Case Study on Secondary Building Materials for a Greener Economy
Round 1
Reviewer 1 Report
Dear authors
Please see my comments attached.
---
Topic: Secondary building materials for a greener economy
Manuscript ID: Applied Sciences
The research investigates the suitability of three resources of secondary building materials. The research is based on the technical experiments that are sufficiently explained. There are minor issues that I’d like authors to consider in the second iteration
§ The work needs to undergo moderate proofreading to ensure there is no issues. Lines that need further editing:
§ Line 20: Gtons
§ Line 21-22: maybe building and construction industry to cover infrastructure projects
§ Line 23: needs reference
§ Line 33: use C&D waste only
§ Line 35: Mtons (and in other lines) & the entire sentence
§ Line 53: municipal solid waste (MSW)
§ Line 76: can the recycled materials be described as smart material?
Abstract: pls write about the research implications
Title: it needs better rewording to reflect the research activities/scope, perhaps using an action verb can help
§ Please provide further information on circular economy in German context
§ Better to visualise the sources for secondary building materials in a figure
§ Instead of recycled materials can authors use products with recycled content (PwRC)
§ Please use a table in the introduction to summarise the characteristics of the sources of secondary building materials
§ Pls use some studies that highlight the role of technological advancements/product development etc (in line with this research) in effective C&D waste management to better justify the research objectives. Some can be found below:
A. An investigation into challenges and opportunities in the Australian construction and demolition waste management system. Engineering, Construction and Architectural Management. 29(10): 4313-4330.
B. Using recycled construction and demolition waste products: A review of stakeholders' perceptions, decisions, and motivations. Recycling. 5(4): 31
C. Analysis of factors influencing the creation and stimulation of the Australian market for recycled construction and demolition waste products. Sustainable Production and Consumption. 34(2022): 163-176
§ The first section of Materials and Methods needs to describe the research methods/design
§ Source of figures should be indicated
§ Better to provide subheadings under Discussion
§ Conclusions section is missing, this section should show future research direction, study contribution to theory and practice of waste recycling, limitations of the research and the key findings.
The English has to be proofread before publication

Reviewer 2 Report
Dear Authors, after read your manuscript I have some remarks:
Also, note that there is no conclusion in the manuscript!
I recommend that the title of the manuscript state that it is Case Study.
In the introduction (at the beginning), it is necessary to write a comparative analysis of the qualitative composition of waste not only in Germany, but also in other countries. Also, the purpose of the work is not written in the introduction. The authors wrote only what they presented in their work.
The literature review does not cover the analysis of existing technical solutions for the disposal/reuse of such waste. In its current form, the introduction looks like a report.
With regards
Unfortunately, I cannot professionally assess the level of English
