All Flashcards
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 general steps of recycling?
Collection, processing, manufacturing into new products, and purchasing recycled products.
What are the steps of composting?
Collect organic waste, mix greens and browns, maintain moisture and aeration, allow decomposition, and use compost.
Describe the process of anaerobic digestion.
Organic waste is broken down by microorganisms in the absence of oxygen, producing biogas and digestate.
What are the steps in landfill bioreactor operation?
Waste is placed in the landfill, liquid is added to enhance decomposition, biogas is collected, and leachate is managed.
Describe the process of phytoremediation.
Plants absorb pollutants from soil or water, breaking them down or storing them in their tissues.
What are the steps in activated sludge process?
Wastewater is aerated, microbes consume organic matter, solids settle, and treated water is discharged.
Describe the process of waste incineration.
Waste is burned at high temperatures, reducing its volume and generating heat that can be used to produce electricity.
What are the steps in creating compost?
Collect organic waste, layer green and brown materials, maintain moisture and aeration, and allow decomposition.
What is the process of landfill capping?
Covering a landfill with a layer of impermeable material to prevent water infiltration and gas escape.
What is the process of leachate collection?
Installing a system to collect leachate from a landfill to prevent groundwater contamination.
What are the environmental consequences of increased waste generation?
Landfill capacity issues, pollution, greenhouse gas emissions, and resource depletion.
What are the effects of improper landfill management?
Groundwater contamination, methane emissions, and soil pollution.
How does recycling benefit the environment?
Saves natural resources, reduces energy use, and cuts down on landfill waste.
What is a potential environmental hazard associated with abandoned landfills?
Groundwater contamination from leachate.
What are the effects of methane emissions from landfills?
Contributes to global warming as a potent greenhouse gas.
What is the result of incineration of waste?
Reduces waste volume, but can release air pollutants if not properly managed.
What is the impact of plastic pollution on the environment?
Harms wildlife, pollutes oceans, and persists for long periods.
What is the effect of composting on soil quality?
Improves soil structure, fertility, and water retention.
What is the effect of deforestation on waste management?
Reduces the availability of natural resources for recycling and increases waste generation.
What are the effects of improper disposal of electronic waste?
Releases toxic chemicals, such as lead and mercury, into the environment.
