Biogas plant digestate for agricultural use
The purpose of the project is to upgrade the digestate from the Ämmässuo eco-industrial center's biogas plant directly for agricultural use. Currently, biowaste is digested in the biogas plant and then composted. This investment project enables the full utilization of the biogas plant's processing capacity, reducing the amount of waste requiring composting.
Project updates
Construction work for the project has begun rapidly and is progressing on schedule. The construction is progressing as planned, with the building works being completed, with handover in December 2024 (image above). At the same time, the machinery and piping installations continue according to the schedule.

Previous Events
The contractors have been selected, and the contracts have been signed.
HSY's Board decided on the implementation of the project in connection with the selection of contractors in February 2024.
In the context of the environmental permit amendment application, the project was defined as a so-called Green Transition project. Temporary priority has been given to the processing of permits for Green Transition projects in Regional State Administrative Agencies (AVI) during the years 2023–2026.
Project Summary
The HSY project to upgrade the biowaste digestate for agricultural use will increase renewable energy production at the biogas plant compared to the current level. At the same time, it will reduce the environmental impacts of biowaste treatment, such as odor and gas emissions, as the digested biowaste can be directly utilized as fertilizer, reducing the need for windrow composting and producing more mature compost. The nutrients and carbon contained in the biowaste will be recycled into farmers' fields as organic-certified recycled fertilizer.
Financing
The total estimated cost of the investment is €14.9 million. The Ministry of the Environment will support the project with €4.36 million.
Project timeline
Construction is scheduled to begin at the end of March 2024, with completion expected by the end of 2025.
