Recycling method for polyamides and composites
Patent published on the 2026-05-21 in US under Ref US20260139119 by TURNEY KEATON [US] (Eagan James [us], Turney Keaton [us])
Abstract: [0000] A method of recycling a polymer includes steps of contacting a polyamide polymer with an acid, allowing the polyamide polymer to depolymerize in presence of the acid into an amine species and a monomer based on an olefin and carbon dioxide, and collecting the amine species and the monomer. The polyamide polymer can be part of a composite further including fibers as a reinforcing component, such that the step of collecting can further include collecting the fibers.[...]
Our summary: A recycling method for polyamides involves contacting the polymer with an acid to induce depolymerization. This process yields an amine species and an olefin-based monomer along with carbon dioxide. Additionally, if the polyamide is part of a composite, reinforcing fibers can also be collected.

Method of hydrolyzing calcium chloride brine
Patent published on the 2026-05-20 in EP under Ref EP4745093 by ENERGY AND ENVIRONMENTAL RES CENTER FOUNDATION [US] (Martin Christopher Lee [us], Musich Mark [us])
Abstract: A method of hydrolyzing a calcium chloride brine includes forming ammonia gas including reacting NH4Cl brine with Ca(OH)2 to form NH3 and the CaCl2 brine. The method includes hydrolyzing the CaCl2 brine including reacting the CaCl2 brine formed during the forming of the ammonia gas with water to form HCl and Ca(OH)2. The method also includes recycling at least some of the Ca(OH)2 formed during the hydrolyzing of the CaCl2 brine for use as at least part of the Ca(OH)2 used in the forming of the a[...]
Our summary: A method for hydrolyzing calcium chloride brine involves reacting NH4Cl brine with Ca(OH)2 to produce ammonia gas and CaCl2 brine. The CaCl2 brine is then hydrolyzed with water to generate HCl and Ca(OH)2. Additionally, some of the Ca(OH)2 produced is recycled for use in ammonia gas formation.

Abstract: Currently, the possibility for the high-value utilization of abandoned oyster shells in the Zhuhai&ndash;Macao region of Guangdong Province, China, lacks sufficient attention, leading to resource wastage. Most oyster shells are treated as kitchen waste or directly landfilled, and their potential cultural and material value is not fully realized. To address this issue, this study explores sustainable utilization pathways for local abandoned oyster shells from the dual perspectives of envi[...]
