During moving, home renovation, or office upgrades, used furniture like bed frames, sofas, bookcases, and office desks/chairs often becomes a troublesome “burden”—they are large, structurally complex, hard to disassemble, costly to transport, and random discarding or landfilling wastes land and harms the environment. Fortunately, the advancement of professional recycling and disposal technologies has addressed the issue that used furniture “cannot be thrown away or transported”. Via a scientific process, the recycling of used furniture now enables efficient transportation and promotes resource recycling.

To do a good job in the recycling of used furniture, it is first necessary to clarify which furniture belongs to the category of “difficult to handle” so that targeted recycling work can be carried out. In terms of types, it is mainly divided into two categories: household furniture and office furniture. Household furniture includes bed frames, mattresses, sofas, solid wood or panel tables, dining chairs, wardrobes, dressers, etc., most of which are composed of a variety of materials such as wood, fabric, and metal connectors. Office furniture includes office desks and chairs, filing cabinets, conference tables, partition cabinets, etc., some of which also contain hardware accessories or metal frames. These pieces of furniture share the common characteristics of large size and non-single materials. When handled by individuals, they are difficult to classify, and the transportation efficiency is low. Direct landfilling will aggravate environmental pollution. Therefore, it is necessary to rely on professional recycling and disposal forces.

The professional used furniture recycle and disposal process has achieved the dual goals of volume reduction and resource recycling through a four-step process, providing strong support for efficient recycling.

The first step is preliminary disassembly. Workers will initially disassemble the complete used furniture, such as removing sofa covers and separating the metal brackets of bed frames, to break down large furniture into relatively regular parts. This step not only prepares for subsequent processes but also avoids equipment jamming caused by the irregular structure of the furniture, improving the smoothness of the entire recycling process.

The second step is continuous conveying. The disassembled furniture parts will be transferred to the metal chain plate conveyor by a grab bucket, and the conveyor will uniformly and continuously convey the materials into the main machine of the double-shaft shredder. Compared with manual feeding, this conveying method is not only more efficient but also can effectively avoid the safety risks of manual operation, ensuring the stable operation of the recycling and disposal line.

The third step is double-shaft shredding, which is the core volume reduction link in the recycling process. After entering the double-shaft shredder, the equipment breaks large furniture parts, such as wooden boards and sofa frames, into small pieces of materials through the dual effects of “tearing and cutting”. The volume reduction rate of the crushed materials can reach more than 70%, which greatly reduces the volume. Whether it is subsequently transported to the terminal disposal site for incineration power generation or harmless landfilling, or directly compressed, packaged, and stored, it can significantly reduce the floor space and transportation costs.

The fourth step is metal separation, which aims to realize the recycling of usable resources. When the shredded materials are conveyed through the discharge belt conveyor, the permanent magnet separator suspended above the belt conveyor will automatically adsorb the ferromagnetic substances in the materials, such as metal screws of furniture, steel bars of bed frames, and metal frames of filing cabinets. These substances can be accurately adsorbed and thrown into a special “metal collection box”. The collected metals can be further classified and processed, and re-smelted for processing, truly realizing “resource reuse” and reducing resource waste.

Compared with self-handling, professional recycling and disposal have obvious advantages and can better reflect the value of recycling. In terms of processing efficiency, disassembling a single piece of furniture by oneself often takes several hours, while professional disposal adopts an assembly line operation, with a processing capacity of up to tons per hour. From the perspective of environmental impact, self-handling is likely to cause garbage scattering and environmental pollution, while professional disposal reduces dust and material leakage through a closed process, resulting in less impact on the environment. In terms of resource utilization, it is difficult to recycle resources such as metals and wood through self-handling, but professional disposal can realize the separation and recycling of metals, and some wood can also be reprocessed. In terms of cost control, the cost of finding a vehicle for transportation by oneself is high, while professional disposal reduces the unit cost through large-scale operation.

The recycling of used furniture is not only an effective way to solve the problem of transportation but also an important measure to practice the concept of green environmental protection. When faced with the need for used furniture disposal, it is advisable to give priority to professional recycling and disposal institutions with compliant qualifications. This not only saves the trouble of personal handling but also contributes to the recycling of resources and environmental protection. It is believed that with the continuous improvement of the professional recycling system, used furniture will truly realize “turning waste into treasure” and inject more impetus into sustainable development.
