A Local Solution to Plastic Pollution
Plastic pollution is a well-known issue across the globe with staggering facts such as: “Only 9% of all plastic produced has been recycled,” and “The Great Pacific Garbage Patch is a floating island of plastic waste spanning an area that is over twice the size of the state of Texas.” Locally, this …

Seabirds as monitors of marine plastic pollution
Small buoyant plastic items are one of the most pervasive and abundant marine pollutants. They pose significant environmental impacts, including threatening the health of marine life through plastic ingestion, necessitating efforts to reduce plastic leakage into the sea. To evaluate the …

Plastic pollution: Investigating environmental pathways and critically evaluating interventions
Plastics are lightweight, versatile, and durable materials used in the manufacture of <br/>a wide range of products. Innovation in the early 1950’s facilitated a dramatic <br/>reduction in production costs with the potential to mass produce inexpensive <br/>convenience items intended for single use …

Plastic Oceans: A New Way in solving Our Plastic Pollution
<p>By 2050, the world’s oceans will have more plastic than fish with potentially catastrophic consequences on sea life and the health of the ocean. Economically, countries with coastal boundaries will be heavily impacted as plastic pollution has already generated a 13 billion dollars in monetary …

Quantifying land-based sources of plastic pollution in South Africa
It is widely claimed that at least 80% of the plastic litter entering marine environments comes from land-based sources, yet there is little empirical evidence to support this. Most studies to date predict the flux of litter from land to sea using global models based on a handful of field studies …

Multisector Mitigation of Plastic Pollution: Approaches from Biology, Policy, Law and Industry
<p>Plastic pollution is ubiquitous in the ocean. Researchers are actively determining how plastic pollution harms marine animals and which measures should be used to reduce pollution. I use the four pathways to global sustainability (created by Folke et al., 2021) as a guiding framework for this …

Disentangling entanglement in Cape fur seals for better management of plastic pollution impacts
… in summer. Most entanglement items were made of plastic, with fishing line, rope and packing straps most commonly observed. The proportion of packing straps and rope decreased slightly in recent years, whereas the proportion of fishing line was relatively constant. Items associated with fishing …

Investigating sources of microplastics and effects of plastic pollution on biofilm function in the Huron River
<p>Plastics are a global environmental threat due to mass production and the many unknowns regarding the long-term effects of plastic pollution in the environment. Microplastics (MPs) are plastic particles less than 5 mm in size, and they have become ubiquitous in aquatic ecosystems. MPs enter …

The application of environmental management accounting practices on plastic pollution control in food and beverages manufacturing firms in Durban, South Africa
In partial fulfilment of the Master of Accounting degree requirements in Cost and Management Accounting, Durban University of Technology, Durban, South Africa, 2021.

A Comparative Analysis of Plastic Pollution Distribution in Costa del Este in Panama and Central American countries: Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua
… erosion, and water filtration. However, pollution poses a significant threat. My study investigated the impacts of marine plastics, mangrove conservation practices, and waste management practices in Panama, Belize, Colombia, Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua. …

Understanding experiences of socioecological change through plastic: new methods and lessons learned
At this point, the harms of plastic-derived pollution throughout the plastic life cycle are well documented in the peer-reviewed literature. When it comes to humans, plastic impacts range from the cellular to the socio-cultural. Plastic pollution is a global environmental injustice given the …

Investigating the Impact of Health and Environmental Framing on Consumer Preference for Sustainable Food Packaging: A Choice Experiment
Plastic pollution is a growing issue that imposes not only a great environmental cost but also a great economic cost to Canada. Consequently, consumers, companies, and governments are seeking alternatives to typical PET plastic packaging, namely bioplastics. Bioplastics are seen as a more …

Inclusion of leakage into life cycle management of products involving plastic as a material choice
The accumulation of plastic waste in the natural environment has been a major environmental concern for many decades. However, the environmental impacts associated with leakage are not taken into consideration under current life-cycle based approaches, despite packaging being a major application …

Unwanted Project: Speculative Design for Circularity
More than 360 million tons of plastic are produced each year (2020, global plastic report), and only 9% can be recycled properly. With increasing climate change and the inevitable single-use waste stream produced in our everyday life, plastic pollution is rapidly outpacing the current effort to …

Salvaging meaning : exploring the language of inflatable kinetic sculptures and the materiality of plastic
… refabrication through the use of discarded plastic. This body of work highlights the relationship between industrialisation, plastic goods and nature. The insubstantial, flimsy qualities of the inflatable are an extended metaphor for the fragility of ecologies and the impact of plastic …

Connecting consumer plastic formulations to marine fates and impacts
Solutions to plastic pollution have been impeded by knowledge gaps surrounding plastic’s environmental persistence and implications. To fill some of these gaps, this thesis aims to connect consumer plastic formulations (the specific mixture of polymers and additives) to marine fates and impacts. …

Plastics and Microplastics as Vectors for Bacteria and Human Pathogens
<p>Since plastics degrade very slowly, they remain in the environment on much longer timescales than most natural substrates and can thus provide a novel habitat for colonization by bacterial communities. The full spectrum of relationships between plastics and bacteria, however, is little …

Connecting Consumer Plastic Formulations to Marine Fates and Impacts
Solutions to plastic pollution have been impeded by knowledge gaps surrounding plastic’s environmental persistence and implications. To fill some of these gaps, this thesis aims to connect consumer plastic formulations (the specific mixture of polymers and additives) to marine fates and impacts. …

Novel Photopolymers for Additive Manufacturing
… printing conditions such as UV light, the plastic pollution caused by the wasted products, or finite functionalities of the products may limit the further application of the final manufactured products. In light of the current challenges, this thesis is directed at the design and …
