Low temperature excess heat

Low temperature excess heat
Seedling

Many industrial processes have excess heat. It can be waste heat from paper, steel or chemical industries, but also from electrolysers and data centers. By creating connecting processes that have a heat surplus with processes that need heat, circularity can be created.

Sometimes people talk about the concept of high-value heat, which is usually deposited in, for example, the district heating network, but there is also low-value heat. Usually, this excess heat lacks deposition on a larger scale.

The low-grade heat is usually not pressurized and  consists of hot air or hot water between 30-65 degrees. RISE has expertise in the recycling of low-temperature excess heat. At the RISE test and demo facility ICE Datacenter, several different attempts to recover excess heat has been carried out, including heating greenhouses, drying biomass and growing mealworms for egg-producing hens.

AI for climate change

AI for climate change
AI for climate change

We are facing the greatest challenge in modern time. Climate change is already giving rise to extreme weather events around the world. Artificial intelligence can be used both to mitigate and help us adapt to the disasters we face in the future.

Life on Earth is about to change. Climate change is real and we are already seeing more extreme weather events and related crises. Human-caused climate change is one of the major reasons why we are currently seeing the sixth mass extinction of species. In order for humanity to cope with these changes, adaptations must be made on a broad front. Some of these may come from advanced modeling using AI and machine learning.

At RISE, we work with a number of different projects that can help mitigating climate change, as well as improving resilience against its effects. These projects include modeling flows in the Krycklan catchment area outside Umeå using deep learning, modeling risks in circular business models, and AI for efficiency and stability in agriculture.

We run projects to map and analyze biological diversity, to act as decision support for the planning of forests and green areas in urban environments. Sound recordings and camera traps are used today to gather information about how animals move in the wild. We develop advanced AI-driven soundscape analysis to help track important marker species, to build knowledge about how they are being affected by humanity and changes in their habitat. Thus, the current workflow with passive acoustic monitoring devices and camera traps which today require manual analysis become partly automated.

We are a leader in Climate AI Nordics (climateainordics.com), a Nordic network that works to develop and promote collaboration on AI solutions addressing climate change. We are also one of three leading organizations in climes - The Swedish center for impacts of climate extremes(climes.se), working interdisciplinary with research on extreme events resulting from climate change.

We have only seen the beginning of what climate change has in store for us. We have also only seen the beginning of the efforts we are making to meet the challenges ahead. This page will be updated with new information as our work progresses.

New drinking water directive for increased resilience and sustainability

Drinking water

For a resilient water supply, both the supply and quality of the water need to be ensured. It demands materials that last over time and do not cause contamination. The latest update to the EU Drinking Water Directive brings new requirements affecting everyone involved in water supplies, from municipalities and property owners to producers of materials and products. The Materials in contact with drinking water network, operated by RISE, follows how the directive is implemented in Swedish law and provides support and guidance.

The EU Drinking Water Directive has been developed to create a similar management of water in the Member States. The aim is to take care of our water resources so that future generations will have access to a sufficient supply of good quality water. The latest update to the directive came into force in January 2021, with many new items that affect everyone who works with water supply.

“The aim is to better cover the entire chain, from source to tap, and include materials that come into contact with drinking water as well as building aspects that have not been regulated in the Drinking Water Directive before”, says Mylène Trublet, research and business developer at RISE and project manager of the Materials in contact with drinking water network.

Increased requirements for materials in contact with drinking water

The requirements for materials coming into contact with drinking water are governed by Article 11 of the Drinking Water Directive and apply both to new installations and repairs to existing installations for the outlet, preparation, storage and distribution of drinking water.

The changing requirements on materials, type-approval and testing are some of the key issues facing the members of the RISE network Materials in contact with drinking water. Members include the water suppliers as well as manufacturers of materials and products. This network gives access to the latest research and good examples in the field; members meet at seminars and can exchange experiences with each others. How the new directive is implemented in Swedish law is a very current issue.

