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.
