The objective of the biomass mapping was to create an overall image of Espoo’s biomass types. In addition to cooperation within the city, it is also important to develop the utilisation of biomass with other cities and private operators.

In 2021, the first city-wide biomass mapping was carried out in Espoo, which examined the quantities of biomass produced or processed in the City of Espoo, its processing sites and processes as well as reasoned proposals for the use of different biomass types, taking into account the circular economy, the city’s business perspectives and the possibility for companies to make use of biomass useless to the city.

The objective of the biomass mapping was to create an overall image of Espoo’s biomass types. This is the first biomass mapping carried out for the City of Espoo and it took into consideration an extensive whole.

The biomass types identified in the mapping are divided into municipal waste management biomass types and mass types within the market-based waste management services. The municipal waste management includes sewage sludge, garden waste and biowaste. Other biomass types include, for example, market-based biowaste, horse manure, forest and field side streams and common reed produced by private operators. Currently, biomass is used in Espoo to produce biogas and compost, and energy is generated by burning wood.

Utilisation of the biomass potential requires involvement of the city and private operators

In addition to the current situation, the mapping also looked into new types of processing for some biomass types. Espoo’s biomass mapping identified additional potential for utilising biomass in the production of soil, biogas and biocarbon as well as in new uses for common reed and grit used on roads. The City of Espoo plays a major role in harnessing the potential to enable better circulation of materials. In addition to cooperation within the city, it is also important to develop the utilisation of biomass with other cities and private operators in the Helsinki Metropolitan Area.

Espoo’s biomass mapping was carried out as part of the 6Aika KIEPPI (Partnership model for sustainable neighbourhoods) project. You can contact Mia Johansson to receive the written report (in Finnish).
