Practicing Stewardship

• Renewable resources are the materials that can be replaced or replenished over a reasonable amount of time.
• Nonrenewable resources are those that cannot be replaced or replenished over a reasonable amount of time.
• hydrocarbus - carbon and hydrogen compounds
• The three forms of fossil fuels are natural gas, crude oil or petroleum and coal
• Distillation is the process of evaporating a liquid and then cooling the steam at a certain temperature to condense it into its pure substance
• Coal 


  Made up of plants such as ferns and trees; Highly combustible rock made mostly of carbon
• Natural Gas 


  Made up of zooplankton and algae; Mostly made of methane, use din power plants
• Crude Oil or Petroleum


  Made up of zooplankton and algae ; Yields different products once distilled
• Propene,Propane & Butane


  Propene is combined with other chemicals to make anesthetics and polypropolene
• Gasoline-blending components (28*C - 85*)


  Products include fuel injector cleaners and ethanol
• Naptha (85*C - 177*C)


  Light Naptha produces paraffin wax, which is used in crayons, candles, beauty treatments, lubrication and electrical insulation; Heavy Naptha is crucial in the production of plastics
• Kerosene(177 - 232*C)


  It is used in camping stoves and jet fuels
• Diesel (232 - 343*C)


  It is used as fuel in diesel engines such as trucks and buses
• Lubricating Oils (343 - 566*C)


  This is used in forging and in making laxatives and petroleum jelly
• Residual fuel oil (>566*C)


  It is used as fuel for ships and some power plants
• Residual after the processing of crude oil


  Bitumen is used for road construction and roofing
• Concrete is a mix of water, aggregate (sand and gravel), and cement
• Cement is made up of certain proportions of materials such as calcium, silicon, aluminum and iron.
• Bitumen is a black sticky petroleum product made of a polycyclic hydrocarbon that has to be heated to hold teh aggregates together.
• Glass is much heavier and more difficult to color.
• Silicon dioxide is also used in making fiber optics for cables, fiberglass, and signanges.
• Liquefied Petroleum Gas (LPG)
• Polyester or polyethylene terephthalate comes from the chemical reaction of petroleum, air and water
• Petrochemicals are also by-products of petroleum
• sodium laureth sulfate (SLES)
• Sustainability means not just providing for the needs of today but also considers how the future generations will live.
• Water Footprint is the measure of the amount of water needed to make a certain product.
• Sustainability Science is a relevant emerging field of research that studies the interactions between natural and social systems and how these interactions affect the challenge of sustainability
• Asphalt is made up of 95% aggregate (crushed stone, gravel and sand) and 5% bitumen
• STRAWW - Soil, Trees, Air, Water, Wildlife
• CMON - Coal, Minerals, Oil, Natural Gas
• Soap is made up of fat treated with an alkali that has cleaning properties. Detergent are extensively use din all forms of cleaning products and are made out of petrochemicals.
