Pollution due to plastic waste
Plastic pollution has become a major environmental issue globally and in India. Large quantities of various types of plastic waste are generated each year from numerous sources. This plastic waste pollutes water bodies, soil, and oceans. When plastic debris is ingested by marine life and wildlife, it can cause injury or death. Plastic pollution also threatens soil quality and has negative impacts on human health through chemicals leached from plastic. Effective control measures are needed from governments, organizations, and individuals to properly manage and reduce plastic waste.
Plastics
Plastic poses significant environmental problems. It is made from polymers that do not degrade and can persist in the environment for centuries. When plastic litter ends up in oceans and waterways, it kills over 100,000 marine animals every year either through ingestion or entanglement. Plastic bag litter also pollutes landscapes worldwide. While recycling aims to reduce plastic waste, the recycling process itself can release toxic fumes and harm workers. Small actions like using reusable tote bags and reducing single-use plastic can help address this global issue. Government regulations and individual responsibility are both important to lessen the environmental impact of plastics.

Plastics Disadvantages & Recycling
Plastic bottles have several disadvantages, including that they take an extremely long time (500 years) to decompose in landfills. Additionally, plastic is difficult to recycle effectively as most plastic cannot be recycled and recycled plastic is often downcycled into lower quality products. A further disadvantage is that plastic production relies on non-renewable resources like oil and natural gas. Large quantities of discarded plastic end up polluting the environment and harming wildlife through ingestion and entanglement.
Plastic pollution
Plastic pollution is when plastic has gathered in an area and has begun to negatively impact the natural environment and create problems for plants, wildlife, and even the human population.
In total, half of all plastic produced is designed to be used only once — and then thrown away. Plastic waste is now so ubiquitous in the natural environment that scientists have even suggested it could serve as a geological indicator of the Anthropocene era.

Recycling plastic saves energy and resources compared to producing new plastic from raw materials. The document concludes that recycling is important to reduce environmental impacts and plastic waste in landfills.
Plastic 1
Plastic is a general term for synthetic polymers that can be molded into solid objects. The first plastic, Parkesine, was created in 1862 from cellulose. Plastics are made from polymers formed through addition, condensation, or addition polymerization reactions from raw materials like monomers, plasticizers, and fillers. The two main types are thermoplastics, which soften when heated and harden when cooled, and thermoset plastics, which harden permanently after heating. Common plastics include polyethylene, PVC, PVA, and bakelite. Plastics are used widely due to properties like light weight, corrosion resistance, strength, and insulation.
Plastic and Environment
Plastic is all around us. It forms much of the packaging for our food and drink. For many of us, it is throughout our home, our workplace, our car, the bus we take to and from work. It can be in our clothing, eyeglasses, teeth, toothbrush, computers, phones, dishes, utensils, toys. The list goes on, especially when you look around and begin to notice the plastic in your life.
Plastic is versatile, lightweight, flexible, moisture resistant, durable, strong and relatively inexpensive. It can be chemical resistant, clear or opaque, and practically unbreakable. These are wonderful useful qualities, and plastic plays many important roles in life on Earth, but the widespread use of plastic is also causing unprecedented environmental problems, and harbours serious health risks . Plastic should be used wisely, with caution and only when suitable alternatives do not exist or are not available.
Plastic Recycling
This document outlines a business plan for a plastics recycling business. It will require an initial investment of up to 8 million rupees excluding land costs, and will need at least 1 acre of land.

