Review: Addressing climate change mitigation: Implications for the sustainable alternatives to plastics — R1/PR7
Summary
This peer review document evaluates a study examining sustainable alternatives to plastics in the context of climate change mitigation, with the reviewer assessing the paper's treatment of how increasing plastic pollution, accelerated by COVID-19 pandemic-related plastic use, intersects with climate change and whether proposed alternatives are adequately analyzed.
Accumulation of plastic waste is a global issue, and plastic particles are detected in different environments. The recent COVID-19 pandemic has been attributed to significant piling up of plastic waste and debris (including micro- and nano-sized plastic particles), yet the manufacturing of plastic products is still expected to grow. With the continuation of the COVID-19 pandemic, the use and disposal of plastics has resulted in increasing plastic pollution. There has been a lack of research into the effects of climate change on microplastics and, likewise, the effects of microplastics on climate change. This article aims to examine the pros and cons of sustainable alternatives to plastics in addressing the climate change issue. Special attention is devoted to the correlation between climate change and microplastic pollution. This perspective also serves to spawn ideas for mitigating greenhouse gas emissions caused by plastics by identifying the life cycle stages of plastic production.
