Week 5 Infrastructure and Sustainability Flashcards
What type of network is the storm water and wastewater treatment system?
Many to one
Collect from many sources, treat at one end point.
What is organic waste?
Waste which energy can be recovered from combustion.
e.g. food, timber, plastics
What is inorganic waste?
Waste that are difficult to decompose.
e.g. glass, metals, construction materials
What are the 4 most common waste management practices?
Reuse
Recycle
Bury (landfilling)
Burn
What is the hierarchy of solid waste management from best to worst.
Redesign
Reduce
Reuse
Recycle/compost
Recover energy
Treat and Dispose
Simplified:
Source reduction and reuse
Recycling and composting
Energy recovery
Treatment and disposal
How emissions can be mitigated by waste production and collection?
Producers : Avoid/reduce/reuse
Consumers: Reuse/recover/minimise disposal
What type of network is the transport system?
Many to many
Multiple origins, destinations, and routes.
What are the inherent vulnerabilities of the Transport system’s dependence on oil?
- Heavily reliant on petroleum products.
- Price volatility of oil.
Ways to mitigate emissions from transport.
- Improved efficiency: reduces fuel consumption and emission intensity.
- Reduced journeys: Reduce distance thus reducing fuel consumption.
- Shift to lower-carbon transport.
What are the main cause for energy use in buildings?
Heating and cooling
What affects the heating and cooling energy consumption amount?
- Climate: Temperature
- Materials: Insulation, conduction.
- Geometry: Size and shape of building.
What are common mitigation strategies for buildings?
- More energy efficient appliances.
- Using smart metering.
- Better building design.
- Material choice.
- Education (know to not use a stupid amount)
