　　The system is controlled from a board fixed next to the chute door. The board has a button foreach class of recycling materials (as well as for unrecyclables). At the press of a button, amicrocomputer locks all other floors' chute door and sets the recycling container turning untilthe right box comes under the chute. The computer also counts the loads and gives a signal byphone when the box is full. And a particular piece of equipment breaks up the nonrecyclables.

　　Sorting(分类) recyclables before they are collected saves the use of expensive materialsrecovery equipment which otherwise has to do the sorting. Such equipment often makesrecycled materials very expensive, so expensive that tons of recyclables remain wasted. Shantzisbelieves his system could help recycled materials become more cost-effective.
