Biodegradable Pots as Circular Alternative to Plastic Containers
Biodegradable Pots is a material research project addressing the widespread use of plastic containers in horticulture, floriculture, and gardening. In response to the environmental impact of single-use plastics, the project proposes an alternative production model aligned with the United Nations Sustainable Development Goal 12: Responsible Consumption and Production. The research focuses on waste reduction, material reintegration, and circular design strategies through the development of biodegradable plant containers.
The project investigates the reuse of organic waste from three primary sources: discarded natural fibers and plant matter from floriculture, food residues such as eggshells from restaurants, and wood waste, including sawdust, from carpentry workshops. Rather than being treated as disposable byproducts, these materials are repositioned as raw resources capable of re-entering the production cycle.

Adonis Evangelista Prototypes Organic Waste Into Plant pots
Collected materials were sorted, cataloged, dried, and processed as part of a series of experimental trials. Multiple material combinations were tested using different fabrication methods, including molding, industrial sewing, and folding techniques applied to biomaterials. Each iteration evaluated key performance criteria such as structural resistance, durability, water drainage, and compatibility with plant growth requirements.
The research by designer Adonis Evangelista, supervised by Lígia Lopes, emphasized the use of natural binders compatible with plant pH, ensuring that the resulting containers support healthy plant development while remaining fully biodegradable. Prototyping and testing demonstrated that organic residues could be effectively transformed into functional plant pots capable of replacing conventional plastic alternatives.

Reducing Plastic Dependency Through Circular Material Design
By converting organic waste into usable planting containers, the project illustrates how design-led material experimentation can contribute to reducing plastic dependency while supporting circular economy principles. The outcomes indicate a viable and scalable approach to biodegradable pot production, with potential for further development in material optimization, manufacturing processes, and production scale.
Through its focus on waste as a resource, the project contributes to more sustainable production and consumption patterns, positioning biodegradable materials as practical components within horticultural and gardening systems.
