固废处置能力不足

我国煤电、化工等产业快速发展,由此产生的工业固废种类多、存量大,环境压力随之加大。生态环境部公布的《2019年全国大、中城市固体废物污染环境防治年报》显示,全国200个大、中城市一般工业固废产生量达到15.5亿吨,其中综合利用量占处置总量的41.7%。也就是说,每年仍有半数以上的工业固废采取贮存、填埋等方式。工信部节能与综合利用司相关人士表示,京津冀及周边地区煤电、化工等重化工业集聚,工业固废和废旧物资产生量大。2017年,该区域一般工业固废产生量约为13.7亿吨,占全国工业固废产生量的41%,近三年累计利用量约为22亿吨。因其综合利用潜力大、产业互补性强,协同处置成为提升资源利用效率的重要手段。“当前,京津冀及周边地区正处于实现工业绿色发展的攻坚阶段,资源综合利用产业面临着重要历史机遇。但产业发展不平衡、区域协同不充分,产业集中度有待进一步提高,综合利用项目同质化等问题仍普遍存在。”上述人士称。E20环境平台固废产业研究中心负责人潘功告诉记者,因处置能力受限,多地还普遍面临存量压力。一个地区的处置能力,理论上说应与当地工业结构相吻合,但实际却存在供需不匹配、处置效率低、利用低值化等突出问题。“按照生产者责任制,谁污染、谁治理,最理想的方式是由生产企业自行处置。然而,出于成本、技术等因素,产废企业处理手段单一,仅靠自身往往难以高效处置。选择先整合再处置,通过区域协同、产业协同,资源回用效率更高、价值更大。”

低效、低值的处置方式亟待扭转
