The alkaline depolymerization reaction of poly(ethylene terephthalate) (PET) under quasi-solvent-free conditions was investigated. This is a new approach for recycling PET waste to its monomer building blocks: terephthalic acid and ethylene glycol. influence base particle size, temperature, rotational speed the employed laboratory kneader on yield in quasi-solid-solid depolymerized almost quant...

The scientific definition of polyethylene terephthalate (PET) changed for polyester in the common language. It was first manufactured 1928 and production fibre version started 1941. Nowadays, 70% artificial textile raw materials are fibres a significant amount plastic waste is generated at end life cycle clothing other products. injection moulding process introduced 1970s made it possible to de...

In this study, municipal plastic waste is used in producing paving blocks. Binders the form of melted bottles (Polyethelene Terephthalate (PET)) and water sachets (High Density Polyethylene (HDPE) with river sand, were making Mix ratios; 1:1, 1:1.5 1:2 sand-plastic considered. Sand-cement mixes adopted as controls. 230mm x 140mm 55mm blocks cast, cured at ambient temperature tested for 72-hours...

Most textile waste is either incinerated or landfilled today, yet, the material could instead be recycled through chemical recycling to new high-quality textiles. A first important step is separation since chemical recycling of textiles requires pure streams. The focus of this paper is on the separation of cotton and PET (poly(ethylene terephthalate), polyester) from mixed textiles, so called p...

Soil is a very important element in the success of development project and part foundation used. Therefore, stable soil needed to obtain required bearing capacity. Such as clay has characteristics low capacity large shrinkage. This study aims determine increase value shear strength with stabilization PET plastic waste. The purpose this see variations amount waste 0%, 3.5%, 4%, 4.5%. Method used...
