However, the consequences of ocean pollution are becoming more and more apparent. There are many sources of ocean pollution, both point and non-point.

In this unit, we will examine organic matter and nutrients, trace metals, and organic waste. UNIT V STUDY GUIDE Ocean Pollution, Electronic Waste, Tire Recycling, and Battery Waste BEM 3601, Waste Management 2 UNIT x STUDY GUIDE Title Organic matter and nutrients can originate from natural sources, but anthropogenic contributions are significant. Excess nutrients and organic matter are a problem because they cause algae to grow excessively. When the algae dies, it decomposes due to bacteria in the water. During the process of decomposition, the bacteria use up the dissolved oxygen in the water causing dead zones where no organisms can live.

Trace metals can be dissolved or found in ocean sediments, and some come from the erosion of rocks and sediments. However, high concentrations of metal such as silver have been found in coastal regions near wastewater discharges (Macias-Zamora, 2011). Organic waste consists of oil pollution, persistent organic pollutants, and polychlorinated biphenyls. There have been over 25 major oil spills in the oceans since 1967, and oil pollution is one of the most predominant forms of ocean pollution (Macais-Zamora, 2011). Persistent organic pollutants (POPs) and polychlorinated biphenyls (PCBs) are toxic and will also bioaccumulate in ocean life.

Both classes of chemicals are persistent, so even though they are no longer being manufactured, they are still having a detrimental impact on coastal and marine ecosystems (Macais- Zamora, 2011). Electronic Waste Think about how much electronic waste you have at your home waiting for disposal. Perhaps there is an old desktop tower in the basement or maybe an old cell phone in a drawer. Electronic devices are constantly being updated, and many people buy the latest model even if the device they have is still functional. For the year 2005, it was estimated that household e-waste amounted to 20 million tons globally (Cui & Roven, 2011).

E-waste contains hazardous materials such as lead, mercury, and cadmium. Above: Workers use high-pressure, hot- water washing equipment during cleanup efforts following the Valdez oil spill. (Svdmolen, 2005) Right: Pipe runoff in the U.S. Virgin Islands runs directly into the ocean, just a short distance from reefs that may be home to numerous species of marine life. (Lfstevens, 2011) BEM 3601, Waste Management 3 UNIT x STUDY GUIDE Title As with most of the other waste streams we have learned about in this course, there is a hierarchy of how e-waste should be managed. Reuse is most preferable followed by remanufacture and recycling, then by landfilling and incineration. When e-waste is recycled, it is first dissembled to recover parts of value and to separate out more hazardous components.

This process can have detrimental impacts to human health and the environment due to the release of toxic substances during the disassembly process (Cui & Roven, 2011). Tire Recycling In 2003, 290 million scrap tires were generated in the United States. Of these, 80.4% were used as fuel or recycled. This recycling market meant that 27 million scrap tires had to be disposed of in landfills (U.S. EPA, 2014).

There are four basic material groups in all tires: natural and synthetic rubber, carbon blacks/silicas, reinforcing materials, and facilitators. Depending on the treatment level, tires can be recycled for use in a variety of ways, from asphalt additives and road sealants to play surfaces and carpet underlay (Shulman, 2011). Recycling tires can save enormous amounts of energy. According to Shulman (2011), the recycling of 8.5 million tons of tires in the European Union between 1999 and 2009, rather than manufacturing the same amount of new tire rubber, produced an energy savings of 174,300,000 barrels of petroleum. Battery Waste According to the EPA, 96% of all lead-acid batteries are recycled (U.S.

EPA, 2012). This is the largest recycling rate of any product in the United States (Miller, 2012). Since most retailers that sell batteries collect them for recycling, consumers can properly dispose of their used batteries. When batteries are not properly disposed of, they can end up in incinerators, where they release toxic chemicals into the air and incinerator ash (U.S. EPA, 2012).

Because lead is a toxic substance, it is important that we look for ways to recover even more of this waste stream. Opportunities for additional recovery would result from people being aware of, and avoiding, actions that result in the following: lead in spent batteries with consumers, mishandled batteries sent to auto wreckers, and lead in spent batteries in municipal waste (Genaidy & Sequeira, 2011).

Assignment Solution: Waste Management and Its Impacts

Introduction
Waste management encompasses the processes and actions required to handle waste from its inception to its final disposal. Effective waste management is essential for preventing pollution and its associated environmental consequences, particularly in our oceans, regarding electronic waste, and in the recycling of tires and batteries. This paper will explore the major categories of waste, the sources of coastal pollution, the effects of ocean pollutants, the environmental impacts of electronic waste, the constituents of municipal solid waste, and the methods for improving recycling rates for batteries. Furthermore, it will identify the diverse applications of recycled tires.

Major Categories of Waste

Waste is categorized based on its source, composition, and the method of disposal. Major categories encompass various types of waste:
1. Municipal Solid Waste (MSW) - This includes everyday items discarded by the general public, such as food scraps, packaging materials, and discarded consumer goods.
2. Hazardous Waste - Waste that poses substantial or potential threats to public health or the environment, including industrial waste, chemical wastes, and electronic waste.
3. Organic Waste - Biodegradable waste that comes from plant or animal sources. This includes food waste and garden debris.
4. Electronic Waste (E-waste) - Discarded electronics such as computers, televisions, and mobile devices containing hazardous components.
5. Construction and Demolition Debris - Material generated from building or demolition activities, which includes concrete, wood, metals, and other building materials (U.S. EPA, 2014).

