The search for alternatives to petroleum-based thermoplastic polyamide elastomers (TPAEs) has recently drawn great interest. In this study, a bio-massed TPAE, PA12,36, was synthesized using 1,12-dodecanediamine (DDA) and fatty dimer acid (FDA, PripolTM1009) precursors via catalyst solvent-free melt polycondensation. molecular structure weight of the PA12,36 were characterized by 1H NMR, FTIR, GPC. displayed low melting temperature 85.8 °C, an initial degradation 425 glass-transition 30.4 whereas it sustained satisfactory tensile strength (10.0 MPa) superior strain at break (1378%). Furthermore, foamed supercritical CO2, cell size, density, porosity determined. entangled long-chained FDA component generated physically crosslinked network, which promoted viscosity against elongations foam growth increased foamability significantly. As result, uniform structured cellular foams with diameter 15–24 µm high density (1011 cells/cm3–1012 cells/cm3) successfully achieved. foaming window widened from 76 81 expansion ratio 4.8 9.6. Additionally, presented better creep shape recovery percentage (92–97.9%) sturdier dimensional stability. This bio-based is promising candidate replace elastomer engineering applications, particularly shoe soles.

Upcycling is identified as a process of the transformation waste materials to which it possible give value artistic or environmental quality. To date, greatest use upcycling can be found in design, art and fashion sectors. As other sectors, one biggest challenges construction industry future search for new ways reuse discarded materials. In this sense, technique recovery removed but with much lower energy resources than regeneration recycled material. With respect these issues, aim paper present results design experimentation aimed at defining methodologies tools building components from decommissioning renovation processes existing buildings, an approach that integrates both disassembling re-assembling elements, line sustainable development climate neutrality goals European Union aims achieve by 2050. The methodology used made field experiment means creation prototype evaluate study which, if on hand define appropriate procedure upcycling, highlighted how procedures save reduce emission CO2 environment. specific case, gave following results: savings 2038.92 kWh; reduction 641.80 kg compared similar intervention scratch. Therefore, definition replicable scalable operational activity applied architecture allows, those elements still have useful life, can, therefore, architecture, profitable contribution circular economy.

Epoxy resin (EP) is a widely used thermosetting resin. However, its cross-linked structure poses big challenge for recycling into value-added products. This study advanced the of acid anhydride-cured epoxy using solid-state shear milling (S3M) technology. Through this process, C–C backbone and C–O cross-linking bonds in resins were destroyed, generating C═O −OH reactive groups powder (REP). When REP-20 (number cycles) incorporated as an active filler original curing system, tensile strength increased from 34.2 to 51.6 MPa, flexural 57.1 82.3 which 50.1 44.1% enhancement, respectively, compared REP-1. Futhermore, REP can serve with other agents, such agent 593 4,4-Diaminodiphenylmethane (DDM). By employing enhance surface roughness hydrophobic coating, contact angle 144.1°. Additionally, when was utilized filter column, it effectively separated water oil separation efficiency up 99%. After 10 cycles operation, flux filtration devices remained unchanged, demonstrating excellent stability reusability. provided new way recycle produce functional fillers applications coatings oil–water separation.
