Biorestoration deals with restoring or bringing back to an original or near original state using living micro-organisms. Nature has a built in check and balance system in everything it does. If there is too much or too little of something nature will use various life forms to try to re-establish a balance

• Bioremediation – process of cleaning up environmental sites contaminated with chemical pollutants by using living organisms to degrade hazardous materials into less toxic substances
Bioremediation is the use of microorganisms (e.g., bacteria, fungi), plants (termed phytoremediation), or biological enzymes to achieve treatment of hazardous waste. Treatment can target a variety of media (wastewater, groundwater, soil/sludge, gas) with several possible objectives (e.g., mineralization of organic compounds, immobilzation of contaminants). In situ bioremediation (ISB) is the application of bioremediation in the subsurface – as compared to ex situ bioremediation, which applies to media readily accessible aboveground (e.g., in treatment cells/soil piles or bioreactors). In situ bioremediation may be applied in the unsaturated/vadoze zone (e.g., bioventing) or in saturated soils and groundwater (Sharma S. 2012).

ABSTRACT
The term bioremediation has been introduced to describe the process of using biological
agents to remove toxic waste from environment. Bioremediation is the most effective management tool to manage the polluted water and recover contaminated waste water. It is an attractive and successful cleaning technique for polluted environment; it has been used at a number of sites worldwide, with varying degrees of success.
•Introduction of bioremediation: Bioremediation refers to the process of using microorganisms to remove the environmental pollutants i.e. toxic wastes found in soil, water, air etc.
•In situ bioremediation:
It involves a direct approach for the microbial
degradation of xenobiotics at the sites of pollution
(soil, ground water).
•Types of in situ bioremediation:
Natural attenuation.
Engineered in situ bioremediation.
- Bioventing, biosparging, bioslurping,
phytoremediation.
•Ex situ bioremediation:
Waste or toxic pollutants can be collected from the polluted sites and bioremediation can be carried out at a designated place or site.
• Types of ex situ bioremediation
Land farming, windrow, biopiles, bioreactors.
•Microorganisms use in bioremediation:
A number of naturally occurring marine microbes
such as Pseudomonas sp. is capable of degrading oil and other hydrocarbons.
•Factors affecting bioremediation:
Nutrient availability, moisture content, pH, temperature, contaminant availability.

Bioremediation is the process in which the micro-organisms are used to degrade the pollutants from the environment. Plants and micro-organisms are used to clean up the environment. Bioremediation is carried out by microbes and their metabolisms are used to remove the contaminants. Microbes have the ability to resolve the issue of contaminated ecosystem1. To improve or better living style the degradation of contaminated areas is very important. Importance of the biodegradation is increasing due to the expensiveness of the chemicals. So bioremediation is the best choice. The effluents should be degraded from the environment because they are very dangerous and have a bad impact on human beings. These pollutants sink into the water and cause pollution. These pollutants are treated with the help of microbes in bioremediation process. It is the best method because it is cost effective and eco-friendly. Different techniques of bioremediation are used to convert toxic substances into less toxic substances.

What is The Meaning Of Biodegradation?
A biodegradable product can dissolve easily in the environment without destroying nature. It’s the opposite of plastic and Styrofoam, which harm the environment.
The meaning of biodegradation is breaking down of organic substances by the help of other living organisms such as bacteria and microbes.
History:
The first known use of the word in biological text was in 1961 when employed to describe the breakdown of material into the base components of carbon, hydrogen, and oxygen by microorganisms .

A Review on Applicability of Photocatalyst Titanium dioxide for Treatment of ...IJERA Editor
Greywater reuse has attracted great attention for sustainable management of water especially under water
scarcity conditions. However, the effort has been limited by the presence of toxic organics in the effluent which
in turn inhibits the public acceptance of recycling water. The existence of those organic pollutants, which cannot
be eliminated by conventional primary and secondary treatment processes, can be problematic. Hence it is
necessary to explore a sustainable, robust and affordable method for treatment of greywater. Photocatalytic
oxidation is an emerging technology that could be suitable to remove refractory organic compounds found in
greywater. Recently titanium dioxide (TiO2) gained wide attention for photocatalytic oxidation of organic matter
of wastewater. Because it is biologically and chemical inert, resistant to chemical corrosion and can work at
ambient temperature and pressure, without addition of chemical species. The irradiation of titanium dioxide
dispersions by ultraviolet (UV) (300-400 nm) light can lead to the formulation of highly reactive hydroxyl
radicals which attack the pollutant molecule to degrade it into carbon dioxide, water and mineral acids.This
technology has advantages, such as, the integration into small places, low maintenance and easy operation.
The major challenge in municipal solid waste management using landfills is
leachate, which causes a significant threat to subsurface resources. Leachate is the
liquid that passes through soil and has extracted dissolved and suspended solids from
it. Municipal solid waste landfills are one of the severe environmental impacts on the
urban environment. Landfills are one of the practices of disposal of municipal solid
waste in the Indian scenario. Understanding the leachate composition is an equally
important and critical factor in terms of environmental production. When the
municipal solid waste is buried in a landfill, physical, chemical and biological
reactions occur, and the refuse reacts with the moisture present in the soil. Studying
leachate characteristics and its treatment is essential as it could threaten the
ecosystem. Rapid urbanization is one of the major contributions to the generation of
municipal solid waste. The present study reviews the different applications available
to treat the leachate generated from municipal solid waste landfills. Nano-particles
are recently gaining great interest in the protection of the environment, which will
ensure sustainable development.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
