RELEASE OF MICRO- AND NANOSCALE PLASTICS FROM SYNTHETIC TEXTILES DURING LAUNDRY AND QUANTIFICATION OF NANOSCALE PLASTICS BY SINGLE PARTICLE INDUCTIVELY COUPLED PLASMA MASS SPECTROMETRYMahbub, Md Shahriar 01 May 2022 (has links)
Plastic wastes released in the environment can produce microplastics (MPs, Size < 5 mm) and nanoscale plastics (NPs, Size < 100 nm) due to the environmental weathering processes. The presence of the MPs and NPs have been found worldwide in different aquatic and terrestrial environments. These tiny plastics have detrimental health impacts when they are ingested or inhaled by aquatic organisms as well as human beings. However, their occurrences including identification and quantification in the environment are still a great challenge. Particularly, quantification for NPs is a challenge, as there is no standard technique available yet that can count the NPs effectively. Therefore, this thesis was focused on two important aspects related to microplastics (MPs) and nanoscale plastics (NPs). Firstly, assess the source of MPs or NPs release and secondly, NPs quantification. Microfibers (MFs) are one of the most abundant portions of MPs in the aquatic environment, which are shed during the washing and drying of fabrics. Hence, in the first area of the study, the release pattern of MPs, in the form of acrylic MFs from portable washer and dryer during fabric washing and drying under different conditions were investigated. Additionally, the subsequent degradations behavior of these released MFs under ultraviolet light (UV-A) irradiation were explored. The results indicated that the MFs were released almost 2 times higher when the fabrics were washed for 60 min compared to 30 min due to higher mechanical stresses. In addition, MFs released were increased by 1.4 times higher when the fabrics were dried for 60 min compared to 30 min due to longer rotational forces on the fabrics. The use of detergent during washing promoted 2.7 times more MF release compared to without detergent. Moreover, MFs were released approximately 1.8 times higher from washing when washed with 40°C of water than with 20°C of water. However, subsequent washing cycles showed decreasing patterns of MF releases during washing and drying, approximately 45% less and 67% less, respectively in the 7th wash compared to the 1st wash as the fabrics approach a plateau. The released acrylic MFs were analyzed after their exposure to UV-A irradiation in the aquatic environment from 0 day to 182 days. After 182 days of UV-A irradiation, released acrylic MFs showed significant changes in the surface morphology in the form of cracks, holes, and flakes determined by scanning electron microscope (SEM). The formations of cracks, cavities, and flakes in the MF’s surface were proportional to the period of UV-A exposure. Dimensions of the formed holes and cracks on the UV-A degraded MFs suggested that MFs can turn into NPs in presence of water and UV-A exposure in the environment. Hence, a robust analytical tool must be optimized to detect these tiny degraded NPs in the aquatic environment. This brings to the second area of the study which aimed to optimize and validate a method to detect NPs through coating with synthesized gold nanoparticles (AuNPs) by Single Particle Inductively Coupled Plasma Mass Spectrometry (SP-ICP-MS). This study successfully detected the polystyrene nanoscale plastics (PS NPs, size 61 nm) by particle-by-particle analysis in single quadrupole-based SP-ICP-MS and the detection limit of particle number concentration was reached up to 8.64 × 10^7 particles/L. PS NPs were selected as a model nanoscale plastic as it is one of the most abundant plastics in the environment. The method was applied to PS NPs in deionized (DI) water which achieved a good amount of PS NP recoveries by up to 98%. This analytical technique can be further optimized and might be helpful for analyzing NPs in any environmental samples to determine their occurrences and concentrations.

Identifying reverse exchange practices: a comparative study of laundry logistics in public hospitals (Thailand)Bandoophanit, T., Breen, Liz 09 July 2018 (has links)
Yes / The effective reverse exchange of healthcare products such as laundry within a hospital environment can support the health system, for achieving the highest goal: ‘to provide regular and timely supply of clean linen to the satisfaction of patients and staff’ (Srikar et al., 2015, p. 593). Previous studies by Bandoophanit et al. (2015, 2017) assert there are constant shortages of linen availability in many Thai public hospitals which can undermine the efficacy of laundry management and quality of medical treatment. This study investigates the practices, culture, and operational performance of three large-sized public hospitals (700-2,000 beds) located in Thailand reflecting on the application of Reverse Exchanges (R/E) theory. This study contributes to the Thai healthcare agenda, a core mission of which is to “Develop the health system with quality, efficiency and equality; with participation of the people, communities and all sectors for good health of all Thai people in order to achieve a good and sustainable society following the King’s Sufficiency Economy philosophy” (Ministry of Public Health, 2018).

