The cosmetic industry utilizes plastic for most of its packaging, as it is a cheap option that produces packaging that is highly durable and resistant to many chemicals. Polyethylene terephthalate (PET) is the most commonly used plastic in cosmetic packaging, and is an ideal candidate for recycling due to their short lifespan and low diffusion coefficient. However, cosmetic packaging is often not recycled properly due to its small size, contributing to the growing global plastic waste problem. If a sustainable closed-loop system was created where cosmetic packaging was created using purely recycled PET, then the amount of plastic produced could be reduced. By examining the mechanical properties of recycled composite PET from the cosmetic industry, conclusions can be drawn about its applicability in cosmetic packaging. The water absorption, UV-visible absorbance, and tensile strength was tested for recycled composite PET to predict how the material would perform if it was used in cosmetic packaging. It was found that the recycled composite PET did not perform as well as virgin PET in terms of water absorption and tensile strength, but performed similarly in reference to UV-visible absorbance. More research needs to be done to further characterize the mechanical properties of recycled composite PET before it can be used in cosmetic packaging, but this study analyzes three of the most prominent aspects found in cosmetic packaging.

The cosmetic industry has a significant lack of data on sustainability practices. The global market for cosmetics is expected to grow from $288 billion in 2021 to $415 billion in 2028 as more people populate the globe (Cosmetics Market Size, Share, & COVID-19 Impact Analysis, 2022). This research paper analyzes sustainability within the cosmetic industry. Specifically, comparing the practices between The Body Shop and Bath & Body Works. To test the hypothesis that The Body Shop is more sustainable than Bath & Body Works, a case study analysis was conducted to measure the companies’ performance in the environmental, economic, and social sectors. Comparable metrics were selected, and a pairwise comparison was completed to weigh the different metrics. To analyze the results, the Analytic Hierarchy Process (AHP) was used to ensure consistency in metric weights, and a Mann-Whitney U test was used to analyze the sector's final weights. The results verified the hypothesis that The Body Shop was more sustainable than Bath & Body Works. In all, the results support the idea that the cosmetic industry needs stronger regulations and oversight of cosmetic companies’ sustainability impact. One of the most prevalent limitations of this study is the lack of transparency and information from cosmetic companies. Moving forward, it is recommended to use data from multiple years with key performance indicators (KPIs) to assess sustainability performance more accurately.

Climate change is one of the most pressing issues of the generation. Both faith organizations and scientific research are striving to solve problems related to climate change. Both show significant motivations to act on the effects that global warming is predicted to have. Combining the motivations and finding common ground could be the key to changing the fundamental issues that lead to climate change and both sides need each other to carry out the goal of preventing climate change. Some potential outcomes of cooperation are explored and the impact that these measures could have are described. These effects will be synthesized from previous research on the subjects, compiling qualitative data on the motivations and effects of both religion and science on climate change.
