Key innovations
The innovation lies in efficiently converting non-metallic components of waste circuit boards into high-performance adsorbents. The preparation process is simple, the cost is low, the temperature is low, and the adsorbent has strong adsorption capacity and is easy to regenerate, realizing high-value utilization of electronic waste.
Potential economic benefits
Turn waste into treasure and save waste treatment fees. Low preparation cost, high adsorption efficiency and easy regeneration. Great market potential and significant economic benefits.
Potential climate benefits
Turn waste into treasure and reduce carbon emissions from landfill incineration of electronic waste. Low-temperature and low-consumption production and regeneration reduce the carbon footprint of the adsorbent throughout its life cycle. Replace traditional high-energy-consuming materials and indirectly reduce carbon emissions from the extraction and processing of primary resources.

Solution details
The invention uses non-metallic components of waste circuit boards as raw materials to produce useful adsorbents through a simple chemical process. Adsorbent materials can be used to remove heavy metals from wastewater. The production process of converting e-waste into adsorbent is simple, low in cost and low in processing temperature, and the output of adsorbent is also high. The resulting adsorbent has a high surface area and an adsorption capacity similar to that of other existing resins. The adsorbent regeneration operation also requires simple steps.
