In this landscape, expandable polystyrene (EPS) is the dominant choice; however, the waste management of EPS is hampered by recycling challenges and lack of economic incentives. Concurrently, the order delivery and pharmaceutical distribution have experienced significant growth due to lifestyle shifts after the pandemic. For instance, the utilization of drones for transportation is illustrated (see abstract figure) as a prospective alternative transportation protocol. In this work, a synthetic method is developed to prepare bio-degradable thermal insulator material from recycled wood and silica aerogel. The silica aerogel wood composite (SAWc) has the following properties: 1) low carbon emission (4.932 kg CO2e kg−1); 2) low thermal conductivity (0.032 W mK−1) with an anisotropy of 1.5; 3) high compressive strength (yield stress = 8.60 Mpa); 4) excellent resistance to organic solvents; 5) high biodegradability (49.4% weight loss after 28 days); 6) excellent flame retardancy, both of which are above EPS. The scalable, super-insulating, and robust thermal insulator, as demonstrated in this work, holds high potential as an alternative packaging material poised to shape the next era in thermal insulation solutions. |
