What is a lightweight and strong renewable material obtained from plant matter?

The correct answer, nanocellulose, refers to a lightweight and strong renewable material derived from plant fibers. Nanocellulose is composed of cellulose, which is a natural polymer and the primary structural component of plant cell walls. This material is notable for its excellent mechanical properties, including high tensile strength and stiffness, while maintaining a low density.

Nanocellulose can be extracted from various plant sources, such as wood, cotton, and agricultural waste. It has applications ranging from biodegradable packaging materials to advanced composites and reinforced materials, making it a versatile component in sustainable engineering and product design.

In addition to being renewable, nanocellulose is also environmentally friendly, as its production can utilize biomass that would otherwise go to waste. This positions nanocellulose as an attractive option for industries looking to reduce their reliance on non-renewable materials and lower their environmental impact.
