Additionally, the environmental implications of end-of-life disposal of encapsulant materials are currently highly uncertain but could play a significant role in the overall sustainability of the technology. Improving encapsulant longevity could make the beads less biodegradable and could have unintended consequences (e.g., to human health or biodiversity) if released into the environment without control. Strategies for reuse, recycling, or safe disposal of the beads should be developed in conjunction with improvement in the durability of encapsulant materials.
