Gasoline was once a byproduct of oil refining that later became a desirable commodity as motor fuel. The plastic used in plastic shopping bags also started as a by-product of oil refining. [1] By-products are sometimes called co-products to indicate that although they are secondary, they are desired products. For example, hides and leather may ...
Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP.One example of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration.
Examples of reused waste is milled asphalt can be used again for the asphalt mixture or fill dirt can be used to level grade. Hazardous waste The EPA defines hazardous waste as "a waste with properties that make it dangerous or capable of having a harmful effect on human health or the environment."
Past studies show that microplastics — extremely small pieces of plastic that are either manufactured or a byproduct of the breakdown of larger plastic items — are not only ... for example ...
Waste heat is heat that is produced by a machine, or other process that uses energy, as a byproduct of doing work. All such processes give off some waste heat as a fundamental result of the laws of thermodynamics. Waste heat has lower utility (or in thermodynamics lexicon a lower exergy or higher entropy) than the original energy source.
The formation of carbon dioxide – a byproduct of ethanol fermentation – causes bread to rise. Ethanol fermentation causes bread dough to rise. Yeast organisms consume sugars in the dough and produce ethanol and carbon dioxide as waste products. The carbon dioxide forms bubbles in the dough, expanding it to a foam.
A good example is steelmaking slag: quicklime (CaO) and magnesite (MgCO 3) are introduced for refractory protection, neutralizing the alumina and silica separated from the metal, and assisting in the removal of sulfur and phosphorus from the steel. [citation needed]
He sees Trump's second term as the byproduct of an increasingly win-at-all-costs political climate that will persist for decades to come − and perhaps alter or upend the ceremonial visits ...
