Energy and bottles

Energy and bottle An interesting historical (1950s) example is the small injection blow molded whiskey bottles that were substituted for glass blown bottles in commercial aircraft continues to be used in all worldwide flying aircraft. At that time, just in USA, over 500 x 1012 Btu or the amount of energy equivalent to over 80 x 106 barrels of oil was reduced. 

Figure 1. Eigenvalues of the scaled champagne bottle Hamiltonian (Eq. (2)) for p = 0.00625, in the energy, , and angular momentum, k map. The eigenvalues, represented by points, are joined (a) by lines of constant bent vibrational quantum number, vt, and (b) by lines of constant linear quantum number, v = 2vt + k. ...

In 2004, the Ontario plant began to produces sports and energy drink bottles made from biodegradable NatureWorks PLA resin. 

Plastics make up only about 8 percent of the volume in the average landfill but represent a huge investment of energy and raw materials. Most plastics produced from petroleum materials by polymerization of monomers such as ethylene or vinyl chloride are thermoplastic materials and can be cleaned, melted, and re-formed. Thermosetting plastics can also be cut into pieces that are mixed with other plastics or used as fillers. High-density polyethylene (HDPE) and polyethylene terephthalate (PETE) are the most widely reused plastic materials, but polyvinyl chloride (PVC), polypropylene, and polystyrene account for 5 percent of the recycled plastics. In 2001 80 million pounds (36 milfion kilograms) of plastics were recycled in the United States. Recycled plastic materials are used in the production of bottles, fabrics, flowerpots, furniture, plastic lumber, injection molded crates, and automobile parts. 

If bottle A contains ci5-2-butene, bottle B contains 1 -propyne, and bottle C contains butane, identify the bottle that contains the compoxmd with carbon-carbon bonds of the highest bond energy. 

For example, LCA studies on identical poly(ethylene terephthalate) (PET) soda bottles produced at two plants can have very different embodied energies because their process electricity is derived from different sources (coal vs. hydropower) or because modes of transportation or the distances in the distribution networks are different or even because they use different disposal methods. Mechanical recycling, where available, can make a very significant differences to both the energy and carbon footprint of the product. A technically recyclable product should not be credited with saved energy in the LCA unless the infrastructure is actually present to recycle it.