Sources of Pollution in Coastal Environments

Pollution in coastal areas can originate from both point and non-point sources. Point sources are identifiable, such as wastewater discharges from industrial plants or sewage treatment facilities. Non-point sources are diffuse, such as runoff from agricultural land or urban areas. Key contributors to coastal pollution include:
1. Nutrient Runoff - Excess fertilizers and organic matter lead to algal blooms, which deplete oxygen in the water, creating dead zones where marine life cannot survive (Macias-Zamora, 2011).
2. Heavy Metals - Metals like lead, mercury, and cadmium can enter coastal waters through runoff, industrial discharge, or sediment erosion. They bioaccumulate in the food chain, posing risks to both wildlife and human health (Cui & Roven, 2011).
3. Oil Pollution - Major oil spills and routine discharges from ships contaminate water bodies, harming marine ecosystems and food webs (Lfstevens, 2011).
4. Plastic Debris - Increasing plastic waste from urban areas makes its way into oceans, leading to ingestion by marine animals and degradation of habitats (Macais-Zamora, 2011).

Effects of Ocean Pollutants

Ocean pollutants significantly impact marine ecosystems, biodiversity, and human health. The effects include:
1. Disruption of Marine Life - Toxic substances bioaccumulate in marine organisms, leading to reproductive and developmental issues. For example, polychlorinated biphenyls (PCBs) can disrupt hormonal systems in fish (Macias-Zamora, 2011).
2. Oxygen Depletion - Decomposing organic matter causes oxygen depletion, leading to hypoxia, a state that results in dead zones—areas where marine life cannot exist (Cui & Roven, 2011).
3. Food Chain Impact - Persistent organic pollutants (POPs) and heavy metals can transfer up the food chain, ultimately affecting human health through seafood consumption.
4. Algal Blooms - Excess nutrients from runoff can trigger harmful algal blooms, producing toxins that pose risks to marine organisms and human health (Lfstevens, 2011).

Environmental Effects of Electronic Waste

Electronic waste is a growing concern due to the hazardous materials it contains, such as heavy metals and chemicals. The environmental effects of e-waste include:
1. Soil and Water Contamination - Improper disposal of e-waste can lead to leachate containing toxic metals like lead and mercury, contaminating soil and groundwater (Cui & Roven, 2011).
2. Health Risks - Workers in informal e-waste recycling operations can be exposed to harmful chemicals, leading to serious health problems, including respiratory issues and skin diseases (Genaidy & Sequeira, 2011).
3. Resource Wastage - Valuable materials, such as gold and rare earth metals, are lost when e-waste is not properly recycled (Miller, 2012).

Components and Chemical Properties of Municipal Solid Waste

Municipal Solid Waste (MSW) is composed of various fractions, and understanding its components is vital for effective waste management. Key components include:
1. Organic Materials - Comprising food waste, yard waste, and paper products. They are primarily biodegradable and subject to composting processes.
2. Plastics - Synthetic materials that are non-biodegradable. Plastics can persist in landfills for centuries and are often found in marine debris.
3. Metals and Glass - Recyclable materials that can be recovered and reused, reducing the overall volume of waste in landfills.
4. Hazardous Waste - Includes batteries, electronics, and chemicals that require careful handling and specific disposal methods to prevent environmental contamination.
The chemical properties of these components vary significantly, influencing waste treatment, recycling, and energy recovery methods.

Waste Disposal Techniques and Technologies

Waste disposal strategies vary based on the type of waste and its potential impacts. Common methods include:
1. Landfilling - A method of burying waste in designated sites. It is often the final disposal method, yet it poses risks of leachate and greenhouse gas emissions.
2. Incineration - Burning waste to reduce volume and potentially produce energy. However, it can generate air pollution if not adequately managed (U.S. EPA, 2014).
3. Recycling - Recovering materials from waste for reuse. This process conserves resources and reduces environmental impacts.

Improving Battery Recycling Rates

Improving battery recycling rates is critical due to the hazardous materials they contain. Strategies include:
- Awareness Campaigns - Educating the public on the importance of proper battery disposal to prevent environmental hazards and encourage recycling (U.S. EPA, 2012).
- Strategic Collection Programs - Retailers should continue to establish battery drop-off locations, making recycling more accessible for consumers (Genaidy & Sequeira, 2011).
- Legislation and Incentives - Implementing policies that require producers to take responsibility for end-of-life battery management can boost recycling rates.

Uses of Recycled Tires

Recycled tires offer numerous benefits and applications, including:
1. Road and Asphalt - Crumb rubber from tires can be used as additives in asphalt, enhancing flexibility and durability (Shulman, 2011).
2. Playgrounds and Athletic Surfaces - Recycled tires can be transformed into soft surfaces for playgrounds and sports fields, providing safety while increasing sustainability.
3. Energy Production - Tires can be used as an alternative fuel source in cement kilns, generatingenergy and reducing reliance on fossil fuels (Shulman, 2011).

Conclusion

Waste management is an intricate field involving the categorization of waste, identification of pollution sources, understanding the impacts of various types of waste, and implementing effective disposal methods. Ocean pollution, electronic waste, and tire recycling present unique challenges that require innovative solutions and public awareness to mitigate their negative effects. By improving recycling rates and finding comprehensive uses for recycled materials, we can move toward a more sustainable future and protect our environment and health.
