Abstract:
AbstractThe “plastics revolution” of the last quarter century disrupted a hospital tradition. Since the 1890s, hospitals processed, packaged, and sterilized most of the medical-surgical items they needed in their own sterile supply departments–a “cottage industry” developed specifically for recycling. Only those consumable items that were too difficult, expensive, or inconvenient to reprocess were purchased from outside manufacturers as presterilized, single-use “disposables.” Since the plastics revolution, however, the “disposables” started to displace the “reusables,” and while claiming to be an economical innovation, have become a significant item in the budget. Some hospitals feel that if disposables save money, reusing the disposable several times will save more. The practice is spreading. The manufacturers, in turn, claim that hospitals do not have adequate quality assurance programs or skills to reprocess their items properly. The debate is further complicated by legal and ethical ramifications, as well as commercial and economic arguments.

Abstract:
There is an imperative need to reduce disposable plastics and enhance the value of plastic waste. Stakeholders from the HORECA network and the general public participated in 11 awareness actions at Minho river, riverbanks, and at Caminha beach. The aim of these actions was to raise awareness about plastic reduction from land-based sources into the oceans, especially single-use plastics. Over 4.300 plastics were collected and organized in a TOP 5 of predominance: Fragments (< 2,5 cm); Cigarette butts; Fragments (> 2,5 cm); Cotton buds; Bio filters pieces. A digital pedagogical “Collection Litter 365” was created with photographs of waste removed from the aquatic environment and art works that used it as raw material for the artistic process. Simultaneously, 42 restaurants, cafes, hotels and accommodation establishments were surveyed and motivated to eliminate or minimize the use of disposable plastics and improve it's separation for recycling. Plastic water bottles (43%), plastic straws (40%) and plastic bags with handles (26%) were the most decreased items. Plastic separation for recycling reached 29%. Art works were exhibited in Minho river, at the Art Biennale of Cerveira and disseminated via digital communication. These actions were performed during LowPlast Project, promoted by Aquamuseu do rio Minho - Vila Nova de Cerveira Municipality, in partnership with the Portuguese Marine Litter Association, the Foundation Biennale of Art of Cerveira and the Interdisciplinary Art Institute - DTK, in Norway, and financed by EEA Grants. https://aquamuseu.cm-vncerveira.pt/pages/893.

Abstract:
Plastics are inexpensive, lightweight and durable materials, which can readily be moulded into a variety of products that find use in a wide range of applications. As a consequence, the production of plastics has increased markedly over the last 60 years. However, current levels of their usage and disposal generate several environmental problems. Around 4 per cent of world oil and gas production, a non-renewable resource, is used as feedstock for plastics and a further 3–4% is expended to provide energy for their manufacture. A major portion of plastic produced each year is used to make disposable items of packaging or other short-lived products that are discarded within a year of manufacture. These two observations alone indicate that our current use of plastics is not sustainable. In addition, because of the durability of the polymers involved, substantial quantities of discarded end-of-life plastics are accumulating as debris in landfills and in natural habitats worldwide. Recycling is one of the most important actions currently available to reduce these impacts and represents one of the most dynamic areas in the plastics industry today. Recycling provides opportunities to reduce oil usage, carbon dioxide emissions and the quantities of waste requiring disposal. Here, we briefly set recycling into context against other waste-reduction strategies, namely reduction in material use through downgauging or product reuse, the use of alternative biodegradable materials and energy recovery as fuel. While plastics have been recycled since the 1970s, the quantities that are recycled vary geographically, according to plastic type and application. Recycling of packaging materials has seen rapid expansion over the last decades in a number of countries. Advances in technologies and systems for the collection, sorting and reprocessing of recyclable plastics are creating new opportunities for recycling, and with the combined actions of the public, industry and governments it may be possible to divert the majority of plastic waste from landfills to recycling over the next decades.

