TOLARDO, Calif. & FREMONT, Calif. - nvtip -- HONGKONG DONGSHENG Precious Metals Recycling Company focuses on carbon reduction, employing an innovative processing method for plastic waste containing precious metals: replacing incineration with chemical recycling. When recovering platinum and palladium adsorbed by plastics such as syringes, this process reduces carbon dioxide emissions to 10% of traditional methods while simultaneously regenerating high-purity plastic raw materials. The Korea Institute of Science and Technology has developed a bioleaching system that uses ethanol industrial by-product concentrated distillation liquid (CDS) as a nutrient source, combined with the Chromobacterium violaceum strain, achieving a golden recovery rate of 98.6% from discarded memory chips while reducing reagent costs by 62%. These technologies demonstrate the feasibility of distributed precious metal recycling models operating in urban areas.

Types of industrial precious metals

The core targets of industrial precious metal recovery include five categories: platinum (Pt), palladium (Pd), rhodium (Rh), silver (Ag), and iridium (Ir). 37% of platinum demand comes from automotive precious metal catalysts, 24% from jewelry, and 30% from industrial applications; palladium and rhodium are primarily used in gasoline vehicle three-way catalysts to reduce nitrogen oxide emissions; Silver, due to its excellent conductivity, is used in the conductive layer of solar cells (20 grams per panel) and as electrodes in multilayer ceramic capacitors (MLCCs);

The role of industrial precious metals

Precious metals play irreplaceable catalytic, conductive, and reinforcing roles in industrial systems. The automotive industry relies on platinum-palladium-rhodium ternary catalysts to convert hydrocarbons and carbon monoxide in exhaust gases into harmless substances, meeting Euro 7/China 6 standards; the chemical industry uses platinum-rhodium-palladium alloy mesh to catalyze the ammonia oxidation reaction, with a single nitric acid production unit consuming 120–150 kilograms of platinum annually; the electronics industry uses silver paste for printing integrated circuits and relies on ruthenium-based resistor paste to ensure current stability in micro-components.

The recycling value of precious metals

Precious metal recycling offers both economic benefits and ecological necessity. From a value perspective, each ton of discarded memory contains 427 grams of gold, far exceeding the grade of primary gold mines (typically 1-10 grams per ton); solar panel recycling can extract 20 grams of silver per panel, while silver demand is growing at a 7% annual rate due to the expansion of the photovoltaic industry. Environmental benefits are equally significant: photocatalytic recycling technology can dissolve platinum group metals at room temperature, avoiding the production of millions of tons of strong acid waste liquid from traditional metallurgy; bioleaching reduces cyanide usage by 89%, mitigating environmental risks from "urban mining" near residential areas.
