Engineeringplastics refer to thermoplastics having the higher strength per unit weight than the usual metallic materials, yet having low material cost. Some examplers of engineeringplastics include acrylonitrile butadiene styrene (ABS), polyetheretherketone (PEEK), polyetherketone (PEK), polyethylene terephthalate (PET) and polycarbonates (PC). The mechanical and thermal properties are better in comparison with the vastly and extensively utilised commodity plastics such as polystyrene (PS), polypropylene (PP), polyethylene (PE) and polyvinyl chloride (PVC) (Hiroki and Etsuo, 2004).
I conducted my master thesis at DSM EngineeringPlastics B.V., Emmen. This company provides the ideal combination of management and technology that was needed for this thesis. Due to the complexity and abstractness of the assignment, I had a very hard time dealing with it. However, I can truly state that this thesis was a boost for my personal development and an instructive experience.

wt% content of talc. However, impact strength was dras- tically changed over 10 wt%, it was about 2 to 5 kJ/m 2 . This tendency was similar to the high E-GMA content results, that is, the results of Figure 3. PBT is engineer- ing plastics and polyester, thereby, it is considered to indicate the good compatibility between PET and PBT as compared with other engineeringplastics. Consequently, PBT inhibit the crystallization of PET due to protect to grow up the nucleation of lamella body. As a result, im- pact strength of RPET/E-GMA/PBT blends had kept the high value with increasing the PBT content. In the case of talc blends, it is considered that crystallization is in- creased with increasing the content of talc. However, the impact strength indicated the lower value at high content of talc, because crack or delamination is formed readily between RPET and talc filler.
100 °С 400 °С even though the hydration and autoclave effect took place because the subsequent gain in CS that would have been achieved was nullified as a result of a large amount of voids within the plast-cretes . The CS of the plast –crete decreased further from the 400 °С 800 °С . This could also be attributed to the poor interfacial bonding between the plastics and hydrated cement gel, uneven expansion of various components within the concrete which lead to the propagation of microcracks. These reductions in CS was even more pronounced as the quantities of waste plastics increased in the plast-crete (s) from 10% to 50% as shown in Figure 6 and Figure 7. Reduction in CS in the plast- crete from the 400 °С 800 °С can also be attributed to the complete melting and thermal degradation of the waste plastic in the plast-crete and also drastic changes in chemical composition as temperature increased [16, 17, 18].

Plastic is considered an individual gift of modern science and technology to mankind. Nowadays, plastics and synthetic polymers are mainly produced from petro chemical elements, which do not decompose, thus resulting in the environmental pollution. Bacterial plastic is usually defined as an exciting new area of research, where naturally synthesized bacterial polymer, such as the lipid storage material PHB is being used as raw materials for plastic based packaging materials. Poly-β-
The following conclusions are made based on experimental results from the present investigation. The physical properties of shredded waste plastics and its reaction with acid and alkalis were tested in laboratory and the results shows that the shredded waste plastics is of having specific gravity of 1.108 and its aspect ratio is within the limits stipulated in IRC:44-2008, hence this waste plastic materials in shredded form is suitable for fibre reinforcement in cement concrete. Experimental results indicates that the workability is decreased due to the addition of plastics fibres to concrete mixes, and it has been made workable to the required degree by adding different percentage of super plasticizer on trial basis and optimum percentage of super plasticizer arrived and adopted in this study.
Production of bioplastics is getting increased attention from both public and private actors. However, the term bioplastics often leads to confusion because it includes both plastics that are bio- and fossil-based. A plastic can be a bioplastic in three different ways; (1) bio-based and non-biodegradable, (2) bio-based and biodegradable or (3) fossil-based and biodegradable. This paper only considers bio-based plastics, both biodegradable and non-biodegradable, since the aim is to explore the implications of a fossil-free plastic production. Bio-based plastics are still in their infancy and subject to substantial development efforts. They have so far mostly been used in special applications, but the range of applications is ex- pected to increase through recent technical advances, such as production of conventional plastics from biomass. The most prominent example is polyethylene from sugarcane ethanol (C 2 H 5 OH) from Brazil (Braskem, 2015). Global projections of bio-
Waste is an inseparable part of human activi- ties. With the growth of the number of population and industrial development, the amount of waste increases, therefore, a problem of their storage appears. In developed countries annual produc- tion of municipal waste per one inhabitant is from 400 to 760 kg , and global production of mu- nicipal waste is estimated at 1.2–1.6 billion tons . In the increasing stream of waste, the share of plastics which do not decompose in natural environment increases. This is why plastics are subjected to recycling or utilisation. The latter form is also used in case of toxic and hazardous materials, such as medical wastes . The most common form of utilisation combustion, howev- er, due to the fact that the process generates harm- ful gases, more and more frequently pyrolysis or gasification is used as alternatives.
Another benefit of an ERP system is that it not only schedules the production but also connects to other departments within the company. The inventory and purchasing of raw materials depend on the production activities of a company. The production then, in the case of Dupo, depends on incoming customer orders. Integrating the information stream in these departments allows for more effective operational management. Overall it is a more complete system that one could ever program in an Excel file. Implementing an ERP system is a long process, which includes decisions about vendors, training, change management, and process engineering. Therefore, further research should be done about the impact of implementing ERP at Dupo, before any steps are taken.
thread, the radial force generated by the 30° thread is approximately one-half that of the 60° thread. In the photo at right, the plastic boss with a 60° thread fastener shows radial stress and subsequent damage. The plastic boss with a special fastener for plastics shows reduced radial stress.
ABSTRACT: Plastic waste is a major environmental and public health problem at Jamshedpur. Plastic shopping or carrier bags are one of the main sources of plastic waste. Plastic bags of all sizes and colors dot the city‘s landscape due to the problems of misuse, overuse and littering. Besides this visual pollution, plastic bag wastes contribute to sblockage of drains and gutters, are a threat to aquatic life when they find their way to water bodies, and can cause livestock deaths when the livestock consume them. Furthermore, when filled with rainwater, plastic bags become breeding grounds for mosquitoes, which cause malaria. Burning of these chlorine-containing substances releases toxic heavy metals and emits noxious gasses like dioxins and furans. They are the most toxic and poisonous substances on earth and can cause a variety of health problems including damage to the reproductive and immune system, respiratory difficulties and cancer. Land filling of plastics into properly designed disposal sites takes up valuable room in the site for a non-toxic, non-leachable, non-decomposable material. Whether plastic is a menace or not depends how we use it and how we dispose of it minimizing the impacts on the environment. We are collecting the threat(waste plastics) from the source, segregating the waste and shredding the same into 2-4mm size and mixing the shredded plastic to make a coating over the aggregates used for road construction providing the road a tremendous strength at no extra cost. Plastic gets coated over stone and the hot plastic coated stone is mixed with bitumen (tar) and the mix is used for road laying.
We also expect the group to be more conservative in its cash flow management, including its cash dividend payments, to weather the industry downturn and meet capital expenditure needs. The FP group lowered its cash dividend payout ratio below 60% in 2012 from over 80% previously. In addition, we expect the four core companies' large long‐term investments not consolidated in our analysis of the four core companies, to provide additional financial flexibility. These investments include the highly profitable 23%‐owned Formosa Plastics Corp. USA and wholly owned Mai‐Liao Power Corp., which contributed about NT$13 billion in equity income to the four core companies in 2012.
