the study was undertaken with the objectives to: (1) study the present status of plastic waste management and the existing phnom penh household willingness and their influence factors to segregate plastics for recycling and reuse (plastics & non plastics); (2) study how other cities encouraged and obtained the participation of their population in plastics recycling and reuse and (3) recommend w...

Although thermal recovery of waste plastics is widely practiced in many European countries, reliable information on the amount of waste plastics in the feed of waste-to-energy plants is rare. In most cases the amount of plastics present in commingled waste, such as municipal solid waste, commercial, or industrial waste, is estimated based on a few waste sorting campaigns, which are of limited s...

it has been proven that polyolefins specially low density polyethylene (ldpe), are resistant against degradation and microorganism attacks; thus, one of the most important properties of industrial plastics, is their environmental biodegradability. since plastics are being widely used in agriculture, horticulture and packaging, meeting this requirement becomes increasingly dificult (specially in...

This article explains the history, from 1600 BC to 2008, of materials that are today termed 'plastics'. It includes production volumes and current consumption patterns of five main commodity plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene and polyethylene terephthalate. The use of additives to modify the properties of these plastics and any associated safety, in use, issu...

Plastics are becoming increasingly utilized in consumer and industrial products. Over five million tons of plastics are used each year. In the UK in 2010 approximately 38% of the plastics consumption was used in packaging materials, with a quarter of this in production of plastic bottles. In the automotive industry an increasing number of large parts are being made from plastics due to the dema...

little is known about the interaction of tissue conditioners and modeling plastics. this study evaluates the influence of a variety of commercial tissue conditioners on alteration of viscoelastic properties of modeling plastics.in this in vitro study, the dynamic viscoelastic properties of four commercially available tissue conditioners (tc), visco-gel (vg), gc soft-liner (sl), fitt (ft), and c...

Plastics in the pharmaceutical industry are as ubiquitous as endotoxins. From solution containers to medical devices, plastics are not just commonplace. they are often the best material for the application. Because plastics are formed at very high temperatures that easily destroy endotoxins, plastics should be expected to be endotoxin-free. Unfortunately, the often excessive and usually uncontr...

Reverte oxo-biodegradable additive masterbatch and bags are not compliant to the criteria stated in AS4736 which is an Australian Standard® Biodegradable plastics—Biodegradable plastics suitable for composting and other microbial treatment documents. Well Plastics UK are in the same opinion as the Oxo-biodegradable Plastics Association that bio-based is the wrong technology (reason is as attach...

The aim of this work was to make biodegradable plastics from renewable resources. Paper-based biodegradable plastics were produced via a sol-gel process by using zinc chloride solution. The optimum conditions were a zinc chloride concentration of 65%, reaction temperature of 70 °C, reaction time of 5 s, aging time of 3 h, and glycerol concentration of 10%. Fourier transform infrared spectroscop...
