All Flashcards
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 are the effects of increased waste generation?
Increased landfill volume, environmental pollution, resource depletion.
What are the effects of recycling?
Saves natural resources, reduces energy use, cuts down on landfill waste.
What are the effects of using single-use plastics?
Increased plastic waste, pollution of oceans, harm to wildlife.
What are the effects of landfilling organic waste?
Methane emissions, leachate production, wasted resource potential.
What are the effects of improper disposal of radioactive waste?
Environmental contamination, health hazards, long-term ecological damage.
What is the effect of implementing a PAYT system?
Incentivizes waste reduction and recycling by charging residents based on waste volume.
What are the steps in recycling?
Collection, processing, manufacturing into new products.
What are the general steps in composting?
Collect organic waste, mix with bulking agents, maintain moisture and aeration, allow decomposition, and use the compost.
What are the steps in anaerobic digestion?
Collection of organic waste, digestion by microbes without oxygen, biogas production, and digestate use.
What is the process of landfill bioreactor operation?
Waste is placed in the landfill, liquid is added to enhance decomposition, biogas is collected, and leachate is managed.
