【Urban Renewable Resources】Sofa Mattress Furniture Shredder: A Profitable Artifact that Processes 30,000 Tons of Garbage Annually

1. Dilemma and Solution for Large-Piece Garbage Disposal

The world produces 2.1 billion to 2.3 billion tons of waste furniture (equivalent to 1 billion sofas) every year. Traditional landfilling not only occupies 600 million square meters of land, but also causes 300 billion yuan of resource waste per year. The double-axis shredder can decompose a 2-meter-long leather sofa into the following in 90 seconds through the dual forces of "shearing + tearing":

Metal springs (purity ≥ 90%) → direct remelting

Wood chips (particle size ≤ 30mm) → manufacturing recycled boards

Sponge/fabric fiber → RDF fuel (calorific value 4500kcal/kg)

According to the actual measurement data of an environmental protection base in Guangzhou, a single device can process 50 tons of waste per day, and the resource conversion rate is 8 times higher than that of manual disassembly.

2. Analysis of the core technology of the equipment
1. Impact-resistant dual-axis system
Adopting 42CrMo alloy blade shaft (hardness HRC58-62), equipped with hydraulic overload protection device, it can withstand the instantaneous impact force of mattress springs (≥2000MPa). The German Siemens PLC control system adjusts the speed in real time (15-40rpm) to ensure the optimal energy consumption when processing different materials.
2. Intelligent sorting module
Metal detection: Eddy current sorter accurately separates iron/copper/aluminum, with a recovery rate of 92%
Fiber identification: Near infrared spectrometer (NIR) distinguishes cotton, linen and chemical fiber, with a purity of 85%
Dust control: Pulse dust removal system makes the PM2.5 in the operation area lower than 30μg/m³

III. Full path of commercial realization

1. Deep processing of recycled materials
Metal: The price of 304 stainless steel wire is 300% higher than that of scrap iron
Wood fragments: pressed ecological board (profit margin 35%)
RDF fuel: cement plant purchase price 600 yuan/ton
2. Carbon asset development
According to international authoritative organizations, every ton of furniture processed reduces 0.78 tons of CO₂ emissions. Based on the current carbon price of 60 yuan/ton, a 50,000-ton processing plant will increase annual revenue by 2.34 million yuan.

3. Equipment Selection Guide
Small community station: Recommend XD-800 (15-20 tons/day), investment ≈ 600,000 yuan
Municipal treatment center: Choose XD-2000 (50 tons/day), equipped with intelligent sorting system
Industrial project: Customize XD-5000 (100 tons/day), need to match exhaust gas treatment equipment
