Collection intervals

Waste bins at properties with property-specific waste collection must be emptied at regular intervals to prevent odours or other harm, for example, being caused to the waste collection company. The maximum intervals are as follows:

• energy waste: 26 weeks (the obligation to sort energy waste will end between October 2023 and June 2024)
• mixed waste, if the property has a separate bin for biowaste or if biowaste (food waste) is composted: 16 weeks (12 weeks after the collection of energy waste has ended)
• mixed waste: 4 weeks
• biowaste on properties with fewer than 5 households: 2 (summer period 1 May–31 August), 4 (winter period 1 September–30 April)
• biowaste on properties with 5 or more households: 2
• biowaste: if the waste is stored in a container with a mechanical cooling system or if the container is located partly underground: 4 weeks
• carton packaging:  26 weeks
• metal packaging: 26 weeks
• glass packaging: 26 weeks
• plastic packaging: 26 weeks

Prolonging the collection interval of mixed waste

If you want your mixed waste collected at an interval of longer than 16 weeks, you must submit an application to the Lahti Region Waste Management Authority in writing at lahti.fi/jatehuoltoviranomainen. The maximum collection interval permitted is 26 weeks.