Abstract:
Disposable plastics are drawing considerable attention as a source of environmental risk despite their benefits in daily life. Banning the use of disposable plastics could increase other types of risks, which may damage the public good in the long run. Considering the trade-off of the risks and benefits, one way to improve social welfare is to conduct proper recycling and to continue using plastics but limit them to essential use, avoiding an unnecessary ban. A potential barrier to such a policy might be risk-averse attitudes toward actions that are perceived to threaten future generations, which is a well-known phenomenon. We previously designed a framework for information provision using messages that remind individuals about familial support, which had significant effects in multiple countries on increasing positive attitudes toward air pollution caused by industrialization. We hypothesized that this information provision could also be effective for disposable plastic use. Thus, we conducted a randomized controlled trial via online surveys in Japan, Canada, and the US to identify the effects of our designed messages about recycling on increasing positive attitudes toward disposable plastics. The intervention effects were measured by the difference-in-difference method and panel analysis based on linear regression models using the respondents’ attributes and personality traits. The effects were consistently correlated with a sense of familial support, with the effect sizes varying according to country (US > Japan > Canada). Attributes that positively contributed to the message being more effective were higher agreeableness, lower Machiavellianism, lower psychopathy, and being a woman. Although personal fear about COVID-19 moderated the message effects, concern about the threats to relatives and family boosted the effects. Although the effect sizes were influenced by external factors, the results suggested that our proposed framework for information provision has the potential to be applied to a wider variety of risk-related topics.

Abstract:
The marine environment is facing the threat of increasing plastic pollution, especially from disposable plastics. Presently, governments worldwide are promoting policies to restrict or prohibit conventional plastics. As one hopeful alternative to conventional disposable/non-durable plastics, biodegradable plastics have attracted much attention and controversy in terms of their definition, environmental impact, and environmental significance, as they may be widely used. Therefore, it is necessary to clarify the facts about biodegradable plastics, understand the current knowledge gaps, and identify promising fields of relevant research. This review briefly introduces some common biodegradable plastics, their mechanisms of biodegradation, indicators for the biodegradation process, and factors concerning biodegradability and summarizes studies on the biodegradation of biodegradable plastics in the marine environment. The lifespan of biodegradable plastics varies greatly due to their compositions/properties as well as significant differences in the marine environment. Then, the potential risks of biodegradable plastics, including the release of pollutants (micro/nanoplastics, degradation products, and additives), adsorption-desorption of pollutants (pesticide, etc.), and their impact on biomes and biogeochemical cycles are discussed, fully revealing their possible impacts on the marine environment. It is believed that, in addition to the waste of resources, a high abundance of microplastics, toxic leachates, and complex effects on habitats and the environment may also cause problems for the marine environment as a result of the widespread and inappropriate use of biodegradable plastics. Based on the discussion, some constructive suggestions on how to use biodegradable plastics reasonably and prudently in the future are put forward.

Abstract:
Plastic pollution has become one of the most serious environmental issues worldwide. Plastics can contain high amount of additives (e.g., phthalate, bisphenol A, trace metals), and they could be leached out of plastics, enter the aquatic environment and cause toxic effects to aquatic organisms (including microcrustacean). In this study, we investigated chronic effects of plastic leachates from two popular plastic materials (garbage bag and disposable raincoat) on the survival, maturation and reproduction of the microcrustcean Daphnia magna. The results showed that, the plastic leachates from the two materials at the concentration up to 1000 mg/l did not cause negative effect on survival of D. magna. However, exposed to the leachates from the garbage bag (at the concentrations of 10, 100 and 1000 mg/l) and from the disposable raincoat (at the concentration of 10 mg/l), the animals delayed their maturity ages compared to the control. Besides, the two kinds of leachates at the concentration of 1000 mg/l stimulated the reproduction of D. magna, resulting the increase of 17 – 37% of total offspring compared to the control, during 21 days of experiment. The results of this study contribute to the understanding on the toxicity of popular plastic materials to the microcrustacean, D. magna. Additionally, the plastic usage and emission into the environment should be paid more attention to protect the aquatic ecosystems and human health.

