STEPS

Recycling Process

The facility functions via a complex and advanced processing system that guarantees effective sorting and retrieval of recyclables while reducing waste residue. The process begins at the point of infeed and pre-sorting stage. Materials are fed onto the conveyor belt uniformly with the help of a drum feeder, avoiding blockages and system overload that could impact the subsequent processing steps. Upon the entry of materials, a splitter screen segregates them on the basis of size and density. Items generally smaller than 3 inches are conveyed towards a particular processing belt whereas the larger materials continue to further sorting. At this stage, a glass breaker screen which is equipped with triple steel discs breaks and separates glass particles, preparing the glass for subsequent refinement. Later the materials move on to the glass cleanup phase, where high precision techniques for material sizing and sorting are applied to eliminate contaminants and obtain a cleanly separated glass fraction. The remaining items move towards the paper recovery section, featuring a combination of sorting screens and quality assurance systems to handle paper and OCC.

Oversized cardboard is separated from other items with the help of 580 OCC screen, enabling quick diversion of bulky paper items. Subsequently, materials are inspected by the QCC quality control system and eliminates any remaining contaminants to achieve high-grade paper recovery. 440 ONP screen sorts smaller fiber items such as newspapers and the 4M sizing sorting screens enhance the sorting precision, getting fibers ready for the next phase of optical sorting. Once the paper is segregated, high precision optical equipment which includes paper cleanup optics and QCC optical systems, detects and remove contaminants, ensuring the presence of quality fibers in the sorting process. Surplus materials are held in temporary mid system bunkers that regulates the flow and guarantees continuous flow into the downstream process. Other materials, such as metal and plastic, then proceed to the container recovery area. An elliptical sorter separates items into two-dimensional (newspaper, office paper), three-dimensional (containers, cans), and fine particles. In order to extract ferrous metals, magnetic units mounted above conveyors are used. Later to recover certain categories of plastics, optical sorters are utilized. PET optical sorting machines identify and extract #1 plastic like bottles where # 2 plastics are segregated by HDPE optical sorters into colored and natural batches. Likewise polypropylene (PP) optical sorters extract #5 plastics. Aluminum cans (non-ferrous metals) are separated through eddy current technology which generates electromagnetic forces to repel these materials. For maintaining accurate outcomes, triple track optical technology enhances the material separation of PP, PET and HDPE plastics, while optical sensors identify and segregate any leftover recoverable materials not captured in the initial stages. These optical systems are supported by compressors by supplying the precise airflow for accurate ejection. Lastly, the segregated materials move towards the balers for final baling and compacting. For compressing materials into densely packed bales, single and two-ram balers are used which enhances the ease of handling and transporting. The single-ram baler is designed for handling large-scale materials quickly, whereas two-ram baler specializes in baling metal and plastic containers. Waste residues which were not recycled are sent to residual compactors where they are compressed for disposal.
