PeelPack, an Italian-Swiss startup, turns discarded potato peels into compostable food containers. The innovation aims to replace conventional plastic trays used in fruit and vegetable packaging, reducing emissions and waste while extending produce shelf life.
Compostable food containers made from food waste
A new generation of compostable food containers could soon replace the plastic packaging commonly used for fruits and vegetables. While polymer trays play a key role in preserving freshness, they pose a major recycling challenge due to the large volumes of plastic involved.
This is where the Italian-Swiss startup PeelPack comes in.
The company has developed an innovative process that transforms discarded potato peels into fully compostable packaging.
The idea originated at ETH Zurich, where Massimo Bagnani, a biomedical engineering graduate from the Politecnico di Milano, was completing his PhD. Thanks to the FoodSeed acceleration program, the concept returned to Italy for industrial development.
How PeelPack creates its compostable containers
The process begins with the massive quantities of potato peels discarded by the snack industry. These are processed, dried, and mixed with other strictly natural ingredients to form a compostable material. Through thermoplastic and thermoforming techniques, PeelPack produces biodegradable containers durable enough to hold fruits and vegetables.
This approach perfectly embodies the principles of the circular economy, creating a bioplastic alternative that could reshape Europe’s packaging market.
The advantages of PeelPack’s technology
PeelPack’s compostable material offers several environmental and economic benefits. It helps reduce emissions from fossil-based polymers, cuts microplastic pollution, and lowers dependency on imported bioplastics. If scaled up to industrial production, this innovation could allow Europe—and particularly Italy—to lead domestic manufacturing of compostable food containers, using a proprietary technology that directly repurposes agricultural waste.
Another major advantage compared to traditional plastic trays is extended shelf life. Fruits stored in PeelPack containers remain fresh longer, avoiding mold growth that typically appears within five days in standard packaging.
The containers’ unique breathability prevents moisture buildup, inhibiting the development of fungi and bacteria.
PeelPack now aims to relocate production to Italy under a circular economy model that cuts manufacturing costs, lowers greenhouse gas emissions, and minimizes overall environmental impact.