Abstract:
This research assessed the viability to use disposable diapers as a substrate for the production of biohydrogen, a valuable clean-energy source. The important content of cellulose of disposable diapers indicates that this waste could be an attractive substrate for biofuel production. Two incubation temperatures (35 °C and 55 °C) and three diaper conditioning methods (whole diapers with faeces, urine, and plastics, WD; diapers without plastic components, with urine and faeces, DWP; diapers with urine but without faeces and plastic, MSD) were tested in batch bioreactors. The bioreactors were operated in the solid substrate anaerobic hydrogenogenic fermentation with intermittent venting mode (SSAHF-IV). The batch reactors were loaded with the substrate at ca. 25% of total solids and 10% w/w inoculum. The average cumulative bioH2 production followed the order WD > MSD > DWP. The bio-H2 production using MSD was unexpectedly higher than DWP; the presence of plastics in the first was expected to be associated to lower degradability and H2 yield. BioH2 production at 55 °C was superior to that of 35 °C, probably owing to a more rapid microbial metabolism in the thermophilic regime. The results of this work showed low yields in the production of H2 at both temperatures compared with those reported in the literature for municipal and agricultural organic waste. The studied process could improve the ability to dispose of this residue with H2 generation as the value-added product. Research is ongoing to increase the yield of biohydrogen production from waste disposable diapers.

Abstract:
Study of the Biodegrability of Degradable/Biodegradable Plastic Material in a Controlled Composting EnvironmentThe objective of this study was to determine the degrability/biodegradability of disposable plastic bags available on the market that are labeled as degradable/biodegradable and those certified as compost. The investigated materials were obtained from chain stores in the Czech Republic and Poland. Seven kinds of bags (commercially available) were used in this study. One of them was a disposable bag made of HDPE and mixed with totally degradable plastic additive (TDPA additive). Another was a disposable made of polyethylene with the addition of pro-oxidant additive (d2w additive). One was labeled as 100% degradable within various periods of time, from three months up to three years, and four were certified as compostable. The test was carried out in a controlled composting environment. The biodisintegration degree of the obtained pieces was evaluated following a modified version of ČSN EN 14806 Norm "Packaging - Preliminary evaluation of the disintegration of the packaging materials under simulated composting conditions in a laboratory scale test" and a modified version of ČSN EN ISO 20200 "Plastics - Determination of the degree of disintegration of plastic materials under simulated composting conditions in laboratory-scale test" (ISO 20200:2004). The emphasis was put on determination whether the bags are degradable/biodegradable or not.

Abstract:
As the bottled water trend continues to rise across the nation, drinking water utilities have become more concerned with ensuring consumer satisfaction of their product. Although public water supplies are safeguarded by regulations, aesthetically unappealing taste-and-odor problems have led consumers to search for alternative water sources, such as bottled water or tap water processed by point-of-use filters. Consequently, taste-and-odor monitoring has become important to the drinking water industry. Because many utilities use chlorine to disinfect the water, chlorine odor often masks other more subtle odors that may eventually cause consumer complaints. As treated water travels from the water treatment plant to the consumer, chlorine residual diminishes and may reveal a water's naturally less-pleasing odors. Consequently, odor monitoring at the water treatment plant, where chlorine concentrations are at a peak, may not identify potential displeasing smells. Proper evaluation of these odor-causing substances requires that the chlorine odor first be eliminated before evaluating any remaining odors. Dechlorinating agents can remove chlorine, but some will produce other unwanted odors or even remove certain odorous compounds. This research describes the efficiency of several of these agents (ascorbic acid, hydrogen peroxide, oxalic acid, sodium nitrite, and sodium thiosulfate) in dechlorinating chlorinated solutions of the earthy-smelling compound geosmin and musty-smelling MIB. Interfering odors in reusable containers pose another problem in drinking water odor analysis. The most common odor-analysis methods (TON and FPA) involve the use of glass flasks, which often either develop chalky odors or have persistent lingering odors from previous evaluations. Furthermore the glass flasks break easily and are difficult to clean. This research also evaluates the suitability of four types of disposable plastic containers for odor analyses.

