The paper is much improved on the previous version. The flow of the paper is much better and the content more cohesive. I just have a few minor suggestions:
In the abstract, it is noted that 124,000 tonnes of waste would be created and 66,000 tonnes would be unrecyclable contaminated plastic waste. Is the remainder recyclable uncontaminated waste? Please can you explain what this portion is composed of.
The text in the section on European Standards refers to ‘community face masks’ and ‘Community Face Coverings’. Table 1 refers to ‘Community Masks’. Are these the same thing? Could you please clarify? It would also be useful to explain what is meant by community mask.
The footnote in Table 1 isn’t clear, particularly from ‘but these masks…’ onwards. Please rephrase.
What are the ‘wash bags’ referred to in the section on Materials and their Filtration Efficiency?
In the Cost Comparison Section under Disposal, the text refers to the weight of a single-use mask. Strictly speaking, this is mass.
Is there a better way to present the information in Figure 3? The washing and disposal categories are difficult to make out on the graph.
Could you please check the data in Figure 4? The Republic of Ireland is highlighted in yellow, but I don’t think this is the case. It’s also not clear what is meant by ‘yellow indicates countries where mandatory mask use is imposed on part of the country only but their use is recommended by government’. Do you mean that their use country-wide is recommended but not mandated by government?
There is a sentence in the Discussion and Conclusions section that states that ‘anecdotal evidence in the UK suggests that very few people wear their reusable masks every day’. It’s not clear what this sentence is meant to tell us and I suggest deleting it. People mightn’t wear their reusable mask every day for a variety of reasons, like not going anywhere that requires mask use or wearing a disposable mask instead. It doesn’t necessarily mean that they’re not following the guidelines.
Further on in the discussion, the text states that ‘governments may consider stockpiling masks…’. Is this referring to single-use masks? In the last paragraph, the text uses the phrase ‘capacity capable’ – is this the correct phrase?
There are a few minor grammatical errors throughout the paper. Please give the paper one final proof-read.
