Asif Khan and Biomason explore ecofriendly biocement

When London-based designer Asif Khan and American cement industry innovator Biomason joined forces to collaborate on a Wallpaper* Re-Made project for 2020, their explorations led them to ‘Coral Reef’, a shelving unit built from ingots of biocement. The design was partially inspired by one of Khan’s ongoing architecture projects in the UAE, the new Museum of Manuscripts in Sharjah, which is due to be completed in 2022.

It also addressed issues around locality, sustainability and functionality, drawing on Biomason’s bioLITH tile format and the company’s technique of ‘growing’ ecofriendly cement using microorganisms – just as coral reefs are formed in marine environments (hence the product’s name). The tiles developed for ‘Coral Reef’ would be made using sand from Sharjah, leading to a design that is conceptual but also pragmatic, and intrinsically connected to nature. The goal? To open up new paths in material use for the architecture and design industry.

North Carolina-based Biomason, co-founded by CEO Ginger Krieg Dosier and her partner Michael Dosier, has developed an aggregate mixed with microorganisms that is pressed into shape, fed an aqueous solution, and hardened to specification in order to form innovative, biologically controlled structural cement. ‘Our biocement is revolutionary, with low carbon emissions, and has the ability to be used throughout the built environment, not just in tiles,’ explains Krieg Dosier. ‘Annually, the production of Portland cement accounts for eight per cent of global emissions. Portland cement is ubiquitous, and the production is demanding incredible sacrifice from our planet. It is time for society as a whole to be aware of Portland cement’s carbon emissions. Biomason has a proven solution that taps into nature’s closed-loop system and that does not depend upon emitting carbon to create concrete components that are beautiful and strong.’

Biomason first developed its technology in 2009 in Sharjah, so the project neatly brought the company full circle. Expanding its abilities was enticing, and although not entirely straightforward, it has been a welcome challenge for the team, which has a keen eye for opportunity. ‘An early concept specified bioLITH tile vertical structural elements connected with an alternate material as horizontal elements,’ recalls Biomason product designer Thomas Hill. ‘Unconventional fabrication and joinery pushed the limits of the bioLITH tile. While relying on the tile alone to provide structure was not successful, it presented avenues for further exploration into form and function for future products.’

Now, its design finalised and the prototype built in Khan’s east London workshop with the help of the studio’s Isabella Stone-Wilson and Alex Borrell, ‘Coral Reef’ is an elegant, tactile structure that alternates bioLITH tiles made using Sharjah sand and wooden slats.

The latter help provide structural support, but there’s a strong conceptual base to this material blend, too. The Sharjah sand tile ‘represents the future’, says Khan. He likens the sample to something that offers a glimpse of what industry innovation looks like, a ‘relic from the future’, which balances dramatic change with a familiar, organic character and feel. ‘It is an amazing material. The design’s formal language may be based on the Sharjah museum and closely matches the current Biomason product, but we worked more conceptually with it, and treated it as a fragment of a coral reef or a precious material or geological matter. We also wanted to expand the product’s qualities and personality. We chose to match it with wood, so you have a juxtaposition of a natural material with a kind of “man-made” nature. It is a composition of two forms of nature.’

This poetic balance, together with its modular design and fluid function (it could be anything, from a bookshelf to a display case or screen), make ‘Coral Reef’ an exciting piece; and, the team agrees, it could be just the beginning. Further explorations could include ‘looking at more complex forms and modular biocement components that could lend self-supporting structure’, says Hill. Also, going bigger and experimenting with larger scales – a pavilion, for example – feels like an apt next step to Khan, who says: ‘We’d love to create a whole Biomason building one day.’
