Waste management

The main types of waste managed by URT include household waste and process waste. In recent years, URT has been dedicated to waste reduction and has focused on the following areas
  • It includes promoting household waste reduction (e.g., advocating for the use of eco-friendly utensils like cups and reducing the use of disposable plastics), water conservation, and paperless operations (e.g., electronic signature approval) measures.
  • Reducing waste at the source, URT collaborates with suppliers to design material selection strategies, streamline material packaging, and opt for reusable materials, promoting sustainable design practices.
  • In waste management, active efforts are made to seek waste recycling and reduce incineration. Examples include physical dismantling for reuse and transforming waste into solid recovered fuel (SRF) for energy recovery.

URT responds to the government's promotion by effectively reusing process-generated waste. Qualified treatment facilities are entrusted with the task of recycling and transforming the waste into solid recovered fuel (SRF), thereby reducing greenhouse gas emissions resulting from waste management. This commitment reflects URT's corporate social responsibility policy. In addition, in 2015, the United Nations announced the "2030 Sustainable Development Goals" (SDGs), which include 17 goals such as eradicating poverty, mitigating climate change, and promoting gender equality. URT's efforts to reduce greenhouse gas emissions in waste management align with the SDGs' goals of "responsible consumption and production" and "climate action," as it continues to progress towards sustainable development objectives.

Solid Recovered Fuel (SRF)

To promote the policy of waste fuelization and address the issues of high-calorific waste disposal and the reduction of fossil resources and fuel extraction, the Environmental Protection Agency (EPA) advocates the conversion of waste into "Solid Recovered Fuel" (SRF). SRF is produced by recovering and transforming non-hazardous and combustible materials from waste, such as plastic, biomass (such as waste paper, wood, and other wood fiber waste), into a homogeneous and consistent fuel. SRF can be used in dedicated combustion equipment without the need for coal, oil, or natural gas as fuel. SRF has higher calorific value and efficiency, as well as lower greenhouse gas emissions, making it environmentally beneficial. It provides an opportunity for materials that would otherwise be discarded and non-recyclable to be reused.

The recycling and reuse of waste glass.

Glass is a material that can be fully recycled and reused. It is primarily made from silica sand, is non-toxic, and can be recycled. After undergoing processes such as sorting, cleaning, crushing, screening, and remelting, it can be transformed into various products. Taiwan has the second-highest glass recycling rate globally, following Sweden. The uses of recycled glass are as follows :

  • Crushed glass can be mixed with asphalt to create road surfaces, enhancing their strength and friction coefficient. Additionally, glass sand asphalt surfaces provide excellent reflection, serving as a visual warning to drivers during nighttime travel while also offering an aesthetically pleasing appearance.
  • The crushed glass can be mixed with construction materials to create green building materials such as floor tiles, ceramic tiles, and construction bricks.
  • The crushed glass, after the crushing process, can be used as reflective sheet materials and can be recycled to create artistic crafts and accessories for clothing.
  • The recycled glass, after undergoing processing, can be melted in furnaces to manufacture glass containers, glass fibers, and other glass products.
Physical dismantling for reuse.

Waste undergoes sorting, crushing, and purification to extract reusable materials, which are then transformed into recycled products. The following types of waste are included :

    • Waste printed circuit boards (PCBs) and their scraps can be decomposed, crushed, and sorted to produce reusable materials such as glass fibers and metal powders. These materials can then be further modified and transformed into recycled products. For example, modified glass fibers can be used as "concrete admixtures" in the production of concrete.
    • Waste lighting sources, after undergoing decomposition, crushing, purification, and sorting, yield usable materials such as pure mercury and glass powder.