Småskalig eller industriell tvätt och hantering av sängkläder inom hotellbranschen : En jämförelse i miljöbelastningJohansson, Erica, Dennisson, Anne January 2018 (has links)
Hotellbranschen är en konstant växande verksamhet och med fler sängar att bädda tillkommer fler lakan att tvätta. Idag kan hotell välja att använda sig utav externa tvätterier som hämtar upp, tvättar och levererar rena sängkläder men kan även välja att själv tvätta sängkläderna lokalt på hotellet. Två olika tvätthanteringssystem som innebär skillnad i både tvätt- och torkprocesserna, något som i sin tur leder till att materialet samt miljön påverkas annorlunda. I en tid då hållbarhet är en prioriterad fråga miljöanpassar många sin verksamhet och för att öka medvetenheten kring det val om hur sängkläder på ett hotell hanteras mest miljöeffektivt, tar denna rapport upp skillnaderna i miljöbelastning då man tvättar industriellt kontra småskaligt. Miljöbelastningen presenteras som koldioxidutsläpp, vatten- och kemikalieförbrukning samt genom skillnader på vävars förslitning inom de olika processerna. Den vanligaste väven för hotellsängkläder inom tvättservice är polycotton medan sängkläder av bomull är mer vanligt vid småskalig tvätt. Testerna utförs därför på en polycottonväv, två olika bomullsvävar samt en väv av både bomull och lyocell för att få ett så brett resultat som möjligt och utforska vad som fungerar. Materialen genomgår 50 tvättar vid industritvätt och 50 tvättar inom en småskalig tvätt för att sedan testa hur de påverkats från otvättat material i cykler om 25 tvättar. Resultaten indikerar på att det finns tydliga skillnader mellan de olika tvätthanteringarna både i hur de påverkar materialen samt ur miljösynpunkt. Då industriell tvätt under en längre period aktivt jobbat mot en mera hållbar affärsmodell och därmed effektiviserat tvättprocessen har det lett till minskad miljöbelastning inom de presenterade faktorerna. Vid leverans till och från tvätteriet är det dock idag fortfarande vanligt att lastbilar används, transportsträckan till hotellet i fråga blir därmed avgörande vid viktning av total miljöbelastning. Det framkommer att sängkläder av polycotton kan ha en likvärdig livslängd som bomull trots sin överlägset höga fysiska slitstyrka på grund av materialets tendens till noppbildning. Hotellbranschen har höga visuella krav på sina textilier och kan därför komma att kassera en vara av polycotton innan det är fysiskt utslitet. / The hotel industry is a constantly expanding business and with several beds to make, more sheets needs to be washed. Today, hotels can choose to use external laundry service that pick up, wash and supply bedding back to the customer. However you can also choose to wash your own bed linen at the hotel. The two different laundry management systems involve differences in both the laundry and the drying processes, which in turn affects the material and environment differently. In a time when sustainability is a prioritized question, people adapt their business to become more eco-friendly. To raise awareness about how bedding in a hotel most efficiently is managed, this report presents and clarifies the differences between industrial versus small scale laundry. The environmental impact is presented as carbon dioxide emissions, water and chemical consumption and how the woven materials handle the different processes. The most common fabric for hotel bedding in the textile service sector is polycotton, while cotton fabric is more common in small-scale laundry. The fabric of test-specimens is chosen to present the widest possible results within a lifelike perspective. Therefore, bedding made of polycotton, a mix between cotton and lyocell and two different cotton fabrics are picked for the tests. The materials undergo 25 and 50 wash cycles for industrial and small-scale laundry before the materials is tested to show how they were affected compared to unwashed fabric. The results indicate that there are distinct differences between the different laundry managements, both in terms of how they affect the material and from an environmental point of view. Since industrial laundry for a long period of time actively has worked towards a more sustainable business model and thus streamlined the washing process, it has resulted in major environmental benefits. However, in the case of delivery to and from the laundry facility, it is still common for trucks to be used. The transport distance to and from the hotel in question therefore becomes crucial when making the choice of the most suitable laundry management.

Exploring the implications of cultural context for design for sustainable behaviourSpencer, Jak January 2014 (has links)
In this thesis the opportunities for designing products that are less resource intensive during use, in different cultural contexts is investigated. The research was divided into four phases: an extensive literature review, an online scoping study, an intensive qualitative study on laundry behaviours, and an international design competition. The research drew on the background of design for sustainable behaviour, a relatively new field of enquiry concerned with reducing the social and environmental impacts of products during their use. Despite the increasing development of theories to change user behaviour through design, there is a lack of understanding of how different cultural contexts affect behaviour. An extensive literature review established the current thinking on culture, development, and behaviour. The diverse nature of everyday household behaviour from different cultures and the effect it has on household resource consumption was uncovered and was investigated further in an online scoping study. In the study, participants from the UK, Brazil and India answered questions related to the themes of food, water, energy, materials and government schemes. The findings helped to highlight the differences in household behaviours and led to more detailed investigation of laundry behaviours in three sites in the UK, Brazil and India using in-context interviews, observations and household tours. From these findings a series of culturally significant and culturally independent factors were established that can aid designers in understanding behaviours in a given context. A set of design guidelines were also created to facilitate the design of less resource intensive products during use. These were then tested with designers in an international design competition answering a brief to design a less resource intensive laundry process. The research suggested a range of benefits for designers studying other cultures. The guidelines and cultural factors created can help designers to build empathy with users in a given context and boost creative thinking for more sustainable solutions. The research also offered insights into the possibility of, and application for, transferring behaviours between contexts as well as a new understanding of the aspirations of consumers in emerging markets, which could support other theories of sustainable development, such as leapfrogging.
