Abstract:

Plastic type material is a material that is often used by many people in everyday life, the use of plastic materials, especially working in the world of health, industry or household, many people make plastic materials such as glass, plates, and more used as the necessities of everyday life. The sheer amount of plastic use has the potential to increase Polluttion and it is also very bad for the environment, mostly plastic materials are dumped without further processing, to reduce the impact of plastic materials needed for chopping tools to reduce the accumulation process.

Abstract:

Currently, one of the important areas for increasing the reliability, durability and efficiency of oilfield equipment is the use of plastics instead of non-ferrous and ferrous metals. The qualitative feature of plastics compared to other materials indicates that they are materials with unlimited possibilities both in terms of their inherent properties and in terms of their use as a structural material. Plastics have found extremely wide application in the oil industry. The design features of plastic parts and units of oilfield equipment and the specifics of operating conditions show that the m

The increasing consumption of plastics and plastic products results in correspondingly substantial volumes of waste, which poses considerable environmental burdens. With the ongoing environmental actions, the application of circular economy on this waste stream is becoming inevitable. In this paper, the topics of plastics recycling, circular economy on plastics, and challenges to plastic waste recycling are critically reviewed.

Plastic reappears constantly throughout Nengudi’s oeuvre, a choice most often passed over as merely an economic or logistical one, plastic being both cheap and ubiquitous. In this article, I push against this too-easy explanation, arguing that while it might have started as a material of convenience and low cost, plastic became the medium by which Nengudi could articulate evolving attitudes towards the body. In her earliest work, plastic appears as a playful

This difference value would be caused by residual stress, work hardening and fiber texture due to plastic working. When degree of plastic deformation equal zero ("t=0), the fatigue limit rati

Plastic is a major environmental pollutant in the environment. The petroleum derived plastics are mostly non biodegradable and take long time to break down. Thus ecosystem is getting affected by this pollution. So the approach to produce plastic using microbes is a novel approach. Bio-plastics are generally bio-based, they may be or may not be biodegradable but their properties are closed to synthetic polymers. In biodegradation process micro-organisms convert plastics into water, carbon dioxide, and compost. Bioplastics are generally prepared from biomass such as polysaccharides, starch, lipi

Plastic working technologies are frequently applied nowadays, as parts can be produced with larger productivity and smaller material loss compared to other technologies, at the same time the mechanical properties of parts are more favorable. Usually large tensile, pressure, bending or torsional forces, torques are required during plastic working. While pneumatic, hydraulic or electric energy is required to generate these. Used energy is determined by the losses of the energy required for working and that of energy conversion. The losses of working equipment are determined by mechanical losses

Accordingly, the effect of work hardening on fatigue strength about this material is very small.

The paper first gives a visco-plastic model considering dynamic recrystallization in detail; secondly gives the applied finite element formulation and compiles an finite element program in Visual Fortran 6.5 based on the updated Lagrangian formulation rigid-plastic finite element; thirdly the material parameters

AbstractThe paper analyses the characteristics of plasticity and microstructure of magnesium alloys with lithium meant for hot plastic working with different lithium content. The alloys were prepared in conditions of vacuum smelting. Achieved ingots were subject to hot extrusion. Tests on Gleeble simulator were conducted to assess the susceptibility of tested alloys to plastic forming in conditions of hot plastic working. For tested alloy the activation energy was marked for hot plastic deformation and plasticity characteristics in function of Zener-Hollomon parameter. After the analysis of th

Abstract:

As the industry develops, plastic consumption continues to increase every year. Today, plastic pollution stands out as an important problem among environmental concerns. Plastic waste creates negative impacts on the environment, both on macro and micro levels, due to their types, size, and resistance to degradation. Recycling is of great importance its contributions to both nature and economy. The main purpose of this study is to determine the waste management, economic efficiency, sustainability and recycling awareness levels of companies operating in the plastic recycling industry using surv

Abstract:

Plastic, which is originated from petrolum, is possible to turn it to alternative fuel. Moreover in 2008, the estimated amount of midden in Indonesia reached 38.5 million tons per year with the largest compositions are organic waste (58%), waste plastics (14%), waste paper (9%) and wood waste (4%) (Ministry of Environment, 2008). Meanwhile in Depok City, the amount of waste which goes to Depok City’s landfill waste is 350-400 tonnes / day (Head of Technical Unit Landscape Depok City Sanitation Department, 2012). From the data, above, can be confirmed using plastic waste as an alternative fuel

Abstract:

Abstract The aim of this paper is to present a granulate manufacturing machine that will be used for recycling plastics in a laboratory at the Sapientia University. In order to produce granulates of recycled plastics the plastic part has to be ground and then extruded. The extruded polymer filament then can be converted to granulates. We present the working principle, design steps, structure and 3D model of a small scale granulate producing machine with a cost-effective approach

Abstract:

Unbound granular materials (UGMs) have advantages in their water storage and drainage capabilities in permeable pavement, which is a benefit for urban sustainable development. The plastic strain of UGM is a crucial mechanical property that affects its design and construction. During its service life, repeated load only, repeated load after infiltration, and simultaneous action with load and infiltration are the three inevitable working conditions that will impact plastic strain, especially dynamic water infiltration. How these working conditions influence plastic strain needs to be focused on
