New sensors provide information on the environmental impact of the MORE area
We have installed the first environmental sensors at the Karanoja circular economy area to help us map the area’s environmental impact. The data from the sensors we have developed will help us promote the sustainability and responsibility of the area and lay the foundation for the environmental certification of the MORE industrial zone in Hämeenlinna.
To develop suitable sensors, we first identified two key environmental monitoring targets: runoff emissions entering the Karanoja stream and the gas emissions from the landfill. The sensors, which were acquired for the area in collaboration with Kiertokapula Oy and Linnan Kehitys Oy, are specifically designed to meet the needs of the area, developed and built by Senior Research Engineer Gert Hattingh from Häme University of Applied Sciences.
The sensors placed in the Karanoja stream will measure the water temperature and electrical conductivity. These values help us track changes in the levels of nutrients, salts and dissolved solids in the water. We will compare the values measured at different points in the stream to get a better understanding of any runoff emissions caused by activities within the area.
For the landfill, we developed a methodology to measure the concentrations of gases that volatize into the air. Methane, carbon dioxide and other organic gases released from the soil are significant greenhouse gases. Monitoring these emissions is an important part of mitigating the greenhouse effect that is warming our atmosphere, especially in waste management sites where such gases are produced as organic waste break down. The new sensors will allow us to monitor emission levels and their evolution more continuously than before.
The data collected by our sensors provides us with more information about emissions generated in the area, enabling us to assess the environmental impact of the area more accurately. We use environmental data to support the responsible and sustainable development of the MORE industrial zone and to lay the foundation for environmental certification of the area.

Our project, co-funded by the European Union, is now running until July 2026 and is expected to bring significant improvements to the MORE region’s circular economy activities and environmental impact. Our project supports the objectives of Häme Circular Economy Roadmap and the Carbon Neutral Hämeenlinna programme.
