第一，大量占用耕地，土地浪费严重。目前石角、龙塘两镇从事拆解加工的经营户1300多户，其中专门拆解各类报废进出产品(五金电器、电线电缆等)的经营户约有1000多户。这些经营户大多散落在村镇内、公路边的各个角落，以落后的加工方式进行加工，造成严重的土地资源浪费。
    第二，拆解技术落后，二次污染严重。由于经营户拆解技术落后，个别经营户甚至对细小的电线或者他们认为没有利用价值的材料进行燃烧处理造成空气污染，拆解洗涤产生的废水、废油等未经处理直接排放造成水污染和土壤污染。
    第三，资源浪费严重，再生利用率低。由于经营户分散，加工技术水平落后，对许多仍有回收利用价值的副产品，如电线电缆拆解下来的废塑料、废橡胶、废纸等，因为无法集中回收利用失去其经营价值，最终被随意丢弃或焚烧，资源浪费十分严重。
    第四，分散经营的产业效益差，税收流失严重。清远目前的废旧金属拆解业目前还缺乏规范的交易平台，个体户式的经营加工无法满足利废企业对其供应量和质量的要求，更无法形成合理的产业链。由于加工经营分散，行业指导程度低，直接造成国家税收的损失。
