Design for Environment - Assignment Example Also the regulations for environmentally friendly cars, the improvements in design of these green cars, the emission characteristics have been discussed. I. Recyclable household items: According to an article by Kat Long (2010), the most commonly recyclable house hold items are paper , cardboard, plastic, metals, glass, E- wastes, printer cartridges and batteries. Plastics: Recycling of plastic wastes has become a prime concern due to poor biodegradability of the materials used. According to Achilias.D. et al (2008), â€Å"Polyolefins (LDPE, HDPE, PP) are a major type of thermoplastic used throughout the world in such applications as bags, toys, containers, pipes (LDPE), houswares, industrial wrappings and film, gas pipes (HDPE), film, battery cases, automotive parts, electrical components (PP).† While the condensation polymers can be easily recycled, the addition polymers like PET (Poly Ethylene Terephthalate) are difficult to recycle (Karayannidis and Achilias, 2007). Achili as and Karayannidis (2004), propose a thermochemical recycling called pyrolysis that produce liquid form like gasoline. Sustained Plastic waste management involves the mechanical or chemical methods in which the polypropylene and polyethylenes are converted into useful end products. In mechanical recycling, the polymer is dissolved in a solvent and is separated. Achilias.D. et al (2008) claim that the polymer recovery can be greater than 90% by the choice of proper solvents. The end product quality has been examined by Fourier Transform – Infra Red (FTIR) and Differential Scanning Calorimetry (DSC). The end products of these recycling methods include hydrocarbon gases and oils, which can be again reused as feedstock in petrochemical plants. E – waste: E wastes are primarily the old unused computers, cell phones and other electronic gadgets. In the official website of Apple, ( iMac and the environment, ) , it is stated that the challenging task faced by the computer ind ustry with respect to environmentally friendly design is the use of materials involving mercury, arsenic, phthalates, brominated flame retardants (BFRs), PVC in their products and copper wires. The first E-waste recycling was introduced in Switzerland and later followed by the European Union with the â€Å"Waste Electrical and Electronic Equipment Directive† (WEEE Directive, 2002/96/EC). One crude method of recycling the wires include burning the wires together to extract copper from them. Researchers say that these crude methods may lead to more contamination of air, soil and water. This drives the manufacturers of electronic goods to opt for environmentally friendly materials like mercury free backlighting and display glasses that are free from arsenic. Also choosing materials that are thinner, smaller and lighter enables lesser materials to be used. This reduced usage of materials leads to lesser green gas emissions. (The story behind Apple’s environment footprint, www.apple.com/environment/ ). The manufacturers also undertake a complete life cycle assessment of the product with respect to environmental factors. They also use hybrid methods that save energy by reducing the consumption of energy. For example, Apple proposes three techniques for reduced energy consumption. They are efficient power supply, proper power management and using low

Independent research into retailing of (lace wigs) Lacehairwigs.co.uk Essay

Independent research into retailing of (lace wigs) Lacehairwigs.co.uk - Essay Example They have earned the reputation of been more realistic looking and less detectable. To attach the wig to wearer, they are glued to the head scalp and are long lasting. They are resistant to various climatic conditions thus the wearer can swim, shower as well as engage in other activities without causing damage to the wig. Although the lace wig may seem a new idea, it has existed for a very long time now. It was first invented in France by Leguet in the early 19th century (Institute of Textile Technology, 1994). However the patent rights holder of the lace wig is Telier who, after long court battles with other wig creators, won the patents rights custody. Some cultures have embraced wigs so as to protect bald heads from the ultra violet rays of the sun. The European counties embraced a different approach in dealing with wigs. Wigs were worn simply to boost people’s status in the society. In some contemporary societies, wigs are worn as a symbol of respect and mainly found on official proceedings like court cases (Lhboutique, 2010). The lace wigs have been in use for quite a long period now. They have been used by the health practitioners, artists in the entertainment industry, kings, the young as well as the elderly. They have been used for various reasons like health problems, ornamental and others just for fun. In the past the lace wig was mainly worn for prestige as it was expensive thus could not be afforded from the low income earners. The lace wigs have also been worn by people for criminal reasons as the wig creates a new look for the wearer. In the contemporary society, wigs are worn by a range of people all with different motives which range from ornamental to criminal activities. The modern man has resorted to wearing wigs, and in particular the lace wig, instead of natural hair for various reasons. One of the reasons for doing this is health problems especially among cancer patients. Cancer treatment through chemotherapy and radiotherapy
