Minimering av avfall i produktion av prefabricerade husmoduler
(2019) MIOM01Production Management
- Abstract
- Leaving a sustainable society for our children is considered an arbitrary goal for the environmental work that is currently taking place in Sweden. Today, 140 million tonnes of non-hazardous waste is generated in Sweden, which is unsustainable. 31% of the non-hazardous waste is traced to the construction industry, the mining industry excluded. Today, the waste is an unused resource that is purchased and then disposed of, which results in a direct but also hidden cost. Lean is a philosophy that means to eliminate waste made possible by the circumstances of standardized work. Through a series of tools, the possibility of standardized improvement can help both economic, social and environmental factors.

Today, 140 million tonnes of non-hazardous waste is generated in Sweden, which is unsustainable. 31% of the non-hazardous waste is traced to the construction industry, the mining industry excluded. Today, the waste is an unused resource that is purchased and then disposed of, which results in a direct but also hidden cost. Lean is a philosophy that means to eliminate waste made possible by the circumstances of standardized work. Through a series of tools, the possibility of standardized improvement can help both economic, social and environmental factors.
The company for the study produces house modules in factory that are assembled into multi-dwelling buildings on the construction site. Today, waste of the same weight as 10% of the module arises, something the company wants to adjust. The purpose of this study is thus to map and analyze the waste that arises in the manufacturing plant and then develop a framework for minimizing the waste, but also to assist with an external analysis of the construction industrys waste. The study consists of a literature study with a focus on Lean and construction waste around the world and a case study in the factory.
The result of the study shows that on average, the construction industry in Sweden generates 25-30 kg waste per BTA. However, the waste varies depending on building materials, building technology and type of building. Today, the plant generates 26.4 kg waste per BTA, of which just under 55% of the waste consists of wood (including one-time pallet) and just over 25% consists of plaster. The remaining 20% consists of almost half of combustible waste and the rest are a mixture of plastic, corrugated board, insulation and other. The study includes Eco-mapping, material analysis and flow analysis to be able to trace and understand the origin of the waste with the aim of minimizing it.
To minimize waste, the factory should work with four categories, Purchasing, Management, Design and Production. These categories are affected in the presented framework and by setting requirements and procuring routines at these four points, waste can be reduced systematically. A broader implementation of Lean also helps to reduce waste. The factory has worked with some tools by Lean more than others. Hence, they have missed that the Lean house's strength, that the various tools complement and strengthen each other. An action framework has also been presented where the framework focuses on the measures to be able to drive a long-term improvement work. (Less)
