Contrary to what the word may implicate, a biomaterial is not necessarily biological or based on bio-related matter. The material itself can be anything from a metal to a plastic to varieties of composites, but it can also be bio-inspired and derived from nature. The definition of a biomate...
Ideally, biomaterial should bebiocompatible, bioinert, bioactive, bioresorbable (biodegradable), bio-adoptable, and sterilizable(Fig. 8.8). The degree of the characteristics signifies the ability of the material for the biomedical application. What are biomaterials in engineering? Biomaterials is thefield...
What is Biodiesel?Biodiesel is a diesel-like biodegradable fuel. It is a non-toxic fuel produced from organic material. The organic raw material needed for producing bio-diesel use fatty substances. They include vegetable oils, waste cooking oil, animal fat and non-edible plant oils....
Clear definitions for "biobased" and "biodegradable" are needed to allow stakeholders of (bio)plastics to make fact-based decisions regarding material selection, application, and end-of-life options; the same level of clarity is needed for terms like "renewable carbon" and "bio-attributed" ...
The jury is still out on that one. Some say it uses about the same amount, because shaping starch-based material into cup form doesn't take any less effort than shaping fossil-fuel-based material into cup form [source:Teschler]. One point to remember here, though, is that companies in...
Focus on material transition and tier-two-supplier energy transition.Transforming fibers into garments—a fossil-fuel-heavy manufacturing process in many countries—accounts for around 70 percent of the industry’s emissions. Innovative, lower-cost green materials (such as cotton replacements, recycled ...
by the consuming organisms to derive energy, while the resulting CO2is returned to the atmosphere. However, much organic material enters the soils, waters and sediments in the environment either during senescence of plants or the excretions from, or death of, higher organisms. The deposition of ...
These sustainable feedstocks, such as waste oils and agricultural residues, absorb CO2 during their growth, which offsets emissions when the fuel is burned. This critical difference allows SAF to cut the lifecycle emissions of conventional aviation fuels by up to 80%, making it a vital component...
Plastic (ASTM D883): a material that contains as an essential ingredient one or more organic polymeric substances of large molecular weight, is solid in its finished state, and, at some stage in its manufacture or processing into finished articles, can be shaped by flow. ...
Plastic that is fossil fuel-based and non-biodegradable is what we know as conventional plastic. It takes centuries for most of these plastics to breakdown in the environment, and oil-derived plastics leave toxic byproducts in the soil or water. But if a plastic is biobased and biodegradable...
