Design for Degradation

What are biodegradable materials?

• Substances that can only be broken down by human intervention

• Materials that cannot be broken down by natural processes

• Substances that release toxic substances when broken down

• Substances that can be broken down by natural processes into simpler, non-toxic substances over time.

How do biodegradable materials degrade in the environment?

• Biodegradable materials degrade through exposure to sunlight.

• Biodegradable materials degrade through the action of microorganisms.

• Biodegradable materials degrade through chemical reactions.

• Biodegradable materials degrade through physical breakdown.

What is the environmental impact of non-biodegradable materials?

• Non-biodegradable materials have no environmental impact.

• Non-biodegradable materials have a significant negative environmental impact.

• Non-biodegradable materials have a positive environmental impact.

• Non-biodegradable materials have a minimal environmental impact.

What are some examples of biodegradable materials?

• concrete, asphalt, PVC pipes, tires

• paper, cardboard, wood, food waste, certain types of plant-based plastics

• aluminum cans, rubber, synthetic fabrics, batteries

• glass, metal, plastic bags, Styrofoam

What are the benefits of using biodegradable materials?

• Biodegradable materials have several benefits, including reducing pollution and waste, conserving resources, and having a lower impact on ecosystems.

• Biodegradable materials are more expensive than non-biodegradable materials.

• Biodegradable materials are not as durable as non-biodegradable materials.

• Biodegradable materials are difficult to dispose of properly.

What are some recycling strategies for reducing waste?

• Dumping waste in landfills

• Separating recyclable materials, reusing items, composting organic waste, buying products made from recycled materials

• Burning waste in an incinerator

• Throwing all waste in the same bin

How does recycling help in sustainable product design?

• Recycling reduces the need for raw materials, conserves energy, and minimizes waste generation.

• Recycling only reduces the need for raw materials but has no impact on energy conservation or waste generation.

• Recycling has no impact on the need for raw materials, energy conservation, or waste generation.

• Recycling increases the need for raw materials, wastes energy, and maximizes waste generation.

What are the principles of sustainable product design?

• Reducing waste, using renewable materials, minimizing energy consumption, designing for durability and recyclability, considering the entire product lifecycle

• Increasing waste, using non-renewable materials, maximizing energy consumption, designing for obsolescence and disposability, ignoring the product lifecycle

• Promoting waste, using non-renewable materials, maximizing energy consumption, designing for fragility and non-recyclability, disregarding the product lifecycle

• Ignoring waste reduction, using non-renewable materials, maximizing energy consumption, designing for short lifespan and non-recyclability, neglecting the product lifecycle

What are the challenges in implementing sustainable product design?

• Difficulty in balancing environmental and economic factors

• Lack of available sustainable materials and manufacturing processes

• Balancing environmental, social, and economic factors, integrating sustainable materials and manufacturing processes, ensuring product durability and longevity, and overcoming cost and consumer perception barriers.

• Lack of consumer demand for sustainable products

How can individuals contribute to design for degradation?

• By using non-recyclable materials, increasing waste production, and promoting single-use products.

• By using sustainable materials, reducing waste, and promoting recycling and reuse.
