FUNgi wall tapestry

bridging science and design through organic upcycling 

As a participant of Broei 2021, we want to throw back to the rich textile history of Flanders. As from the 14th century, Flanders played a significant role in the textile industry. Pieces of craftmanship were exported all over Europe, amongst which wall tapestries. These wall tapestries played a critical role within Medieval castle interiors, just like the interior of Geeraard de Duivelsteen where Broei will be taking place. By calling on this history, we will be contributing not only to the warm atmosphere of Broei but also the acoustics. Throughout several workshops, young people will bridge the gap between science and design. By painting with organic materials and the fungi weaving itself through the fabric, they create a valuable item from wastestream objects. In this way we want to open up new perspectives of a possible symbioses between science and design; and it's contribution to a more sustainable transition. 


Pilot Valorisation of Local Waste Streams

Semi open-source development

Each region has a unique waste landscape. Hier&na does active experimentation to determine what waste streams within the Flemish context could be valorised to replace existing carbon-intensive products. At present we are exploring three different areas: clothing, furniture, and lighting objects. Our solutions are open-source on the condition that the organisation(s) using them have signed our ethical charter. If you are interested in hiring us as consultants to explore the development of a product that fits within the circular economy context, do not hesitate to contact us!


Sustainable Burials

Reshaping burial practices in response to the climate crisis

In order to achieve carbon-neutral cities, regions, countries in the coming decades, many current practices must be questioned and made increasingly environmentally-friendly. The current Western burial practices are detrimental to both the environment and urban spaces. Graveyards occupy a non-negligible fraction of many cities' land area that could otherwise be converted into much-needed green spaces. Current burial practices also contribute to groundwater pollution in a time when water shortages are becoming increasingly prevalent. Cremation partly solves the land use issue but the such practices also contribute to air pollution. We have developed the concept of Reforestation through Burial that provides long-term solutions to many challenges faced by city councils. It provides a financially-sustainable option for cities to use natural burials to expand green spaces for its residents.
