Life-cycle Analysis

A life-cycle analysis is a tool to identify, measure, and inventory the full range of impacts associated with inputs and outputs of raw materials, energy, labor, and waste during a product, service, or policy's life. The life-cycle includes production/manufacturing, distribution, use, and disposal.

As we know from the First Law of Thermodynamics, matter can neither be created nor destroyed, so any waste in the life-cycle (whether discarded, recycled, reused, or used in regeneration) must be considered in a life-cycle analysis. Waste and other output can have social, economic, and environmental impacts on current and future generations.

Interrelationships and Sustainability

By looking at the interrelationships between society, economics, and the environment as inputs and outputs in a life-cycle analysis, one can make connections between a product's life-cycle and the sustainability of its design. Sustainability can be defined as the ability to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Student Activity

In this activity, students will create a life-cycle analysis of a sneaker. From the trees that provided the rubber to the gas the shipping truck ran on, we will uncover each element required to produce one pair of shoes. We will discuss the pros and cons of each element, thinking of new, innovative design approaches along the way.

In groups, students will begin to design their own sustainable sneakers, taking into account all aspects of the life-cycle. Each part of the sneaker will be labeled and the life-cycle web of the new sustainable shoe will be drawn.
