Start-ups often face different challenges than big or medium companies that have been in the market for a longer time; sustainability is no exception. When it comes to sustainability, the company studied for this thesis, Fieldwork Robotics LTD, prioritizes lead time, price, and quality above all else. This paper addresses how sustainability could be embedded in the company’s requirements at every step of the supply chain and how this could be beneficial in the short, medium, and long term. The data used in this paper was collected over six months in different ways: documents coming from the company, observation of processes, and interviews. This thesis shows that some improvements could be made within the supply chain to have a more sustainable approach; for example, including sustainability as a metric when selecting suppliers could significantly improve the sustainability of the supply chain. The possible implementation of these improvements will be described throughout the thesis. A deeper study on the supplier selection process, using an example from the selection process taken by the company for the 3D printed piece supplier, will be conducted. Finally, some advice and proposals will be presented, including how their implementation could have an impact on the overall sustainability of the supply chain.
