Announcing the 2021 Biomimicry Global Design Challenge Finalists
The Biomimicry Institute has selected 12 finalist teams creating solutions to address the Sustainable Development Goals, all inspired by nature.
MISSOULA, MT — September 23, 2021 — The Biomimicry Institute is proud to announce this year’s Biomimicry Global Design Challenge finalists, an international group of 12 teams that have created ideas inspired by nature’s intelligence aligned with the United Nations’ Sustainable Development Goals (SDGs). Global problems need local solutions, and this group of finalists demonstrate the wide-ranging opportunities biomimicry can offer — challenges related to flooding and evacuation from unexpected storms, water filtration efficiency, heavy metal and light pollution, as well as various adaptations to a warming climate.
This year the Challenge garnered submissions from 92 teams across 26 countries. 58% of submissions addressed SDG GOAL 11: Sustainable Cities and Communities, and more than a quarter of submissions addressed the following SDGs: GOAL 3: Good Health and Well-being; GOAL 6: Clean Water & Sanitation; GOAL 13: Climate Action; and GOAL 14: Life Below Water.
“The submissions and selected finalists for this year’s Biomimicry Global Design Challenge show that innovators from around the world are focused on solving local climate problems by learning from the adaptations and resilience of local organisms and ecosystems,” said Jared Yarnall-Schane, Biomimicry Institute’s Entrepreneurship Director. “The finalists were selected based upon their biomimicry designs, and the potential for their solutions to solve real world challenges.”
Without further ado, the Biomimicry Institute is proud to introducing this year’s finalist projects for the Biomimicry Global Design Challenge:
DELight — In addressing the problem of artificial light at night, which disrupts the circadian rhythm and natural functions of organisms and ecosystems, DElight devised a solution to address common design flaws from existing lighting structures. Inspired by the firefly, Saharan silver ant, and lobster, this multifunctional design emulates nanostructures that efficiently transmit light, guides that light where it is useful (thereby diminishing unnecessary pollution), reduces glare, and incorporates cooling mechanisms. The design ensures that no light is emitted above a 63⁰ angle, uses total internal reflection to create an indirect lighting source, and ultimately decreases significant light pollution and health problems created by streetlights. (Utrecht, Netherlands)
“When living in Delft, one of our team-members experienced the immense effects of skyglow from greenhouses. Here, the nights always seemed like dusk or dawn, never night. While working on this design challenge we realized that, sadly, only two group members have ever actually experienced the beauty of the Milky Way. Confronted with the night sky, we create perspective, reflecting on our place in the universe, and therefore in nature. We want to create a world where everyone can once again be inspired by the stars, every night.” — Team DELight
DRYLGAE — This bio-inspired seaweed dryer was inspired by the camel’s nose, which has an amazing dehumidifying system, the Hercules beetle, which has a body composed of a micro-scale 3D chitin network that enables water absorption, and the moth’s eye nanostructure formation that is efficient at collecting light. These combined strategies create a dry and hot air flow that passively reduces seaweed water content, while preserving the active components, such as vitamins, lipids, and other bioactive molecules. The simple, user-friendly solution relies solely on bio-inspired passive mechanisms to warm-up and dehumidify the air intake. Therefore, it drastically reduces the energy consumption in the seaweed drying process, while delivering a high quality product with an extended shelf life. (Switzerland, China)
“One of our biggest findings in the process is that the answers to humidity management and sunlight harvesting are hidden in the species that live in tropical or subtropical arid ecoregions. These humbling lessons have inspired the mechanisms of our design. By participating in the challenge, we became more conscious of how to not only make use of what nature provides us with, but also become participants of the nature around us.” — Team DRYLGAE
E-Colant.Net — Approximately 21 million people worldwide are affected by river floods every year. In order to build an efficient and sustainable river facility, the E-Colant.Net unit balances river erosion and sediment accumulation, improves the adhesion of plants and soil, and increases water permeability. The solution was Inspired by the pattern arrangement of shark fins, plants’ water filtration structures, and the gills of tilapia. The design provides resilience of the river channel when floods hit, increases filterability, provides biological habitat, and increases ecological diversity. The multi-level river terrace public space design also allows residents to reconnect with the river’s natural elements. (Taichung City, Taiwan)
“Our design sustains the surrounding river ecology, such as fish and all water creatures including aquatic plants, with the local residents by improving the ecology of the river. Local residents can have closer contact with the ecology while also learning about the watershed space and improvements in resource efficiency.” — Team E-Colant.Net
