Green technologies primarily affect biodiversity by reducing emissions and other environmentally harmful outputs that contribute to climate change and habitat pollution. The main green technologies that are discussed on this page have clean energy, green transportation, and efficiency applications. The replacement of old technologies should be done with newer versions that reduce emissions by eliminating fossil fuels or increasing efficiency. Replacing current, dirty technologies with green versions is the only way to preserve the many species that are highly susceptible to climatic and environmental changes caused by humans. Replacing old technologies worldwide would be a very expensive project, so we propose replacing dirty technologies when they become obsolete with the cleanest options that are available at that time.

Polymer in the real life - Devoxx France - 2016 04-20Horacio Gonzalez
In the last two years I've been speaking a lot about web components and Polymer in conferences and user-groups, sharing a vision of the upcoming web-component revolution. But after these introductory talks I often got the same question: "that seems great... but does it works in Real Life?" Ah, the pesky real life question...
In this talk I'm going to tackle that question in the best way I know: I'm going to tell you my experience of almost two full years web applications with Polymer in the real life, for real projects in a real enterprise with real costumers, and all the lessons I've learnt from it.
You will heard why did I choose Polymer, how I dealt with the 0.x versions lifecycle, the good points and the bad ones too, how I did integrate lots of 3rd part libs into a component architecture and how now I'm able to create full fledge Progressive Web Apps using Polymer in a simple way without having to deal with the complexity of Angular/React/Whatever JS, but also how to integrate your components into those frameworks if needed.
Polymer clay is a sculptable material based on the polymer polyvinyl chloride (PVC). It usually contains no clay minerals, and is only called "clay" because its texture and working properties resemble those of mineral clay. It is sold in craft, hobby, and art stores, and is used by artists, hobbyists, and children.

Conclusion
Green chemistry is the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products.
Aldehydes and ketones contain the carbonyl group. Aldehydes are considered the most important functional group. Ketones A carbon double bonded to an oxygen is called a carbonyl group. Compounds in which the carbon of a carbonyl group is bonded to two other carbons
Chemistry is the branch of science concerned with the substances of which matter is composed, the investigation of their properties and reactions, and the use of such reactions to form new substances
The NO2 group attached with organic chain is called as nitro functional group. All the compounds containing the nitro functional group are called as organic nitro compounds.
In Earth science, a biogeochemical cycle or substance turnover or cycling of substances is a pathway by which a chemical substance moves through both the biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) components of Earth.
Natural resource economics focuses on the supply, demand, and allocation of the Earth's natural resources to create a more efficient economy.The main objective of natural resource economics is to gain a better understanding of the role of natural resources in the economy.
Air pollution occurs when harmful substances including particulates and biological molecules are introduced into Earth's atmosphere. It may cause diseases, allergies or death in humans; it may also cause harm to other living organisms such as animals and food crops, and may damage the natural or built environment. Human activity and natural processes can both generate air pollution.
A mineral resource is the concentration of materials that are of economic interest in or on the crust of the Earth. Almost all minerals found on Earth are used in one way or another for economic benefit. Examples of minerals include gold, gravel, sand, aluminum, copper, limestone, clay and diamond.
Environmental Impact Assessment (EIA) is the process by which the anticipated effects on the environment of a proposed development or project are measured. If the likely effects are unacceptable, design measures or other relevant mitigation measures can be taken to reduce or avoid those effects.
Vanishing creams – which can also be called stearate creams – were known for their smooth, dry feel on the skin and their pearly sheen. Chemically they are oil-in-water emulsions consisting of stearic acid, an alkali, a polyol and water.
Cosmetic products which have a quick turnover, and relatively low cost are known as Fast Moving Consumer Goods (FMCG). Indiaʹs FMCG sector is the fourth largest sector in the economy.
In this lecture we will discuss about the preparation of some skin care products :Creams (cold, vanishing and shaving creams), Sun-tan lotions, Face powder, Lipsticks, Talcum powder, Nail enamel,
Natural resource management is a discipline in the management of natural resources such as land, water, soil, plants and animals, with a particular focus on how management affects the quality of life for both present and future generations. Soil is defined as the unconsolidated portion of the earth's crust modified through physical, chemical, and biotic processes into a medium capable of supporting plant growth. Soil properties influence the natural and the physical infrastructure of the landscape and ecosystems.
A "cosmetic product" is any substance or mixture intended to be placed in contact with the various external parts of the human body (epidermis, hair system, nails, lips and external genital organs) or with the teeth and the mucous membranes of the oral cavity with a view exclusively or mainly to cleaning them, perfuming them, changing their appearance and/or correcting body odours and/or protecting them or keeping them in good condition.
The Purpose of cosmetics is intended to :
clean
perfume
change appearance
correct body odour
protect
keep in good condition
Natural Resources are all that exists without the actions of humankind. This includes all natural characteristics such as magnetic, gravitational, and electrical properties and forces. On earth we include sunlight, atmosphere, water, land (includes all minerals) along with all vegetation and animal life that naturally subsists upon or within the heretofore identified characteristics and substances.
The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only species we consider rare, threatened, or endangered, but every living thing—even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems.
The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed.
An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.
Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

