  • 1. 1. Green Manufacturing
    “Green manufacturing involves making manufactured products and the manufacturing process safer for the environment and human health” (Cha).
    What does this mean?
    Regarding Products
    The use of less toxic or nontoxic materials
    Post-consumer recycled content (containing materials that consumers have used and recycled)
    Locally sourced materials (ex. Stone and granite from local quarries rather than imported from around the globe)
    Products manufactured and used in renewable and energy efficient systems (ex. Gearboxes used in small-scale wind turbines)
    Regarding Process
    Improving operational energy efficiency
    Onsite recycling
    Employee occupational health and safety
  • 2. 1. Green manufacturing (continued)
    Local Example:
    Tri-State Biodiesel, Bronx
    “TSB believes that the use of sustainably produced biodieselin combination with demand reduction measures such as mass-transit and transportation alternatives and in concert with technological advances such as diesel hybrids and light rail systems, can create an America that is both energy independent and sustainable.”

  • 3. Green Manufacturing in action
    The TSB Process
    1.) Waste oil from restaurants is emptied into large steel storage barrels
    2.) A TBS representative comes to siphon the used oil into a collection tank
    3.) Oil is processed to remove dirt, food particles, and water
    4.) Purified oil feedstock is transported to aBiodieselfacility where methanol, sodium methylate, and heat are added causing a chemical reaction called Transesterification
    5.) Transesterification yields mono-alkyl esters or Biodiesel
    6.) Hence, the heater that warms you or the car you drive could be fueled byBiodieselmade from recycled vegetable oil

  • 4. 2. Deconstruction
    “Deconstruction is the process of carefully dismantling and removing useable materials from structures for reuse, recycling, and waste management” (Cha).
    Maximizes the recovery of valuable building materials for reuse and recycling
    Minimizes the amount of waste destined for landfills
    Alternative to demolition
    “A typical 13,300 square foot commercial demolition project generates over 155 pounds per square foot or over 2 million pounds of waste;2 building-related projects in the U.S. alone generate an estimated 164 million tons of construction and demolition (C&D) material every year. Approximately 40% of this material is reused, recycled, or sent to waste-to-energy facilities, while 60 percent is sent to C&D landfills”
    EPA Report: Beneficial Use of Secondary Materials – Construction and Demolition Materials
    Susquehanna Deconstruction Pilot Project
    • Deconstruction pilot project to determine cost-effective methods for removing lumber and other valuable materials
    • 6. The project successfully demonstrated that deconstruction can be cost-competitive with hand demolition when there are sufficient recoverable materials to offset the high labor costs.
    Experiment with “paneling,” large sections of row houses are removed intact for disassembly and reuse.
    Unique architectural features such as a corner turret and radiators are retrieved from urban row houses and sold through local salvage business.

  • 7. 3. Reuse
    “This subsector redistributes unwanted yet perfectly usable materials and equipment, including items from demolished structures” (Cha).
    Keeps goods and materials out of the waste stream
    Advances source reduction
    Preserves the ‘embodied energy’ originally used to manufacture an item
    Creates less air and water pollution than making a new product or recycling
    Saves money in purchase and disposal costs
  • 8. 4. Recycling
    “Recycling is the collection, sorting, and reprocessing of used material into new raw materials” (Cha).
    Image courtesy of:
  • 9. 5. Remanufacturing
    “A process of bringing the used products back to ‘as new’ condition by performing the necessary operations such as disassembly, overhaul and replacement” (Fleishman et al.)
    • Promotes reuse and waste prevention
    • 10. Discourages the use of virgin materials
    • Auto Industry (Chrysler, Ford, GM
    • 11. Electronic Industry
    • 12. Tire Industry
    A typical unit (a product or a part) flow in remanufacturing (Gungor et. al.)
