Functional Unit (FU) = 1 year of 2.2 L per day (recommended daily intake for women) = 365 days, 2.2 L servings of water System Boundary: Study does not include impacts related to collecting, transporting and treating water. Does include weight of water during transport for plastic bottle. Plastic PET bottle reverse logistics—environmental performance of California’s CRV program 2012 In this paper, Brandon Kuczenski & Roland Geyer characterize the environmental burdens that result from a PET bottle in the CRV program being collected and recycled.

The Life Cycle of a Plastic Water Bottle Millions of bottles of water are purchased every year in the United States. Together with other plastic products, they play a ubiquitous role in the lives of several consumers. System boundaries are also set in the life cycle to determine the allocation of burdens and benefits regarding recycling. For instance, scrap is the output from the life cycle of steel drums and is used in another life cycle of perhaps a steel clamp ring of a drum. The boundary between the two life cycles
So how do the metals stack up against plastic? Drink bottles made from PP (code 5) are thicker, stronger and more durable than their PET (code 1) counterparts and are the material of choice for reusable plastic bottles. But like all plastics, they too are manufactured from a non-renewable resource derived from oil. Oct 08, 2013 · LIFE CYCLE STAGES: The Life Cycle Assessment then makes it possible to eco-innovate, i.e. create new glazing products, even more planet-friendly, from design stage to disposal. Life Cycle Assessment of Plastic: Plastic bags were first introduced in 1977 and now account for four out of every five bags handed out at grocery stores.
Domestic animals pictures pdfProduct rule worksheet exponentsSep 16, 2007 · A life-cycle assessment (LCA) study on various recycle routes of plastic materials has been conducted using the case of polyethylene terephthalate (PET) bottles as an example. The energy consumed and the emissions released during the entire life-cycle of the plastic material were accounted for using the energy and material balances on each stage of the life-cycle. A mathematical model ... Apr 25, 2011 · Coca-Cola conducted the first LCA in 1969 to assess the relative impacts of glass versus plastic bottles.1 Today, LCAs are used for a wide variety of purposes and, as such, can differ sharply in breadth and depth. The biggest differences stem from choices about the life cycle stage and types of impact: reduce harm to human health and marine life. The ban will ensure that drinking straws sold in England are made of more environmentally friendly materials that will decompose quicker and will have low life -cycle impacts on the environment. It will encourage businesses to invest in biodegradable alternatives to plastic.
Apr 25, 2011 · Coca-Cola conducted the first LCA in 1969 to assess the relative impacts of glass versus plastic bottles.1 Today, LCAs are used for a wide variety of purposes and, as such, can differ sharply in breadth and depth. The biggest differences stem from choices about the life cycle stage and types of impact: a 500 ml ―EcoShape‖ bottle2 and a 3 liter bottle, as well as sports drinks, vitamin-fortified waters, water directly from a tap, tap water from a filtering pitcher, water from a water vending machine, and tap water in three reusable bottle material types (aluminum, plastic and steel). Comparisons are also made of the environmental
