A Wasteful World
5.1 Types of waste and its production
a) The differences between LICs' and HICs' waste production.
HICs produce more waste than LICs, due to:
o Consumer society
o Richer people, so more ability to buy more products and therefore generate
more waste.
20% of the world's people (who live in HICs) account for 86% of consumption of
the world's products
The poorest 20% consume only 1.3% of the world's products
Los Angeles, USA, produces about 1256kg of rubbish per person per year
Abidjan, on the Ivory Coast in Africa, generates only 200kg of rubbish per person
per year.
b) Greater wealth is a major contributor to increasing waste, especially in HICs.
Development of the consumer society in HICs due to the increase in wealth, which
leads to more packaging, and a `throw away' society.
c) Different types of domestic waste in HICs.
Plastics
Garden Waste
Paper & Board
Kitchen Waste (Food Waste)
Metals
Rubber, Leather & Textiles
Wood
Glass
5.2 Recycling and disposal of waste
