Future Internet-of-things (IoTs) devices will reach 30 billion by 2030. The next 5-10 years will see a tsunami of e-waste due to billions of IoTs reaching their end of life. However, as an essential consideration for sustainability, end of life management has not yet been integrated into their current design. Conventional IoT devices comprise electronic and power components that are either difficult to recycle and degrade, or contain toxic/critical elements, thereby posing significant economic, regulation, environmental and public concerns. Furthermore, 100% recycling is not always possible due to extremely diverse application environments, locations and user convenience. This studentship aims to develop “zero waste” electronic and power components for future IoTs and portable electronics with built-in recyclability and biodegradability. The enabling of electronic and power components will be designed and developed to be both easier to recycle (e.g. separation of components by submerging under different solvents, heating, etc) and degrade into environmentally benign products (composts, harmless small molecules, environmentally friendly metals/salts) when discarded in the environment at end of life. The project encompasses the synthesis of green organic conjugated polymers within programmable degradation, the development of plant-based packaging and zero waste “transient” electronic/power components from low-cost biodegradable materials.
