All Flashcards
How can source reduction promote sustainability?
By minimizing the amount of material used, reducing resource consumption and waste generation.
How can reuse contribute to sustainability?
Reduces the need for new products, conserving resources and energy.
How does composting support sustainable agriculture?
By producing nutrient-rich soil, reducing the need for chemical fertilizers.
How can green procurement help protect the environment?
By promoting the purchase of eco-friendly products and reducing packaging waste.
How can waste-to-energy policies promote sustainability?
By converting waste into energy, reducing reliance on fossil fuels.
How can recycling mandates promote sustainability?
By increasing recycling rates and reducing landfill waste.
How can education and awareness promote sustainability?
By informing people about waste reduction methods and encouraging responsible waste management practices.
How can product take-back programs promote sustainability?
By ensuring that manufacturers are responsible for their products' waste, encouraging them to design products that are easier to recycle or reuse.
How can anaerobic digestion promote sustainability?
By converting waste into biogas, a renewable energy source, and reducing greenhouse gas emissions.
How can bioremediation promote sustainability?
By using microbes to break down pollutants, reducing the need for more invasive and costly cleanup methods.
What is Source Reduction?
Designing products to use less material, reducing waste at the source.
What is Reuse?
Using items more than once, finding new uses for old items.
What is Recycling?
Turning old materials into new products, giving materials a second life.
What is Composting?
Turning organic waste into nutrient-rich soil.
What is Green Procurement?
Buying eco-friendly products with recycled materials and less packaging.
What is Aerobic Treatment?
Using oxygen-loving microbes to break down organic waste.
What is Anaerobic Treatment?
Using microbes that don't need oxygen to break down organic waste.
What is Phytoremediation?
Using plants to clean up soil and water.
What is Extended Producer Responsibility (EPR)?
Manufacturers are responsible for managing their products' waste.
What is Pay-As-You-Throw (PAYT)?
A waste disposal system where residents pay based on the amount of waste they generate.
What is the waste management hierarchy?
Reduce > Reuse > Recycle; prioritizing waste prevention.
Why is source reduction the most effective waste reduction method?
It minimizes the amount of material entering the waste stream initially.
How do recycling and reuse contribute to a sustainable future?
They conserve resources and reduce environmental impact.
How does biological treatment reduce waste volume?
Microorganisms decompose organic waste, reducing its mass.
What is the goal of Zero Waste policies?
To eliminate landfill waste through reduction, reuse, and recycling.
What is the significance of waste segregation?
Waste segregation is important to ensure that different types of waste are treated appropriately.
What are the benefits of anaerobic digestion?
Converts waste into biogas, a renewable energy source.
Why is safe packaging important for radioactive materials?
To prevent radiation exposure during transport.
What is the difference between low-level and high-level radioactive waste?
High-level waste is more dangerous and requires long-term storage.
What is the circular economy?
An economic system aimed at eliminating waste and pollution, keeping products and materials in use, and regenerating natural systems.
