What Happens to Your Old Sofa? The Industrial Process Behind Bulky Waste Recycling
In the future, SID will continue to optimize integrated solutions and refine every piece of equipment, helping more cities and projects achieve efficient resource recovery from bulky waste through stable and reliable production lines.

SID | Why Waste Sorting Matters
Many regard waste simply as "discarded items" that can be mixed without consequence. Yet, within waste management systems, household waste is far from worthless—it is a mixture of resources waiting to be unlocked. The purpose of sorting is to reduce waste, increase recycling rates, and alleviate urban environmental pressure.
