Only a few millimeters thick, they provide hours of entertainment and hold huge volumes of information. By learning about product life cycles, you can find out how to reduce the environ- mental impacts and natural resource use associated with products you use every day.

When you understand these con- nections, you can make better environmental choices about the products you use, and how you dispose of them. Follow the life cycle of a CD or DVD on this poster to learn more about how these products are made and how you can help reduce their environmental impacts.

Materials Processing ifuct A f The entire process of stamping a CD with digital information takes between 5 and 10 seconds. Materials Acquisition CDs and DVDs are made from many different materials, each of which has its own separate life cycle involving ener- gy use and waste.

Bauxite ore is the main source of aluminum and is extracted from the Earth. Alumina is then turned into aluminum through a process called "smelting. Polycarbonate is melted and put in a mold.

With several tons of pressure, a stamper embeds tiny indentations, or pits, with digital infor- mation into the plastic mold. Bythis number ffi Every month approxi- matelypounds of CDs become obsolete outdated, useless, or unwanted. Purchasing Decisions You constantly make decisions about buying products.

One of your decisions probably involves weighing how much y want a product against how much it costs.

You might also want to consider whether the information you think you need on disc is actually available on the Internet. If it is, you; might not need to buy the disc at all!

Thinking about these issues will make you a more informed consumer and will help you make decisions that help to protect and preserve our environment.

Product Life Cycle of Compact Disc Introduction: Compact disc technology is one of the fastest growing industries of all time. Compact discs became popular in the early 80’s due to its ability to offer increased audio performance over . A jewel CD case is a compact disc case that has been used since the compact disc was first released in It is a three-piece plastic case, measuring by by 10 millimetres ( in × in × in), a volume of cubic centimetres ( cu in), which usually contains a compact disc along with the liner notes and a back card.. Two opposing transparent halves are hinged. Abstract:This poster depicts the life cycle of a CD or DVD from obtaining raw materials through manufacture, packaging, distribution, useful life, and vetconnexx.com explains the importance of life cycle management and encourages reuse and recycling. The poster also includes crafts and other ways to reuse CDs and DVDs.

Designing for the Environment For a product to come into existence, it must be designed. And that design can have as much of an impact on the envi- ronment as any other step in a products life cycle.

For example, designers can plan for a product to be easily made from recycled materials, thus reducing the need to mine or gather raw materials.

Most industries, including high-tech industries, have developed voluntary standards that many manufacturers fol- low when designing and manufacturing new products.

These standards help make products as environmentally sound as is technologically possible. These standards also change as rapidly developing new technologies become available. Screen printing involves the use of many materials, including stencils, queegees, and inks.

CDs and DVDs are created with materials that are extremely stable. Certain conditions, such as high humidity, or extended periods of high temperatures, rapid temperature changes, and expo- sure to certain types of light, can damage discs and shorten their useful life.

Taking care of your discs by keeping them out of direct sunlight and away from heat and water will help them last longer. Transportation by plane, truck, or rail requires the use of fossil fuels for ener- gy, which contribute to climate change.

This packaging can be made from recycled or raw materials. For example, the plastic used can be from recycled bottles or from crude oil and natural gas extracted from the Earth and combined with chemicals.

The general life cycle of a CD/DVD starts with the mining of raw materials (aluminum, gold, nickel, etc), the elements are then smelted and processed. This process is very energy intensive and produces large amounts of wastes.

A bicycle, also called a cycle or bike, is a human-powered or motor-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other.A bicycle rider is called a cyclist, or bicyclist.. Bicycles were introduced in the late 19th century in Europe, and by the early 21st century, more than 1 billion were in existence at a given time.
