Former investigations aimed to explore expert opinions about project success factors. This study enhances the investigations to student opinions for establishing a more comprehensive view of the critical issues. A harmonious collaboration based on agreed values and methods has been appreciated. The study used a survey among engineering and business students (n=155) about the success factors of product development projects. The goal was to explore their opinions and compare those with expert opinions. The results show that clear goals are considered very important by both groups. Project meetings, cooperation, and other soft factors are recognized as more important by the experts than by the students. The results confirm that the order of the opinions is significantly different. The cluster analysis marked three distinctive patterns of opinions. Improving the performance of the mixed project teams reflected in project success calls for action. Accepting the more professional approach the experienced project team members, the lack of students’ competencies can be designated. Changes must be supported by training activities and rethinking the curricula in the field.","PeriodicalId":50884,"journal":{"name":"Acta Polytechnica Hungarica","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135262546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It can be re-melted and used again and again in new products, making it an environmentally friendly metal and a sustainable material. This makes aluminium an excellent material to meet the needs and challenges of different products. Also, aluminium recycling offers advantages in terms of environmental and economic beneﬁts. Therefore, more aluminium must be collected, sorted, and returned into the economy as new products. Aluminium recycling is the process by which various scrap aluminium can reuse in products after its initial production and involves simply re-melting these scraps. This work provides an overview of the basic aluminium recycling process, using postconsumer scrap in the melting process in few laboratory experiments. Typically, postconsumer aluminium scrap is a mixture of alloys and sometimes even a mixture of metals, the main sources for aluminium scrap being the packaging, technology, construction, and the transport industry. In our experiments, different aluminium scrap sources were considered: mixed packaging aluminium scrap and used beverage can scrap, aluminium from electric cables and aluminium from collected castings. Having in view that the chemical composition is the main challenge in aluminium recycling, mass balance of main aluminium alloying elements is performed. This research provides an overview of the aluminium recycling process, from the scrap upgrading to the melting process.","PeriodicalId":50884,"journal":{"name":"Acta Polytechnica Hungarica","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135263910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
