HYDROUSA, an EU Horizon 2020 flagship (2016-2021, €8M budget), pioneers circular water management in the Mediterranean\’s arid zones, blending biomimicry, low-tech nature-based solutions (NBS), and IoT sensors. Led by Greece\’s National Technical University of Athens with 28 partners across Croatia, Italy, Lebanon, and Palestine, it processes sewage, rainwater, groundwater, and seawater into hygienic freshwater for agriculture, industry, and recharge—closing loops to combat scarcity affecting 180M people.

Demonstration sites in Attica (Greece), Sicily (Italy), and beyond employ modular \”HydroModules\”: vertical flow wetlands mimicking root zones, anaerobic baffled reactors emulating gut digestion, and floating treatment islands inspired by beaver dams. Sensors track TSS, BOD, pathogens (e.g., E.coli <10 CFU/100mL output), and nutrients, with AI optimizing flows via apps. Outputs exceed WHO standards, yielding 1,000 m³/day per site while generating biogas for energy (up to 20% recovery).

Biomimicry shines in low-energy designs: subsurface infiltration beds copy aquifers, boosting recharge by 30%; vertical gardens emulate terraced rice paddies for evapotranspiration. Socially, it trains 500+ locals, fostering jobs in \”Water As a Service\” models. Economic viability: €0.5-1/m³ treatment costs versus €2+ for desalination.

Impacts include 90% water reuse in pilots, slashing imports, and biodiversity gains (e.g., pollinator habitats). Scalable for urban Romania—think Bucharest retrofits amid Danube stresses—HYDROUSA\’s open-source blueprints support PUZ integrations.

Legacy endures via HYDROUSA 2.0, influencing UN SDGs and Blue Economy. It proves architecture\’s role in resilience: buildings as water factories.

BryoSoil is an innovative biomimetic stormwater management system developed by a student team from Pontificia Universidad Javeriana in Bogotá, Colombia. Inspired by bryophytes (mosses and similar plants) from the Andean páramo ecosystems, it won first place in the student category of the 2019 Biomimicry Global Design Challenge.greentalents+2

Biomimetic Inspiration

BryoSoil draws from bryophyte geometries observed in Colombia\’s Sumapaz páramo, analyzed via scanning electron microscopy at the university.

It replaces traditional pipe-based drainage with permeable pavements that infiltrate water into natural soil or harvest it for reuse. Configurations adapt to flood risk, combating urban heat islands while enhancing sustainability as cities grow amid climate change.asknature+1

Key Functions

• Flow Management: Geometric patterns reduce velocity and prevent erosion.
• Water Retention: Captures and stores runoff for infiltration or evaporation.
• Multi-Layer Efficiency: Underground modules separate clean water from pollutants.[asknature]​

The Bioluminescent Pavilion Lighting (bacteria-based) refers to an experimental design concept and ongoing research project aimed at creating self-sufficient, passive urban lighting using living organisms.

Project: BioLumCity

This initiative is a collaboration between the Centre for Research in Agricultural Genomics (CRAG) and the International University of Catalonia (UIC), co-led by Jae-Seong Yang and Alberto T. Estévez.

• Core Concept: The project aims to replace electric urban lighting with \”living light\” (bioluminescence) to reduce energy consumption and light pollution. It involves designing architectural elements—such as pavilions, urban screens, and streetlamps—that host bioluminescent microorganisms.
• Biological Agent: The research focuses on Aliivibrio fischeri, a naturally bioluminescent marine bacterium.
  • Mechanism: These bacteria emit blue-green light (~490 nm) through a chemical reaction involving the enzyme luciferase. This is a form of chemiluminescence that does not require light absorption to emit light (unlike fluorescence).
  • Application: The bacteria are cultured in a \”bioink\” and seeded onto customized 3D-printed scaffolds (tiles). The design of these tiles features a specific \”field-diffusion pattern\” with peaks and wells to optimize bacterial attachment, oxygen access, and light visibility.
• Pavilion Integration: The sources mention the development of 3D-printed urban tiles that function as \”bioreceptive\” screens. These tiles can be assembled into larger structures, such as pavilions or facades.
  • Performance: In experiments, the bacterial bioink on the 3D-printed scaffolds emitted visible light for up to 10 days without needing a nutrient recharge.
  • Enclosure: To be viable in an urban environment, these bacterial cultures would be enclosed within architectural elements (e.g., using ion-exchange membranes or dense polycarbonate) to protect the colony while allowing light to escape.

Other Bacterial Bioluminescence Concepts

The sources also briefly mention a project by Panasonic called \”BioLight\”, which similarly investigates the use of luminescent bacteria to create \”bioreceptive\” pavilions and furniture, though fewer details are provided compared to the BioLumCity project.

Future Goals

While the current focus is on bacteria for their natural light-emitting properties, the BioLumCity project is also researching the genetic modification of microalgae (Chlamydomonas reinhardtii) to create organisms that are both bioluminescent and photosynthetic. This would create a system that illuminates cities at night while actively capturing CO2 during the day.
