1. Chitin is an important reclaimable resource. 甲壳素是一种重要的再生资源。
2. Therefore, designs reclaimable wedge bolt which can reduce the cost, avoid false construction and increase the recovery. 因此，设计了可回收楔式锚杆，降低了费用，避免了假性施工，提高了回收率。
3. The taper rod of the reclaimable taper anchor can be reclaimed for reuse, thus a large amount of steel can be saved, and construction cost is reduced. 本实用新型的锥杆可以回收再使用，因此可以节省大量钢材，降低工程造价。
4. Blast furnace gas can be used in boiler as reclaimable energy, but boiler which completely burning blast furnace gas has the problem of burning instability. 高炉煤气作为二次能源用于锅炉，存在着燃烧不稳定等问题。
