefore, it is crucial to determine the optimal size and placement of RDGs to enhance overall performance of the DNs.
