Sammanfattning

This thesis investigates the management of waste oil at Volvo Trucks and evaluates the potential of adopting more sustainable practices, particularly through use of re-refined base oil (RRBO). As sustainability becomes increasingly critical in the automotive industry, the effective handling of waste materials, such as engine oil, is essential for both environmental responsibility and cost effectiveness. The current management practices at Volvo Trucks reveal a significant gap in knowledge regarding the fate of waste oil after collection. Workshops often lack clarity in their contracts with recycling companies and the following processing of the oil. This thesis aims to broaden the understanding of waste oil management practices, regulatory frameworks, and the potential for integrating RRBO into new engine oil formulations. Through surveys and field visits to various workshops across Europe, data was collected on waste oil storage, collection practices, and financial arrangements with recycling companies. The findings indicate a diverse range of practices, with many workshops demonstrating a commitment to proper waste oil management, while others exhibit inconsistencies that could hinder recycling efforts. The analysis highlights the environmental benefits of utilizing RRBO, which can significantly reduce carbon emissions compared to incineration. However, the ability to incorporate RRBO into Volvo's products depends on the practices of oil producers, necessitating further testing and validation. In conclusion, this thesis provides valuable insights into the current state of waste engine oil management at Volvo Trucks and outlines actionable recommendations for enhancing sustainability practices. By standardizing procedures and exploring the integration of RRBO, Volvo can strengthen its commitment to environmental responsibility and improve its market reputation.
