Abstract
The global population’s continuous growth leads to an escalating production of solid waste. This presents significant challenges, especially in urbanized areas like Zurich. The city’s existing infrastructure incorporates recyclable waste collection sites, which are strategically positioned throughout the municipality. Specific workers from the responsible institution manually maintain these sites. This task, which is already physically demanding, is further intensified by the illegal dumping of waste and bulky items by the residents. Despite having vehicles designed for the collection of smaller waste, these workers are often forced to manage large, cumbersome items without appropriate equipment. The severity of the resulting strain is challenging to assess, even though the workers have already reported physical complaints. Therefore, this thesis aims to quantify the strain levels associated with the current activities of the affected individuals. Furthermore, another goal is to develop a technical aid in the form of a concept, specifically tailored to the workers to reduce the physical burden of loading bulky items. To achieve these objectives, scientifically recognized ergonomic risk assessment methods were employed, original studies were conducted in collaboration with the workers, and an adapted development process was implemented. Based on the findings, it was evident that the workers are subjected to significantly increased strain levels, leading to elevated risks of both injuries and chronic illnesses. The handling of bulky items significantly contributed to this strain, but so did the activities related to the management of smaller waste. The development process led to the creation of a suitable design concept that effectively meets the diverse needs of the workers. This design facilitates the loading of bulky items into the vehicle without any intervention from the workers. When compared to existing technical products in the market, the developed concept proved to be the most optimal for the given working environment. This research yielded various insights to formulate actionable recommendations and strategies to improve the workers’ health and working conditions in the future. It is also advised to implement these recommendations immediately. Moreover, it is crucial to realize the developed design to evaluate its efficacy in reducing physical strain on workers. Show more
