Main problem: This article is for to the divulgation of ideas and projects implemented (or proposed) in the circular economy. The topic covered is the collection and recycling of waste produced by citizens and small businesses. It is a «CASE STUDY» of concrete projects that have been designed using the method of «possibilist economics», i.e. that new branch of Development Economics devised by A.O. Hirschman (USA) and developed by Luca Meldolesi (EUROPE) with his Italian working group (a group of which I have been an active member since 1986). During the years I spent working as a business economist, I adapted and increased the analysis and operational tools of the possibilist method to the subject of business development and creation, expanding the method with some new operational tools derived from my practical work and the analysis of the different realities in which I worked. This adaptation of ‘possibilism’ to business economics has been particularly useful in helping me find ‘possible’ solutions to complex problems in disadvantaged social and economic contexts. Purpose: The goal of this study is to give a concrete example of how the possibilist method is useful to create work and business in any field of economy. Methods: The article analyses a project of the author and its results. Results and their significance: This adaptation of «possibilism in economy» to business economics is a demonstration of the useful to helping economist to find «possible» solutions to complex problems in disadvantaged social and economic contexts.
