Designing a Machine for Picking Up Litter Along Minnesota HighwaysStatus: CompleteReport Date: 07/17/2008 Summary: Collecting trash by hand along highway shoulders and medians in the Twin Cities metropolitan area costs about $2 million per year, is time-consuming and presents serious safety hazards for MnDOT workers. Investigators designed a prototype "trash harvester" for picking up litter in grassy areas. While this prototype did not perform to MnDOT expectations and will not be commercialized at this time, it provides a starting point for further research, design and testing.
