Recycling and Reuse of Waste Lithium Batteries

The 7th-generation full-process technology overcomes the safety hazards, low efficiency, and heavy pollution associated with traditional recycling methods (“discharge + crushing + incineration + pulverization”), achieving efficient, safe, green, and intelligent resource utilization of waste lithium batteries. It stands as one of the leading physical recycling solutions both domestically and globally, abandoning the low-end brine discharge pulverization method.

Household Waste Sorting

Anaerobic pyrolysis technology for organic matter from sorted municipal solid waste, commonly referred to as pyrolysis gasification technology, represents an advanced solid waste thermal treatment method. Its core principle involves heating sorted and concentrated organic waste (such as food waste, paper, plastics, rubber, straw, wood, textiles, etc.) is heated to specific temperatures (typically between 350°C and 800°C). Through thermochemical processes, complex chemical reactions occur within the organic macromolecules, including pyrolysis, dehydrogenation, and polycondensation. This ultimately converts the material into three forms of high-value products:

Thermal Pyrolysis Treatment for Resource Recovery of Waste Phosphogypsum

This technology is a harmless, volume-reducing, and resource-recycling treatment method for waste phosphogypsum—a byproduct of the phosphoric acid industry. Its core employs an oxygen-free pyrolysis process, achieving efficient solid waste conversion by regulating temperature (200–750°C) and reaction conditions.

High-temperature pyrolysis

1. Resource Recovery: Converting waste into energy and chemical feedstocks to generate economic value; 2. Significant Volume Reduction: Dramatically decreasing waste volume and weight (typically 70%-90% reduction); 3. High Safety: Furnaces equipped with 2-4 safety explosion-proof systems to prevent explosions caused by high oxygen content; 4. Minimal Secondary Pollution: The oxygen-free environment suppresses the generation of highly toxic substances like dioxins and furans at the source; 5. Carbon Sequestration Potential: The resulting biochar possesses stable properties and can be buried in soil for long-term carbon fixation, representing a form of negative carbon technology.

Thermal Treatment for the Safe Disposal of Hazardous Waste

High-temperature, oxygen-deprived environments effectively decompose organic toxins such as persistent organic pollutants (POPs). Harmful components in waste—including sulfur and heavy metals—are largely immobilized within carbon black, thereby avoiding issues associated with incineration such as melting and fly ash generation.
