Circularity represents an innovative approach to sustainability, aiming to transition from linear systems to cyclical ones by minimizing waste and optimizing resource utilization. Key to this concept is the repurposing of waste into valuable resources, which not only reduces environmental impact but also fosters innovation and produces further value. By utilizing their own waste, organizations can not only decrease their ecological footprint but also promote the development of materials with enhanced circularity thus mitigating environmental harm. Embracing circular practices provides a tangible pathway towards harmonizing human activities with the natural world, nurturing a regenerative global ecosystem.
In a concerted effort to tackle biomass waste generated from JvEsch's operations, a strategic partnership with MNEXT is forged. This collaboration endeavours not only to replace unsustainable materials but also to enhance operational efficiency. Central to this initiative is a one-year research feasibility project which focuses on upcycling JvEsch’s biomass waste into valuable products for use in their business model. By examining JvEsch's waste streams, opportunities for the production of alternative materials were being explored. Among these materials, mycelium biocomposites (MBCs) emerge as a promising option for waste reduction and material innovation.
The primary objective of this project is to explore the viability of manufacturing and utilizing MBC plant pots using JvEsch's waste. Unlike conventional pots, these innovative alternatives eliminate the need for removal before planting. Through replacing traditional plastic pots commonly used in the industry, the investigation aims to practically demonstrate the transformative potential of circularity in waste management and material production within an organization.

Every year, thousands of plastic pots are used in landscaping and reforestation, which ultimately end up as waste. The MycoRenew project set out to provide a sustainable alternative by developing biodegradable plant pots from pruning and green waste, using the natural binding capacity of fungal mycelium.

In collaboration with landscaping company JvEsch and MNEXT, researchers and students converted local waste streams into strong, fully compostable pots. After testing mixtures of wood, grass and compost, a formulation was developed that combines durability with biodegradability. The pots can be planted directly in the soil, leaving no plastic behind.

The innovation has drawn the interest of Rijkswaterstaat, who will test the pots in a reforestation project once seasonal planting conditions allow. While production costs are still higher than those of conventional plastic pots, the project has demonstrated that waste can be upcycled into valuable circular products. The results have already inspired students, practitioners and public organizations, with knowledge shared through education, dissemination and regional media. MycoRenew therefore marks a concrete step towards a future in which local residues are turned into resources, and every tree is planted in a pot that gives back to the soil.
