During urbanization, we will face with the many problems caused by the construction waste. To increase the recycling ratio of it, we should learn from Europe and America through the following points:
1. The countries, whose recycling ratio of construction waste is high, always pay much attention to the legislation against the environment protection. At the same time, they always strengthen the execution of the law. In China, the legislation against the construction waste starts in the 1990’s, and it is still incomplete compared to that of those developed countries. There are also many shortages in the punishment execution and inspection.
2. The developed countries have elaborate classification to construction waste in terms of source, material, poisonousness and economy. And they have different treatment against different species of construction waste. That’s why their recycling ratio is much higher than ours.
3. The developed countries actively research and promote the updated technology of the construction waste recycle. They have big waste processing production line and have formed a complete industrial chain. And the cost is low. Although China has construction waste plant in every city, but they don’t have good management to those plants, as a consequence the operation cost is much higher than that of those developed countries.
