%T What a Waste - Approaching Hamburg’s Domestic Plastic Waste from a Circular Economy Perspective %L theses_frw2716 %A J.K. Brinkmann %X Germany’s waste management is one of the world’s leading systems. Despite its high standards and numerous regulations, plastic waste is only marginally reintroduced into the economic system. A concept which is discussed as a solution to this is the circular economy (CE) concept. CE envisions an economic model based on the principles of reducing, reusing, and recycling in which waste is not disposed, but reintroduced as resource for new products. Following the CE idea means decreasing the general amount of plastic waste while increasing the reuse and recycling of the remaining amount of plastic waste. Combined with the transition management (TM) concept to steer the change from the status quo to one incorporating the CE idea, this thesis investigates how an approach of decreasing the general and increasing the remaining amount of waste can be fostered in the context of Hamburg narrowed down to the domestic plastic waste fraction. %D 2018