“The network follows the work on the Drinking Water Directive, at EU and national level. At our next seminar, Boverket, the National Board of Building, Housing and Planning, will provide information about the process for the implementation of the directive into Swedish law, RISE and KIWA will talk about the approval process”, says Mylène Trublet.

The seminar "Materials and products in contact with drinking water" is being held 27 September 2022, and is open to all interested parties.

Tougher requirements could drive the development of unleaded brass

An example of a branch being affected by the tougher requirements is brass industry who have lead in their raw materials. In the new directive, the limit value for lead in drinking water has been halved. In addition, there is an ongoing discussion about the inclusion of lead on the authorisation list in Reach.

“In the long term, there may be a total ban of lead in materials coming into contact with drinking water. If the brass industry wants to live in the future, it will have to reposition, even if it is a challenge, says Mylène Trublet.

Lead makes brass easier to process and is used in valves, water meters and other components. RISE has participated in several research projects looking at both the possibility of manufacturing brass with a lower lead content and to making completely lead-free brass.

Studying how materials, such as lead-free brass, behave in contact with different types of water, can be done in new RISE test environment in Kista called the Water Rig.

“Here, we can compare different materials and products in different types of water and see how they behave, how they degrade and whether substances leach from the material. In the Water Rig, we can also study biofilms and we can test new sensors,” explains Mylène Trublet.

Products with longer lifespan

There are not only increased requirements in the new Drinking Water Directive, it also includes an easing that will be appreciated by many manufacturers.

“The type-approval process for materials and products in contact with drinking water will be harmonised at a certain level for all countries in the EU, with the Directive setting minimum requirements. I see that as positive, although some countries may have additional requirements”, says Mylène Trublet.
In addition to the requirements of the Directive, Sweden aims to develop materials and products for drinking water and wastewater that have a lifespan of 100-150 years.

“The goal is ambitious but it will also contribute to resilience and preparedness. If we can rely on our management system being robust and sustainable, we will have less unplanned maintenance and better readiness in the renovation and renewal of management systems. It is a good idea and also essential that in Sweden, we work towards sustainability and product durability – that is also what we at RISE are working on”, concludes Mylène Trublet.

Materials in contact with drinking water network

This network has 30 members and brings together principals, trade associations, manufacturers of materials and products and relevant authorities.

Members gain access to up-to-date information on legislation, regulatory framework, research, and materials and product development. The network meets regularly to discuss common issues and needs in the field.

Ensure a Resilient and Sustainable Water Supply – for daily operations and in crises

Hand holding glass of water

Municipalities are responsible for the daily water supply. Municipalities are also responsible for water supply during a crisis. Examples of crises include water shortages due to drought, contamination due to hazardous accidental spills, and sabotage in the course of warfare. Ensure that your municipality has a resilient and sustainable water supply for both daily operations and during crises with RISE as a partner.  

Having a resilient and sustainable water supply means that local residents have access to clean water of a good quality every day, all year round. No matter what happens. A resilient and sustainable water supply also means that agriculture and industry get the water they need and do not have to reduce their operations or, in the worst case, shut down due to a lack of quality water.

Based on the Drinking Water Directive, RISE can help your municipality to safeguard a resilient and sustainable water supply. RISE can carry out demand forecasting and scenario analyses for your municipality based on your current water supply objectives and prerequisites relating to water demand and access to water, as well as for the future based on different scenarios concerning societal development and climate change, which covers diverse perspectives from households to agriculture and companies.

Demand forecasting and scenario analyses form the basis for an updated water supply plan, which will ensure a resilient and sustainable water supply for the municipality.

If a municipality does not have an updated and comprehensive water supply plan, it may become difficult to rationally and efficiently meet increased water needs and potential crises. It also result in increased costs for the municipality and the community.

