IEA Bioenergy Task 40: Deployment of Biobased Value-Chains (Working Period 2019 - 2021)

IEA Bioenergy Task 40 traditionally focused on international trade and supply chains of biomass for bioenergy. Starting in 2018, the systems view was broadened, also to better meet Austrian requirements. The supply chain focus was maintained, but with a broader premise: The establishment of bio-based value chains for a sustainable and fair bioeconomy.

Virtual Biogas - Biogas-Upgrading and Grid-Injection

Production of natural gas substitute from biogas and grid-injection to the public natural gas grid on an industrial scale using the two-staged membrane separation process gaspermeation. Design and erection of the upgrading plant at the biogas plant Bruck/Leitha as well as monitoring and optimisation of the operational characteristics.

Applying passive technologies in social housing, 1140 Vienna; Utendorfgasse 7

Innovative technology for the treatment of municipal and industrial waste water and process waters (INNOWATEC)

Evaluation of a technology as a supporting module for process water and waste water treatment and testing in laboratory and pilot tests for specific fields of application in operational water management.

Optimization of methane production - the Methane Energy Value Model

The biogas production from energy crops will be analyzed and optimized. Energy crops are grown in an environmentally friendly and sustainable crop rotation system. The project provides a secure basis of data for the biogas production and utilisation. Farmers will invest more into the biogas technology.

Indicators of social sustainability for energy regions of the future (SONAH)

Set of social sustainability indicators, oriented at practice needs, and concept for their use in energy strategy processes, regional energy concepts, planning and operation of plants generating renewable energy

3D*3B - 3D-Concret Printing, Reinforcement for low carbon and bending stressed structures.

The project is about 3D printed structural elements and their integration in building structures. The focus is predominantly set on bending stresses structural elements like panels and slabs. Results will point out technical, logistic and climate relevant aspects.

Development of agitation systems in biogas plants in order to optimize mixing-behaviour and to reduce energy demand with the help of Computational Fluid Dynamics (CFD) simulation

The purpose of this project is the investigation of the mixing-behaviour and performance of the agitation systems in biogas plants, and to present them through Computational Fluid Dynamics (CFD) simulation. This EDP-tool can model and predict the actual fluid dynamics in a closed system. Thus it may help to plan optimal reactor geometries, position and combination of agitation systems as well as to minimize the energy requirements.

Sprayed-on and Plaster-covered Cellulose-insulation without vapour barrier

Investigations on the fundamental suitability of sprayed-on and plaster-covered cellulose insulation for thermal insulation of buildings.

Establishment of a "Sustainability Label for repair-friendly constructed electr(on)ic household appliances (brown and white goods) as a shopping guideline for consumers"

The scope of the project comprises the development of criteria for a Sustainability Label for repair-friendly constructed appliances, marketing and PR activities with a focus on producers and consumers, training of auditors and labelling of at least one product.

EASEY Online Rating Preparation Transfer

Transfer of conceptual knowledge about rating of sustainability performance of SMEs to three different groups of consultants dealing with financial data. Sustainability in business, that is the thesis, contributes significantly to an increasing repay capability.

FT-Biofuels in Austria

Development of a realistic concept for the production of Fischer-Tropsch-fuels from biomass in a size of about 200.000 to/a in Austria. Comprehensive evaluation of this concept with respect to available biomass resources, and economical and ecological benefits.

IEA Bioenergy Task "Biogas"

Evolution and circulation of the biogas extraction of organic materials through Austrian attendance and collaboration in an international net as well as management of task-emphases

Timber construction for high-density housing

Development of technical and economical solutions for high-density housing in timber construction under consideration of future regulatory developments (case study of a 5-story housing complex in Vienna).

Flucco+ - Flexible user comfort in quarter-hourly CO2-neutral Positive Energy Districts (PED)

The aim of the project is to improve the planning basis for the construction and operation of energy flexible buildings in three specific areas. First the further development of existing models of thermal comfort for dynamic situations, second the quantification of future energy grid usefulness and third the holistic testing of the developed comfort and CO2 model at three potential positive energy districts (PED), taking into account the ecological assessment as well as the life cycle costs.

Organisation and initiation of a multfunctional energy - centre in the community Deutschlandberg

Conception and implementation of a multfunctional energy - centre considering as exemple "Model Güssing", where different possibilities concerning the production- and consumerside are optimised together in order to achieve the aim of an energy - self-sustaining community Deutschlandsberg.

Integrated Service Models for increased resource-efficiency in the business-to-business sector (INERIWI)

For the major resource intensive commercial sectors the real function of products will be ana-lysed and elaborated how to provide the function of the product without selling it. Based on the present material intensity of the branches the potential reduction of environmental burden by applying such models as well as economic and social implications will be deduced.
