Bacteria serve up a tasty solution to the global plastic problem

Rattling around on a cold, damp Edinburgh street, a plastic water bottle is a stark reminder of one of the greatest environmental crises facing our planet. In little under 100 years a growing tsunami of plastic waste has contaminated not just our streets but nearly every corner of the natural world – from Mount Everest to the deepest oceans. But this plastic bottle provided the inspiration that could yet turn the tide. Diverted from landfill to the laboratory the bottle soon grabbed the attention of the world’s media by undergoing a remarkable transformation from plastic into vanillin – the main component of vanilla and one of the most in-demand spices in the world. This seemingly impossible act of alchemy was made possible by harnessing the metabolic power of bacteria. Its success has enormous implications. Not only could it meet our insatiable appetite for this rare flavouring, but it could radically change the way we tackle another addiction – the endless stream of single-use and disposable plastics that have become part of everyday life. Yet this only scratches the surface of the potential of this approach. By coaxing microbes to behave as eco-friendly factories that produce useful materials, we could tackle many other global challenges.

Lunch Box Innovation Product Design In The Millennial Era

Almost of kids in the world still bring a lunch box and a bottle of water in their bag when their go to school. His mother always prepares a lunch box complete with a bottle of drinking water, hoping that his son can enjoy his favorite lunch and avoid starvation. Sometimes the mother is very worried when the lunch box has been brought by the child but the water bottle is left behind. Then the mother was willing to take her child's water bottle to her school. This is certainly not expected by either the mother or the child. As a form of concern for the author to this problem, the author proposes a lunch box design with a lunch box lid that also functions as a drinking water bottle. The idea of this design proposal is ones grab, both are food & drink in your hand. The goal is how to make a kids can grab their food and drink easily and practice. So it is proposed to modify a top cover of common foodpack to become a drink bag. The design process begins with analyzing market needs, making sketches, creating 3D design models using the Autodesk Inventor CAD application, material selection, and product evaluation.

Social Comparison Information Influences Intentions to Reduce Single-Use Plastic Water Bottle Consumption

Single-use plastic consumption is at an all-time high and threatens environmental and human health. College campuses in particular serve as a hub for single-use plastics due to their convenience for students on the go. The present research tests whether social comparison information can influence self-perceptions of single-use plastic consumption and motivate behavior change within the college campus environment. In a controlled experiment, we measured college students' existing plastic water bottle usage and gave them false feedback about their behaviors and relative standing to their classmates: participants in comparison conditions learned they were either above or below average in their plastic water bottle sustainability behaviors. Results indicated that (relative to a no-comparison control), being above average at water bottle sustainability led students to be more satisfied with their sustainability efforts. However, either kind of comparison information (i.e., being above or below average) led to greater behavioral intentions to reduce single-use plastic water bottle consumption in the future. This study highlights how comparison information can be used to motivate sustainable behavior change with regards to single-use plastics.

Stop Piling on: Assessing Efforts to Reduce Single-Use Water Bottles at Allegheny College

Plastic waste represents one of the largest environmental problems of the modern era and disposable water bottles comprise a substantial portion of that waste in the U.S. Colleges are in a unique position to create systems that foster sustainable behaviors among their constituents. Since 2015, Allegheny College has installed water refill stations, and initiated a free water bottle program and an awareness campaign to reduce single-use bottles on the college’s campus. Two surveys were distributed to the student body between 2018 and 2019 to assess the efficacy of those initiatives and learn about any barriers. Bottled water use has reduced significantly since 2014, with the majority of students stating that they most commonly drink water from refill stations while on campus. Demographic factors like income, sex, or place of origin were not related to the amount of bottled water consumption or type of water preference among students. The primary barrier to students eliminating disposable water bottle use was found to be a lack of water refill stations in dormitories. Research aimed at changing behaviors to benefit the environment should consider the barrier of convenience. This research provides a valuable lesson that can extend beyond college campuses and into public settings.

An unusual presentation to the burn’ unit – a cautionary tale

We report a case of a 34-year old female with systemic lupus erythematosus (SLE) and lupus nephritis who was referred to the regional burns service with a suspected contact burn to the left flank and hypogastrium from a hot water bottle. The patient had been applying a hot-water bottle to the area at night for pain relief and after 3-days she noticed a localised area of erythema which became larger and began to blister over a period of 5-days. The blistered areas were erythematous and wet, however the capillary refill time was sluggish. The lesion was initially diagnosed and treated as a superficial partial thickness burn that had developed secondary to prolonged contact with a hot water bottle. However, due to the history of immunosuppression as well as elements of the lesion being unusual for a burn, we consequently diagnosed this as herpes zoster infection. This case highlights the importance of always thinking of alternative diagnoses. There are several cases in the literature where shingles has been dangerously misdiagnosed, furthermore leading to patients being mistakenly treated and even operated on. In the early stages, abdominal shingles may present very similarly to superficial partial thickness burns, both with neuropathic pain, erythema and blistering. It is important for the burns surgeon to be aware of this diagnosis as a differential in atypical presentations, and to pay particular attention to the timeline of events is the key to diagnosis.

A STUDY INTO DESIGNING AN AMBIENT WATER BOTTLE THAT SUPPORTS USERS' WATER-INTAKE TRACKING PRACTICES

Taking on the challenge of motivating users to drink water regularly, we designed a smart water bottle that can track water intake behavior and inform users about this behavior through ambient feedback. We then conducted two studies to explore the bottle's feedback design from the perspective of users and designers. First, we conducted semi-structured interviews with 10 prospective users and found that they would like to receive personalized, precise, gamified and reminding feedback. Second, we conducted a design workshop with 13 professional designers to explore the range of visualizations that can be used to give feedback. Analyzing these visualizations, we identified three reminder types (augmenting, restoring and balancing) and six visualization styles grouped according to three dimensions of ambient displays (representation fidelity, notification level, aesthetic emphasis). In this paper, we first explain our water bottle concept along with existing solutions. Then, we report the results of these studies. Finally, we discuss the potential implications of the results for our own work as well as for designing ambient displays aimed at supporting users' water intake tracking practices.
