Solid Waste Is Not “Waste” – How Construction Debris Gets a Second Life
随着城市化进程加速，旧建筑拆除与新建工程并举，产生了大量的建筑废渣与工程弃土。这些看似无用的“废料”，实则蕴含丰富可回收资源，而传统处理方式如露天堆放、简易填埋，不仅占用土地，更浪费了其中可观的资源。另一方面，砂石等天然矿产资源日益紧缺。因此，推动建筑固废的资源化再生利用，对于节约自然资源、建设资源节约与环境友好型社会至关重要。
Rapid urbanization is tearing down old buildings and throwing up new ones, churning out mountains of broken concrete and excavated soil. What looks like worthless rubble is actually a concentrated store of reusable material; yet the habit of dumping or shallow-burying it wastes both land and resources while natural sand and gravel supplies keep shrinking. Turning this debris into new resources is therefore vital for conserving raw materials and building a conservation-minded, eco-friendly society.
建筑固废如何实现再利用
How Construction Debris Gets a Second Life
目前，建筑固废可通过多元化路径实现高价值再利用，真正践行“固废不‘废’”的理念，具体路径如下：
Today,construction solid waste can be repurposed through diversified pathways to achieve high-value reuse, truly putting into practice the concept of "solid waste is not waste." The specific pathways are as follows:
1.应用于路基填料| Sub-grade fill
建筑固废经过专业破碎、筛分、碾压等工艺处理后，可作为优质的回填材料，用于道路路基、广场地基等工程的填筑，或进一步加工成商品混凝土骨料，供应给混凝土搅拌站及预拌砂浆站。
After crushing, screening and compacting, the processed material becomes premium backfill for roadbeds, plaza foundations, etc., or is further refined into graded aggregate sold to ready-mix or mortar plants.

2. 应用于再生混凝土制品|
Recycled concrete products
这是建筑固废“变废为宝”的精深加工方向，通过多环节处理实现价值升级，全程闭环可控：
初步分选：将混杂的建筑垃圾进行分级筛分，分离出的黄土可直接作为园林绿化、土方回填，实现初级资源回收。
核心资源化：将分选出的砖、石、混凝土块等，通过破碎设备加工成不同粒径的再生粗细骨料，可匹配天然砂石，满足各类建筑制品需求。
This is the high-end route—an upgrade from rubble to finished goods within a fully closed, controllable loop:
- Pre-sorting: mixed construction waste is classified; sifted loam goes straight to landscaping or earth backfill for an instant first-round recovery.
- Core recycling: separated brick, stone and concrete are crushed into certified coarse and fine aggregates that match natural sand and stone for any building product.
3. 成品制造-砌块制品|
Product manufacture-Block products
成品制造：这些再生骨料可替代天然砂石，通过砖机设备生产出各种混凝土制品，如标砖、空心砌块、植草砖、连锁铺路砖、水利护坡砖等，重新回归建筑市场。
Product manufacture: those aggregates replace virgin material in block machines that turn out standard bricks, hollow blocks, grass pavers, interlocking pavers, hydraulic slope-protection blocks and more—ready to re-enter the market.
