TAIPEI (Taiwan News) — Taiwan faces widespread illegal soil dumping as regulatory gaps, weak enforcement, and the lure of lower costs create opportunities for construction-waste operators, per Business Today.
In August, the Miaoli District Prosecutors Office indicted 49 people in the county’s largest illegal dumping case to date. Authorities said the group earned nearly NT$300 million (US$9.85 million) by dumping construction waste across a site in Houlong Township, covering an area about the size of five football fields and piling waste up to the height of a 10-story building. The operation involved a network of soil haulers, unlicensed trucking companies, and unregulated waste processors.
Transporters in the Miaoli case allegedly used forged manifests to simulate legal disposal. Soil treatment sites reportedly colluded by stamping falsified documents, while no agency cross-checked the data.
Between 2016 and March 2024, Taiwan recorded 5,859 illegal soil dumping cases, according to the National Land Management Agency. Officials attribute the condition to inconsistent local oversight and a lack of clear regulatory authority.
The volume of surplus construction soil has sharply increased, reaching 44.81 million cubic meters in 2023 — double the amount recorded in 2016. Legal disposal can cost up to NT$4,500 per cubic meter, while illegal dumping costs as little as NT$800. The significant price gap has led some operators to bypass legal channels.
The NLMA says Taiwan primarily relies on two channels to reuse surplus soil: soil exchange and licensed soil processing sites. However, not all material is successfully matched to end users, and gaps in tracking still allow some flows to go unaccounted for.
Uneven enforcement further complicates management. Some local governments require GPS tracking of dump trucks and use electronic manifests to monitor flows, but adoption and documentation standards vary, making verification difficult for field inspectors.
In March, the Control Yuan faulted the interior ministry for failing to implement a dedicated law for surplus construction soil, resulting in unclear responsibilities and inconsistent enforcement. In response, the Ministry of Environment has proposed stricter penalties under amendments to the Waste Disposal Act, including raising the maximum prison term for serious violations to 10 years and introducing GPS monitoring and anti-asset-evasion measures.
DPP Legislator Kuo Kuo-wen (郭國文) urged the government to mandate GPS tracking, unified documentation, and the creation of a database of violations. Former Environment Deputy Minister Chan Shun-kuei (詹順貴) also called for annual forecasts and controls on soil demand for construction projects.
In response, the interior ministry plans to introduce standardized transport manifests and mandatory GPS requirements by next year. The plan also includes an NT$113 million budget to help local governments develop soil treatment facilities.
