Waste statistics and recycling rates
Amount of waste
The Helsinki Metropolitan region and Kirkkonummi generated 645 000 tonnes of municipal solid waste (MSW) in the year 2020. This is 520 kg per capita. MSW is household waste and similar waste from the service sector.
Household waste produced in the Helsinki Metropolitan region amounted up to 346 000 tonnes, which is 280 kg per capita, in year 2020. This is 15 kg more per capita than the previos year. The household waste per capita have been slightly decreasing in the previous years, but an increase in both mixed waste and separately collected mixed was seen in 2020.
Every other year we produce statistics of other waste streams than MSW waste in the region. Most of the waste generated in the region is land masses from construction, which amounted to 78 % of all the waste generated in the region in year 2018. Waste from the other sectors were as follows; building construction waste 7 %, household waste 4 %, private service sector 4 %, energy sector 4 %, industry 1 % and other public sector 1 %. See waste produced by sector here (.xlsx).
Of the household waste generated in the Helsinki Metropolitan region and Kirkkonummi, 45 % in recycled. The rest is incinerated with energy recovery. Household waste do no longer end up in landfills. The calculation of the recycling rate takes into account the rejects from the recycling processes. The goal is to increase the recycling of household waste. This would require more effective and better sorting of the waste where is it is generated, so that more waste goes to recycling, and less waste to incineration.
The recycling rate of all municipal solid waste was 50 % in 2020. Less than 1 % went to landfills or other, and rest was incinerated with energy recovery. The recycling rate of all MSW is higher than that of households due to better sorting of biowaste in the private service sector.
Type of waste
Of the municipal solid waste is 44 % mixed waste. This means 230 kg per capita of mixed MSW.
Half of the household waste consists of mixed waste, which makes 136 kg per capita. Most of this waste could have been sorted, a big part of the mixed waste consists of biowaste and plastics. The mixed waste is incinerated with energy recovery, whereas the sorted waste mostly is recycled as material.

Household mixed waste composition
A household mixed waste composition study in the Helsinki metropolitan area is carried out every three years. The results are published as open data (in Finnish).
Over a third of the mixed waste consists of biowaste. According to the study in 2021, some 40 % of the total amount of mixed waste was biowaste, when including soft tissue paper.The majority, 80 %, of the mixed waste could have been recycled if sorted.
