When reviewing the Supply Chain design for DEP/GARD‚ there are various stages which add value‚ and some which fail to add value. Looking at figure 1. below‚ you will see the diagram outlining the supply chain value stream enabling DEP to delivery product to GARD. Areas which fail to add value‚ and have the potential to erode DEP’s ability to remain a valued supplier for GARD include the following: 1. Failure to utilize LEAN manufacturing principles causing DEP to carry excess inventory: Inventory

RECYCLING Recycling is a process to change materials (waste) into new products to prevent waste of potentially useful materials‚ reduce the consumption of fresh raw materials‚ reduce energy usage‚ reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal‚ and lower greenhouse gas emissions as compared to plastic production.[1][2] Recycling is a key component of modern waste reduction and is the third component of the "Reduce

Chromatography paper‚ and paper in general‚ is very hydrophilic. Paper is made from a natural polymer called cellulose‚ which is a long chain of glucose molecules. Glucose is a cyclic structure with a number of -OH groups around the ring. a. Predict and explain the types of IMFs that would occur between paper and water. How do these interactions

Matrix-assisted laser desorption/ionization (MALDI) is a soft ionization technique used in mass spectrometry‚ allowing the analysis of biomolecules (biopolymers such as DNA‚ proteins‚ peptidesand sugars) and large organic molecules (such as polymers‚ dendrimers and other macromolecules)‚ which tend to be fragile and fragment when ionized by more conventional ionization methods. It is similar in character to electrospray ionization both in relative softness and the ions produced (although it causes

As mentioned before‚ browning in bananas is an enzymatic process where enzymes such as polyphenol oxidase serve as catalysts in the oxidation of several phenolic compounds. In this experiment however‚ the only reaction being tested is the oxidation of catechol (a diphenol) by the enzyme catalyst catechol oxidase or polyphenol oxidase‚ which initiates a chain of reactions and eventually triggers the formation of brown pigments known as catechol-melanins. Catechol‚ also called 1‚2-dihydroxybenzene

of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants‚ many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%‚ that of wood is 40–50% and that of dried hemp is approximately 45%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative

influence that rubber particle size exerts on the rheological properties of these binders has been studied. The resulting viscoelastic behaviour has been compared with that shown by unmodified and polymer-modified (SBS) bitumens. In total‚ an unmodified bitumen‚ five ground tire rubber-modified and three polymer-modified (SBS) bitumens have been studied. Rubber-modified bitumens show improved viscoelastic characteristics and‚ therefore‚ higher viscosity than unmodified binders. Consequently‚ enhanced resistance
