拆建物料循环再造的发展

由于公众对社会的持续及长久发展日趋关注，循环再造已被香港建造业认同为一项有价值的工序，能把无用的物料转化成有用的制品。本文探讨了拆建物料循环再造的初步构想、引用循环再造的拆建物料的预备工作、推广使用这些产品，以及如何筹建首间试验性循环再造设施。最后提出有关循环再造拆建物料的策略。

Development in Recycling of Construction and Demolition Materials

The local construction industries generate about 14 million tonnes of construction and demolition (C&D) materials every year. Inthe past, the inert part of the C&D materials has been reused as public fill in reclamation projects, which results in land supply for development.However, with the recent raised awareness of sustainable development, recycling is accepted as a valuable process that turns useless materials intouseful products. The inert C&D materials comprise of rocks, sand, mud, slurry, brokenconcrete, and rubble. It could be recycled into aggregate for use as civilengineering construction materials. The construction industry is seekingways to ensure that recycling of C&D material is viable and sustainable. The paper discussed the initiation of the idea of recycling of C&Dmaterial, the preparation for introducing the use of recycling C&D products,the promotion of its use and the establishment of the first pilot recyclingplant. Finally, the paper describes the strategy for recycling of C&Dmaterials.