Tailored, expert team for your municipality’s challenges

RISE is a governmental, independent research institute with both broad and deep expertise in water supply, sewage and urban runoff management, crisis preparedness, AI, digitalisation and cybersecurity, community development, jurisprudence, and many other fields. By partnering with RISE, you get access to a tailored, expert team based on your challenges. Since RISE is a government-owned research institute, we also provide you with wholly unbiased expert advice based on the unique situation in your municipality.

RISE collaborates with many municipalities, county administrative boards, authorities, and other operators, providing a broad system perspective as well as enabling further exchange of experience between municipalities along with opportunities for cross-border collaboration.  

What RISE can offer your municipality

Based on the conditions and objectives of your municipality, RISE will carry out demand forecasting and scenario analyses. In consultation with you, we will create a robust, updated water supply plan that will ensure a resilient and sustainable water supply for both daily operations and during a crisis. The new water supply plan provides assurance for municipal authorities and the municipality’s residents, as well as for agriculture and industries. The updated water supply plan comprises an overview of the municipality’s current and future needs, along with scenario descriptions of potential crises. The updated water supply plan also provides a strategy for how the municipality safeguards water supply and addresses risks by charting and prioritising measures to be taken.

Through continued collaboration, RISE can assist in implementing measures and any other necessary implementation to ensure that the updated water supply plan is fulfilled.

Division: Do not use - Division Built Environment

When the standard and test bed are in place, comparison of facilities are possible and requirements can be placed on the facilities' performance. This will contribute to a more sustainable society and reduced emissions of pollutions. The test bed will also help suppliers evaluate, test and optimize their products.

This project is a continuation of the projects " Classification of manufactured treatment devices for stormwater management" and " Pre-study of test bed for stormwater facilities", for more information see link to project pages below.

Specific goals of this project are:

  1. Answer the remaining questions of both practical and theoretical nature to enable the construction of the test bed.
  2. Investigate and develop proposals for a business model for the test bed.
  3. Examine the use of sensors in the test bed.
  4. Carry out design of the test bed.
  5. Have a continued dialogue with companies and experts so that the project is anchored in a good way and experience is gained internationally.

The goal is that this project will create sufficient clarity and knowledge to take the test bed in the next step, evaluate it and evaluate the standard and classification with the help of the test bed. Furthermore, the ambition is to work with SIS to develop a proposal for a new national standard (SNS) or work for an international standard.

Samverkan för hållbar dagvatten- och skyfallshantering på kvartersmark

SODA - dagvatten och skyfall

Projektet SODA har lett till ökad motståndskraft mot klimatförändringarna på befintlig och nyexploaterad kvartersmark genom att förbättra förutsättningarna för en hållbar dagvatten- och skyfallshantering.

Division: Använd ej - Division Samhällsbyggnad

Klimatförändringarna väntas leda till förändrade nederbördsmönster, såväl längre torrperioder som skyfall väntas bli vanligare och urbana områden med hög andel hårdgjorda ytor är särskilt sårbara. En hållbar dagvattenhantering kan bidra till att öka våra städers motståndskraft mot skyfall och torka genom att fördröja vatten på platser där det kan nyttjas som en resurs och inte riskerar att orsaka skada. Rätt utformat kan hållbara dagvattenåtgärder även öka trivsel och bidra till biologisk mångfald. Kvartersmarken utgör cirka 70 % av våra städer, och har därmed en enorm potential att bidra med ytor för åtgärder. 

Dagvatten- och skyfallshantering på kvartersmark är dock särskilt utmanande på grund av det stora antalet inblandade aktörer, lagstiftningen som i dagsläget inte möjliggör en tydlig kravställning, och bristande kunskap om tekniker för hållbar vattenhantering. Detta gäller vid nybyggnation och i synnerhet när åtgärder ska till i den befintliga byggda miljön. SODA projektet har involverat aktörer från alla delar av samhällsbyggnadsprocessen och har fokuserat på de nyckelfrågor som behöver lösas för att uppnå en hållbar dagvatten- och skyfallshantering på kvartersmark.

