To achieve sustainable development, supply chain management needs to be related to sustainable business practices, which include relevant values and sustainable purchasing policies. Focusing on these principles on the topic of coffee, this study shows the difficulties associated with this product. The study finds that coffee production is dependent on factors unrelated to management. This paper presents a case study of Delta Caf\u00e9s owned by Grupo Nabeiro, a Portuguese company that shows relevant ways of achieving sustainable business methods to be incorporated in supply chain management. Our research shows a business based on sustainable, efficient handling of the food safety of its product and certification along the supply chain, as well as an adaptable purchasing policy. By reviewing the literature and information provided by the company, we confirm that the case study is a business leader in innovation, thought process, and action related to sustainability practices. Our research illustrates how business operations and culture can be explored to achieve sustainable buying processes and practices.<\/jats:p>","DOI":"10.3390\/su14010459","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T23:08:26Z","timestamp":1641769706000},"page":"459","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Sustainability in the Coffee Supply Chain and Purchasing Policies: A Case Study Research"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3794-901X","authenticated-orcid":false,"given":"Jo\u00e3o F.","family":"Proen\u00e7a","sequence":"first","affiliation":[{"name":"Advance\/CSG, ISEG, University of Lisbon, 1200-109 Lisbon, Portugal"},{"name":"Faculty of Economics, University of Porto, 4200-464 Porto, Portugal"}]},{"given":"Ana Cl\u00e1udia","family":"Torres","sequence":"additional","affiliation":[{"name":"Faculty of Economics, University of Porto, 4200-464 Porto, Portugal"}]},{"given":"Bernardo","family":"Marta","sequence":"additional","affiliation":[{"name":"Faculty of Economics, University of Porto, 4200-464 Porto, Portugal"}]},{"given":"D\u00e9bora Santos","family":"Silva","sequence":"additional","affiliation":[{"name":"Faculty of Economics, University of Porto, 4200-464 Porto, Portugal"}]},{"given":"Grazielle","family":"Fuly","sequence":"additional","affiliation":[{"name":"Faculty of Economics, University of Porto, 4200-464 Porto, Portugal"}]},{"given":"Helena Lopes","family":"Pinto","sequence":"additional","affiliation":[{"name":"Faculty of Economics, University of Porto, 4200-464 Porto, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bratt, C., Sroufe, R., and Broman, G.
