Every apartment association or individual household has to enter into a waste
management contract with a waste transport company. Waste containers must be
emptied often enough to avoid overfilling and the emergence of bad odours and
pests. Pursuant to the Waste Act, containers in densely populated areas must be
emptied at least once a month. This is why a container of suitable size that
corresponds to the quantity of waste created must be selected (residential
houses are permitted to use bin bags).
