Household garbage is typically collected at least once per week primarily due to the rapid decomposition of food waste.1

Regular collection is a critical component of solid-waste management because it helps protect public health and safety. When waste is left to accumulate, it can create conditions conducive to the breeding of rodents and insects, which may contribute to the spread of vector-borne diseases. Additionally, frequent removal helps prevent the development of offensive odours and minimizes the environmental risks associated with improper waste storage and disposal.123