ECO-Serve — Access to fresh drinking water is becoming more challenging worldwide. ECO-Serve is a passive filtration process to harvest atmospheric water in both humid and arid climates, inspired by fish gills, leaf cutter ants’ mounds, and a few desert-specialist plants. The design includes water-harvesting pods that are composed of a double-layer insulated dome with conical top vents, atmospheric water-harvesting combs, inner flow channels, and a central cistern. In a dynamic filtration network sequence, the ECO-serve provides water to people and the planet, from drinking, sanitation, and agriculture to restoring the aquifers and replenishing various ecosystems in a regenerative way. (San Francisco, CA, USA)
“Nature only uses the energy it needs, and relies on freely available energy. Following this principle, our design incorporates a passive ventilation system that uses airflow and pressure gradients. Following the principle that nature also tends to optimize rather than maximize, we hope to not only be able to provide water to people, but also to help replenish groundwater.” — Team ECO-Serve
ENTR — ENTR is an online webbing tool designed for innovation hubs involved in the energy transition. Inspired by organisms that create mutualistic relationships and feedback loops, ENTR’s main feature is an interactive map of activities in which all previous actions taken in the energy transition in the Netherlands are documented by hubs themselves. The idea is to visualize the strategies and reflect on the outcomes of each action. By creating this visualization, hubs are able to see what strategies were effective in the past, as well as which strategies should not be repeated — thereby seeking to close the feedback loop on what’s working to improve efficiency and effectiveness when planning their projects in the energy transition. (Den Haag, Netherlands)
“The energy transition worldwide is not advancing at the rate necessary to meet the UN’s 2050 climate agreement. The ENTR webbing system is designed to create a cooperative and regenerative strategy that innovation hubs can implement to create mutualistic relationship networks and learn from each other’s previous pathways. Despite being tested in the Netherlands, ENTR’s strategy could be applied in any scenario and countries seeking to make the energy transition.” — Team ENTR
Hydro-Canopy Facade System — In a warming climate, many areas are offering residents two options to adapt to survive: air conditioning (which can be unaffordable) and migration. The HydroCanopy offers a low-cost, high-efficiency architectural façade system solution that responds to climatic conditions using passive control strategies that regulate solar radiation, ventilation, thermal inertia, and offers an evaporative cooling system. The design was inspired by two shared characteristics of local organisms of the unique tropical dry forest in La Guajira. The mucous glands in the epidermis of some frogs and toads and the dynamic gradient of density and size of leaves in the canopy of trees both have a system of gradient layers used to regulate temperature, capture and store water, take advantage of solar radiation, and protect themselves from the wind. The team sought a positive economic and social solution by creating HydroCanopy to respond to the need for affordability and flexibility for its production and mass replicability, using low-cost, locally available materials designed for easy implementation and local adaptation. (Bogotá, Colombia)
“This biomimicry challenge allowed us as a team to explore the different characteristics inside Colombia’s tropical dry forest, as a unique ecosystem in the world. Nature inspired our architectural projects, leading us to new strategies that are more efficient and friendly to the environment around us.” — Team Hydro-Canopy Facade System
Insu-Ram — The buildings in La Guajira, especially housing, present structural and thermal comfort problems due to the current construction materials and the underutilization of available resources in the area. Insu-ram is a system of assemblable clay blocks inspired by the cells in the elytra, or hardened wing covers, of certain beetles that allow internal air flow to circulate. Insu-ram cools and insulates a space from external heat without the use of machines and incorporates local biodegradable materials, such as rammed earth, clay, and manure to eliminate the concept of waste. The external pattern of the block generates a micro-shading effect and reduces the solar contact surface. It can be produced locally, at a low cost, is easy to replicate, and helps to solve the housing deficit in the area, while offering a way to build thermally comfortable houses in a fast, cheap, and efficient way. (Bogotá, Colombia)
“As architects sometimes we focus on design and traditional construction aspects and tend to forget about nature’s simple solutions. We were touched by the struggle of the communities of rural Colombia, and how sometimes those problems are related to mistreating our ecosystems. All the materials utilized to fabricate our bricks are biodegradable, non toxic, therefore our footprint on the ecosystem is minimal, a relief when it comes to construction which is a very polluting industry.” — Team INSU-RAM
MicroBergy — 24-hour water quality monitoring is key in reducing illegal dumping of toxic heavy metal pollution, and yet it’s expensive and requires significant power supply. MicroBergy is an economical, sustainable, self-powered water quality monitor that generates electrical signals from the pollutants in wastewater. Inspired by the curve of a shark tail fin, the sea snail’s shell spiral, sea anemones’ electrodes, and the barnacle’s shape, the design mimics these forms and then uses bacteria to generate the electrical signals that make this technology self-powered. Without the restrictions of expense and power supply, MicroBergy can be installed in places where existing 24-hour water quality monitors cannot, increasing the capacity for monitoring water quality and illegal dumping of toxic pollutants. (Taipei, Taiwan)
