This document discusses hazardous waste management. It defines hazardous waste and lists its sources such as petroleum refineries and metal industries. It classifies hazardous wastes based on their ignitability, corrosivity, reactivity and toxicity. It outlines the rules and regulations for generators and transporters of hazardous waste. The key strategies discussed for hazardous waste management are waste minimization through reduction, recycling and exchange, treatment through physical, chemical and biological methods, incineration, solidification, and disposal in landfills.
this presentation defines the types of hazardous waste and the effects that it has on human and the environment or the public health as a whole and how to manage it.

Toxic waste is waste material that can cause death, injury or birth defects to living creatures. It spreads quite easily and can contaminate lakes, rivers, and the atmosphere. The term is often used interchangeably with “hazardous waste”, or discarded material that can pose a long-term risk to health or environment.

Synthetic Fiber Construction in lab .pptxPavel ( NSTU)
Synthetic fiber production is a fascinating and complex field that blends chemistry, engineering, and environmental science. By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.

A Strategic Approach: GenAI in EducationPeter 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.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
2. HAZARDOUS WASTE MANAGEMENT
DEFINITION: Any residues or combination of
residues otherthan radioactive waste which by
reason of its chemical reactivity or toxic,
explosive, corrosive or other characteristics
causes potential hazard to human or
environment, either alone or when in contact
with other wastes and which therefore cannot
be handled, store, transported, treated or
disposed off without special precautions.
3. SOURCES:
• Inorganic &organic chemicals
• Petroleum refineries
• Iron & steel
• Non ferrous metals
• Leather tanning
• Metal finishing.
5. RULES & REGULATIONS OF HW:
Aim at providing control
Specify the responsibilities
Regulations governing generators of HW
1.preparation for transport
2.manifest requirements
3.record keeping & reporting
Regulations governing transporters of HW
1.notification prior to transport
2.manifest requirements
6. TRANSPORTATION & STORAGE OF HW:
The CRADLE TO GRAVE concept
HW generated at source requires movement
by trucks to further.
Requires serious care & attention while
moving
HW to be properly packed & labelled for
transport to ensure safe handling
Storage facilities are used to store waste
temporarily before treatment & disposal.
7. HAZARDOUS WASTE MANAGEMENT STRATEGY:
OBJECTIVES:
1. Waste minimization
2. Detoxification & neutralization of waste by
treatments
3. Destruction of combustible waste by
incineration
4. Solidification of sludge & ash from steps from 2
&3
5. Disposal of residues in landfills.
10. Physical treatment :
• Involves variety of seperation techniques
• Whenever a waste containing liquid & solid
must be treated.
• Physical processes are
• Screening, sedimentation, centrifugation,
flotation, adsorption, stripping and RO.
11. Chemical treatment:
To make the complete breakdown of HW into
non toxic form and
To reduce the hazard of a particular waste
Chemical methods are ::
Neutralization, precipitation, oxidation and
reduction.
12. • Neutralization: carried out when the waste
contains excessive amount of acid or alkali.
• Chemical oxidation:used to destroy toxic
cyanide molecule with oxidising agents
• Reduction: used in the conversion of hexa
valent chromium into trivalent chromium
before it can be precipitated.
• Anodic electrolysis: used for the destruction
of cyanide in spent stripping & plating
solutions.
13. Biological treatment:
Differnet types of microorganisms are used for
degradation of specific compounds of HW
Some microbes found in soil & sewage sludge
have been tested in the degradation of organic
chemicals
Tests have been conducted to degrade PCBs using
pseudomonas & flavo bacterium.
Psuedomonas bacteria – benzene, phenol ,cresol.
14. 3. INCINERATION:
able to achieve 99.99% destruction & removal
efficiency of hazardous components in waste.
Primary products are CO2, vapour & ash
Sulphur bearing wastes gives off SO2, CO2,
H2O when incinerated.
By products of incomplete combustion are
sometimes more harmful.
Two types of incinerators: liquid injection
system, rotary kilns.
15. 4.Solidification or Stabilization:
Convert the waste into an insoluble,rock hard
material.
Additive materials used to reduce the mobility
of pollutants in the waste.
Certain materials like nickel cannot be
destroyed or detoxified by above methods.
The residues that are left out are solidified to
reduce the leachability.
16.
17. 5.DISPOSAL METHODS:
The options for disposal include land disposal,
underground disposal & deep well injection.
The choice of disposal method should be
based on evaluation of economics & potential
pollution risks.
To prevent environmental pollution from
landfills , it is essential that site c/s are taken
into account.
