Biotic material or biological derived material is any natural material
Natural material
A natural material is any product or physical matter that comes from plants, animals, or the ground. Minerals and the metals that can be extracted from them are also considered to belong into this category.* Biotic materials...

The use of biotic materials, and processed biotic materials (bio-based material
Bio-based material
A bio-based material is simply an engineering material made from substances derived from living matter. These materials are sometimes referred to as biomaterials, but this word also has another meaning. Strictly the definition could include many common materials such as wood and leather, but it...

Alternative natural materials
Alternative natural materials is a general term that describes natural materials like rock or adobe that are not as commonly in use as materials such as wood or iron. Alternative natural materials have many practical uses in areas such as sustainable architecture and engineering...

, over synthetics is popular with those who are environmentally conscious because such materials are usually biodegradable, renewable, and the processing is commonly understood and has minimal environmental impact. However, not all biotic materials are environmentally friendly, such as those that require high levels of processing, are harvested unsustainably, or are used to produce carbon emissions.

When the source of the recently-living material has little importance to the product produced, such as in the production of biofuel
Biofuel
Biofuel is a type of fuel whose energy is derived from biological carbon fixation. Biofuels include fuels derived from biomass conversion, as well as solid biomass, liquid fuels and various biogases...

s, biotic material is simply called biomass
Biomass
Biomass, as a renewable energy source, is biological material from living, or recently living organisms. As an energy source, biomass can either be used directly, or converted into other energy products such as biofuel....
