Miami’s Mark Shanties has made it simple for those living in tall buildings to use the chute and recycle too. In Shanties Hi-Rise Recycling System， a chute leads to a pie-shaped container with six boxes that can turn around when operated. The system， which fits in the same space as the chute and container now in use， enables glass， plastic， paper， metal， and other rubbish to go into separate boxes. The system is controlled from a board fixed next to the chute door. The board has a button for each class of recycling materials（as well as for unrecyclable）. At the press of a button， a microcomputer locks all other floors chute door and sets the recycling container turning until the right box comes under the chute. The computer also counts the loads and gives a signal by phone when the box is full. And a particular piece of equipment breaks up the no recyclables. Sorting[分类] recyclables before they are collected saves the use of expensive materials recovery equipment which otherwise has to do the sorting. Such equipment often makes recycled materials very expensive， so expensive that tons of recyclables remain wasted. Shanties believes his system could help recycled materials become more cost-effective.
