The most significant thermal water resource in the Carpathian Basin can be found under the territory of the Hungarian-Serbian border, in the Szeged-Morahalom-Subotica triangle. The abstraction for extensive and complex utilization is currently being started on both sides of the border. For the safe and sustainable abstraction, and its international monitoring, it is necessary to determine the hydrogeological-hydrodynamic features of the common thermal water base, and to elaborate a two-phase 4D model of the water base for the mapping of the water resource and its gas content.

The EU has set clear targets regarding energy conservation of buildings and heavily supports activities towards achieving these targets on a European scale. The Green Deal, renovation wave, Energy Performance of Buildings Directive (EPBD) and Energy Efficiency Directive (EED) are some examples of EU's actions. For more than a decade, Energy Performance Certificates provide detailed data about the current energy needs of a building/building unit as well as information about the building construction and systems. A Building Renovation Passport (BRP) has, on a European level lately, been conceived as a tool that can stimulate cost-effective renovation in the form of a long-term basis, step-by-step deep renovation roadmap following defined quality criteria, and outline energy renovation measures that will improve the energy performance of the building. A Digital Building Logbook (DBL) is another tool that can serve as an archive where all building information can be stored and continuously updated. In this way, a full record of the building history will be electronically available with data regarding construction plans and permits, maintenance and system replacement activities, energy and heat consumption and production, etc. Building Renovation Passports and the Digital Building Logbook are tools that can help in achieving energy efficiency in existing buildings and contribute to reaching the EU renovation wave goals. The objective of this report is to investigate how the current EPC schemes best make the link towards the BRP and the DBL to further incentivise and stimulate cost-effective deep energy renovations of buildings across Europe. Three surveys were carried out to collect relevant information about the current status of the EPC data records and to identify stakeholders' potential needs, perceptions, thoughts and expectations, regarding a future connection between the EPC and the BRP or DBL. These surveys were prepared in two forms: using an excel file format circulated via email, and through an online questionnaire. Their completion was carried out by 16 countries. Regarding the EPCs, the state or regional energy agencies are the owner of the EPC data records and make full use of them. Their current main usage is for statistical reasons in the majority of the countries and their access is publicly available in half of the responding countries. Many common data is stored in the EPC database which can be linked with other tools (half of the EPC databases are already linked with another source). Regarding the BRP, a review of existing European schemes showed that successful BRPs have combined the renovation advice with financial support, legal requirements and/or communication campaigns. An important factor of the BRP is that it should be issued by a qualified expert and should provide customised measures for the specific building together with the investment costs per renovation measure(s). The DBL analysis showed that it should provide access to building information and contribute to better decision-making for future interventions as well as operation, use and maintenance records. The building owner/user is proposed to have full access to the logbook and provide/input about energy bills and building plans/construction materials info. An important aspect is that every time the building undergoes intervention works, the DBL should be updated accordingly. The most important barrier is the lack of motivation to update the DBL contents followed by the absence of synergies and consistency with other tools. Another interesting finding is that both BRP and DBL should be fed automatically by EPC data without any user interference. There is a clear possible interconnection between EPC data and BRP and DBL future contents. In addition, BRP can be an instrument to increase the renovation rates and DBLs are necessary for the management of buildings' information. The linkage of EPC data and BRP and DBL can be strengthened by introducing BRP and DBL as voluntary schemes under national incentives and should be fully implemented once they have demonstrated acceptance by the stakeholders.

Bio-based and biodegradable plastics (BBPs) are innovative materials, wholly or partially produced from biomass, with the potential to enhance the circulation of resources in the biological cycle of the Ellen MacArthur Foundation’s butterfly diagram. Although BBPs are generally considered more environmental-friendly than conventional plastics, robust scientific evidence is still missing. The lack of tools and metrics to assess the circularity and sustainability of the BBPs industry poses relevant challenges for its upscaling and contribution to climate neutrality goals in Europe. It calls for adopting system and life cycle thinking, guided by multi-level and multi-dimensional examinations, which led researchers to build a comprehensive picture of trends, gaps and future orientations that may boost a sustainable circular bioeconomy in the sector. The value- chain based and multi-faceted SWOT analysis that emerged from the intersection of system and corporate data reveals the need to establish a combined circular bioeconomy strategy where incentives to integrated local supply chain, dedicated EPR scheme, eco-design guidelines, revised EoL standards, new clear labelling schemes and harmonised sustainability criteria should be prioritized and conjointly pursued to accelerate the transition towards a sustainable circular bioeconomy of the BBPs value chain.

Recent extreme weather events have resulted in an ongoing discussion on the issues of land use and compensation payments within Austrian agriculture. Building on a functional evaluation system for agricultural lands as developed within the Interreg IIIB project “ILUP”, the national project “Agriculture and Flooding” has as its goal to classify the flood-protection contribution and flood sensitivity of agricultural lands. This, in turn, enables the recommendation of targeted measures for potentially improving flood situations, as well as an estimate of their implementation costs. In addition to the digital soil map, other fundamental sources used for the project are the digital flood risk map, IACS land-use data and works by the Institute for Land and Water Management Research. Reference values and marginal returns sourced from the Federal Institute of Agricultural Economics also flow into the cost estimates for the recommended combination. The results will contribute to an understanding of the multifunctionality of agricultural lands and to the setting of priorities on a regional scale regarding packaged flood-prevention and damage-minimization. However, the results at hand can only serve as one step toward regional flood protection projects, whose development will require the cooperation of all interest groups.

A reduction in the availability of phosphate rock resources for fertiliser production coincides with an increase in phosphorus-rich dairy wastewater in Europe. This confluence of events has led to the development of technologies for phosphorus recovery from dairy wastewater and the use of the products as fertilisers in agriculture. This thesis aims to contribute both to the technical development of this emerging technical system and methodological development of assessing the sustainability of it with regard to (1) the identification and selection of sustainability indicators, and (2) the assessment of life cycle environmental impacts. The thesis describes an approach developed for identifying and selecting sustainability indicators by reviewing scientific documents and interviews as well as an approach employed for performing a meta-analysis of previously published life cycle assessment results to cope with lack of inventory data. The employed method for indicator selection narrows down an initial set of 382 sustainability indicators identified in the literature to 26, which were considered representative and useful for the assessment of the considered innovative conceptual system. The meta-analysis results suggested that the examined phosphorus recovery technologies exhibited a lower global warming potential and cumulative energy demand than those of dairy wastewater treatment processes and that those technologies recovering phosphorus from the liquid phase had lower impacts than those recovering phosphorus from sludge or ash.

“A PED is a process, not a product” This “How to PED’’ cookbook contains experiences, lessons learned, and recommendations gained throughout the 5 years of the +CityxChan- ge EU Horizon 2020 project, specifically focused on the variety of activities necessary to develop and build Positive Energy Districts (PEDs) in smart sustainable cities and communities. Over the course of the book we will draw on the experiences of our 2 Lighthouse Cities, 5 Follower Cities, and 26 other partners, to demonstrate what it takes to build a PED. We show the importance of collaboration and co-creation, involving the right people, designing effective pathways for change, deploying strong partnerships and financing, adapting to existing processes or adapting the processes themselves, developing impactful strategies, building new systems and services, and creating new infrastructure in PED projects. This cookbook represents the processes and results of +CityxChange, where we all contribute with our own recipes & flavours. Just as in real life, recipes often need adjustment to taste. There is no single way to build a PED, so these recipes from our cities provide guidance through the complexities of the journey and share key information that helps initiate and smoothen the processes.
