HELEN: Perspectives into sustainable and just energy transition

The energy network of the future will be composed of energy networks, in which stakeholders are not only different energy communities (citizens, corporations), but also different species and organisms, that energy production impacts. The goal of the challenge is to help HELEN understand how future’s energy networks are constructed ja and how an energy company can act as an enabler of sustainable transformation/transition. The wish is to get research topics from transdisciplinary points of views and themes, which are thought to have the most impact. Come join us in making a more sustainabile energy transition!

VALMET: What kinds of machines are needed in a sustainable future? The significance of the transition to sustainability for the paper, cardboard and pulp machinery industry.

The significance of the paper, cardboard and pulp machinery industry as enablers of current global forestry practices is generally recognized. Yet this industry is seldom explicitly thematized as an object for sustainability research. Major changes in these practices as a result of, for instance, implementing new global forestry regulations in the face of the climate crisis would inevitably also imply changes for this part of global industrial infrastructure. This challenge encourages students to consider what sustainable adaptation could imply for this industrial segment in the light of existing climate scenarios. What could, should and would have to be done in the light of the climate crisis? Where, when, how and by whom?

UH: The higher education sector as part of sustainability transformation- how can higher education organizations anticipate and respond to the interconnectedness and complexity of sustainability issues?

How can the carbon neutrality objectives of higher education institutions be linked with the objective of safeguarding biodiversity? What other key sustainability and responsibility impacts should higher education institutions anticipate? Universities are large organizations at national level. The University of Helsinki alone is a community the size of a Finnish municipality, with around 40 000 people. In addition to its research and teaching activities, the university is a major societal actor, as well as a major property owner, investor and acquirer. The University's influence extends wide in society both at a national and global level. Carbon footprint calculation and reducing the climate impact of their own activities have been a topical challenge for universities in recent years. In addition to climate work, universities are committed to safeguarding biodiversity. It has been argued that, in terms of nature damage, universities should aim for no net loss for their own activities by 2030 - i.e. avoiding and reducing nature damage and compensating for the remaining damage.   How can the goal of zero net loss be measured and considered in the university context, and what does it mean in particular in the context of the carbon neutrality objective? How can the different objectives be achieved simultaneously, taking into account the need for a fair transition, the rights of other species and the safeguarding of ecosystem services?

The University of Helsinki aims to be a pioneer and trendsetter in sustainable development. What does this mean in an ever-changing environment, characterized by uncertain economic conditions and an acute energy crisis? What role will technology and artificial intelligence play in the sustainability transformation of higher education? What other sustainability and responsibility issues should the higher education sector address?

Metsägroup: How to build and communicate acceptable, progressive and impactful sustainability measures for the future forest industry?  

In forestry and forest industry, sustainability measures and indicators are always inseparable from and intertwined with the scenarios through which they get their context, meaning and practical implementation. Recently, scenarios pertaining to sustainability of forestry and forest industry have undergone multiple and rapid changes due to increased significance of climate and biodiversity issues. How can forestry and forest industry take these changes into consideration and include in industrial processes?  What are roles of sustainability indicators given possible rapid shifting of sustainability scenarios? In which ways could sustainability indicators forestry and forest industry be developed to take such shifts into account? 

HSY: Challenge: Nitrogen cycling in sustainable cities – challenges and opportunities for social behaviour, waste water treatment and biowaste nutrient recycling.

Wastewater treatment and biowaste recycling systems are well developed in big cities like the Helsinki Metropolitan Area. Biowaste digestion and the subsequent use of digestate as a fertilizer is an efficient way of recycling nitrogen. Nitrogen in wastewater is cycled and removed using same microbial processes that take place in nature. Nitrous oxide, which is a powerful greenhouse gas that forms the largest part of the carbon footprint of wastewater treatment, is produced in both nature and wastewater treatment plants. We are interested in what valuable can be learned from the nature to improve wastewater treatment and to decrease the carbon footprint of nitrogen removal. Both wastewater treatment and biowaste recycling are also affected by consumer behavior. Most of the municipal biowaste is still unsorted and thus incinerated with mixed waste, leading to a loss of valuable nutrients. On the other hand, the current substantial increase in consumption of protein rich food causes high nitrogen levels in municipal wastewater, which increases the consumption of chemicals and energy. The overarching goal of our challenge is to learn how to enhance nitrogen treatment and cycling in cities. We welcome all students
