Urban Waste Flashcards
What is waste
Non biodegradable products that are no longer being used
Why is global waste increasing
Population growth and increasing development throughout the world
More pop means more resources needed and then wasted
More development means more resources made and then wasted
Explain why globally urban residents in HICs produce more waste than rural inhabitants in LICS
HICS have access to more resources
They are often more developed and therefore have more resources to begin with to then waste
Products are not of as much value
LICS are less developed so do not use resources which can be wasted eg food
How do countries of diff incomes generate diff amounts of waste
Lower income- least waste- things are more valuable
High income- more waste
Low middle income (eg China) most waste- waste is probably why they are not high income
What is domestic waste
Enervated as a consequence of household activities- cooking cleaning etc- paper cardboard furniture
Categorised As biodegradable, recyclable or inert
Municipal waste
Results from municipal activities and services such as street cleaning
It includes dead animals, market waste and abandoned vehicles
Solid domestic and commercial waste
Commercial waste
From offices, wholesalers and trail stores, hotels etc
Categorised As biodegradable, recyclable or inert
Animal and vegetable waste
Resulting from handling storage sale cooking and serving food
Waste becomes putrid producing stronf smells attracting rats flies and other vermin
Req immediate attention in its storage handling and disposal
Institutional waste
From school unis hospitals and research institutions
Inc waste that is hazardous to public health and enviro
Ashes
Residue from burning of coal charcoal and stuff for heating and cooking in houses, institutional and small industry establishments
Ashes consist of fine powdery residue, often mixed w small pieces of glass and metal
When produced in large quantities these wastes are classified as industrial waste
Bulky waste
Domestic furniture, and ‘white goods’ , commercial and packaging and containers etc
Requires special collection
Street sweeping waste
Paper cardboard plastic dirty leaves veg matter
The mixed nature of waste usually makes separation of biodegradable, recyclable or inert uneconomic
Dead animals
Dead animals if not collected issue to public health as attract vermin and flies
Carcass and animal parts from slaughter houses are regarded as industrial waste
Construction and demolition waste
Consists mainly of Earth
Stones concrete brick timber
Roofing and heating systems
Plumbing etc
If not recycled it will make up sig part of landfill
Industrial waste
Can be anything
From food to coal to ash etc
Examples of biodegradable waste
Food and kitchen waste
Green waste
Newspapers
Eg of recyclable materials
Paper Cardboard Glass Bottles Tin cans Aluminium cans Metals Plastics Clothes Tyres
Eg of Inert waste( will not decompose)
Waste clothing, drink cartons, plastic toys
Eg of electronic waste
Electrical appliances
Lightbulbs
Phones
Eg of Opposite waste (waste containing diff materials)
Construction and demolition waste
Eg of hazardous waste
Most paints
Chemicals
Tyres
Batteries
Pesticides
Herbicides
Fungicides
Eg of Biomedical waste
Expired medical drugs
What waste is more common in HIC
Food and electrical
What are waste streams
Journey of waste from its source (domestic commercial or industrial) to its disposal
Eg recycling burial etc
Name 9 waste streams
Recycling
Reusing
Reduction
Recovery
Incineration
Submergence
Trade in waste
Randomly dumped
Burial
What is recycling
Reusing materials by breaking them down and reproducing something
What is reusing
Using something again without breaking it down
What is reduction
Using less of materials eg companies using minimal packaging
What is recovery
Extraction of materials for a specific next use
Eg recycling
Compost
Energy regeneration
What is incineration
Burning waste materials- can generate electricity
What is submergence
Dumping waste in the ocean
What is trade in waste
Trading waste eg to firms to make goods
What is randomly dumped
Illegal dumping
What is burial
Landfill
Which is most sustainable waste stream
Reducing
Which is least sustainable waste streams
Randomly dumped
Burial
