Austrian BioCycles

In the project “Austrian BioCycles” the topic of “secondary biomass and potential exploitation in Austria” was examined in a cooperation between alchemia-nova (ALCN), scenario editor (SCED), Austrian Society for Environment and Technology (ÖGUT) and the Institute for Production and Logistics of the University of Natural Resources and Life Sciences Vienna (BOKU).

We assessed the streams of secondary biomass qualitatively and quantitatively and examined the theoretical substitution potential. We can base this study to a large extent on work that the consortium had already done within other studies. We evaluated processing methodologies against the various conversion technologies of specific conversion rates and drew a comparison between secondary biogenic raw materials generated in Austria and the EU. Following a survey of existing infrastructure for potential biorefineries, we developed a logistics concept for an integrated biorefinery network in Austria and present it as a digital map.

The biorefinery concepts envisage the production of bio-based products for a variety of uses, together with profitability assessments and economic and ecological impacts determined under varying framework conditions. We also compared conventional production methods of bio-based materials and integrated biorefinery cascades.

HOUSEFUL

Innovative circular solutions and services for new business opportunities in the EU housing sector

HOUSEFUL is an EU Innovation project submitted and approved under call topic CIRC-1-2017 (Systemic, eco-innovative approaches to the circular economy: large scale demonstration projects) (Grant Agreement No. 776708).

The project’s aim is to develop technical solutions in combination with building-level services to be offered within the framework of closed loop management models. The focus is on solutions that enable the efficient use of water, waste, energy and material resources. These solutions will be sought and developed in co-creation workshops with stakeholders and will be available to the public in an on-line software.

A wide spectrum of technical solutions will be developed and demonstrated at four demonstration buildings (two in Spain, near Barcelona, one in Vienna and one in Fehring, Austria), and then translated into circular business models developed with expert stakeholders. One of the frontrunner buildings is the Cambium Community Project in the former military barrack in Fehring, Austria. It is planned to collect the organic waste from the building and transform it into usable resources. Organic solid waste will be converted into biogas, used directly within the building and the digestate will be composted on site. The liquid organic-waste components will be processed by a vertical plant-treatment unit, producing valuable fertilizer for on-site agricultural use.

BIM (Building Integrated Modeling) surveys of all 4 demonstration buildings, and the creation of “Material Passports” to enhance recovery are foreseen within the project, as well as the development of a method to evaluate the circularity of buildings.

alchemia-nova will apart from coordinating the demonstration building Cambium, work intensively with stakeholders from all areas, and is also responsible for all greening cycles and their automation processes, as well as for a series of other tasks as a circular economy pioneer.

COST Circular Cities

Implementing nature based solutions for creating a resourceful circular city

Resource depletion, climate change and degradation of ecosystems are challenges faced by cities worldwide and will increase if cities do not adapt. In order to tackle those challenges, it is necessary to transform our cities into sustainable systems using a holistic approach. One element in achieving this transition is the implementation of nature-based solutions (NBS). They can provide a range of ecosystem services beneficial for the urban biosphere such as regulation of micro-climates, flood prevention, water treatment, food provision and more. However, most NBS are implemented serving only one single purpose. Adopting the concept of circular economy by combining different types of services and returning resources to the city, would increase the benefits gained for urban areas. This COST Action aims to establish a network testing the hypothesis that: A circular flow system that implements NBS for managing nutrients and resources within the urban biosphere will lead to a resilient, sustainable and healthy urban environment . To tackle this challenge five working groups (WGs) give their contribution on closing the resource cycle within the urban biosphere. The five WGs will deal with the built environment, urban water, resource recovery, urban farming and transformation tools connecting the WGs and the socio-economic impact.

The project was initiated by alchemia-nova. The main aim and objective of the Action is to build an interdisciplinary platform for connecting city planners, architects, system designers, economists, engineers and researchers from social and natural sciences that develop nature based solutions in the urban landscape that are facilitate circular economies based on the 3Rs (Reduce, Reuse and Recover) and allow cities to cope with future challenges.

ReCO2ST overview

RECO2ST Results

As specialists in the nature-based solutions, alchemia-nova has developed two automatable bio-technical indoor air-treatment systems for inclusion in the Retrofit-Kit. The systems are based on the air purification, cooling and humidification properties of specially selected plants. They improve indoor air quality and thermal comfort by filtering out harmful Volatile Organic Compounds (VOCs) and Particulate Matter (PM), and by regulating relative humidity levels, enhancing also significantly the aesthetics of the indoor environment. The first comprises of a decentralised pot-plant-based system (AeroPlant) easily installed into buildings as part of a retrofit-kit, or as stand-alone solutions. The second system (Casetta) is a semi-centralised unit that can be installed in a window, in which ambient-air is treated by directing ventilation through a “winter garden”-like plant chamber.

pop-up environments

Urban pop-up housing environments (PUEs) and their potential as local innovation systems
The aim of the project

The project aim is to contribute to the transition of the construction sector from linear to circular models, by using temporary PUEs, so as to make urban reuse strategies more sustainable in social, economic and environmental terms, in an attempt to find adaptable and flexible paradigms for different urban contexts.

