Extract of sample "Materials economy"

One of the problems with this materials economy is massive amount of energy inputs necessary along each step of the linear process. The energy usedin extraction alone is massive. Much of this energy is of a non-renewable variety; therefore, what you have is lots of cost and energy consumption that may be hidden from the end user of the material good. For example, a person that buys a cotton shirt made in Bangladesh is probably unaware of the amount of chemical fertilizer necessary to grow the cotton plant, the amount of petroleum needed to harvest the cotton and transport it to the mill. They are not thinking about the electricity needed to weave the cotton into fabric or to cut and sew the fabric into a shirt. They are not thinking of the diesel fuel used by the cargo ship that brought it from Bangladesh and the truck that delivered it to the mall. All of these energy inputs are hidden from the consumer in the material economy. That is why we so often dispose of a cotton shirt so readily after it is snagged or gets a small stain. If we really understood the inputs all along the way and how they effected the environment, we would dispose of things less readily. The other major problem with the material economy is the fact that it is an open system, not a closed system. Raw materials start at one end and waste products exit at the other end. This type of linear system sooner or later will run out of the raw materials needed to keep the system going. In a word, it is unsustainable in the long run. The system must be modified by changing it from a linear to a circular system of usage instead of consumption. This will ensure that the raw materials are not depleted at the extraction end. It will be replaced by recycling after usage. Disposal will be eliminated. Read More

...? Mechanical testing Lab report Introduction. Tension test is considered to be a basic category of mechanical test that can be permed on a material. Such a test is proven to be inexpensive, simple, and extremely standardized. Through pulling on something one will quickly be able to find out how a material can react to different forces that are applied to the tension. When the material is pulled, one would be able to establish the strength of the material. In this regard, tensile testing can help one to develop an insight into various substances. Whenever one continues to pull on a material, the material will break hence one would get a...

Hazardous Materials

...Running Head: SKIP NAVIGATION LINKS Skip Navigation Links Hazardous materials (HAZMAT) are the materialsthat pose as a threat to the environment or human health if released in large amounts. Incidences related to hazardous materials are normally complex in the public safety industry. Some of the risks that may arise due to the use of hazardous materials are; a fire hazard, an explosion, threat or a chemical gas threat. They occur due to the logistics involved in the response and operations that have to do with the way multiple units function at a scene .The multiple functions involve contraction and expansion as well as due to weather changes. The factors that are used in evaluating...

...Chemistry 14 November Materials in Green Cement The largely used construction material globally is Portland cement with an annual production of about 12 billion tones. However, its production utilizes vast amounts of raw materials such as limestone and sand, liberating a ton of carbon dioxide gas per ton of cement produced (Shah & Wang 15). The current focus on sustainable development in concrete technology aims at producing more environmentally friendly cement, which spawns less carbon dioxide and expends less energy. Such environmentally favorable cement is what is referred to as “green cement.” This paper focuses on the advancement of “non-clinker green cement” through the utilization...

...MATERIALS FOR CONSTRUCTION Registration Number: In this case, we are going to compare two structures. We have structure A and structure B. structure A is a 500 slab. This slab is 30 cm thick, so the total volume of the slab is 150. This structure has a tidal zone of San Diego. This is the reason why the structure has constructed using quite a strong mixture. On the other hand we have structure B which is a 800 circular column with a thickness of 50 cm. the total volume for this structure is 400. The analysis period for this structure is similar to that of the above structure. This structure is also exposed to the tidal zones of Miami. The main differences occur in the mixtures that were made and used in the construction...

...Engineering and Construction Materials Markillie highlights the role of digital transition in the manufacturing sector and the third industrial revolution. Manufacturing tools are undergoing changes in a manner that will transform the nature of work in the sector. Past engineers used drills and moulding machines in manufacturing processes. Current engineers, however, apply automated machines in undertaking manufacturing works. Old machines are no longer applicable in the manufacturing process; automated machines outdo the role of old machines. Markillie emphasizes on the introduction of 3D printers among other new automated set of machines applied in manufacturing (1). 3D printers are efficient and simplifies most...

The innovation can be made at first twostages of carpet life cycle (i.e., Raw materials, processing the raw material). If we just have to educate farmers in the particular context. If farmers would be educated with regard to this technological advancement, we can directly start the life cycle for manufacturing of carpet from third stage (i.e., combine ingredients) and so on. ii. Technological advancement practicing: Researchers have now developed an enzyme-based biological technology that paves the way for manufacturing carpets that are much lighter, sustainable, biodegradable, and 100%...