“This challenge provided a great competition platform of… not merely a design concept but also a philosophy of life, an efficient problem-solving methodology and the essential rules of nature. No matter which domains you are in, a biomimetic design mindset can definitely help to boost your career or educational goals… BGDC is truly a life-changing experience for Team MicroBergy!” — Team MicroBergy
MOL — Wax moth caterpillars can eat plastic, leading to interesting sustainability applications. The MOL team is looking to selectively breed wax moth caterpillars to become more efficient plastic decomposers. Additionally, the team of scientists are studying the enzymes that allow the larvae to break down the plastic, and they aim to artificially synthesize the compound for use in chemical recycling. By working with and learning from wax moth caterpillars, MOL has a potential solution to the plastic crisis. (Lviv, Ukraine)
“The Biomimicry challenge made us observe nature and search for patterns more intensively. The challenge also reinforced our belief that relevant innovation with social and environmental impact can be created by learning from nature. We would like to make bio-inspired algorithms an integral part of our daily work. For that, we need to spend much more time in nature.” — Team MOL
PURAERA — The PURAERA design uses a mucus-inspired hydrogel to capture air pollutants from the air in metro transit systems. Within the London Underground, particulate matter (PM2.5) pollution comes from the wear and tear of the rails, which is a result of braking. The biodegradable hydrogel is placed on the walls of train lines inside stations to allow for the best capture of pollutants harming human health. While specifically designed for the conditions of the London Underground, a few small adjustments can recreate the solution in similar situations. (Utrecht, Netherlands)
“Our model captures pollutants at the source, thereby creating better air quality in underground environments. The most important component of our design is circularity. Our hydrogels are made of waste products of another industry and the harmful pollutants can be captured and used as fertilizer or other purposes. By sticking to nature’s way of design, we ensure that our “waste” products will not be dangerous for living organisms, and can even be used by plants.” — Team PURAERA
Re-Leaf: A Modular Emergency Raft — Current flood protocols in the Philippines are mainly preventive rather than reactive. This locally-designed solution focused on the Tumana district serves as a safe and reliable means for citizens to brave the flash floods and unexpected storms that catch many off guard. The Victoria water lily can support weight due to a ribbed structural support at its underside, and this strategy inspired the raft’s design. The double-layered modular platform can be used in a number of ways at times of rest, from a park bench to a roof or even a divider implemented city-wide for ease of access. Once it comes in contact with water, the air pockets would immediately fill and float, supporting the weight of people onboard in the currents of the flood waters. (Manila, Philippines)
“The physical constraints of Tumana’s urban fabric (dense population, narrow vehicular roads, and sidewalks) do not allow for an effective redesign for flood prevention. As such, modular furniture is the most efficient way of helping the residents. It is space-saving and can be utilized all year round. The Re-Leaf considers safety of the residents, particularly flood relief, and also serves them in their day-to-day activities. It’s sustainable in that it is highly reusable and efficient. It serves as protection, as well as a tool for leisure and livelihood.” — Team Re-Leaf
Zooza: Cooler Communities. Brighter Futures — Most often, Urban Heat Islands impact the most vulnerable communities in a city. Zooza is a cooling strategy and community implementation approach inspired by a couple organisms’ abilities to change color in response to UV rays; the microstructure of the white scarab beetle, which scatters light of all wavelengths, creating a brilliant white to keep cool; and the bottlenose dolphins’ peer-to-peer information-sharing network. The Zooza product is a two-layer thermochromic paint that encourages community-driven mural events. The first layer consists of micro-cellulose scales, and pigment capsules in the second layer dissolve in response to a rise in heat, allowing the bright white cellulose scales in the first layer to return to fully saturated color. The solution adapts to the seasons, heating and cooling when necessary to lower demand for energy, and mitigates the effects of Urban Heat Islands. (Savannah, GA, USA)
“We aim to inspire the community to think creatively about how and where to apply the paint. While our solution begins on walls, the possibilities expand to other surfaces, such as benches, bus stops, railings, and more. We hope that in the future, buildings, cars, and all types of city elements change with the weather to better adapt to the growing concerns of climate change. Even more importantly, we hope this shift evolves from the decisions and voices of the most vulnerable communities.” — Team Zooza
