Since many years, companies are trying to cope with impressive technological growth rates, severe environmental issues and even more restrictive national and international directives. However, innovative Business Models (BMs) and industrial strategies adequate to this new context are still either under development or implementation. To this aim, the article proposes a systematic literature review on existing Circular Business Models (CBMs) and their classification methods, by selecting the most promising ones. A total amount of 283 articles related with CBMs has been assessed into detail, by identifying: 5 archetypes, 9 classification methods, 5 adoption-oriented challenges, 4 decision-support tools and 3 additional research areas. Key findings demonstrate that: i) Product-Service Systems (PSSs)-oriented and Reuse, Remanufacturing and Recycling (3R)-based CBMs are the most common archetypes, ii) Business Model Canvas is the most diffused classification framework, iii) sustainability and company-based challenges are the most discussed by the experts and iv) sustainability check-oriented is the most common type of decision-support tools. These (and others) results could support both companies, researchers and governments in updating the current knowledge on CBMs and make them adoptable for practitioners from different industrial contexts.

多年来，公司一直在努力应对令人印象深刻的技术增长率，严重的环境问题以及更加严格的国家和国际指令。但是，仍在开发或实施适合这种新情况的创新业务模型（BMs）和产业策略。为此，本文通过选择最有前途的文献，对现有的循环商业模型（CBM）及其分类方法提出了系统的文献综述。通过确定：5种原型，9种分类方法，5种面向采用的挑战，4种决策支持工具和3个其他研究领域，对与CBM相关的283篇文章进行了详细评估。主要发现表明：i）面向产品服务系统（PSS）和重用，基于再制造和回收（3R）的CBM是最常见的原型，ii）业务模型Canvas是最分散的分类框架，iii）专家们讨论最多的是可持续性和基于公司的挑战，并且iv）面向可持续性检查的是最常见的决策支持工具类型。这些（和其他）结果可以支持公司，研究人员和政府双方更新有关煤层气的最新知识，并使它们适用于来自不同行业背景的从业人员。
