Within the EU innovation project HOUSEFUL (Grant Agreement N°776708), innovative systems for recycling household waste or wastewater as resources are developed on site and implemented in demonstration buildings. The aim of the HOUSEFUL project is to develop technical solutions in combination with services in a participatory process with stakeholders at the building level and thus define circular economy models. The EU project focuses on solutions that enable efficient use of water, waste, energy, and material resources. These solutions will be made generally available on an online platform at the end of the project.
In four demonstration buildings (2 in Spain, 2 in Austria), different technical solutions are applied and developed into circular business models together with stakeholders:read more
Project Cambium, Fehring (Styria)
The demonstration building in Fehring, in southern Styria, is the project Cambium – Living in Community in the former Hadik Barracks Fehring. Here, the organic waste from the building is collected and converted into resources that can be used on site. The organic solids, i.e., the kitchen waste, are recycled in an in-house biogas plant, the biogas produced in the process is used directly on site for cooking, and the digestate from the biogas plant is composted for use in the vegetable garden. The liquid organic components of the toilet wastewater are treated by the VertECO vertical constructed wetlands for safe reuse as service water with perfect nutrient content for fertilizing the vegetable garden and flushing the toilets.

Donaufelder Street, Vienna
The demonstration building in Vienna is located in Floridsdorf on Donaufelder Straße. It can be compared with about 70% of all residential buildings in Austria from the point of view of building construction. For this reason, it is an interesting model for possible replication and dissemination activities within the project. HOUSEFUL will improve the closing of loops in this building by proposing solutions for calculations, new methods for stakeholder engagement, and co-design of innovative solutions for materials, waste, and energy resources.
Building Integrated Modeling (BIM) models and "material passports" will be created for all HOUSEFUL demonstration buildings to enable deconstruction capability of the building at the end of its life cycle.
The Vienna-based Institute for Circular Economy and Nature-based Solutions – alchemia-nova – coordinates the demo building Cambium in Fehring and is also responsible for all greening-related cycles of all demonstration buildings, as well as their automation and monitoring. alchemia-nova is a pioneer in applied decentralized circular economy and works in many other national and international projects, conducting research on products and processes for the implementation of circular economy.
Here you can find some of the developed products, which are also applied and further developed in HOUSEFUL:
AeroPlant is a nature-based air filter that uses the power of plants to purify air. A low-energy fan actively draws in air to send it through an absorbent root substrate and plant foliage, releasing fresh and healthy air. AeroPlant also cools and humidifies the air. Not only is AeroPlant much more aesthetically pleasing than comparable conventional filters, it also requires significantly less energy.

vertECO - Vertical ecosystem for gray water purification
The vertECO technology treats wastewater/grey water in the form of a vertical constructed wetland. The underlying principle is the use of specific plant species in a specific order to promote the purification of polluted water through microbiological activities in the root zone. The vertical arrangement optimizes the use of space and relies on gravity to distribute water throughout the system. vertECO can be installed outdoors or indoors. These factors enable the key innovation of integrating ecosystem services and green aesthetics directly into the building, resulting in numerous benefits.

LooPi - Plant Urinal For Ladies And Gents
To mitigate climate change impacts, cities are investing in green infrastructure – horizontal and vertical green spaces. To grow, these green spaces need lots of water and nutrients. alchemia-nova's green walls work with wastewater, using contaminants as plant nutrients, while purifying water for reuse. "LooPi – the plant urinal for men and women" is the latest innovation in the series of functional green walls. LooPi is a combination of wastewater management and green infrastructure: wastewater is purified through the integrated green wall and reused for flushing.

From May 2018 to October 2022
This project was funded under Grant Agreement No. 776708 from the European Union Research and Innovation Program (Horizon 2020).
HOUSEFUL Project presentation video
Yes, we all can feel it, summers in cities, like Vienna get sometimes unbearably hot. But let’s not complain like typical Viennese. Let’s focus on the solutions. How to counter “urban heat islands”? Professional inputs and a discussion with the audience will address the question how to oppose urban heat islands.
In 2020, the summer school will have a themativ focus on climate adaptation and mitigation in social housing. Global warming and climate change bring about dramatic challenges for social housing.
