TRANSCRIPT
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. DECONSTRUCTION
“Deconstruction is the process of carefully dismantling and removing
useable materials from structures for reuse, recycling, and waste
management” (Cha).
Examples and Advantages:
Maximizes the recovery of valuable building materials for reuse and
recycling
Minimizes the amount of waste destined for landfills
Alternative to demolition
Susquehanna project
experimenting with
“paneling,” where 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
Susquehanna architectural salvage business.

Project Success Story: Deconstruction
“Atypical 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”

Report, Waste and Materials Flow-Benchmark Sector Report: Beneficial Use of
Secondary Materials—Construction and Demolition Materials.
3. REUSE
“This subsector redistributes unwanted yet perfectly usable materials
and equipment, including items from demolished structures” (Cha).
Advantages
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
4. RECYCLING
5. REMANUFACTURING
