The frequency of waste collection by external stakeholders greatly influences the waste collection cost. The frequency of waste collection largely depends on a number of factors such as:
- quantity of waste
- rate of generation
- characteristic of waste
- density and type of housing
- availability of space with in the premises
- size and type of storage facilities
- attitude of generators
- available resources
Decomposition of organic/putrescible materials in solid waste causes aesthetic problems and thus demands more frequent removal, particularly for individual collection system. More frequent collection is required in sub-tropical and tropical climates as decomposition proceeds more rapidly in tropical climates than in the temperature climates.
Individual containers with well-fitted lids placed on the premises but outside the house do not demand frequent collection even in tropical climates. Storage containers placed within the kitchen require more frequent collection, however. Organic/putrescible materials also serve as a breeding ground of files, though it takes about seven days to reach maturation even in tropical countries, and therefor it does not have a significant influence on the frequency of collection may be necessary in the case of block/kerbside system to improve convenience of waste handling for generators and collection crews.
