The rising costs of petrochemical feedstocks and an enhanced public desire for environmentally friendly green products have created a demand for these materials. [11] One of the most vocal supporters of these polyurethanes made using natural oil polyols is the Ford Motor Company , which debuted polyurethane foam made using soy oil in the seats ...
Building impacts belong to two distinct but interrelated types of carbon emissions: operational and embodied carbon.Operational carbon includes emissions related to the building's functioning, such as lighting and heating; embodied carbon encompasses emissions resulting from the physical construction of buildings, including the processing of materials, material waste, transportation, assembly ...
Examples of emerging bioproducts or biobased products include biofuels, bioenergy, starch-based and cellulose-based ethanol, bio-based adhesives, biochemicals, bioplastics, etc. [8] [9] Emerging bioproducts are active subjects of research and development, and these efforts have developed significantly since the turn of the 20/21st century, in ...
Moreover, they can be differently manufactured, [4] resulting in either simple or more complex engineered bio-products, which can be used for many applications. [11] Among processed materials, it is possible to distinguish between bio-based polymers , bio-based plastics , bio-based chemical fibres , bio-based leather , [ 12 ] bio-based rubber ...
Biodegradable polymers have a long history, and since many are natural products, the precise timeline of their discovery and use cannot be accurately traced. One of the first medicinal uses of a biodegradable polymer was the catgut suture , which dates back to at least 100 AD. [ 4 ]
The Alpena biorefinery plant in the USA. A biorefinery is a refinery that converts biomass to energy and other beneficial byproducts (such as chemicals). The International Energy Agency Bioenergy Task 42 defined biorefining as "the sustainable processing of biomass into a spectrum of bio-based products (food, feed, chemicals, materials) and bioenergy (biofuels, power and/or heat)". [1]
Biobased polymer derived from the biomass or issued from monomers derived from the biomass and which, at some stage in its processing into finished products, can be shaped by flow. Note 1 : Bioplastic is generally used as the opposite of polymer derived from fossil resources.
biobased products, such as food, feed, chemicals or other materials, and/or; bioenergy, such as biofuels, power or heat. A biorefinery is a facility like a petroleum refinery that comprises the various process steps or unit operations and related equipment to produce various bioproducts including fuels, power, materials and chemicals from biomass.
