In order to meet the technical specifications in roofing applications, bitumen used for this purpose is standardly modified by polymers. This, general, allows re-use of recycled polymer during production polymer-modified (PmB), simultaneously reducing amount polymeric waste. Recycling processes, however, may degrade or contaminate polymers, leading reduced crystallinity and lower melting temper...

As one of the world’s most abundant biomass, lignocellulosic materials such as rice husk (RH) has been recognized for its various potential usages. Electrospun nanofibrous mats have fabricated from natural and synthetic polymers offers a wide range promising criteria suitable wound dressing applications. Attuned to environmental concerns in current years led finding new resources replace polyme...

This article analyzes the effect of fire on plasterboards with aggregates plastic cable waste, considering plaster coating as a strategy to reduce flammability added polymers. A real test was performed, using direct set in Madrid station, and theoretical estimate composition gas emissions, focused CO2 CO, during type room is presented. The results reflect that there no clear trend between evolu...

Due to the rising worldwide demand for green chemicals, bio-based polymer market is anticipated expand substantially in future. The synthesis of functional polymers has been a burgeoning area research decades. primary driving force behind development their compostability and biodegradability, which are critical given public concern about waste. Significant advancements method refining biomass r...

Lignocelluloses residues from the post-harvest crop are receiving great scientific attention nowadays. Generally, composite materials based on lignocelluloses waste present low density and weight, better insulation properties compared with those petroleum-based. This study presents results of experimental investigations regarding soundproofing capabilities for a material expanded perlite (EP) n...

Refuse-derived fuel (RDF) is a mixed industrial waste, which often contains combustible materials (cellulose, polymers, rubber, biomass, etc.). The RDF waste precursor subjected to thermo-oxidation treatment at 300℃, followed by carbonizations 600℃, and high temperature hydropyrolysis 800℃. obtained nanoporous carbon material was detailed characterization low nitrogen sorption, elemental analys...

Over the years, petrochemical industry has developed a plethora of polymers that are contributing to well-being humanity. Irresponsible disposal used plastics has, however, led buildup litter, which is fouling environment, harming wildlife, and wasting valuable resources. This paper critically reviews challenge opportunities in converting plastic waste into feedstock for industry. It discusses ...

Waste rice straw biomass and its burning in open fields have become a serious issue of greenhouse gases emission air pollution, which has negative impact on public health the environment. However, environmental this agro-waste can be mitigated by diverting it towards green biorefinery through sustainable production energy, biofuels, organic chemicals, building blocks for various polymers. This ...
