CoDOP technology makes "Phytomining of Gold" plausible
B. CoDOP MSW Resourcing
Municipal solid waste (MSW) is one of the most important resources in contemporary society. Unfortunately, most of it is wasted. There are two major technologies for MSW treatment today. The landfill method contaminants land and underground water, and the methane formed during the decay of organic materials is a more powerful green house gas than carbon dioxide. The method of MSW incineration is very expensive and generates a lot of poisonous, volatile gases such as fused-ring aromatics (PAHs), nitrogen oxides, sulfur oxides, etc.

A. CoDOP Biorefining
The “CoDOP technology” is the key for profitable biorefinery. CoDOP technology can convert biomass quantitatively into four products in a one-pot chemical reaction: two organic products (Product A, Product B), one inorganic products: high purity silicon dioxide (and a potential noble metals such as gold), and liquid fertilizer of nitrogen and phosphates. The value of the Product A as deep cleaning reagent for air and water, and soil remediation reagent; and the Product B as green deicer and carbon dioxide scavenger is higher than all the refining cost. The 3rd generation CoDOPA promotes the absorption of gold by specific plants. The concentration of gold in these plants is about 20-100 ppm. (Unlike cyanide that was proposed as the hyper-accumulator, CoDOPA is non-toxic and biodegradable). If these kinds of biomass are used as starting materials for biorefining, gold is a byproduct with negligible cost compared with its value (a biorefinery with annual capacity of 200,000 ton biomass has potential to produce more than 4 tons of gold).
CoDOP MSW resourcing is the only technology able to convert all MSW into useful products, and recover all valuable noble metals such as gold, silver, copper, platinum, etc. A one thousand ton/year operation system is optimized in China (see photo right). The cost of products is comparable or even lower than petrochemical products. No sorting is used for MSW (sorting MSW is almost impossible due to the complex characteristics of MSW) before resourcing. CoDOP MSW resourcing can solve two critical problems for California: Drought and Air pollution (picture below).
The products made from biomass using CoDOP technology not only have much higher performance, but also a lower cost compared with comparable products currently on market. The cost of using Product A in deep cleaning mercury from industrial waste gases is less than 0.3% compared with the ACI method. Our invented soil remediation reagent has comprehensive remedying capability, with a cost that is less than 5% compared with that of known technologies. Bio-based green deicer made with CoDOP technology is about one third of the price of petrochemical products. Noble metals such as gold are a byproduct of the refining process. The manufacturing cost of gold is negligible compared with conventional mining technologies.
The reactor has a diameter of 18 cm and is installed inside the insulation. For the purpose of detailed analysis of the hydrolysis, six sensors of temperature and six sensors of pressure are installed evenly into the reactor
