Sustainability is a growing priority in our industry and consequently, there is an increasing pressure to reduce environmental impact. One way to achieve significant reduction is to increase the share of biological materials. But how feasible is this shift from conventional plastics to more sustainable alternatives? At Genexis, we conducted a feasibility study to explore the potential of biomaterials in FTTH applications beyond packaging. Our goal was to assess both the technical and commercial viability of these materials. Our conclusion: widespread adoption seems currently unlikely— however, with sufficient interest, we believe there is an opportunity to further explore.
Testing biomaterials: what we learned
We experimented with different materials focusing on durability, processability, and market readiness. Some of the materials we tested included:
- Bamboo & cellulose-based materials: While promising from a sustainability perspective, these materials presented structural and processing challenges. It lacked the necessary durability and compatibility with existing FTTH requirements.
- Sugarcane-based materials: Among the options we explored, sugarcane-based materials showed the highest potential. It provided better mechanical properties and was almost commercially viable.
Through these injection mold trials, we gained valuable insights into the strengths and weaknesses of biomaterials for our sector.

The biggest challenges: why it’s not easy (yet)
Our exploration revealed several key challenges to adopting biomaterials in FTTH products:
- Market readiness: The industry is still heavily reliant on conventional plastics (virgin plastics but also recycled plastics). Biomaterials, while improving, are not yet a direct substitute in many applications.
- Technical limitations: Strength, longevity, and compatibility with existing infrastructure remain major concerns. Many biomaterials degrade faster than their traditional counterparts or require adjustments in manufacturing processes.
- Commercial feasibility: Supply chain constraints, production costs, and scalability challenges hinder the large-scale adoption of biomaterials.
Despite these obstacles, we believe that biomaterials can have a role in the future of FTTH — so we continue promoting and refining the concept.
While the transition to biomaterials in FTTH products is complex, it’s not a dead end. The key to success lies in collaboration. At Genexis, we are open to working with material innovators, manufacturers, and industry partners to explore viable solutions.
Our exploration reinforced the need for continuous innovation, investment, and joint efforts to develop biomaterials that meet both environmental and industry standards. The road ahead may be challenging, but sustainability in telecom is a journey worth pursuing. With the right partnerships and technological advancements, biomaterials can become more viable.
We invite stakeholders, industry leaders, and innovators to join us in this journey. Together, we can shape a more sustainable future.
