The article presents a complete approach for the wood industry for assessing the state of circular economy adoption by companies. A methodology for achieving this purpose is proposed and then implemented with the help of a specific questionnaire. The study is based on a literature survey with two components, one relating to reports on the concept of circularity and one relating to the methodological aspects of determining and measuring the progress of companies. Starting from these aspects and factoring in the sectoral evolution in Romania, the assessment directions and detailed questions for each are established essentially through a mind-mapping process. For validation, the questionnaire with seven evaluation viewpoints covered in 28 items is applied within the Romanian wood industry to 60 companies. The analysis of results is carried out using descriptive and inferential statical methods, such as ANOVA, showing good progress of the industry at company level, through individual efforts as well as the need to continue the transformation of the sector from the point of view of regulatory oversight and market acceptance. A set of recommendations for companies to advance their situation is proposed to help the maturation of the current circular approaches.