Mestrado em Ciências Empresariais
O plástico é um material importante e omnipresente na economia e na vida quotidiana. Tem diversas funções que ajudam a enfrentar uma série de desafios com que a sociedade se depara. Porém, o modelo linear da cadeia de valor dos plásticos, i.e, a sua produção, utilização não permite captar os benefícios ambientais e potencialmente económicos de uma abordagem mais ?circular? prejudicando o ambiente. Existe a necessidade de combater os problemas ambientais que ensombram os plásticos e o sector das embalagens alimentares começa a responder a esta necessidade. O LoureShopping pretende implementar um projeto pioneiro na sua área de alimentação correntemente designada pelo seu nome inglês de foodcourt, procurando, em parceria com os seus lojistas da restauração, encontrar formas de reduzir significativamente a utilização de plástico de uso único cedido aos consumidores. A autora, em coordenação com as equipas do LoureShopping, do Sustainability Office e da empresa NOWA, procurou estudar o problema da utilização de materiais descartáveis no foodcourt do LoureShopping. Através de entrevistas estruturadas aprofundadas com os lojistas e questionários quantitativos ao consumidor, percebeu-se quais os itens que podem ser mais facilmente eliminados ou substituídos e quais os que oferecem maior dificuldade ou entraves ao seu desaparecimento. Perceber-se-á, ao longo do relatório de estágio, que há vontade genuína, quer da parte dos lojistas, quer da parte dos consumidores em participar neste projeto, nomeadamente reduzindo a utilização e consumo de plásticos descartáveis.
Plastic is an important and ubiquitous material in economics and everyday life. It has a variety of functions that help to address a number of challenges facing society. However, the linear model of the plastics value chain, i.e. its production and use, does not capture the environmental and potentially economic benefits of a more ?circular? approach that harms the environment. There is a need to tackle the environmental problems that plague plastics and the food packaging sector is beginning to respond to this need. LoureShopping intends to implement a pioneering project in its food area commonly referred to by its English name of foodcourt, seeking, in partnership with its restaurant retailers, to find ways to significantly reduce the use of single-use plastic sold to consumers. The author, in coordination with the teams of LoureShopping, Sustainability Office and NOWA, sought to study the problem of using disposable materials in LoureShopping's foodcourt. Through in-depth structured interviews with shopkeepers and quantitative consumer questionnaires, it was realized which items can be most easily eliminated or replaced and which offer the greatest difficulty or barriers to their disappearance. It will be apparent from the internship report that there is genuine willingness on the part of both retailers and consumers to participate in this project, in particular by reducing the use and consumption of disposable plastics.

Plastics, a petroleum-based product, are widely used in manufacturing disposable products and have created a solid waste issue. Due to their abundant supply, and given their high energy content, their use for power generation is of technological interest. However, whereas waste plastics have found limited use in incineration, such a conventional direct combustion technique is ill-controlled and produces considerable amounts of health-hazardous airborne compounds. Thus, an alternative technology is proposed herein to further address our increasing energy needs and, at the same time, utilize our waste plastics streams in an environmentally-benign manner. More specifically, a multi-step process/device is proposed to accept post-consumer plastics, of various types and shapes, and generate an easily-identifiable form of energy as a final product. To achieve low emissions of products of incomplete combustion, the plastics are liquefied, pyrolyzed, mixed with air, ignited and, finally, burned forming pre-mixed low-emission flames. Combustion is thus indirect, since the solid polymer is not directly burned, instead its gaseous pyrolyzates are burned upon mixing with air. Thereby, combustion is well-controlled and can be complete. A demonstration device has been constructed to convert the internal energy of plastics into clean thermal energy and, eventually to electricity.

Abstract:
Engineers, policy makers, and managers have shown increasing interest in increasing the sustainability of products over their complete lifecycles and also from the ‘cradle to grave’ or from production to the disposal of each specific product. However, a significant amount of material is disposed of in landfills rather than being reused in some form. A sizeable proportion of the products being dumped in landfills consist of packaging materials for consumable products. Technological advances in plastics, packaging, cleaning, logistics, and new environmental awareness and understanding may have altered the cost structures surrounding the lifecycle use and disposal costs of many materials and products resulting in different cost-benefit trade-offs. An explicit and well-informed economic analysis of reusing certain containers might change current practices and results in significantly less waste disposal in landfills and in less consumption of resources for manufacturing packaging materials. This work presents a method for calculating the costs associated with a complete process of implementing a system to reuse plastic containers for food products. Specifically, the different relative costs of using a container and then either disposing of it in a landfill, recycling the material, or reconditioning the container for reuse and then reusing it are compared explicitly. Specific numbers and values are calculated for the case of plastic milk bottles to demonstrate the complicated interactions and the feasibility of such a strategy.

