| 概要 |
Zeolites’ synthesis from low-value precursors and their environmental benefits are reviewed. A case study approach is used where natural resource-based synthesis and a commercial-chemical route are co...mpared for environmental accountability, focusing on energy and material consumption and greenhouse gas emissions. Using natural or waste raw materials is recommended; it significantly reduces energy consumption by 0.02 kWh, lowers CO_2 emissions by 0.3 kg, and decreases material costs by 6 USD/kg of zeolite produced, compared to chemical precursors. Waste-materials usage for zeolite fabrication is highlighted for its notable advantages, including land-space conservation, positive health impacts, and pollution mitigation. Key conditions for sustainable synthesis include proper aging, alkaline-fusion, aluminum-content adjustments, and waste-liquid recycling.続きを見る
