Design affects repair and material recovery. Actual impacts also depend on use, spare-part supply and waste services. Subject: Design & Technology · Area: Designing & Making · Ages 15 to 16 Page: https://lightmysky.com/learn/design-and-technology/the-whole-life-of-a-product-mt_hyBZiDvDoX ## Ready when they can - List the main stages of a product's life from raw-material supply to end-of-life handling - Name a design choice that helps safe access to a worn part and explain why suitable spares also matter - Explain why joined materials may need separating before recycling - Describe evidence of repair barriers, distinguish it from proof of intent, and name evidence that tests a repairability claim ## Lesson: Follow a product's whole life You have compared ways to make one item or many copies. Now follow a product beyond manufacture. A useful life-cycle model has four main stages: raw-material supply, manufacture, use and end of life. Transport can occur between stages. Materials and energy are used across the life cycle. The stage with the greatest environmental impact depends on the product and its use. *(drawing: End-of-life handling can include material recovery or disposal. Recovered material can enter another product's life cycle.)* **Example.** Follow an oil-based plastic straw. Extracted oil is processed to make plastic, then the plastic is shaped into a straw. After use, the route depends on local waste services. Acceptance of a plastic type does not mean every small object made from it can be sorted. Ordinary plastic straws can remain as waste or break into smaller pieces. Litter reaching water is environmental leakage, not a planned disposal route. Repair needs safe access to a worn part, a suitable replacement and a way to fit it. Standard screws can help a case open without damage. Available spares and repair information also matter. A glued case can hinder access, but no single feature proves every repair is possible. Design affects repairability; later spare-part supply and repair services affect it too. Electrical repairs may need a qualified person. Joined materials may need separating before recycling. Glue bonding metal to plastic can make separation harder. Battery types have different chemistries and collection rules. Ask an adult to check local instructions and an accepting service. Used lithium-ion batteries can cause fires in waste systems. Keep them out of general rubbish and household recycling bins. Do not open a battery or pry it from a device. Hold a product's making and end-of-life impacts fixed. Keeping it useful for ten years instead of two spreads that same total over more years, lowering its share per useful year. This does not prove every repair lowers total impact. Repair materials, operating energy and safety also matter. Compare options that provide the same service over the same period. A sealed case and unavailable spares show repair barriers. They do not prove the maker wanted early failure. Check repair information, spare-part supply and price, and safe access to the worn part. A qualified person's successful repair using an available spare tests repairability more directly than an advert. That test concerns the part repaired; it does not prove every future fault can be fixed. **Recap.** Follow the life cycle, check repair and recycling barriers, and compare the same useful service. Evidence of a repair barrier does not prove a maker's intention. *Lesson, questions and flashcards written for this dataset about product life cycles, repairability and material recovery.* ## Practice 8 questions on this page, each with its working shown. ## Needs first - [Finite Resources & Recycling](https://lightmysky.com/learn/science/finite-resources-and-recycling-mt_0e5rZxbAeR) - [Making One, Making Thousands](https://lightmysky.com/learn/design-and-technology/making-one-making-thousands-mt_0wbzsY10cQ) ## Optional connections - [Systems: Input, Process, Output](https://lightmysky.com/learn/design-and-technology/systems-input-process-output-mt_bMNTQ-3a_u) - [Designing for the People Who Use It](https://lightmysky.com/learn/design-and-technology/designing-for-the-people-who-use-it-mt_QPznzhuBNI)
