.,), our workers will carefully segregate and process them in compliance with the existing environmental laws, rules, and regulations. Our annual processing capacity is estimated to be around 300,000 tons. Our process begins with household and industrial waste being first shipped to storage yards, where the materials are manually classified into several categories of intermediate raw materials. These are then subject to different methods for further process. 1)Printed circuit board (PCB) and Wire (E -material): These are on standby for the subsequent process. 2)Mixed metals: Being to -crushsubstances, these materials contain some valuable metals, including copper, zinc, aluminum, iron and steel, etc. They are then collected at a feeding zone. 54 The recycling of E -materialand mixed metals then unfolds through several stages: a.They will be placed into a vertical compound Crusher (or “big crushing”) to produce crushed materials. b.These crushed materials are then fed into an eddy current separator (or “magnetic sorter”), where the iron scrapes are separated and can be sold to customers. Copper, aluminum, steel, and zinc remain in the mixed metals (second iteration). c.The mixed metals (second iteration) are then processed through a floating separation system (or “floating select”), during which aluminum scraps are collected, leaving copper, steel, and zinc in mixed metals (third iteration). d.The mixed metals (third iteration) are placed into a color sorter (or “selected by color”), where copper is retained while zinc and steel are sorted out. e.The remaining copper crush is then poured into a smelting furnace (or “melting and casting”), producing the copper ingot as the final product, which is then placed in an open -airyard for cooling down. Iron, aluminum, steel, and zinc scraps will undergo a polishing process to remove the oxide layer on the surface before being stored in the warehouse. 3)Plastic and rubber. These materials will be separated by the water separation system (or “cutting machine”) into plastic beads and rubber beads respectively. 4)Disposable waste. These materials have no further use and will be selected by workers and disposed of by incineration. Among them, plastic, rubber, copper ingot, iron scraps, aluminum scraps, steel scraps zinc scraps are the final products that could be sold to customers and used in the manufacturing of goods. Our company has three production sites, detailed on page59, and we expect to set up an additional facility within three years
