回收的建筑材料是“绿色”运动和资源可持续性的一部分，可减少对垃圾填埋场的拆除碎片的数量，并减少生产新建筑和改建所需的能量量。

今天通常回收的其他建筑材料包括以下内容：
- 混凝土砌体单元，结构混凝土和混凝土路面，它们在新混凝土中被压碎并用作骨料，用于建筑物和道路下的紧凑型填充物。
- 干墙板，石膏和其他材料的石膏，用于重新使用建筑材料，并用作农业的土壤添加剂。
- 沥青路面，被压碎并用作新的沥青路面的骨料，并在道路下进行压缩填充。
- Asphalt shingles, which are processed and used in asphalt pavement.
- 挽救，融化并制造成新材料的金属。
- Plastics of several types, which are re-manufactured into new products.
Although this recycling is often viewed as beginning in the late 20th and early 21st centuries, it is in fact much older, and has been going on for thousands of years.
在公元5世纪后期，罗马帝国倒台之后，罗马市被从中欧，东欧和亚洲迁移的入侵者被解雇了几次，罗马及其建筑物的心脏陷入了失败。在后来的几个世纪中，这些废墟被开采用于大理石，石灰华和其他细小的石头。

Photo 2 shows a wall in the ruins of the Baths of Caracalla in Rome, from which the finely finished cut marble and Travertine were stripped over the centuries and reused in the construction of churches, public buildings, and monuments in the area. Even some of the brick have been stripped from this wall for use in more common construction, leaving the concrete core of the wall exposed, accelerating weathering and deterioration of the remaining structure.

Other examples of the recycling of building materials include the use of the fine limestone facing from the 5,000-year-old pyramids at Giza in Egypt in public buildings in modern Egyptian cities, the use of bricks from 5,000-year-old Sumerian and Babylonian ruins in the Middle East in new construction, the use of marble from 3,000-year-old Greek ruins in more modern buildings, and the use of wood and stone carvings from the bombed-out cities of Europe after World War II in new buildings.
尽管建筑材料的回收已经持续了数千年，但它从未如此大的规模和今天正在发生的科学研究水平。此外，普遍的态度是建筑物不再需要建造才能持久。最初使用后，它们可以被拆除，并将材料重新用于另一个结构。
这方面的一个例子布鲁里溃疡10岁的“大盒子”siness that moves to a newer, bigger big box, leaving its original building vacant. And, after a few years, the vacant building is dismantled, demolished, and at least partially recycled because no one has a use for that building anymore. It is often less expensive to build a new building than to remodel an old one.
