Waste management

The construction waste generated in the construction process is the main source of waste for RTC. In2023, RTC will improve the management level of industrial waste to achieve the goal of zero waste of industrial waste, formulate the “Implementation Measures for Waste Reduction”, and take “Source Reduction and Classification” and “Resource Recycling” as the main management policies of industrial waste, so as to effectively recycle resources. At the same time, according to the announcement of the Ministry of Environment, the “Administrative Measures for the Review of the Industrial Waste Clean-up Plan”, fill in the industrial waste cleanup plan, and declare the waste clean-up and construction residual earth and rock flow certification documents to ensure compliance with laws and regulations to avoid other impacts on the environment.

The waste that may be generated from construction sites and prefabrication plants includes civilian waste, generally harmless construction waste, and other construction demolition residues. At the beginning of each project, RTC plans the waste generated at each stage of the project, and the plan should be announced after being approved by the construction manager and the project manager, and strengthened publicity and requirements in the construction briefing, agreement organization and closing meeting before entering the site. RTC procurement unit has the responsibility to establish the information of recycling manufacturers and formulate manufacturer contracts for the reference, implementation and use of each construction site project, so as to meet the requirements of the waste reduction implementation measures.

RTC waste value chain diagram

RTC strictly abides by the construction waste management strategy of the Ministry of Environment, actively controls the pollution sources of the construction site, and practices the reduction, classification and recycling of waste. At the same time, we have a good grasp of the waste value chain to ensure that waste is not illegally disposed of, thereby reducing the negative impact on the environment.

RTC waste reduction and transportation operation process

In order to reduce the negative impact of waste on the environment, RTC has formulated a waste reduction and transportation operation process to fully grasp the trend of waste and implement waste management.

Water management

Taiwan is mountainous and has short rivers, which cannot store effective rainfall, and in recent years, due to climate change, the frequency of extreme weather has become more and more frequent, and drought and heavy rain have alternated. As a result, the issue of water resources management is becoming increasingly important in Taiwan, and RTC is well aware of the value of water resources and attaches great importance to the management of water resources. Since 2023, RTChas successively begun to take stock of the water resources use of each operating base, and the main business activities and water use areas are concentrated in the greater Taipei area and Taoyuan area, which are divided into office building water for people’s livelihood and pre-foundry industrial water, and the water source is Taipei Water Supply Office and Taiwan Water Company, and the source is Xindian Creek and Dahan Creek, according to the World Wide Fund for Nature (World Wide Fund). for Natur (WWF) water stress area, RTC water use areas are all from low water stress areas.

Water Conservation Actions

The wastewater of RTC Headquarters Office Building is a general domestic wastewater, which is discharged through the sewage and sewer system legally, and does not cause any negative impact on the surrounding environment and water sources. Yangmei precasting plant is a business wastewater, which needs to control the discharge of sewage in accordance with the Water Pollution Prevention and Control Law, and set up process wastewater treatment facilities to meet the “discharge water standard”. At the beginning of 2023, due to the violation of the Water Pollution Prevention and Control Law by the

operation wastewater flowing into the rainwater ditch in the factory and discharged to the outside of the plant through the runoff wastewater discharge outlet, RTC Research plans to separate the rainwater from the sewage and set up a new centralized treatment plant to treat it to improve water pollution negligence. In addition, in terms of construction sites, the construction wastewater needs to be treated in accordance with the construction site runoff wastewater pollution reduction plan approved by the Environmental Protection Bureau. RTC manages the wastewater generated on the construction site, and treats it at the construction site after collection, or outsources treatment to meet the discharge water standards before discharging.

In 2023, the toilets in the headquarters office building will be replaced with sensor-activated faucets, which is not only more in line with modern facilities, but also can effectively save water and reduce water waste. At the end of the year, the pantry and toilet at the bayberry pre-casting plant were replaced with water-saving faucets, which improved the comfort of the working environment and reduced the consumption of water resources. In the future, RTC will continue to invest in water-saving actions related to water reduction and rainwater recycling in pre-casting plants. Among them, through the establishment and operation of a recycling system, it will be possible to maximize the use of water resources at the construction site, realize the recycling and reuse of water resources, and reduce the dependence on natural water sources.
