Transcript of "The five subsectors of green product development and manufacturing"
1. Green Manufacturing <br />“Green manufacturing involves making manufactured products and the manufacturing process safer for the environment and human health” (Cha). <br />What does this mean? <br />Regarding Products<br />The use of less toxic or nontoxic materials<br />Post-consumer recycled content (containing materials that consumers have used and recycled)<br />Locally sourced materials (ex. Stone and granite from local quarries rather than imported from around the globe)<br />Products manufactured and used in renewable and energy efficient systems (ex. Gearboxes used in small-scale wind turbines)<br />Regarding Process<br />Improving operational energy efficiency<br />Onsite recycling <br />Employee occupational health and safety<br />
1. Green manufacturing (continued)<br />Local Example:<br />Tri-State Biodiesel, Bronx<br />Vision:<br />“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.”<br />Image courtesy of : http://www.tristatebiodiesel.com/<br />
Green Manufacturing in action<br />The TSB Process<br />1.) Waste oil from restaurants is emptied into large steel storage barrels<br />2.) A TBS representative comes to siphon the used oil into a collection tank<br />3.) Oil is processed to remove dirt, food particles, and water<br />4.) Purified oil feedstock is transported to aBiodieselfacility where methanol, sodium methylate, and heat are added causing a chemical reaction called Transesterification<br />5.) Transesterification yields mono-alkyl esters or Biodiesel<br />6.) Hence, the heater that warms you or the car you drive could be fueled byBiodieselmade from recycled vegetable oil<br />Baker, Brent.

2. Deconstruction<br />“Deconstruction is the process of carefully dismantling and removing useable materials from structures for reuse, recycling, and waste management” (Cha). <br />Advantages: <br />Maximizes the recovery of valuable building materials for reuse and recycling<br />Minimizes the amount of waste destined for landfills<br />Alternative to demolition<br />“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”<br />EPA Report: Beneficial Use of Secondary Materials – Construction and Demolition Materials<br />
2. DECONSTRUCTION (CONTINUED)<br />Example: <br />Susquehanna Deconstruction Pilot Project<br /><ul><li>Deconstruction pilot project to determine cost-effective methods for removing lumber and other valuable materials
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.</li></ul>Experiment with “paneling,” large sections of row houses are removed intact for disassembly and reuse. <br />Unique architectural features such as a corner turret and radiators are retrieved from urban row houses and sold through local salvage business. <br />Images courtesy of OSWER Innovation Project Success Story: Deconstruction<br />
3. Reuse<br />“This subsector redistributes unwanted yet perfectly usable materials and equipment, including items from demolished structures” (Cha). <br />Advantages<br />Keeps goods and materials out of the waste stream<br />Advances source reduction<br />Preserves the ‘embodied energy’ originally used to manufacture an item<br />Creates less air and water pollution than making a new product or recycling<br />Saves money in purchase and disposal costs<br />
4. Recycling<br />“Recycling is the collection, sorting, and reprocessing of used material into new raw materials” (Cha). <br />Image courtesy of: http://www.newrockford-sheyenne.k12.nd.us/activities/groups/nhs/Recycling<br />
5. Remanufacturing<br />“A process of disassembling worn-out or discarded equipment, recovering sound and usable parts, and reusing them to build new, complete products” (Cha). <br />Advantages: <br />Promotes reuse and waste prevention<br />Discourages the use of virgin materials<br />
