Determined efforts result in 37% smaller carbon footprint
Adven has systematically lowered the emissions of its plants since the start of the 2000s. As a result of systematic development work carried out last year, the carbon footprint has decreased by 37% compared to the situation in 2012.
The carbon dioxide emissions of countries in the European Union have grown in recent years, and the pressure to mitigate climate change is growing. Adven has conducted comprehensive development work related to greener energy production and reducing the carbon footprint. This development work has produced good results.
In 2017, carbon dioxide emissions were 37% smaller in relation to energy sold (MWh) compared to the situation in 2012. Significant progress was made again compared to the previous year, as the figure for 2016 was 30%.
The average carbon dioxide emissions of district heating in Finland in relation to energy sold amounted to 149 kgCO2/MWh in 2017 (Finnish Energy 2017). Adven’s corresponding figure for last year was 9% lower.
Emissions volumes are tracked according to energy sold (MWh), since the plant base grows and the volume of energy produced varies annually. The figures are therefore comparable, regardless of annual changes in production.
Focus on environmentally friendly solutions and improving energy efficiency
Emissions cuts were achieved, for instance, by converting plants from fossil fuels to biofuels and by offering geoenergy and hybrid solutions for suitable sites.
All new investments and changes made to plants are always geared towards switching to lower-emission fuels. Adven’s new plants are now designed right from the start to be energy efficient.
“Adven’s concept designers have a range of means for improving energy efficiency, for example, through closed cycles. New geoenergy solutions for large properties, as well as more traditional flue gas heat recovery, are also actively used to reduce the carbon footprint,” says Adven’s Environmental Manager, Katja Baumgartner.
Concerns about climate change are also affecting political decisions.The law is the same for everyone, but competitiveness arises from doing things in a new and innovative way. Industrial processes, for example, produce a lot of usable raw material that can be harnessed and re-used.
“Some of our customers’ processes generate plant-based by-products, such as wheat husks. If no other use is found for these, they can be used as fuel in Adven’s plants. One such example is the company Hankkija, where the steam energy required for its plant is generated by combusting ground oat husk, a by-product of production,” explains Baumgartner.
