To promote appropriate management and reuse of industrial waste, the Ministry of Environment (MOENV) amended the Waste Disposal Act on October 24, 2001. Article 39 of the Act stipulates that the reuse of industrial waste shall be conducted in accordance with the regulations of the central competent authorities. According to the regulations of each central competent authority, the reuse methods of industrial waste are divided into three categories: on-site reuse, reuse by announcement/annex, and reuse by permit.
To protect human health and environmental safety and achieve optimal benefits from reused waste, there should be acceptable standards for reusable waste. Common acceptable standards include non-hazardous industrial waste, metal ion concentrations, moisture and impurity content, volatile solid content, pH value, and so on.
Reused products derived from industrial waste should have established quality standards. According to the Regulations Governing the Recycling and Reuse of Industrial Waste, regular testing of the quality of reused products should be conducted. In order to prevent the improper use of reusable products that may pollute the environment or damage human health, management systems such as process tracking and environmental monitoring are used to understand the impact of reusable products on environmental quality. The "Waste Disposal Act" was revised and promulgated on January 18, 2017, and Article 39-1 was added to stipulate the requirements for tracking the flow of reused products. It marks 6 reused items: coal slag, waste foundry sand, electric arc furnace slag, induction furnace slag, cupola slag, waste sandblasting as industrial wastes require waste reuse permits, and shall monitor the movement of its going. If the waste reuse has potential impact on the environment, the competent authority Environmental monitoring should be implemented to prevent environmental pollution.
Taiwan released the "Directions for Resource Recycling Network Waste Cleanup Plans Reviewing Operation" on November 8, 2011. Under a current linear model of waste output, removal, and treatment (reuse), it can upscale an innovative mechanism for the resources circular network. Considering the process life cycle, from raw materials to waste, will encourage maximum resource circulation and assist businesses in jointly proposing "Resource Recycling Network Waste Cleanup Plans" to integrate industries from upstream, midstream, and downstream businesses, containing raw material supply, product use, and waste treatment (reuse). It can cross regions and industries, connect numerous high-tech manufacturers, transform waste into raw materials, reduce the industrial waste environmental impact, and gradually realize a "Resource Recycling Network Virtual Park", moving towards net zero emissions (Figure 1).
