Marine waste upcycling—recovery of nylon monomers from fishing net waste using seashell waste-derived catalysts in a CO₂-mediated thermocatalytic process

Abstract

A strategy for marine waste upcycling and CO2 utilization by the recovery of high-value monomer from fishing net waste using seashell waste-derived catalysts in the presence of CO2.

Hydrothermal Processing of Multilayer Plastic Film for Cascaded Valorization of Nonrecyclable Waste

“…Standard calibration was done using 2,5-bis­(5- tert -butyl-benzoxazol-2-yl) thiophene (BBOT, > 99.0%, SÄNTIS Analytical AG). Ash content of polymers is negligible in terms of mass balance, , thus the mass of oxygen was calculated by subtracting masses of C/H/N/S from total mass.…”

Upcycling of plastic and tire waste toward use as modifier for asphalt binder

“…57 This is most likely because most plastics are completely volatilized over 300°C, with no remaining solid residue. 58–61 There is no notable difference in the bituminous binder modification effects between conventional concrete carbon black 42,62,63 and plastic- or tire-waste-derived char. 46,64…”

“…57 This is most likely because most plastics are completely volatilized over 300°C, with no remaining solid residue. [58][59][60][61] There is no notable difference in the bituminous binder modification effects between conventional concrete carbon black 42,62,63 and plastic-or tire-waste-derived char. 46,64 Modification of bitumen with plastic-or tire-waste-derived char could enhance mechanical properties of bitumen, rutting resistance, and temperature sensitivity.…”

Pyrolysis of biogas for carbon capture and carbon dioxide-free production of hydrogen

“…The potential impact on the environment is enormous: for example, waste from old fishing nets, wind turbine blades or conventional plastic waste can be converted to energy and high-value materials. [41][42][43] Herein, biomass or biowaste has also been considered as a feedstock. 44,45 However, even though some studies on the production of syngas or hydrogen from biomass or biogas have been conducted in the past, 6,[46][47][48][49][50][51] the usage of biogas under reaction conditions of thermocatalytic pyrolysis of methane remains mostly unexplored.…”
