Sustainable Strategies for Converting Organic, Electronic, and Plastic Waste From Municipal Solid Waste Into Functional Materials

Global Challenges, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Abstract The valorization of municipal solid waste permits to obtain sustainable functional materials. As the urban population burgeons, so does volume discarded waste, presenting both a challenge and an opportunity. Harnessing materials latent energy within this not only addresses issue disposal but also contributes innovation with applications in energy, electronics, environment sectors. In perspective, technologies for converting, after sorting, into valuable metals, chemicals, fuels are critically analyzed. Innovative approaches convert organic carbon create, from plastic electronic wastes, metal–organic frameworks conversion, storage, CO 2 adsorption conversion proposed. Green hydrometallurgy routes that permit recovery precious metals avoiding noble metals’ oxidative leaching, thus their downcycling, highlighted. reclaimed hold promise use optoelectronic devices.

Embedding Pure‐Phase Fe₃C Functional Sites Into Biochar Matrix for Multi‐Scenario Electrocatalytic Ammonia Synthesis and Energy Conversion Utilization

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 7, 2025

Abstract The rational design and development of application‐oriented advanced functional catalysts is crucial for facilitating the conversion nitrogen oxides into high‐value ammonia. Herein, biomass derived from pomelo peel, which rich in metal complex groups exhibits a metallic foam‐like framework, utilized as precursor. Iron carbide (Fe 3 C) active sites are incorporated locally 2D, globally 3D biochar structure, enabling multi‐scenario green synthesis ammonia integrated energy utilization. As catalyst, Fe C‐BC achieved an yield rate up to 102120.53 µg h⁻¹ mg cat ⁻¹, with maximum selectivity 100%. A flow‐based electrolysis system featuring not only facilitated continuous but also enhanced solar harvesting. Additionally, nitrate battery employing anode exhibited high output enabled self‐driven synthesis, offering novel insights operational solutions future production. Density‐functional‐theory calculations confirmed that C actively reduces barrier key steps eNitRR process while accelerating water dissociation promote sustained proton supply. These findings collectively provide promising foundation advancing ammonia, emphasizing both efficient catalytic performance sustainable integration.
