The damage condition of paved roads in Indonesia will increase as the number vehicles passing and erratic weather conditions. One way to reduce road is quality asphalt mixture. To can be done by adding additional materials such plastic waste into In this study, simulated use neural networks determine optimal value analysis influence polypropylene polyethylene terephthalate mechanical thermal pr...

Since curing remains an essential parameter that directly influences concrete strength and durability, this research aimed at evaluating the effects of water, sodium chloride (NaCl), carbonate (Na2CO3) regimes on concrete’s durability. The design mix was composed ratio 1:2:4, hydrated ordinary Portland cement with a water/binder 0.50, river sand as fine aggregates, varying percentages heat-proc...

Recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. Since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. In the present study, we used a solution electrospinning technique to synthesize nano/micr...

According to the European circular economy strategy, all plastic packaging placed on market by 2030 has be recyclable. However, for recycled plastics in direct contact with food, there are still major safety concerns because (non-)intentionally added substances can potentially migrate from polymers into foodstuffs. Therefore, Food Safety Authority (EFSA) derived very low migration limits (e.g.,...

Abstract Magnetic Mg-Al-O@Fe3O4 micro particles were synthesized by coating nanosized Mg-Al double oxides onto Fe3O4 particles. The formed hierarchical structure gave a high active surface area, which enabled these to work efficiently as catalyst in the glycolysis of poly(ethylene terephthalate) (PET). bis(hydroxyethyl) terephthalate (BHET) yield reached above 80 mol% presence 0.5 wt% reaction ...

The United States generates the most plastic waste of any country and is a top contributor to global pollution. Multiple end-of-life strategies must be implemented minimize environmental impacts retain valuable material, but it challenging compare options that generate products with different lifetimes utilities. Herein, they present material flow model equipped consequential life cycle assessm...

The present work discusses the influence of additives, designated as co-adjuvants agents chemical activation, containing nitrogen on their structure, activated carbons (ACs) produced from waste polyethylene terephthalate (PET) and cork by with KOH, at 973 K. used were urea, 2-chloro-4,6-diamino-1,3,5-triazine, (2-hydroxyethyl) urea polyethylenimine. ACs, PET, only KOH presented a porous volume ...
