We present a comprehensive model to computationally study molecular structure development in the recycling extrusion process of low-density polyethylene (LDPE) and provide initial results versus reported experiments as guidance. Molecular weight distribution (MWD) branching (BD) are modeled by applying combination population balance modeling, method moments pseudo distributions. Special cares h...

Environmental pollution by microplastics (MPs) has become a global problem, but little is known about MPs in soils. This because MP extraction methods from soils have not yet been standardized. In this study, we tried to establish simple and economical method extract soil using the buoyancy of canola oil density separation process sodium chloride (NaCl). addition, incineration was adapted evalu...

Many road construction and maintenance projects are increasingly using recycled material as pavement material. Most of the times, generic sustainability evaluations ascribed to products without fully considering their performance. The potential environmental benefits various alternatives can be analytically evaluated with Life Cycle Assessment while many performance indicators found through lab...

Pada jalan di daerah Aceh banyak dijumpai kotoran sapi berserakan jalan. Kotoran mengandung sangat unsur hara kadar air yang cukup tinggi dapat diduga faktor perkerasan Salah satu cara dalam m...

A powerful simple biochar catalyst derived from nanocellulose was applied to the catalytic upcycling of waste plastics into H2 and liquid fuels for first time. For results model low-density polyethylene (LDPE) pyrolysis, C8-C16 aliphatics monocyclic aromatics were dominant constitutes product with yields ranging 22 68 wt%. At temperature 500 °C LDPE ratio surpassing 3, could be completely degra...

Hydrogen is largely produced via natural gas reforming or electrochemical water-splitting, leaving organic solid feedstocks under-utilized. Plasma technology powered by renewable electricity can lead to the sustainable upcycling of plastic waste and production green hydrogen. In this work, low-temperature atmospheric pressure plasma reactors based on transferred arc (transarc) gliding (glidarc)...

This study investigates the potential migration of plasticisers, plastic components and additives from several plastic water bottles. Compounds studied were phthalates (dimethyl phthalate, di-n-butyl phthalate, benzylbutyl phthalate, bis(2-ethylhexyl) phthalate), bis(2-ethylhexyl) adipate, octylphenol, 4-nonylphenol and bisphenol A. Polycarbonate (PC), high-density polyethylene (HDPE), low-dens...

Sunscreens play a fundamental role in skin cancer prevention and in protection against photo-aging. UV filters are often photo-unstable, especially in relation to their vehicles and, being lipophilic substances, they are able to interact with plastic packaging. Finally, UV filter stability can be significantly affected by the routine use of the product at high temperatures. This work aims to st...
