Abstract: A method for estimating the collocation of separated-waste containers was proposed based on the conventional way of calculating waste containers. The method involved two procedures: to determine the theoretical demand of separated-waste containers; and to modify the theoretical demand of waste containers in terms of their configuration and the structure of various communities. The method was applied in Beijing to estimate the demand of separated-waste containers in six typical communities ( schools, residential area, office buildings, shopping centers, government offices, and hotels) at different separation rates. The result shows that for residents area, the configuration is recyclables: kitchen waste: others = 1 ∶1 ∶1 in all the separation rates; for schools, office buildings, shopping centers and government offices, when the separation rate is lower than 50% , the configuration is recyclables∶kitchen waste∶others = 1 ∶0 ∶1, and when the rate is higher than 50% , the proportion is 2 ∶1 ∶1; for hotels, the proportion changed greatly. The collocation number increases with the separation rate in schools, office buildings, shopping centers and government offices, while the changes in residents area and hotels are small.

摘要： 在传统垃圾桶计算方法的基础上, 提出了分类垃圾桶的配置方法, 其中包括垃圾桶配置比例的判别方法、配置比例和小区结构对垃圾桶需求量的修正方法, 并基于北京市的实际数据计算了 6 种典型小区( 学校、居住区、写字楼、商场、事业区、宾馆) 分类垃圾桶在不同分类率条件下的配置数量。结果表明, 居民区在不同分类率下可回收、厨余和其它垃圾桶配置比例均为1 ∶1 ∶1; 学校、写字楼、商场和事业区, 分类率低于 50% 时, 3 种垃圾桶配置比例为1 ∶0 ∶1, 分类率高于50% 时, 配置比例为2 ∶1 ∶1; 宾馆的分类垃圾桶配置比例变化较大。学校、写字楼、商场、事业区的配置量随着分类率的提高而增加, 而居民和宾馆的配置量变化不大。
