Abstract Plastic pollution levels have increased rapidly in recent years, due to the accumulation of plastic waste, including polyethylene terephthalate (PET). Both high production and lack efficient methods for disposal recycling affect diverse aquatic terrestrial ecosystems owing rates plastics. Traditional chemical physical degradation techniques caused adverse effects on environment; hence,...

This study assesses the impacts of recycling waste polyethylene terephthalate (PET) plastic bottles as a partial substitute for fine natural aggregates on workability, mechanical, microstructural, economic, and thermal properties concrete. The mix design adopts concrete ratio 1:2:4 grade M25, 0.55 water/cement ratio, ordinary Portland cement (OPC) binder, varying proportions heat-processed PET ...

Abstract Supercritical CO 2 -assisted extrusion technique was used to produce flame retarded foams from recycled poly(ethylene terephthalate) (rPET). Synergistic combination of aluminium-alkylphosphinate retardant (FR) and natural montmorillonite (MMT) utilised provide adequate retardancy at moderate loadings, i.e. with less than 9% additives. Addition FR found increase the rate degradation dur...

Different plastics recovered from a local urban solid waste plant were collected before landfilling, separated, and classified by families, i.e. polyethylene (PE), polypropylene (PP), high impact expanded polystyrene (HIPS EPS, respectively), terephthalate (PET), polyvinyl chloride (PVC). A systematic pyrolysis study was carried out to compare the different behavior registered in each plastic t...

Mixed plastic waste is challenging for any recycling process. Here, an enzymatic process compared with a biotechnological upcycling valorizing mixed constituted by PLA, PET, and PP. Both routes are modeled in Aspen Plus, analyzed bottlenecks, cost drivers, sensitivity regarding microbial performance. While only viable uniform feedstock, operating at optimized conditions reveals the potential to...

The circular economy is a path that society, governments, and business must adopt to develop viable sustainable model for plastic production. Following the route guided by United Nations new laws of European Union, such as Green Deal, it will be able put an end great problem this era, inadequate treatment management waste. On plastics production ladder, poly(ethylene terephthalate) (PET) ranks ...

Plastics are versatile materials used in a variety of sectors that have seen rapid increase their global production. Millions tonnes plastic wastes generated each year, which puts pressure on waste management methods to prevent accumulation within the environment. Recycling is an attractive disposal method and aids initiative circular economy, but recycling still has challenges overcome. This r...

In this study, 12 organic waste materials were subjected to TG/DTG thermogravimetric analysis and DSC calorimetric analysis. These analyses provided basic information about thermochemical transformations degradation rates during pyrolysis. Organic divided into six groups as follows: paper, cardboard, textiles, plastics, hygiene waste, biodegradable waste. For each group, two selected be studied...
