- 3. Contents Green Technology Goals of Green Technology Types of Green Technology Power of Positive Green Benefits and Examples
- 4. Technology Application of knowledge for practical purposes. Green Technology “Use of science and technology in order to save natural environment.”
- 5. GOALS OF GRREEN TECHHNOLOGY Sustainability Cradle to cradle design Source Reduction Green Innovation
- 6. “Meeting the present needs of society without damaging or depleting natural resources.” Renewable resources should not be exploited at rate higher than their regeneration levels. Nonrenewable resources should not be depleted at rates higher than the development rate of renewable substitutes. The absorption and regeneration capacity of the natural environment should not be exceeded. Sustainability
- 7. Cradle to cradle design Use of nature as a model for ending the cradle to grave cycle of manufactured products. In cradle to cradle design, wasted materials are basically nutrients for another products.
- 8. Cradle to Cradle DESIGN
- 9. Source Reduction Energy saving Saves money Benefits of reducing & reusing Reduces greenhouse emissions Helps to sustain environment Reduces the amount of waste to be recycled Increases efficiency of products Limiting the need to harvest raw materials
- 10. Source Reduction
- 11. Green Innovation “Innovation that consist of new or modified processes, practices, systems and products which benefits environment and contribute to environment sustainability.” By Energy Saving Pollution Prevention Waste Recycling Green Products Design Corporate Environmental Management
- 12. Green Innovation
- 13. Types of Green Technology Green Energy Green Building Green Purchasing Green Nanotechnology
- 14. Green Energy Energy comes from natural sources such as sunlight, wind, rain, plants, algae and geothermal heat. These sources are renewable. Have a much smaller impact on environment. It can change fossil fuels in all major areas of use including electricity, water and space heating and fuel for motor vehicles.
- 15. Green Energy Solar and Wind Energy Hydral Energy
- 16. Green Building “A building that, in its design, construction or operation eliminates negative impacts and can create positive impacts on natural environment and has features like:” Good indoor environmental air quality. use of renewable resources. Pollution and waste reduction measures.
- 17. Green Building Use of non-toxic materials. Consideration of environment in design, construction, and operation. A design that enables the adaptation to changing environment. efficient use of resources.
- 18. Green Building Menara Worldwide G Tower Kuala Lumpur
- 19. Green Purchasing It involves choosing the products and services that are safe for human body, society and for environment. Instead of that products and services which serve the same purposes. Having traditional parameters of price, quality, and functionality.
- 20. Green Purchasing
- 21. Green Nanotechnology use of nanotechnology products and manufacturing process in order minimize human health and potential environmental risks heightening the environmental sustainability.
- 22. Production of materials and products for nanotechnology considers four things: 1. No use of toxic ingredients 2. At very low temperature using less energy 3. Renewable inputs wherever possible 4. Using life cycle thinking all design and engineering stages
- 25. Power of Positive Green Thinking Inventors should know that green inventions and clean technologies are good for business. The are the fast growing markets with growing profits. Consumers should know that buying green inventions can reduce energy bills and are often safer and healthier than non-green technologies. Even making small changes can have a large- term impact, for example, changing out reusable water bottles for disposable ones is health-promoting, eco-friendly.
- 26. Benefits of Green Technology Recycling Purifying of water Purifying the air Conserving energy Waste to energy Environmental remediation Rejuvenating ecosystems Benefits to rural and urban areas
- 27. Examples of Green Technology Solar Array Reusable Water Bottles Wind Generator Solar Water Heater Rainwater Harvesting System Insulations of Houses Vertical Gardens and Farms Natural Gas Boilers Vehicles that do not emit gases
Editor's Notes
- #5: Group of methods and materials, techniques and system to conserve the natural environment and resoureces,which minimizes and reduces the negative impacts of human activities
- #7: In other words meeting present needs without compromising the ability of future generation to meet their own needs
- #8: By creating that products that can be fully re-claimed or re-used Products and systems are designed to reabsorb obsolete materials back into the system and then re-use them, e;g water cycle
- #10: Reducing waste and pollution by changing the patterns of production and consumption or reusing It includes purchasing durable, long-lasting goods and seeking products and packaging that are free of toxic as possible
- #17: 1: Like water, energy ……4: and enabling of re-use and recycling 3: Like solar energy
