The Biomimicry Institute has revealed this year’s 10 Biomimicry Global Design Challenge finalist teams, which have created innovative solutions for sustainably tackling global issues. The proposals, which all take inspiration from nature, address one or more of the United Nations’ 17 Sustainable Development Goals. The 10 finalists were selected from over 81 student teams as well as 26 teams of professionals from 17 countries in total.
Of the 17 United Nations Sustainable Development Goals, half of the 2020 Biomimicry Global Design Challenge submissions addressed “Sustainable Cities and Communities”, and over one-quarter addressed either “Good Health and Well-being”, “Climate Action”, “Life Below Water” and “Clean Water and Sanitation.” This year’s 10 finalist teams are from five different countries — including Australia, Canada, the Netherlands, Taiwan and the United States — with the majority focused on Good Health and Well-being, Sustainable Cities and Communities and Climate Action.
The first five finalists in alphabetical order include A Sensitive Wall, a proposal for a dynamic green noise barrier for reducing the urban heat island effect and traffic noise. It takes inspiration from concave-eared torrent frogs, mimosa leaves and desert snails. BottleBricks is an interlocking bottle system for insulating refugee housing that mimics the air-trapping qualities found in the triangular, corrugated shape of Saharan silver ant hairs and the structure of silk cocoons.
ELIGHTRA is a solar-powered lighting system for temporary settlements with hard outer shells like a ladybug’s elytra (wing cases). Methanolite is a methanotroph-inspired method for converting methane into methanol without carbon dioxide emissions. MyOak Public Market is an online platform to increase food access for vulnerable populations during times of crisis; the project takes cues from the Chesapeake Forest.
Additional finalists include nutriBarrier, a woven barrier for reducing nutrient runoff inspired by the protective strategies of hagfish and frogs. The floral stamen-shaped air filtration system Pranavayu features the electrical and structural properties of a spiderweb. An air filter called RICOCHET mimics mantas. The SINC (Sustainable Ice Nucleation Contraption) outdoor water collection system improves access to clean drinking water with methods similar to the countercurrent heat exchange system found in trout. Tubes, Blades, Mesh, Oh My! is a seawall retrofit proposal that takes cues from seagrass and mangroves for greater coastal resiliency.
