“Technology is people using resources such as ideas, information, skills, materials, tools & equipment and energy.”1. It is this use of resources by designers which is the focus for this assessment. As design does not occur in a vacuum it is the designers obligation to ensure that his or her use of various resources is appropriate. There are many issues which relate to design and technology, such as; Who benefits from technological enterprises? Whether short-term gains are made with little regard to long term costs through new technologies

“Design and Technology involves the use of resources and energy to make products, systems or environments. Costs need to be considered as part of designing. Design does not occur in a vacuum; it always occurs in a social context, and there will be an impact of some sort on this society or group. Designers therefore need to be aware of the context in which they are designing and to take into account the impact their designs will have. “The result of any design activity will also be a reflection of the designer. Attitudes, background, values and even beliefs will have an effect on the design process. It is important to be aware, as a designer, of how these factors affect your design activity.”2 This quote from our textbook (studies in senior design and technology) outlines the importance of the designer taking an interest in the ramifications that his design may have on society and the environment 1

Aluminium is the most abundant metal on earth and it is used in many things ranging from automobiles to soft drink cans. Aluminium is considered an exhaustible resource because it takes longer than a human life to form, despite this aluminium is very easy to recycle making it a sustainable resource if it is managed correctly. Aluminium offers great strength for its weight and when aluminium is mixed with other metals the result can be an alloy which is as tough as steel. Aluminium comes from bauxite, which is a clay-like substance, which is found in tropical soil. Aluminium is a relatively new metal as it takes large amounts of electricity to refine bauxite into Aluminium, and large amounts of electricity have only been available since the beginning of the 20th century. Due to aluminium's nature it is very easy to recycle, this means that through recycling the cost of aluminium can be reduced through no mining being required to supply the basic material. The ease of which Aluminium can be recycled has made it a very lucrative business generating more than $1 billion a year in Australia alone.The recycling of Aluminium takes only a twentieth of the energy required to produce it from bauxite making it effectively twenty times more cost effective. The recyclability of Aluminium has meant that it is used in many different ways such as for drink cans, car parts and food containers. In Australia there is wide public acceptance of the recyclability of Aluminium and currently over 50% of Australia's aluminium cans are recycled by recycling schemes of the Alcoa and Comalco companies. Due to the environmental problems associated with the industrial revolution aluminium has recently become one of the more attractive resources in the world due to the minimal impact its production has on the environment. This is due to its recyclability, this recyclability greatly reduces the amount of energy required to produce aluminium. This reduction in energy consumption reduces the amounts of harsh pollutants such as carbon dioxide and nitrogen oxide which are released from power stations in the production process. With the recycling of aluminium the impact on the environment is minimised because no mining is required. Page 61 of 65

Throughout most of the developed world aluminium recycling is being implemented. On a global scale many Conservation groups, multi-national companies and governments actively encourage the use of aluminium as a recyclable resource. Some governments and companies have created campaigns to encourage the recycling of aluminium, some even pay the public to collect aluminium such as through the Cash-a-Can program. These programs not only reduce the environmental impact of the use of aluminium but also provide a lucrative business for aluminium producers. Due to the many attractive features of using aluminium there has been a noticeable increase in the worlds consumption of aluminium, especially through aluminium recycling, this has mainly been due to public education about the rewards of using and recycling aluminium as a way to decrease pollution as well as aluminiums many other attractive aspects. In most developed countries the use of recycled aluminium has been recognised for the benefits it has on the environment as well as the economic benefits it provides.

Ethical Issues The three ethical issues that I will discuss are as follow: 1- . 2-. 3-.
