Study Notes
Material Selection and Recycling
- Freecycling: Recycling waste by giving it to others for free
- Deconstruction: A process of taking apart waste materials to recover raw materials
- Open-handed reuse: Recycling waste by giving it to others without needing to modify it or create a new product.
- Upcycling: Recycling goods to manufacture products of greater value.
Materials Properties
- Glass: A non-biodegradable material that can be recycled repeatedly without losing quality.
- Porcelain, Clay, and Metal are NOT necessarily non-biodegradable AND recyclable materials.
Materials Cycle Process
- The materials cycle involves Earth, Raw Materials, Synthesis, Processing, Manufacturing, Assembly, Engineered Materials, Product Design, Application, and Waste. The cycle repeats.
- Option c. represents the cycle properly.
Glass Composition
- Glass is primarily made of soda-lime, leaded, and borosilicate
- Alkaline is NOT a part of the composition of glass.
Recycling Purpose
- Recycling's purpose is to reuse waste products
- This is achieved through different methods including 'creative reuse'.
Recycling Techniques
- Recycling: A process that involves taking apart discarded items and separating them to recover raw materials.
- Freecycling: A method of recycling used to donate items to people who want them for free.
- Deconstruction: A recycling method used to break apart items and recover their raw materials.
Recycling Materials Substitutes
- Recycled materials can replace raw materials that are becoming scarce.
- Examples that are NOT substitutes include Geothermal heat, a form of energy.
Reuse Types
- Reuse: Re-using an item without modifying its shape or original nature.
- Downcycling: Recycling that results in a lower quality product or material.
- Recycling: Process of recovering raw materials from waste items to create something new.
Recycle Codes
- Polypropylene: 5
- High-density polyethylene: 2
- Polystyrene: 6
Adaptive Reuse
- Adaptive reuse: Process of repurposing buildings that have outlived their initial use.
Waste Sources
- Common sources of waste include packaging, junked automobiles, tires, and durable goods.
- Plastics, rubber, and styrofoam are common types of waste materials commonly coming from these sources.
Recycling Methods - Waste Hierarchy
- Reuse is the second best option in the waste hierarchy after recovery.
Materials Recycled
- Materials commonly recycled include iron and steel scrap, aluminum cans, and glass.
- Appellation (or naming) is not a typical material recycled.
Waste Applications
- Energy is an example of an application in the materials cycle.
Re-usable Materials
- Materials such as bottles and old clothes can often be reused.
- Detergents are not typically re-usable in this sense.
