B.ULB: An Integrated Beauty Recycling Service
정채림,강연아,Yining Lin,이예나,Zhiyi Zheng 한국디자인트렌드학회 2022 한국디자인포럼 Vol.27 No.1
Background The effort towards sustainable development worldwide promises a more sustainable future. Of all problems, many address the environmental issue caused by plastic overusage. The beauty industry is not an exception because it is highly reliant on plastic. A beauty recycling campaign, also known as cosmetic recycling campaign, is one of the participatory campaigns established by cosmetic brands to reduce plastic waste, lessen carbon footprint, and promote the upcycling of plastic materials. The potential that this campaign holds for environmental protection is evident. With active consumer participation, people can expect positive change occurring in their surroundings. However, related studies in its consumer awareness, participation rate, and effectiveness remain at an insufficient level. Therefore, this study conducts user research on beauty recycling campaigns to suggest a service called B.ULB. The service name derives from its goal to enlighten cosmetic users on their current beauty consumption and navigate sustainable beauty practices. B.ULB offers comprehensive management of the beauty recycling campaign that tackles the existing problems of low awareness and information delivery. Methods First, the existing campaigns and studies were examined through desk research and literature review. Second, to gather user requirements and establish the design concept, surveys and semi-structured interviews were carried out. Based on the needs and requirements, two representative personas, two user journey maps, and a service blueprint were designed to develop a service model. Result User research showed that the awareness of the beauty recycling campaign is low among beauty consumers, especially female students in their 20s. However, their willingness to participate in the campaign turned out to be high, if it is more simple, convenient, and useful. Conclusion This paper is significant for revealing the problems embedded in the current recycling system of empty cosmetic containers from the perspective of users, which has been less debated over the past decade but calls for serious consideration and active engagement of both companies and consumers of the cosmetic industry.

Fracture conformance control in reservoir can effectively improve water channel to increase crude oil displacementefficiency of subsequent waterflooding. Inspired by the remarkable underwater wet adhesionof mussel byssus, hydrogel particles which can adhere stably on the fracture rock surface in reservoir conditionscould achieve long-lasting reservoir control effect. In this work, the size-controllable biomimeticfunctional hydrogel particles were prepared by mechanical shearing after bulk hydrogel was constructedby catechol-functionalized polyacrylamide and phenolic resin crosslinking agent. The influence of solutionsalinity on the aggregation and adhesion of hydrogel particles was investigated via scanning electronmicroscope (SEM), colloidal probe atomic force microscope (AFM) and quartz crystal microbalance withdissipation (QCM-D). The results showed that hydrogel particles maintained well-dispersed state in lowsalinitywater, while exhibited significant adhesion and adsorption capacity to the silica surface in simulatedreservoir salinity water. This is of great importance to the practical applications that the hydrogelparticles would not show enhanced adhesion to rock surfaces until the reservoir salinity water was met,which was beneficial to the in-depth migration of hydrogel particles to achieve effective deep reservoirprofile control. Furthermore, the visible micro-model was designed and applied to evaluate profile controleffect of hydrogel particles, and the results showed that hydrogel particles could withstand waterflushing and adhere stably to the fracture surface. The waterflooding sweep efficiency was increasedremarkably from 20.3% ± 2.0% to 38.8% ± 2.0%. This work would help better understand the functionmechanism of hydrogel particles in reservoir control and provide novel and efficient method for the practicalapplication in enhanced oil recovery.