Abstract:
Abstract The polyethylene terephtalate (PET) is a polymer with a high melting (265°C) and glass transition (67°C) temperatures, insensitive to moisture and common solvents. Also it has an wide range of mechanical properties attainable by variations of molecular weight, orientation and crystallinity. Due to these characteristics allied with the glass-like transparency, light weight and unbreakable character, PET is used to form high performance bottles for carbonated soft drinks, wines, beers and food packing. The world annual consumption of PET for these purposes is increasing, with impressive prospects for the future. This characteristic leads to other situation. The consumption of energy and natural resources together with the environmental problems caused by disposable plastics, make the engineering and materials scientists try to find for different ways to recycled plastics. The characteristics of PET mentioned above seen to be very proper to use as a material for coating.

Abstract:
Plastics are the choice materials for fabrication of many microfluidic devices as mass production methods such as the injection moulding and hot embossing processes can be used for disposable polymer device fabrications. However, fabrication of mould inserts with micro features is a very critical step towards successful moulding of polymer micro components. Due to technical limitations many micro features cannot be fabricated directly onto metal mould inserts. Silicon based micro machining technologies, on the other hand, are well developed and are capable of producing very fine micro structures. In the study, silicon insert moulding method is developed for fabrication of polymeric biochips. Although it has been reported to use silicon dies for hot embossing applications, careful consideration of mould design is required to use fragile silicon inserts in moulding applications where higher mould clamping forces are encountered. Silicon inserts instead of traditional metal inserts, are successfully manufactured and used for polymer biochip moulding. It has been found that the silicon inserts can last for tens of shots if properly installed in an injection mould.

Abstract:
The consumer products industry is a good example of broad usage of disposable products. Consumer disposable products, in general, have two key unique characteristics that are very important drivers for new product inventions: low cost and large volume scalability. These two properties have always limited the penetration of MEMS technology into the consumer disposable product industry. Even though MEMS is traditionally spoken of as a low cost high volume technology, this holds true for industries outside the one described within here. The reality surrounding traditional silicon MEMS technology is that the cost structures is at best two orders of magnitude above acceptable levels and the infrastructure available to make the needed volumes is non existent. For these two reasons, plastic microfabrication and scalable design principles adaptation offers a viable solution for MEMS technology within the context of disposable consumer products. Using our low cost, large volume scalable plastic microneedle technology as an example, it was demonstrated that a successful transition from silicon to plastic microfabrication was achieved while maintaining excellent structural functionality for the purpose of glucose sensing from interstitial fluid (ISF).

Abstract:
A great deal of energy can be sourced both directly and indirectly from waste. For example, municipal waste with an energy content of around 60 petajoules is incinerated in Switzerland every year. The energy recovered directly from this waste covers around 4 % of the Swiss energy demand. However, the greatest potential offered by waste management lies in the recovery of secondary raw materials during the recycling process, thus indirectly avoiding the energy-intensive production of primary raw materials. In order to optimise the contribution to the energy turnaround made by waste management, as a first step, improvements need to be made with respect to the transparent documentation of material and cash flows, in particular. On the basis of this, prioritisation according to the energy efficiency of various recycling and disposal channels is required. Paper and cardboard as well as plastic have been identified as the waste fractions with the greatest potential for improvement. In the case of paper and cardboard, the large quantities involved result in considerable impact. With the exception of PET drinks bottles, plastic waste is often not separately collected and therefore offers substantial improvement potential. Significant optimisation potential has also been identified with regard to the energy efficiency of incineration plants. To allow municipal solid waste incineration (MSWI) plants to use the heat they generate more effectively, however, consumers of the recovered steam and heat need to be located close by. A decisive success factor when transitioning towards an energy-efficient waste management system will be the cooperation between the many stakeholders of the federally organised sector. On the one hand, the sector needs to be increasingly organised along the value chains. On the other hand, however, there is also a need to utilise the freedom that comes with federal diversity in order to test different solutions.
