What is degradation?
What is degradation?
Degradation is the process by which a material loses its properties over time due to exposure to environmental factors.
How does degradation contribute to waste generation?
How does degradation contribute to waste generation?
Highly degradable materials require frequent repairs or replacements, leading to waste generation.
Why is strength important for durability?
Why is strength important for durability?
Strength is critical for durability as materials/products with higher strength are less likely to break under external forces.

Study Notes
Durability
Durability refers to the ability of a material, product, or system to withstand wear, tear, and damage over time. It is important because it ensures products can last longer, reducing waste and minimizing costs associated with replacement. There are several aspects related to durability, including environmental impact, longevity, degradation, strength, and recyclability.
Environmental Impact
The selection of durable materials plays a significant role in reducing the environmental footprint. For example, materials like polypropylene and high-density polyethylene have excellent durability characteristics and can last for years or even decades without degradation. Not only do these materials reduce waste by lasting longer, but their durability also reduces the carbon footprint associated with manufacturing new products more frequently.
Longevity
Longevity refers to the period a material or product can maintain its functionality without replacement. For instance, using durable materials like glass fiber reinforced polymers (GFRP) allows structures to last longer than traditional concrete or steel structures. This longevity extends beyond the construction industry; composite materials used in automotive applications exhibit excellent resistance to wear and corrosion, resulting in longer lasting vehicles.
Degradation
Degradation is the process by which a material loses its properties over time due to exposure to environmental factors such as UV radiation, moisture, temperature changes, and mechanical stress. Highly degradable materials require frequent repairs or replacements, contributing to waste generation and resource consumption. Research and development efforts focus on improving durability by designing materials and products that can resist degradation, thereby extending their lifespan.
Strength
Strength is a critical factor influencing durability. Materials or products with higher strength are less likely to break under external forces, reducing the likelihood of costly maintenance and repair work. For example, ceramic materials often demonstrate superior durability compared to other types of materials due to their high hardness, stiffness, and toughness.
Recyclability
Recyclable materials offer another dimension to durability. As these materials can be recovered at end of life and reused in new products, they reduce the demand for virgin resources and extend their carbon footprint. Examples of recyclable materials include aluminum, paper, and glass.
In conclusion, durability is a vital aspect of product lifecycle management, with significant implications for environmental impact, longevity, degradation, strength, and recyclability. By selecting and designing durable materials and products, we can minimize waste, reduce resource consumption, and contribute to a more sustainable future.