13. What is Green technology Or
Environmental technology or
Clean technology?
Green Technology or Environmental technology
or Clean technology is the application of one or more
of environmental Sciences, Green chemistry,
environmental monitoring and electronic devices to
monitor, model and conserve the natural environment
and resources, and to curb the negative impacts of
human involvement.
Green technology is a field of new, innovative ways to
make changes in daily life. Currently, this Clean
Technology is in the beginning stages of its
development, so the future will only bring bigger and
better things for this field.
14. Green Technology is part of Business
Exchange ( from developed countries to
developing or reverse order).
Cleantech, is new technology and
related business models offering
competitive returns for investors and
customers while providing solutions to
global challenges
Green Technology is the safeguard
against environmental pollution.
Green Technology gives the concept of
cleanliness and freshness.
15. What is Green chemistry?
The invention, design and application of
chemical products and processes to
reduce or to eliminate the use and
generation of hazardous substances.
16. Adopting the green technology, we are
intending to make the earth green free from any
danger.
Our environment needs salvage from
pollution. With the help of recycling process we
can reduce the waste material. Reusable things
are better to introduce to improve the
cleanliness level.
Water is the basic for green life which is the
symbol of cleanliness. Impure water causes
many diseases.
Water is the basic ingredient of Green
Technology without water there is nothing
fresh.
17. Planting more and more trees is the
demand of present environment. They
absorb carbon dioxide from surrounding
and release oxygen which helps us to
breath(United Nations has declared the year 2011 as the
‘International Year of Forests’).
Developing proper sewage system needs
innovative green technologies.
This waste water should be directed
towards the places where it can be used
like fields.

19. Recycling: eg. Liquid and solid waste recycling
Water purification: The whole idea/concept of having
dirt/germ/pollution free water flowing throughout the environment.
Air Purification: basic and common green plants can be grown
indoors to keep air fresh because all plants remove CO2 and
convert it into oxygen.
Sewage treatment is conceptually similar to water purification.
Environmental remediation is the removal of pollutants or
contaminants for the general protection of the environment.
Solid waste management is the purification, consumption, reuse,
disposal and treatment of solid waste
Renewable energy is energy that can be replenished and that can
be produced by natural resources/minerals like wood, sun,
wind,tides, water etc.
E-gain forecasting is a method using forecasting technology to
predict the future weather's impact.
Energy conservation is the utilization of devices that require smaller
amounts of energy in order to reduce the consumption of electricity
( Carbon Credit programme- eg. CFL lamp distribution in Kerala).
20. Recycling
Recycling is processing used materials (waste) into
new products to prevent waste of potentially useful
materials, reduce the consumption of fresh raw
materials, reduce energy usage, reduce air pollution
(from incineration) and water pollution (from landfilling)
by reducing the need for "conventional" waste disposal,
and lower greenhouse gas emissions.
Recycling is a key component of modern waste
reduction and is the third component of the "Reduce,
Reuse, Recycle" waste hierarchy.

44. Incineration
Incineration is a disposal method in which solid organic
wastes are subjected to combustion so as to convert
them into residue and gaseous products. This method is
useful for disposal of residue of both solid waste
management and solid residue from waste water
management.This process reduces the volumes of solid
waste to 20 to 30 percent of the original volume.
Incineration and other high temperature waste
treatment systems are sometimes described as "thermal
treatment".
Waste-to-energy (WtE) or energy-from-waste
(EfW) is the process of creating energy in the form of
electricity or heat from the incineration of waste source.
Incineration, the combustion of organic material such as
waste with energy recovery is the most common WtE
implementation.
45. Landfill
Disposing of waste in a landfill involves
burying the waste, and this remains a
common practice in most countries.
Landfills were often established in
abandoned or unused quarries, mining
voids or borrow pits. A properly designed
and well-managed landfill can be a
hygienic and relatively inexpensive
method of disposing of waste materials.
