What is E-waste? – What causes E-waste?: Rapid development of upgraded electronic equipments forces the disposal of outdated equipments. – What makes E-waste hazardous?: All electronic equipments are made up of materials, which are harmful to human and pollute the environment when exposed. The harmful materials used in the manufacture of electronic equipments are Lead, Mercury, Plastics, CFCs, Cadmium, etc. – Current status of E-waste: E-waste now a day’s forces the world experts to turn back, as it’s a rapid growing problem in the developed and developing countries to recycle it or to dispose it safely so that they don’t pose any environmental pollution or hazards. – What caused the current state of E-waste: The lack of awareness about the hazardous & polluting nature of E-waste. And the cost to recycle E-wastes. – How to control E-waste? Reduce and Recycle: When a equipment is not working it doesn’t mean that the whole equipment has spoiled but generally just one part. By trying to use the equipments as long as possible by getting it repaired at service centers helps in reducing the accumulation of E-wastes. On the other hand certain equipments have to be disposed, at that time recycling of them prevents E-waste. – How to recycle?: The recycling of E-waste is not a simple process that can be performed all were, as they deal with harmful materials, and which requires lot of stuffs. The recycle of E-waste is done in many categories according to the material out of which it is made. – Benefits of recycling E-waste: The electronic equipments are made of material or resources such as Lead, Mercury, Plastics, CFCs, Cadmium, etc., which are nonrenewable can be recovered by the recycling process. Thus preventing nonrenewable resources from becoming extinct. Due to the availability of resources by recycling too they may account for the decrease in cost of the equipments. – Why recycling of E-waste is costly: The recycling of E-waste is costly when compared to recycling of other matters. This is because the composition of the equipments are harmful the recycling of which should be done with extensive care in hi-tech manner with expensive tools. The recycling of E-waste requires large labor as the primary aspect of recycling them is to categories them in metals, plastic, glass, etc., for further processing. As major constituent of E-waste is circuit board the de-soldering of which requires labor? These things makes recycling of E-waste costly. – Steps to control E-waste: The major reason of E-waste is the lack of awareness about it among the consumers of the electronic equipments. The control of E-waste can be achieved by creating awareness to the consumers about the hazardous nature of the equipments on disposal while selling the products. The E-waste recycle centers should be in reach of the consumers to disclose them safely to the recycler. The produce of the electronic equipments can implement the E-waste recycle unit

It contains toxic heavy metals like lead, mercury, cadmium which can harm human health and the environment if e-waste is not disposed of properly. While landfilling and incineration are common disposal methods, recycling and reuse of e-waste is recommended to recover valuable materials and reduce environmental pollution.
This document discusses electronic waste (e-waste) and its impact. It defines e-waste as discarded electronic items like computers and phones. E-waste is dangerous if improperly disposed of, as components can leach toxic chemicals into soil and water. The document outlines how e-waste affects life through land and air pollution and health issues. It provides statistics on India's large and growing e-waste volumes. It also describes e-waste management approaches like recycling and calls for responsible actions from governments, industries, and citizens to properly handle e-waste.

E-waste is a rapidly growing problem around the world. Improper disposal of old electronics releases harmful toxins into the environment. Recycling electronics through certified recycling centers is an important solution, as it allows for electronics to be broken down using eco-friendly processes and machinery. Recycling centers collect, transport, sort, dismantle electronics and ensure waste is safely disposed of. Individuals and companies can donate or sell old electronics to recycling centers to help reduce the environmental impact of e-waste.
Electronic waste is a growing problem as new electronics are constantly being released and older versions become obsolete. This excess waste ends up in landfills and recycling centers, or is even shipped overseas where it is broken down under dangerous conditions. The document proposes several ways to limit electronic waste, such as reusing and donating old devices, companies offering recycling incentives, informing the public about local recycling options, and making devices easier to repair by replacing individual parts. Overall, increasing awareness of electronic waste issues and providing more sustainable recycling programs could help address this significant environmental challenge.
The document discusses e-waste management issues in Kerala, India. It notes that e-waste generation is increasing globally by 5-10% annually due to rapid changes in technology and affordability of devices. Only 5% of e-waste is recovered. E-waste contains hazardous materials like lead, mercury, and chemicals that can damage health if improperly disposed. In India, 90% of e-waste is handled by the unauthorized sector and most ends up in landfills or being improperly recycled. The Kerala government has partnered with a company to collect e-waste from across the state to scientifically recycle it. Stricter regulations and a national organization are needed to properly manage India's large e-waste volumes.

E-waste is the fastest growing waste stream in the world due to rapid technological advances and planned obsolescence. In India, approximately 1.7 million tons of e-waste was generated in 2014, making it one of the largest generators of e-waste globally. However, only 3% of e-waste in India is properly recycled due to the presence of toxic metals like lead, mercury, and cadmium which can cause damage to human health and the environment if not handled correctly. Initiatives like the CLEAN e-INDIA program aim to establish responsible e-waste collection and recycling practices to help make India e-waste free.
- E-waste is electronic equipment that is nearing the end of its useful life. It contains hazardous materials like lead, cadmium, and mercury.
- Improper disposal of e-waste can pollute soil and water sources with toxic chemicals. Workers involved in the recycling process are also at high risk of health issues if safety procedures are not followed.
- E-waste management involves collection, sorting, transportation to recycling facilities where valuable materials are recovered through dismantling and smelting processes. The remaining waste is either disposed of safely or exported for further metal recovery.

Trichogramma spp. is an efficient egg parasitoids that potentially assist to manage the insect-pests from the field condition by parasiting the host eggs. To mass culture this egg parasitoids effectively, we need to culture another stored grain pest- Rice Meal Moth (Corcyra Cephalonica). After rearing this pest, the eggs of Corcyra will carry the potential Trichogramma spp., which is an Hymenopteran Wasp. The detailed Methodologies of rearing both Corcyra Cephalonica and Trichogramma spp. have described on this ppt.
Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.
2. Hey Smarty!
Where are you going
with that box ?
What’s in it?
I am going to an
E-Waste drive. This
box contains used
electronic goods I
want to donate.
3. What is E-Waste?
And why are you carrying
this heavy box to a drive
when you can dump it in a
garbage bin?
It is waste after all!
E-Waste is old, broken or
discarded electronic appliances
that are towards the end of it’s
life. Remember! We cannot dump
E-Waste in dustbins as it is a lot
more harmful than regular
waste.
The best way to limit it’s
harmful effects is to recycle
E-Waste.

The 3 R’s Rule For E-Waste
Reduce – First step of the “3 R’s” Rule - reduce
consumption, which in turn minimizes the volume of
what will eventually become waste.
Reuse – Second step of the “3 R’s” Rule - reuse
materials for as long as is practical. Reuse extends
the lifespan of these materials and greatly "Reduces"
consumption of new manufactured goods.
Recycling - Last step of the “3 R’s” Rule comes in
the picture when an item’s reuse in its original
intended purpose is no longer an option.
The goods are processed and transformed
into new electronic goods.
