The world’s forests are under threat.
Re-forestation is essential in the fight against climate change and to protect biodiversity, but planting saplings by hand can be slow and labor-intensive.
In recent years, drones have begun to be used to drop seeds onto land deforested by wildfires; a company called Mast Reforestation, formerly DroneSeed, has applied this method in the western United States and beyond, and World Wildlife Fund has used specialized drones to restore rural bushland in Australia. But for a reforest to regrow, dropped seeds have to get into the soil and germinate, and that can be a challenge.
Researchers from Morphing Matter Lab at Carnegie Mellon University, in Pennsylvania, might have an answer. Inspired by nature’s own design, the lab has created an “E-seed” carrier that is intended to be dropped by drones and drill into the soil.

Waste management and resource recovery remain essential to circular progress. The Department for Energy Security and Net Zero’s recent review identified strong potential for circular construction strategies and end‑of‑life reuse in construction to deliver quantifiable carbon savings. Yet challenges persist in the rollout of Simpler Recycling due to legacy property structures. Strengthening these back‑end systems ensures green building products re‑enter value chains, supporting both circular economy objectives and sustainable urban development. The collective impact across policy, design, education, and technology confirms that the carbon footprint of construction can be reduced dramatically when the sector treats sustainability as an integrated, measurable discipline rather than an optional ambition.
