PRODUCT LIFE CYCLES

Article 3.3.3 of ISO 14001 defines what a life cycle is. Life cycles cover all the stages of a product, from the raw material acquisition to the end of usability and disposal. This concept applies particularly well to manufactured products and Life Cycle Assessment (LCA). Here is an example of a product life cycle:

Product Life Cycle - Environment

5 Product Life Cycle Phases

On the above Möbius strip recycling symbol, you can see the following five broad product life cycle phases:

1. Acquisition of raw materials to develop and manufacture a product;

2. Design stage, where a prototype will have its final shape, functionalities, and options;

3. Production or manufacturing. It ranges from small scale to mass production and includes the transportation and delivery of the products to the consumers;

4. Use by consumers, including product repair and reuse;

5. End-of-life which covers:

a. The final disposal of the product by the consumers;

b. Its collection by recycling facilities;

c. The recycling and materials recovery; 

d. The valorization to the waste (as energy, etc.); and

e. The final waste into landfills. 

The environment plays a central role in the product life cycle since it provides natural resources (water, air, minerals, wood, etc.) and energy to the five stages. The industry tends to economize, reuse and recycle natural resources and energy to improve efficiency and alleviate the weight on the environment.

Environment and production

Life Cycle of Electrical and Electronic Equipment

In electronics, various environmental requirements control different stages of devices life cycles. Their goal is to lower the impact on the environment. Here are some examples:

Life Cycle Stages of Electronic Devices Examples of Environmental Aspects Examples of Standards or Regulations
1. Acquisition of raw materials Consumption of heavy metals, hazardous substances, minerals (tin, gold, etc.), and other natural resources

Substances Restrictions

Conflict Minerals

2. Design Development of hardware (made of various materials) and energy-related products Ecodesign
3. Production, transportation, delivery Consumption of energy (factory, trucks, etc.) and consumable materials (solder on assembly lines, packaging, etc.) Regulations on emissions to the air, the soil, water, etc. ISO 14001 can help manage these requirements.
4. Use Consumption of energy to use the device Product Energy Efficiency as defined during ecodesign.
5. End-of-life, treatment, and final disposal Consumption of energy (recycling facilities, transportation), production of hazardous waste, e-waste WEEE

A manufacturer of electronic equipment developing a product life cycle approach may particularly pay attention to these requirements:

Ecodesign

Ecodesign Repair electronics

The ecodesign consists in considering environmental aspects when imagining and developing a new product prototype.

Some ecodesign regulations and other requirements apply to electrical and electronic products. For example, designers must strive to make products easy to repair and recycle. They avoid hazardous chemicals and foster materials that other applications can easily reuse. Consumers can replace spare parts without changing the whole unit. They can update software without upgrading the product, etc.

Ecodesign supports a circular economy approach, where the waste of an industry becomes the resource for another.

Product Energy Efficiency

Ecodesign motors

Eco designers aim at making their products as energy-efficient as possible. As a result, users will enjoy low-consumption devices from standby to full power modes. Less energy consumption means fewer costs for the user and potentially fewer gas emissions per product when the energy comes from non-renewable energy.

WEEE

Because of hazardous substances, waste of electrical and electronic equipment (WEEE) requires specific treatment. Recyclers must sort WEEE in separate channels from other consumer waste like papers, plastics, or food residues. 

Environmentally sound WEEE treatment can reveal complex and costly. Laws in various countries attempt to finance and organize the collection of WEEE. Notably, Europe and North America have implemented e-waste regulations in this regard. Nevertheless, most WEEE is still not recycled appropriately.

Waste of Electrical and Electronic Equipment

Life Cycle Assessment

Life Cycle Assessment (LCA) is a method that allows the evaluation of the potential environmental and social impacts of products life cycles. Considering the product life cycles aspects above will help you better conduct life cycles.
