Approximately one million tons of waste is generated in the Helsinki metropolitan area each year, with over half of this waste being used again in some capacity. In future, waste that cannot be recycled will be used in energy production, resulting in a significant increase in the utilisation of waste.
In the Helsinki metropolitan area, waste management involves sorting either at source, in local collection centres or in sorting facilities. Enterprises with the necessary permits collect hazardous waste of both households and companies. Recycling of paper, cardboard, metal, glass and biodegradable waste is organised, while unsorted waste is treated at landfill sites.
Efficient wastewater purification
All wastewater from the Helsinki metropolitan area is treated efficiently in modern treatment facilities then transported as newly clean water into the sea via a pipeline. The process is energy-efficient, with all by-products of the treatment also utilised efficiently.
Furthermore, Helsinki’s wastewater treatment facilities have received international recognition for their demonstration of top-ranking environmental understanding. Finnish authorities also closely monitor cleaning results and possible environmental effects.
