Abstract

Climate change and rising global temperatures are a serious cause for concern. It is paramount to manage the impending harmful and potentially severe environmental consequences. One way to manage climate change is through the reduction of greenhouse gas emissions. This can be achieved by improving conventional cooling systems of buildings, a major contributor to greenhouse gas emissions. Hybrid aerogel made from recycled polyethylene terephthalate (rPET) and polyvinyl alcohol (PVA) is proposed as a potential solution to improve energy efficiency. The developed rPET–PVA aerogel (rPPA), made from freeze-drying, exhibits ultralow ...
