Sustainable drawing tool developed at MOME wins award at the New York Biodesign Challenge

Date: 2024.07.10
Each year, 10 billion plastic pens are discarded worldwide, contributing to non-biodegradable waste that contains harmful chemicals, which can cause health issues if not processed properly. Despite this, coloured markers are indispensable for both schoolchildren and professionals in the creative industries. The pHen, an eco-friendly pen that won the Outstanding Art Award at the 2024 Biodesign Challenge in New York was developed by a student team from the Moholy-Nagy University of Art and Design (MOME) to address this issue. In addition to this accolade, the pHen team also secured a scholarship and an opportunity for an independent exhibition next year.

The team, consisting of Nóra Gulya, Csongor Boldizsár Nagy, and Szonja Somogyvári, comes from the diverse fields of Textile Design, Media Design, and Graphic Design. They began developing their revolutionary writing implement concept during a course. The tool is eco-friendly, versatile, appealing, promotes sustainable practices, and supports a circular economy with its refillable, multi-colour, non-toxic materials. 

  

So, how does it work? The pHen pens are innovative, sustainable markers that use pH-sensitive pigments derived from bacteria and vegetables, such as red cabbage. These markers change colour based on pH variations and are refillable, thereby reducing waste and eliminating harmful chemicals. 

  

The pHen is backed by research on pigments that change colour with changes in pH, using pigments found in bacteria and vegetables such as anthocyanins from red cabbage and actinorhodin from Streptomyces coelicolor to create sustainable inks. Since a single marker incorporates multiple colours, it offers more creative possibilities than traditional markers.The pen casing is designed to be open-source, allowing it to be produced in any fablab worldwide using a 3D printer, saving on shipping costs and making the design accessible to everyone. Their plans also include development of an adapter for 3D printers to support textile and graphic design. 

  

This year marks MOME's first participation in the prestigious Biodesign Challenge, where the team was among the finalists from over 500 students across fifteen countries. From September to spring, participants worked on perfecting their designs over two semesters with their course leaders, acting head of the Materials Research Hub, biodesigner, and material researcher Malu Lücking and workshop leader and art teacher Ferenc Kovács-Nagy. Their projects were then presented in mid-June in the final round in New York. 

  

The Biodesign Challenge aims to create an international knowledge-sharing platform for biodesigners, foster an active professional community, and promote biodesign technology among professionals.

Several students and staff members at Moholy-Nagy University of Art and Design recently reached important professional milestones and were warmly welcomed – alongside fellow attendees – at the 2025 Spring Title Award Ceremony by Acting Rector Csaba Kovács and Head of the Doctoral School Ábel Szalontai. This past semester, Bence László Dobos, Viola Fátyol, Henrietta Fiáth, Katalin Glaser, Gergely Hartmann, Flóra Kőszeghy, Piroska Novák, Panni Pais, and Valéria Póczos have earned their doctoral degrees, while Erzsébet Nagy, a long-standing and highly respected member of our textile programme, will receive the honorary title of Master Instructor.

The MOME 2025 graduation visual identity is now complete, offering a visual representation of community-driven future building. At MOME, it’s tradition for the visual identity of the diploma events – from graphic design to the portrait photography of BA and MA graduates – to be designed by students themselves, with the concept chosen through a competition judged by a panel of university staff. The annually revamped visual identity serves as a visual snapshot of its time.
