A natural material is any product or physical matter that comes from plants, animals, or the ground which is not man-made. [1] [2] Minerals and the metals that can be extracted from them (without further modification) are also considered to belong into this category. Natural materials are used as building materials and clothing. Types include:
Although alternative building materials are a newer concept, some buildings have already employed these materials, as well as other tactics, in pursuit of greater sustainability. One such example is the School of Art, Media, and Design located in Singapore. This school has a roof made completely of grass (an example of Earth-sheltering). [4]

Earth materials include minerals, rocks, soil and water. These are the naturally occurring materials found on Earth that constitute the raw materials upon which our global society exists. Earth materials are vital resources that provide the basic components for life, agriculture and industry .
Use of natural biomaterials were used as early as ancient Egypt, where indigenous people used animal skin as sutures. A more modern example is a hip replacement using ivory material which was first recorded in Germany 1891. [57] Valuable criteria for viable natural biomaterials: Biodegradable; Biocompatible; Able to promote cell attachment and ...
Textile fibres or textile fibers (see spelling differences) can be created from many natural sources (animal hair or fur, cocoons as with silk worm cocoons), as well as semisynthetic methods that use naturally occurring polymers, and synthetic methods that use polymer-based materials, and even minerals such as metals to make foils and wires.
Nano-cellulose presented at low concentrations produces a transparent gel material. This material can be used for biodegradable, homogeneous, dense films that are very useful in the biomedical field. [7] Alginate: Alginate is the most copious marine natural polymer derived from brown seaweed. Alginate biopolymer applications range from ...
Isolating a natural product from its source can be costly in terms of time and materials, and may impact the availability of the natural resource or have ecological consequences. For example, it is estimated that harvesting enough paclitaxel for a single dose of therapy would require the bark of an entire yew tree (Taxus brevifolia). [124]
