Applicability of ISWM
Integrated solid waste management can be planned for big or medium-sized cities. Although the principles used are the same, some of the waste system elements are more applicable in particular sized communities as shown in Table 11.1.
Table 11.1 Applicability of waste management components in different sized cites
|Waste management component||Big cities (population above 200,000)||Medium cities (population 100,000–200,000)||Small cities (population less than 100,000)|
|Reduction at source||Highly applicable||Highly applicable||Highly applicable|
|Sorting at household level||
Applicable, if the cities are close enough to manufacturers willing to take the materials recovered.
Applicable, sorting would probably be limited to separating compostable wastes.
|Reuse of items||Highly applicable||Highly applicable||Highly applicable|
Applicable if linked to big cities
Can be promoted through small-scale recycling (paper for example)
|Applicable and can be promoted through small-scale recycling (paper for example)|
Applicable and can be scaled up at material-processing and energy-recovery facilities
Can be scaled up by using the private sector/small-scale enterprises with subsidy
|Applicable and can be scaled up by using the private sector/ small-scale enterprises with subsidy||Applicable and can be scaled up by creating awareness and by organising small-scale enterprises|
