These two papers many provide you some useful insights:

Chen, Y. T. (2016). "A Cost Analysis of Food Waste Composting in Taiwan." Sustainability 8(11).

Islam, K. M. N. and M. Jashimuddin (2017). "Reliability and economic analysis of moving towards wastes to energy recovery based waste less sustainable society in Bangladesh: The caseof commercial capital city Chittagong." Sustainable Cities and Society 29: 118-129.

You can make a feasibility study about the solid waste which used  in composting for example, and calculate the cost benefit ratio.

Dear Anwesha

Thank you for your response. I read the recommended papers. The first one was gave me some ideas for my research, but I want the papers which were conducted in the  context of recyclable fractions of municipal solid waste such as PET, glass, metals, and etc.

Once again thank you for your response.

Wish you all the best

Dear Masnat

Thanks for your response. The feasibility study covered not the economic aspects of the projects, it also covered technological, legal and scheduling factors. The goal of a feasibility study is to place emphasis on potential problems that could occur if a project is pursued and determine if, after all significant factors are considered, the project should be pursued. But in our study, the goal is not the feasibility study of implementation of a system.

Once again thank you for your response.

Wish you all the best

It will be more useful when you combined with economics and behavioral analysis it takes care both demand and supply chain. It will be a more holistic way. think of it, and all the best. 

I found the Business Model Canvas was useful in understanding the costs and revenues in the context of who are the customers and what is the offer. 

Dear Dr. Kumar

Thank you so much for your response. The goal of our study was not the investigation of the behavioral or social analysis, but I think the subject which you mentioned is interesting.

Once again thank you for your intellectual helping.

Wish you all the best

Dear Carol

I want to appreciate you so much for your response. I searched about your proposed model and found that it is a strategic management and lean startup template for developing new or documenting existing business models. Is there any experiences in the context of recycling?

Once again thank you for your intellectual helping.

Wish you all the best in your research

Since there are several Techniques used for Solid Waste Management in Different Urban Centers I would suggest you use the "THE WILLING ESS TO PAY OR ACCEPT". You can also NPV to estimat the potential for different Solid Waste Management  systems. I know some one who has been involved in such kind of Research works. I will ask her and come back to you.

Best regards.

Dear Mr. Nyamoga

Thank you for your prompt response and your guidance.

Dear Ata, 

You can consider using "Life Cycle Cost" analysis. There are also plenty of software to carry out the analysis, you can try out OpenLCA, SimaPro, or Gabi, They are mainly to conduct life cycle assessment, but these software can also calculate life cycle cost. 

Hope it helps.

Cheers,

Jimmy

Dear Jimmy

I want to appreciate you so much for your prompt response. You gave me a great idea for my research.I searched about your proposed analysis (Life Cycle Cost), it was amazing, and I think it could be helpful for my work.

Wish you all the best

Ata

Dear Ata,

You are most welcome. I myself am conducting a case study involving life cycle assessment. Hopefully it will one day be my first publication! 

Good luck with your work Sir.

Best,

Jimmy

Dear Jimmy

I assure that you will publish a greate paper at the end.

Wish you all the best

Sorry. I can´t contribute to your investigation. I don´t investigate this issue.

I believe that this relationship can only occur when there is in fact a selective collection in which it is possible to make a proper separation of the waste. With the correct separation of materials and their quantification it may be possible to perform a real calculation under the economic aspect (by type of material) and mainly of the environmental impact that is no longer generated.

Dear Virgilio

Thanks for your response and your contribution, but as I said in my question the goal of our study was not the investigation of proper segregation of solid waste. Our study was performed in a processing facility which received the municipal solid waste generated in a Megacity. We are working on a cost/benefit analysis of the potential of the recycling in the various conditions...
