Proper management of different waste streams generated in conjunction with oil Exploration and Production (E&P) activities in Sudan is a major challenge for Petrodar Operating Company (PDOC) inter alia. PDOC generates a range of waste streams that are expected to significantly increase especially during and after the planned expansions. Therefore, there is a growing need for establishing an Integrated Waste Management System (IWMS) through a systematic approach for enhancing the attempts to redirect PDOC’s efforts towards realizing its commitment to best HSE standards. This study introduces the composition of an Integrated Waste Management System (IWMS) that incorporates better strategies and practices that particularly suit the case of PDOC’s Central Processing Facilities (CPF) (Al-Jabalayn site), Sudan in accordance with the Waste Management Hierarchy. In the first part; mainly the qualitative characterization of the past, current and the near-future situation at Al-Jabalayn site in terms of waste management strategies and practices are all described and analyzed, followed by the creation of a “waste inventory”. Accordingly the elements of a recommended set of appropriate waste management strategies and practices are identified in order to form a framework of an Integrated Waste Management System (IWMS) that particularly fits the case of Al-Jabalayn site and its operating circumstances. The model framework that has been suggested based on this case study can be promoted, replicated and applied to similar Sudanese E&P sites; operating under same conditions. The adoption of such an approach shall pave the way to diminish the gap between the current situation and the most possible sustainable waste management system in the sector.

Den svenska regeringen har tagit beslut om en digitaliseringsstrategi, som syftar till hur Sverige kan bli bäst i världen på att dra nytta av digitaliseringens möjligheter. Genom inrättandet av Myndigheten för digital förvaltning (DIGG) ska digitaliseringsstrategin förverkligas och stödja den digitala transformation som kännetecknar svenska myndigheters övergång från e-förvaltning till digital förvaltning. Digitalisering av fastighetsinformation är en del av denna transformation och ett viktigt verktyg för att uppnå effektivare fastighetsförvaltning. Sveriges regioner är en av landets största fastighetsägare och förvaltar miljontals kvadratmeter, trots detta är användningen av digitaliserade fastighetssystem ovanligt låg inom offentlig sektor. Mycket visar på att offentlig sektor lider av en låg digital mognad och har svårigheter att ta till vara på digitaliseringens möjligheter och lyckas med sina projekt. Syftet med denna studie är att undersöka vilka utmaningar som går att identifiera vid implementering av ett IWMS-system inom offentlig fastighetsförvaltning, samt vilken roll systemet har som plattform har vid en sådan implementering. Studien utgörs av en fallstudie med fem semistrukturerade intervjuer som studerar en specifik region på djupet. Utifrån detta har nio kategorier av utmaningar identifierats och analyserats utefter fyra bestämda teman. Studiens resultat påvisar vikten av att förstå innebörden av standardiserade system som plattformar och vilka konsekvenser som det kan innebära. Men även att vikten av att säkerställa fastighetsdata är central vid implementeringen av standardiserade fastighetssystem. / The Swedish government has decided on a digitalization strategy, which aims to how Sweden can be the best in the world to take advantage of the possibilities of digitalization. Through the establishment of Myndigheten för digital förvaltning (DIGG), the digitalization strategy will be realized and support the digital transformation that characterizes the Swedish authorities' transition from e-government to digital management. Digitalization of real estate information is part of this transformation and an important tool for achieving more efficient property management. Sweden's political regions are one of the country's largest property owners and manage millions of square meters, yet the use of digitized real estate systems is unusually low in the public sector. Much indicates that the public sector suffers from a low digital maturity and has difficulties in taking advantage of the possibilities of digitalization and succeed in its projects. The purpose of this study is to investigate the challenges that can be identified in the implementation of an IWMS system in public property management, and what role the system has as a platform in such implementation. The study consists of a case study with five semi-structured interviews that study a specific region in depth. Based on this, nine categories of challenges have been identified and analyzed along four specific themes. The results of the study demonstrate the importance of understanding the meaning of standardized platforms and the consequences it may have. But also, the importance of securing data is central to the implementation of standardized property systems.

Waste can be considered as an urban burden or as a valuable resource depending on how it ismanaged. Different waste treatment technologies are available at present to manage municipal solidwaste (MSW). Various actors are involved to develop waste treatment technology for certain area.The aim of this study is to analyze the driving forces in technical development in waste sector inSweden. The study is also done to identify emerging waste management technology in Sweden.Moreover, a comparative study of existing and emerging technologies is done by Life CycleAssessment (LCA) model. An extensive literature review and pilot questionnaire survey among thewaste management professionals’ is done for the study. LCA model is developed by SimaProsoftware CML2 baseline method is used for identifying environmental burden from the wastetechnologies.Dry composting, Pyrolysis-Gasification (P-G), Plasma-Arc are identified as potential emergingtechnologies for waste management system in Sweden. Technical developments of thesetechnologies are influenced by indigenous people’s behavior, waste characteristics, regulations, healthor environmental impact and global climate change. Comparative LCA model of P-G andIncineration shows that, P-G is a favorable waste treatment technology than Incineration for MSW,especially in acidification, global warming and aquatic eco-toxicity impact categories.