The use of bioplastics is growing due to concerns about climate change and waste reduction. The document outlines the bioplastics production process, applications in various industries, and disposal methods after use.
Lecture+10+Waste
1. The document discusses waste management and sustainability strategies to address pollution from waste. It covers topics like waste classification, sources of waste, effects of waste pollution, and international agreements to control hazardous waste.
2. Sustainable waste management strategies include reducing waste production, reusing materials, recycling, and proper disposal methods like sanitary landfills and incineration. Industries can help prevent pollution by improving efficiency, finding new uses for waste, and designing products for recyclability.
3. Major international agreements discussed are the Basel Convention on hazardous waste trade and the Stockholm Convention on persistent organic pollutants. Both aim to protect human health and the environment from the adverse effects of hazardous materials.
Plastic waste and management
Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans.[1] Plastics that act as pollutants are categorized into micro-, meso-, or macrodebris, based on size.[2] The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans.[3] However, it is slow to degrade.[4] Plastic pollution can unfavorably affect lands, waterways and oceans. Living organisms, particularly marine animals, can also be affected through entanglement, direct ingestion of plastic waste, or through exposure to chemicals within plastics that cause interruptions in biological functions. Humans are also affected by plastic pollution, such as through the disruption of the thyroid hormone axis or hormone levels. In the UK alone, more than 5 million tonnes of plastic are consumed each year, of which an estimated mere 24% makes it into recycling systems. That leaves a remaining 3.8 million tonnes of waste, destined for landfills.[5][6] Plastic reduction efforts have occurred in some areas in attempts to reduce plastic consumption and pollution and promote plastic recycling.
Intro to green chemistry
This document discusses environmental disasters and regulations enacted in response. It provides examples of well-publicized pollution incidents like the Cuyahoga River catching fire and the Bhopal disaster. These incidents helped rally support for environmental laws like the Clean Water Act and Superfund. The document also discusses the growth of environmental regulation over time in response to crises. It introduces the concepts of pollution prevention and green chemistry which aim to reduce hazardous materials and waste from the start.
Plastic free Ahmedabad - CSR Activity
An initiative taken by School for awareness of uses Pros and Cons Plastic. Which include Awareness Rally, Cleanliness Drive and Street Plays.
Plastic recycling
The document discusses plastic pollution and recycling. It notes that plastic production has greatly increased globally but plastic is very slow to decompose, with some plastics taking over 1000 years. This causes plastic pollution in oceans, where it kills and endangers wildlife through entanglement and ingestion. The document advocates for more sustainable plastic recycling approaches to address this growing environmental problem.
Microplastics
Microplastic - Primary and Secondary microplastics - Sources - Environmental and health impact - Solutions.
2016 08-08 ecology and environment
This document discusses different types of pollution in the natural environment, focusing on air pollution. It defines air pollution as the presence of substances in the atmosphere that exceed natural levels and negatively impact living beings. Air pollutants come from natural sources like volcanoes and fires, as well as man-made sources such as factories, power plants, and automobiles. The document also outlines different approaches to reducing pollution, comparing cleaner production which prevents pollution at the source through efficient material use, to end-of-pipe treatment which focuses on treating existing waste and emissions.
green products
Industrial hazards arise from mass production and can occur at any stage, from extraction to disposal. They generally involve releasing damaging substances or energy from facilities into the environment. While malfunctions cause some hazards, the risks also depend on complex interactions between industrial systems, human factors, and the environment. Key areas of risk include manufacturing, material handling and storage, transportation, and damage can be done to the environment, infrastructure, health, and local economies.
Pyrolysis process 11035
R1. The document discusses using waste plastic to produce fuel through pyrolysis. It notes that plastic waste represents a considerable portion of municipal waste.
R2. It reviews literature on treating plastic waste through various processes like primary treatment, secondary treatment, tertiary treatment and quaternary treatment. It states that tertiary/chemical treatment can produce chemicals and fuel mixtures.
R3. The proposed methodology is to commercialize the pyrolysis process using an upgraded plastic waste collection system and optimized parameters to produce high quality, sulfur-free fuel at low operating costs.
Introduction to Green Chemistry
Green chemistry aims to reduce the use and generation of hazardous substances in chemical processes. It was initiated in the US after the 1990 Pollution Prevention Act and focuses on preventing pollution by devising greener synthesis and replacing toxic solvents. The document provides examples of environmental problems caused by chemicals like pesticides and CFCs and the need to develop safer and more sustainable alternatives through green chemistry approaches.
BioEnzyme Technologies Presentation
BioEnzyme Technologies has developed a unique enzyme-bacteria based chain-end biodegradation technology to produce biodegradable plastic products. Their formulation uses organic ingredients from natural resources and plants to make the process non-hazardous. Products produced with this technology, including garbage bags, fully biodegrade within 180 days according to EN 13432 standards. This overcomes limitations of plant-based bioplastics which are expensive, show poor performance, and require industrial composting facilities to biodegrade. BioEnzyme has successfully marketed their BIOPLAST branded bags with a major retailer in Turkey through a pilot program.
The Contribution of Businesses to the Environmental Pollution
Nowadays, the impact of businesses on the environment has become and still remains a critical part of its
overall performance. A business might be doing a great job in providing people with superior and reliable
products, services and jobs, but on the other hand, its activities may be enormously contributing to the
environmental pollution.

