Abstract:
... In this study, we conducted a survey to quantify and assess the generation of wood waste by Ohio’s wood industry cluster. We find that large amounts of wood waste are produced in the state, and that limited markets exist for their use. These findings suggest a potential need for cooperative structures to manage and find markets for sawmills, as well as the need for a recycling facility to handle t ...

Abstract:
... Wood dust produced in medium-density fiberboard (MDF) processing is a major occupational hazard in wood industry and may damage processing equipment. In many wood processing factories, dust collecting systems need to be optimized for the distributional and morphological characteristics of dust in the workshop so that economical and efficient dust control can be achieved. In this study, weighting, ...

Abstract:
... For wood screw connections, the withdrawal capacity is essential and is therefore an optimization target for wood screws. The withdrawal capacity is based on the composite action between the screw thread and the wood. Optimizing thread geometry requires knowledge of how thread parameters influence the withdrawal capacity. Up to now, this knowledge is largely unknown. Therefore, the objective is to ...