Background

The need for temporary housing particularly in urban environments is expected to increase dramatically. To address these urgent demands, it is important to find affordable and flexible but sustainable and reusable concepts that are easy to construct and rapid to implement. However, to go one step further, temporary housing will be conceptualized as local innovation systems. In this respect, this proposal focuses on an inter- and trans-disciplinary approach to systematically investigate and evaluate existing temporary housing options, and to create holistic, innovative and sustainable models for pop-up living systems in urban environments.

Methods from urban and landscape planning, architecture and building systems technologies are interlinked to resource related disciplines such as energy optimization, green technologies, sustainable waste management, water supply and wastewater treatment as well as social and political sciences. Diverse modelling approaches are integrated into a cross-disciplinary model and subsequent scenarios of pop-up housing environments are developed for different target groups and types of urban spaces. Risk assessment approaches as well as energy and life-cycle-assessments are applied to evaluate the housing models. This research clearly goes beyond state-of-the-art, since for the first time a systemic modelling approach is applied to develop high-quality and sustainable temporary housing environments as innovation niches within urban systems.

Temporary housing scenarios

Within the project, six possible temporary housing scenarios were defined for the context of Vienna. The scenarios were developed with the aid of stakeholders and six suitable areas for temporary housing in the city were identified.

Six suitable areas for temporary housing in the Viennese context
  1. vacant lots, understood as urban gaps due to the lack of buildings in densely constructed lots;
  2. empty buildings, like factories and industries that have fallen into disuse and are now abandoned;
  3. large green open spaces (whereby these spaces provide important functions which must be taken into consideration);
  4. rail traffic areas which are no longer in use and the reuse of train wagons for residential purposes;
  5. vacant ground floor retail spaces, before a new destination is found;
  6. bodies of water, like rivers, and the reuse of old cargo ships.
Developed scenarios

The scenarios were developed by alchemia-nova and the consortium in a step-by-step process:

  1. definition of the scenario (during workshops with interested stakeholders);
  2. concept design (in collaboration with the students of the “POPUP SHELTER – Design Studio” course at the Technical University of Vienna);
  3. architecture modelling for the definition of the physical 3D models (lead by alchemia-nova);
  4. model assessment for the definition of energy, materials and waste flows.
Project Progress

As part of the ongoing project, the six scenarios were at different levels of development while the questionnaire sessions were being conducted: scenarios #1, #2 and #3 were completely defined regarding concept and architecture and almost completed regarding the model assessment. For scenarios #4, #5 and #6, concepts and architectures were defined, but the model assessment was still ongoing. Among the various benefits considered for the selection of scenarios, the reuse of building gaps (scenario #1), empty buildings (scenario #2) and vacant ground floor retail spaces (scenario #5) have the objective to give back to the community spaces which are otherwise cut off from the urban context. There are also positive impacts regarding transport, energy conservation and raw materials, since the structures are already there, and large quantities of new building materials are not necessary. The realization of PUEs in green and shaded spaces has the objective of finding new and cooler areas of the city to escape heat islands (scenario #3), while the reuse of trains (scenario #4) and ships (scenario #6) allows a second life for the vehicles, the use of otherwise unused spaces and efficient transportation of the housing units to European destinations along the railway or river networks.

Drivers and barriers for international transferability

In order to explore drivers and barriers of the scenarios regarding the international transferability of the concepts, online questionnaire sessions were conducted with an international audience. The feedback obtained by the participants allowed an analysis of the applicability of the concepts to other urban environments under comparable conditions at the international level. The results obtained from the questionnaire sessions allowed insight on the international perception of temporary pop-up environments and, specifically, strengths and weaknesses of the scenarios, as well as their possible applicability in the local contexts of the respondents. It was observed that while the perceptions of what requirements temporary housing must fulfill in order to be sustainable are quite uniform among the experts, the identified barriers for implementation within the different international contexts differed greatly. The designs of these temporary housing scenarios, which rely heavily on local resources and systems, are strongly interwoven with the fabric and conditions of the city they were conceptualized for. While this serves to promote the sustainability of these solutions, it poses a particular challenge for the international transferability, requiring heavy adaptation for other contexts.

GRecoMet

Green Recovery of Metals

Tapping the results from Bio-Ore and PhytoMine, GRecoMet  is set up as a pioneering project exploring new pathways of non-ferrous metal recovery. Metals, diffusely dispersed in waste incineration ash, are brought in solution through microbial leaching in an environmentally friendly and cost-effective way. Depending on the characteristics of the different metals and the specific method, up to 100% mobilization is expected. The obtained bioleachate is used for rhizofiltration and biosorption experiments. (1) alchemia-nova GmbH has developed and patented a horizontal constructed wetland (in the course of the EU project demEAUmed), which will be adapted to enrich metals hydroponically in the plant tissue of selected metal accumulators (a process called rhizofiltration). (2) Additionally, different natural materials will be tested for biosorption properties. In a series of experiments residues from agro-forestry and food industry (egg shells, potato peels, residues from sugar beet and cereal processing,… ) and dried plant and algae biomass will be used for adsorption of metals from bioleachate. (3) Further trials deal with accumulation of metals in living microalgae and cyanobacteria. (4) In addition, adsorption of metals from bioleachate to oligopeptids and other polymers will be tested. Innovative gentle chemical processes for the recovery of metals from the obtained biomass will then be optimised based on findings of the project Bergwerk Pflanze (e.g. using ultrasonication to aid the remobilisation of metals from biomass) to develop efficient and cost-effective ways to gain high-quality bio-ores, salts or pure metals.
