Track Trash Disposal / Events trash disposal

There are more and more events or night markets held in Taiwan. However, after the event, the place is always a mess and takes a lot of time to clean.
There are two main reason why people cannot throw trash in to the trash can. firstly, the trash cans are not big enough for massive amounts of trash. secondly, people cannot find trash cans or there are too far from them.
The track trash disposal is like Lego, so it can be adjusted the length depending on the size of the place, and a special board moving on the track collects the trash into the bag, which makes collecting trash more efficiently and convenient.
