GREEN TECHNOLOGY
DEFINITION
• To reduce contaminant and harmful process
• Environmental friendly technology that doesn’t disturb the environment and conserve natural resources.
TYPES OF GREEN TECHNOLOGY
• Green chemistry
• Green Nanotechnology
• Green Building
• Green Information
• Green Energy
GREEN CHEMISTRY
• Also called Sustainable chemistry
• A philosophy of chemical research and engineering that encourage product design and process that minimize the use and hazardous substance generation
• Ex: Herbs used in cosmetic and medicine products
GREEN NANOTECHNOLOGY
• Producing nanomaterial and product without harming the environment or human health.
• Nano-product or nanomaterial without toxic ingredients, at low temperature, using less energy, and renewable inputs.
• Ex.: Light-emitting diodes (LEDs) lamp
GREEN BUILDING
• Eco friendly structure and construction process.
• All building cycle: design, construction, maintenance, renovation and demolition.
• Ex.: material: low VOC paint, paper insulation panels, cotton batt insulation, woven wool carpeting, ecological concrete.
GREEN INFORMATION AND TECHNOLOGY
• Reduce the carbon footprint generation
• Design and product uses for reduce the negative impact to human.
• Ex.: LCD monitor (Samsung and Dell);
GREEN ENERGY
• Energy produced by natural sources; sunlight, wind, rain, tides, plants, algae and geothermal
• Green company: Intel (uses 51% renewable sources energy); Cisco (telecommuter communication to reduce transportation cost); Dell (GHG emission by 40% by 2015)
GREEN MANUFACTURING
GREEN MANUFACTURING
“To prevent pollution and save energy through the discovery and development of new knowledge that reduces and/or eliminates the use or generation of hazardous substances in the design, manufacture, and application of chemical products or processes.”
