The Group collects reagents for disposal from educational and research institutions.They are packed one by one for collection after confirming that they are stored in proper collection containers. Chemical content analysis is performed for any unidentified (poorly labeled) reagents to determine the appropriate processing method before disposal. Even small quantities of miscellaneous waste that are difficult to handle are also processed properly.
Waste oil and sludge
Based on analysis results, waste oils from factories are mixed and adjusted to achieve the optimal composition, before being recycled as alternative fuels. Meanwhile, sludge is recycled as raw materials for cement after adjusting content and moisture and then kneading them. The aim is to ensure and maintain the quality of all recycled materials.
We collect infectious waste and other waste materials generated by medical institutions. The collected medical waste is incinerated at our plant, and the waste residue is finally disposed of at a controlled final disposal site.
Fire-proof bricks are used as refractories to line glass furnaces, kilns and incinerators.
Waste bricks generated by the demolishing of such facilities and periodic repair work are collected and carefully sorted. Recyclable items are reused as paving materials and fire-proof bricks.
Waste acids, alkalis and sludge (inorganic/organic)
Waste acids, alkalis, and sludge are generated by a wide range of industries, and their properties are diverse, including inorganic and organic. Liquid waste is collected by a vacuum truck, subjected to neutralization and dewatering processes, then treated with microbes, before being discharged into the public sewer system. The residual sludge is recycled as a raw material for refi ning or composting, etc.
Processes of Industrial Waste Disposal and Recycling
We have a system for swift and proper waste disposal based on the necessary licenses for collection, transportation, and intermediate treatment of most types of industrial waste and specially controlled industrial waste. In addition, our outstanding technology for detoxifying industrial waste offers optimal solutions for environmental preservation.
