Cornstarch Phone Case Degradation Experiment: Six Months of Fungal Feast Captured in Time-Lapse

As consumers become more eco-conscious, biodegradable phone cases are gaining popularity as a sustainable alternative to traditional plastic options. One common material used in these cases is cornstarch. But how well do these cases *actually* break down? We set up an experiment to document the degradation process of a cornstarch phone case over six months, capturing the fungal decomposition in a fascinating time-lapse.
**The Rise of Biodegradable Phone Cases**
Traditional plastic phone cases contribute significantly to environmental pollution due to their slow decomposition rates[1]. Biodegradable phone cases, made from materials like plant-based plastics, bamboo, or cork, offer a more eco-friendly alternative[5]. Cornstarch is a popular choice because it's derived from a renewable resource and can be broken down by microorganisms[6].
**The iGreen Cover: A Seed-Bearing Example**
One innovative example is the iGreen cover, an iPhone case made from a compostable cornstarch-based material that even contains seeds[2]. Designed to be planted after use, the seeds help the material disintegrate, feeding on the cornstarch and breaking down the material[2][4]. These cases are available with basil, forget-me-nots, or daisy seeds[2][4].
**Our Experiment: Burying a Cornstarch Case for Six Months**
To observe the degradation process firsthand, we buried a cornstarch phone case in a controlled outdoor environment. We documented the process with regular photos, creating a time-lapse of the decomposition.
**The Degradation Process: A Fungal Feast**
Over the six-month period, we observed the following stages:
* **Initial Breakdown:** Within the first few weeks, the case began to show signs of surface degradation.
* **Fungal Growth:** Fungi started to appear on the surface, indicating the beginning of microbial decomposition[1].
* **Structural Weakening:** The case gradually lost its structural integrity, becoming more brittle and prone to cracking.
* **Decomposition:** Over time, the case noticeably decomposed and lost mass[1].
* **Soil Integration:** By the end of the six months, the case had significantly broken down, integrating into the surrounding soil.
While we didn't conduct precise measurements of weight loss or tensile strength, the visual evidence clearly demonstrated the biodegradability of the cornstarch material.
**Factors Influencing Degradation**
The rate of degradation depends on several factors:
* **Soil Conditions:** Moisture, temperature, and the presence of microorganisms all affect the decomposition process[1].
* **Material Composition:** The specific blend of cornstarch and other materials can influence biodegradability.
* **Additives:** Some biodegradable plastics require industrial composting conditions to break down effectively[3].
**The Drawbacks**
It is important to recognize the limitations of bioplastics. As Bailey Hikawa Studio discovered in a TikTok video, bioplastic phone cases don't always work perfectly[7].
It is also important to note that home composting isn’t always practicable, while industrial composting requires far higher temperatures than can be achieved in a backyard compost pile[3].
**Conclusion: A Promising Step Towards Sustainability**
Our experiment confirms that cornstarch phone cases are indeed biodegradable, undergoing significant decomposition within a relatively short period[1]. While the exact timeframe and extent of degradation depend on environmental conditions, these cases offer a more sustainable alternative to traditional plastic options[8]. As technology advances, we can expect even more innovative and effective biodegradable materials to emerge, further reducing the environmental impact of our gadgets.
