Flashcards based on the implications of wider issues in design and technology, focusing on lifecycle assessments, environmental impacts, and material sourcing.

What is Lifecycle Assessment (LCA)?

LCA analyzes and evaluates the economic impact of a product through all stages of its life, from initial extraction to final disposal or recycling.

What are the stages evaluated in a Lifecycle Assessment?

Acquisition of raw materials, transporting materials, processing materials, manufacturing, using the product, and disposal or recycling.

What environmental issue is associated with the extraction of crude oil?

The extraction of crude oil causes greenhouse gases and harms habitats.

What material can be produced from polymers?

Polyethylene Terephthalate (PET) bottles are made from polymer pellets derived from crude oil.

What is the ecological footprint?

The ecological footprint measures the impact we have on the environment and natural resources.

What is the social footprint?

The social footprint refers to the impact we have on other people.

What key environmental issue arises from the tanning of leather?

Tanning produces toxins and causes pollution.

What is planned obsolescence?

The process of designing a product to go out of fashion or no longer function after a specific time period.

What impacts can the use of coal, gas, and oil have?

Air pollution, including greenhouse gases, and limited resources.

What are biopolymers sourced from?

Renewable feedstocks such as corn, potatoes, rice, palm, and wood.