Tsunami
A tsunami is a series of massive sea waves caused by underwater earthquakes, landslides, or volcanic eruptions. Tsunamis can travel across entire oceans at speeds up to 800 km/h but remain unnoticed at sea due to their small height. However, when they reach shallow coastal waters, the top of the wave moves faster than the bottom, causing the sea to rise dramatically to heights over 30 meters. The most devastating tsunami on record was on December 26, 2004 when a massive earthquake off the coast of Sumatra, Indonesia triggered a tsunami that caused widespread destruction across the Indian Ocean region.
Project tiger
Project Tiger was initiated in 1973 to protect tigers and their habitats in India. It aims to maintain viable tiger populations across different bio-geographic regions by establishing tiger reserves. The project helped increase India's wild tiger numbers from 1,200 in the 1970s to 3,500 in the 1990s, though a 2008 census found the population had declined to 1,411. Project Tiger is administered through the National Tiger Conservation Authority and involves coordinated efforts between field directors, central directors, and other agencies to protect tiger habitats and populations through monitoring, anti-poaching efforts, management planning, and addressing community needs.

Number 3 is V.S. Naipaul, who won the Nobel Prize in Literature and other awards but also attracted controversy for his remarks about women writers.
Diminishing of rain forests
Forests provide economic, environmental, social and cultural benefits but are threatened by deforestation and degradation caused primarily by human activities like excessive harvesting. Deforestation contributes to issues like climate change, biodiversity loss and food insecurity by reducing natural resources that humans depend on. Innovative solutions and leadership are needed to ensure forests continue providing benefits for future generations.
Cricket
Cricket is a bat-and-ball game played between two teams of 11 players on a field. One team bats while the other bowls and fields, with the objective of scoring more runs. Cricket originated in southern England in the 16th century and became England's national sport in the 18th century. There are different formats of cricket including Test matches that can last up to 5 days and One Day Internationals with each team getting one innings of a limited number of overs. A cricket team consists of specialist batsmen, bowlers and an all-rounder who excels at both batting and bowling under the leadership of a captain.

Adventure sports in india
This document discusses adventurous sports in India, including river rafting and mountaineering. It describes different types of river rafting such as oar rafting and paddle rafting. Mountaineering is defined as a sport that combines climbing and hiking up mountains on regular terrain, rocky areas, and ice or snow slopes using tools such as ropes, harnesses and ice axes. Some benefits of these sports include calorie burning, heart health and personal growth, while risks include weather dangers, impact on nature, and risk of life. Several mountains in India that are popular for mountaineering are also listed.
Global warming
Global warming is a gradual increase in the Earth's temperatures caused by greenhouse gases like carbon dioxide trapping heat in the atmosphere. The greenhouse effect makes the Earth warm enough for life, but excess pollution is exacerbating global warming and harming the environment. Effects of global warming include rising sea levels which flood islands and damage habitats, killing ocean algae and reducing food sources, and more frequent wildfires caused by hotter temperatures. Reducing carbon emissions through measures like carpooling and conserving energy can help limit global warming and protect the environment long-term.

The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
