Types Thermo Plastic Thermosetting Plastic Thermo Plastic These materials can be reheated and reformed in to new shapes for a number of times without significant changes in their properties most of the thermo plastic consists of the long chains mainly of carbon atoms covalently bonded together and sometimes nitrogen oxygen and sulpher are
Chapter overview. 2 weeks Mixtures was first introduced in Gr. 6 so learners should already be familiar with these concepts. Learners would have also looked at some of the physical methods of separating different types of mixtures (including hand sorting sieving filtration) and this year we will explore some additional methods in more detail (including distillation and chromatography).

· Electronic waste or e-waste is an emerging problem with developed nations as with developing nations. In the absence of proper collection and disposal systems awareness and proper regulations the problem is rather more acute in developing nations. These wastes are environmentally hazardous on one hand and valuable on the other. They contain substantial amount of metal value
· The relatively high cost for e-waste disposal in developed countries has driven recycling operations to developing countries such as China India and Pakistan (Figure 1 left). It is estimated that nearly 80 of all e-waste generated in developed countries is exported elsewhere.
This dwarfed the plastic scrap import volume of any other nation during that time span. The closest any nation came to even 1 million tons of plastic scrap imports in any one year was when the Netherlands imported nearly 687 000 tons in 2014 (and much of that scrap

· long time are often made of high-purity copper because of its excellent electrical conductivity. An electrical wire consists of a copper core covered with resign to provide insulation and corrosion resistance. The life of an electrical wire is mainly determined by the life of the outer covering(4) and the core can be recycled to copper material.

An additional concern is overuse of plastics and resulting plastic waste. Worldwide plastics and polymer consumption has grown at an average rate of 10 per year since the 1990s.17 Rates of increase are particularly large in low-income and middle-income economies. Approximately 275 million tonnes of plastic waste was generated in global coastal cities in 2010 with China contributing >25 of

Magnetic separation is one of the oldest forms of material separation and it has existed in the mineral processing industry since the early 1900s. It is a way to divide non-ferrous from ferr ous
Eddy current separation is based on the use of a high speed magnetic rotor system and is used to remove nonferrous metals (i.e. aluminum and copper) from waste plastic streams. Due to the high speed of the rotor an electric current called Eddy current is induced into conducting metals.

Recycling rate. The percentage of a commodity which is recycled. A higher recycling rate may reduce risk to supply. Substitutability. The availability of suitable substitutes for a given commodity. High = substitution not possible or very difficult. Medium = substitution is possible but there may be an economic and/or performance impact

Density measures the mass per unit volume is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm 3. The density of a plastic sample may change due to change in crystallinity loss of plasticizers absorption of solvent etc. It is important to note that density varies with temperature. Therefore to determine the exact density of plastic it is

· There is a big waste generation nowadays due to the growing demand for innovation and the fact that more and more products have a reduced lifetime increasing the volume of dumps and landfills. Currently one of the segments of large volume is the technology waste which reflects on the printed circuit boards (PCBs) that are the basis of the electronics industry.
