All too often, waste authorities either assume that they know enough about their bulky waste stream or that it is too insignificant to deserve attention. In this paper, we use Hong Kong as an example to illustrate that official bulky waste figures can actually be very different from the reality and therefore important waste management decisions made based on such statistics may be wrong too. This study is also the first attempt in Hong Kong to outline the composition of bulky waste. It was found that about 342tonnes/day of wood waste were omitted by official statistics owing to incomplete records on actual bulky waste flow. This is more than enough to provide all the feedstock needed for one regular-sized wood waste recycling facility in Hong Kong. In addition, the proportion of bulky waste in the municipal solid waste (MSW) streams in Hong Kong should be about 6.1% instead of the officially stated 1.43%. Admittedly, there are limitations with this study. Yet, present findings are suggestive of significant MSW data distortion in Hong Kong.
垃圾管理当局往往要么自以为是地认为他们对大件垃圾有足够的了解，要么认为其微不足道而不值得关注。本文以香港为例，说明官方大件垃圾数据实际上可能与实际情况大相径庭，因此基于此类统计数据做出的重要废物管理决策也可能是错误的。这项研究也是香港首次尝试概述大件垃圾的构成。研究发现，由于对实际大件垃圾流量的记录不完整，官方统计数据遗漏了约 342 吨/天的木材废物。这足以提供香港一个常规规模的木材废物回收设施所需的全部原料。此外，香港城市固体废物（MSW）流中的大件废物比例应为 6.1%左右，而不是官方公布的 1.43%。诚然，这项研究存在局限性。然而，目前的研究结果表明香港的 MSW 数据存在明显的扭曲。