Projektet har arbetat med att bryta låsningar och underlätta
samverkan, genom (1) Process- och organisationsutveckling (2) modeller för samverkan och samfinansiering (3) utveckling av en samordningsroll för dagvatten (4) upphandlingsstöd och teknikutveckling (5) Utbildningsinsatser mot en bredd av aktörer, och (6) intern och extern kommunikation. Det långsiktiga målet är fler dagvatten- och skyfallslösningar på kvartersmark som ger en ökad robusthet mot klimatförändringarna, i den befintliga miljön såväl som vid nybyggnation.

The roles and opportunities for businesses to prevent water shortages

Companies role to prevent water shortage
Work water lab

The project addresses the challenge of reducing water consumption in Swedish companies. The goal is to create incentives for companies to save water and develop support for them to implement water-saving measures. Central in the project are interviews to map the companies' conditions and obstacles to water saving and to identify important actors.

Division: Do not use - Division Built Environment

The companies account for about two thirds of the water consumption in Sweden and consume more water than the corresponding companies in southern Europe. This waste of resources needs to end, both because water supply is starting to become limited in many places in the Sweden and since unnecessary water consumption also leads to a the use of extra resources to pump and purify these diluted water streams, which loads both water sources and recipients.

The project is carried out together with Region Kalmar Län. Central to the project are interviews with companies and other actors in the Kalmar County to map the companies' conditions and obstacles to carry out water saving. Actors important to involve to create long-term synergy effects and maximize dissemination are integrated into the work.

This is a preparatory project that will build, evaluate and anchor the following initiatives which are then demonstrated in implementation projects, if granted:

  • Demonstration of water saving at selected companies to verify systematic method for water mapping and to develop a calculation model that also shows indirect savings and added value with water savings.
  • Build local collaboration and system solutions for water saving.
  • Advisory services to companies within water saving.
  • Regional/national business network to educate and exchange experiences in water saving.

All the methods and initiatives that will be developed will be directly scalable from regional to national level, to promote the effective dissemination of the project's results.

Product-Services for Promoting Resource Efficiency and Sustainability

PROSPERITY

PROSPERITY generates knowledge on the interaction between business models patterns and user practices, and sustainability impacts. The project aims to benefit manufacturers from industries in the consumer sectors with high environmental impacts, and produce academic results at the cutting edge in the field of business models for sustainability.

Division: Do not use - Division Built Environment

PROSPERITY is a three-year project that examines how product-service business models can promote resource- efficiency and reduced climatic impacts via novel modes of production, consumption and use. Product-services are seen as a means to revolutionise the way in which consumers satisfy their needs and wants whilst making significant resource efficiency gains across the value chain. Yet there is a lack of knowledge on the ways in which existing and potential users of product-services contribute to business model development, and on how consumer behaviour can support or hinder resource-efficiency gains. Further, whilst recent studies have hypothesised the potential roles business models can play in the transition to a more sustainable society, there is a lack of empirical evidence to show that such developments can reorient sociotechnical systems and transform practices related to the consumption and use of manufactured products. PROSPERITY adopts a multidisciplinary approach that merges perspectives on business models, social practice theory and transition theory to study the development of new business models in in highly polluting manufacturing industries within Sweden and the Netherlands. The project aims to generate knowledge that will push boundaries within the academic community and benefit societal practitioners that seek to bring about enduring change towards a more climate-friendly and efficient use of natural resources.

This is a preparatory project that focuses on identifying measures with great potential for water saving and creating conditions for implementing and evaluating the methods in an implementation project.

The purpose of the project is to gather the most important actors and create conditions for reducing water consumption in households in Sweden by identifying and characterizing methods that can be used for this purpose so that informative decisions can be made and the methods that give the greatest effect can be implemented.

Within the project, good examples of solutions that have been used nationally and internationally have been collected. Solutions in the following areas are identified:

  • Policy and legislation
  • Restrictions
  • Financial incentives
  • Information
  • Nudging
  • Technical solutions
  • Alternative water quality
  • Shared water use
  • Combinations of methods above
