You're referencing a fascinating idea, but currently there's no confirmed evidence that researchers at the University of British Columbia (UBC) have developed a biodegradable battery from tree pulp and zinc that decomposes naturally in soil within months as described.
I couldn’t find any reputable sources or academic publications—either from UBC or other credible outlets—supporting that specific claim.
A recent post on “Industree News” (dated August 3, 2025) details a biodegradable battery made from tree pulp and zinc developed by UBC. However, that appears to be from a blog, not a verified academic source or university announcement, and no peer-reviewed scientific paper or official release corroborates it.

UBC researchers have explored other green energy innovations, but nothing matching your description:
- Work on fruit-waste microbial fuel cells from UBC Okanagan aims to generate electricity—but this uses microbial processes and fruit waste, not tree pulp and zinc batteries.
- A UBC thesis studied zinc-ion batteries with coatings (Al‑O‑N) and hybrid electrolytes to improve stability—but that’s technical battery enhancement, not biodegradable, pulp-based designs.
Outside UBC, related innovations exist:
- Researchers in China turned paper-industry waste (cellulose & lignin) into components for zinc–air batteries, showing promising power density and cycling stability.
- Teams in Singapore (NTU) developed biodegradable paper batteries using zinc and manganese inks on cellulose paper that can compost in soil within a month—but again, not UBC.
- Other explorations include chitosan (from crab/lobster shells) with zinc electrolytes, and various wood-derived carbon anodes, but none match your exact description or location.

🌱 Powering the Future: Could Tree Pulp and Zinc Be the Key to Biodegradable Batteries?
As the world confronts the environmental consequences of modern technology, researchers and innovators are turning toward more sustainable alternatives—especially when it comes to batteries. Imagine a battery that powers your medical implant, wearable, or sensor for a few weeks or months, and then disappears—harmlessly—into the soil. No toxic waste. No recycling required. Just clean, biodegradable energy.
While not yet confirmed as a breakthrough at the University of British Columbia, the concept of a biodegradable battery made from tree pulp and zinc is grounded in real scientific possibility—and part of a broader wave of innovation in sustainable energy storage.
🌍 Why We Need Biodegradable Batteries
The batteries we use today—primarily lithium-ion—have revolutionized technology but left behind an uncomfortable legacy: e-waste. These batteries are difficult to recycle, require rare-earth metals, and can leach toxic chemicals into the environment if not properly disposed of. With billions of small devices—from fitness trackers to environmental sensors—being used globally, we’re facing a growing problem.
That’s where biodegradable batteries come in.
🌲 How Tree Pulp and Zinc Could Work
The idea centers around cellulose (a component of tree pulp) as a structural base and zinc as the active metal. Zinc is abundant, safer to handle than lithium, and already used in various battery types. When combined with a biodegradable substrate like treated cellulose, researchers believe it’s possible to create a battery that:
- Delivers reliable short-term power
- Naturally breaks down in soil within weeks or months
- Leaves no harmful residue behind
- Can be manufactured from renewable resources
This could be ideal for applications like:
- Medical implants (temporary pacemakers or biosensors)
- Environmental monitoring devices in forests or oceans
- Consumer wearables with limited lifespans
- Smart packaging or logistics trackers
🔬 What’s Happening in the Field Now?
Although UBC has not (yet) officially unveiled such a battery, similar research is underway globally:
- Nanyang Technological University (Singapore) has developed paper-based zinc batteries that decompose in soil within 30 days.
- Researchers in China have repurposed paper mill waste into zinc–air batteries.
- UBC Okanagan has worked on microbial fuel cells powered by fruit waste, showcasing the university’s commitment to clean energy innovation.
- Other institutions are experimenting with chitosan, a seafood-derived biopolymer, as an electrolyte.
These efforts suggest the potential for a cellulose-zinc biodegradable battery is real—it may just be a matter of time before someone cracks the code.
🚧 Challenges Ahead
While the concept is compelling, real-world deployment will require solving key hurdles:
- Energy density: Can biodegradable batteries store enough power for broader applications?
- Shelf life and durability: Will they last in unpredictable environments?
- Cost and scalability: Can they be mass-produced affordably?
Until these questions are answered, biodegradable batteries are likely to remain focused on short-term or disposable electronics.
⚡ Final Thoughts
Whether it’s UBC or another forward-thinking research team, the quest for biodegradable batteries is heating up. The combination of tree pulp and zinc could offer a new kind of power—one that energizes our devices without compromising our planet.
In the near future, we may see batteries that grow from nature, serve their purpose, and return harmlessly to the earth. That’s not just innovation—it’s regeneration.

Bottom Line
- The concept—a biodegradable battery from tree pulp and zinc that dissolves harmlessly in months—is scientifically plausible and aligns with sustainable innovation trends.
- But the claim about UBC as the developer lacks credible backing at this time. It appears to stem from a non-peer-reviewed blog post without primary sources or official validation.
