Project for the Construction Material Recycling Technology

英文摘要 To achieve resource recycling and sustainability, and to create an eco-friendly society with zero waste, this project focuses on the development of recycling technologies for four types of construction materials (decorative plaster boards, asbestos products, alkaline solid wastes, and waste refractory materials). These include “Recycling Technology for Inorganic Decorative Boards in Construction”; and “Application Technology of Asbestos Product Waste in the Cement Industry”; and “Carbonation Technology for Alkaline Solid Wastes” ; and “Thermal Insulation Ceramic Material Technology for Waste Refractory Materials”. The “Recycling Technology for Inorganic Decorative Boards in Construction” involves the design of an on-site plaster board classification process, coupled with the development of rapid screening technology. This innovation allows for the effective identification and collection of plaster board types in the field, thereby mitigating the introduction of impurities. The plan encompasses a two-stage sorting procedure, capable of reducing the paper fiber content within plaster to a mere 2%. This, in turn, augments the proportion of recycled plaster from 12% to 30%. Even after undergoing three cycles, the material's strength continues to meet the CNS4458 standards. Regarding the “Application Technology of Asbestos Product Waste in the Cement Industry”, a composite heat treatment method is proposed that combines chemical and low-heat interactive reactions, and establishes a low-temperature and non-hazardous treatment test module, reducing the asbestos content to less than 1%. This development achieves the application with both resource reutilization and environmental friendliness. The “Carbonation Technology for Alkaline Solid Wastes” involves introducing carbon dioxide gas into a carbonation reactor to enhance the carbonation of alkaline solid wastes, ensuring that heavy metal leaching comply environmental standards. This process results the utilization and expansion of application of recycled aggregates. Regarding the “Thermal Insulation Ceramic Material Technology for Waste Refractory Materials”, a purification and refining process were established. The waste refractory powder is regenerated by making hollow ceramic balls and converted into hollow waste refractory filler. This filler could be used in insulating building materials in the future to help keep indoors warm. In summary, the anticipated benefits of future technological implementation can be outlined as follows: (1) By reducing impurities in recycled plaster raw materials and increasing the recycled content, it is estimated that the annual recycling volume of plaster board can be increased by 29,000 metric tons.;(2) Through a low-heat treatment method, approximately 500~1,000 metric tons of asbestos wastes can be treated annually.;(3) Utilizing an accelerated carbonation reactor to enhance the carbonation of source materials is projected to increase the annual application volume of incinerated recycled granular materials by approximately 250,000 metric tons.;(4) Effective recovery of refractory waste from incineration plants is estimated to handle 100 metric tons per year, resulting in reduced disposal costs for waste materials.
