Cost-benefit analysis of reusable takeaway food containers usage: a case on campus in China

Promoting the use of reusable takeaway food container (RTFC) in takeaway industry is an effective way to reduce the negative environmental impacts caused by single-use plastic containers. This study intended to figure out the barriers to the new business model deployment through evaluating the economic costs and benefits of RTFC from a stakeholder's perspective. Taking the pilot RTFC project at a university in Guangdong province as a case, we established a holistic cost and benefit analysis framework from a stakeholder's perspective. Both the costs and benefits with and without a market price of each stakeholder were evaluated using market price method and contingent valuation method. The analysis result shows that while shifting to reusable takeaway food container, the costs and benefits of all the main stakeholders changed. The net benefit of consumers is positive about 360 thousand yuan during 2020-2025, while the platform company, the university and the restaurants gain negative net benefits ranging from - 20 to - 470 thousand yuan under current operation situation, which may hinder the sustainable development of this new business model. However, the sensitivity analysis shows that all the stakeholders could gain a positive net benefit by adjusting the rental price, cleaning price and packaging price, as well as optimizing the location of recycling cabinets.
