Japan is almost 100% dependent on imports for its mineral resources. In the future, minor metals and precious metals in particular will continue to be important resources, and securing these resources is essential to maintaining and strengthening international competitiveness. One of the measures to secure mineral resources is the reuse and recycling of minerals contained in sludge, which will contribute to environmental protection and reduce greenhouse gas emissions. Phosphorus, which is currently imported from China, is also an indispensable mineral. Therefore, the extraction of phosphorus from sewage sludge is being promoted as a national project.
The reuse and recycling of sludge from wastewater treatment plants is becoming increasingly important for environmental protection, decarbonization and securing resources that are currently dependent on imports.
After dehydration, many of the dried sludge objects, whether organic or inorganic, are found in a lumpy form. With KENKI DRYER, the dried objects such as lumpy sludge are crushed to some extent inside the dryer, and by reducing the surface area, drying can be carried out thoroughly even inside the dried objects. Even with clumpy dried objects, there are cases where the adhesive quality is strong during drying and clogging occurs inside the dryer, and the dried objects cannot be discharged, but with KENKI DRYER, the unique mechanism of the world patent prevents clogging inside the dryer, and the dried objects can be dried smoothly.
In addition, sludge discharged from wastewater treatment plants tends to form lumps during the drying process due to the effect of flocculants used in wastewater treatment. When the material to be dried forms lumps, the heat does not spread sufficiently throughout the material and the inside of the material does not heat up, so only the surface dries and the inside does not heat up and dry. Even if the material to be dried forms lumps, the KENKI DRYER can dry the inside of the material sufficiently by crushing and reducing the size of the material to some extent inside the dryer and reducing the surface area.
By drying the sludge discharged from wastewater treatment plants at low temperatures, the components of the sludge change little after drying, making it possible to use it as a compost, soil conditioner, fuel, etc. as an upcycled product. KENKI DRYER uses steam as a heat source for indirect drying at low temperatures, so the components of the dried material change little after drying, making it possible to use it as an upcycled or recycled product.
KENKI DRYER, which has 11 patents in 8 countries, is a steam indirect dryer, but it is a completely unique product with a different structure from other steam indirect dryers. Direct-fire dryers, such as those that use burners, emit carbon dioxide, which is bad for the environment and goes against the trend of decarbonization. Because they dry at high temperatures, they use a lot of fuel and their parts wear out quickly, making them expensive to maintain.
KENKI DRYER uses steam as a heat source, but because of its high drying heat efficiency, it only needs a small amount of steam, so you can use the steam you’re currently using, and if you use excess or surplus steam, you don’t have to pay for fuel. The dryer doesn’t emit carbon dioxide when it dries, so you can dry without carbon dioxide. Alternatively, by installing an electric or hydrogen fuel boiler, there is no emission of global warming gases or carbon dioxide CO2 during the drying process.
In addition, there are no problems after start-up, and the rotation speed of the dryer’s main body blades is very slow at less than 5 rpm, so there is little wear and tear on parts, and maintenance is easy and inexpensive. KENKI DRYER is a continuous drying system, in which the drying material to be dried is stored, rather than a batch system. Therefore, operation is simple and unmanned operation is possible 24 hours a day.

| ■ Self-cleaning screw / Steam Heated Twin Screw Technology （ SHTS technology ） |
One of the International Patented Technology that KENKI DRYER has is a self-cleaning structure called Steam Heated Twin Screw technology (SHTS technology). No matter how materials are sticky, adhesive and viscous is, they can be dried without clogging inside of the dryer because of this unique structure that no other products has.
For example, even materials stuck to the blades of one screw, blades of the other screw in the dryer’s body forcibly peels the materials off as they rotate. Since the blades rotate by peeling the material off each other, any sticky, adhesive and viscous material does not adhere to the blade, and the blades continue rotating, peeling, agitating and heating material without stopping while they carries material further. Also, since surface of blades are always renewed and kept clean, heat near the blades is not blocked and it is conducted directly into the materials.
| ■ Product characteristics |
KENKI DRYER has three main characteristics. They are 1) Any materials can be dried as expected including sticky, adhesive and viscous materials and raw material slurry that no other company can deal with, 2) dried material can by recycled or utilized as raw materials because of its low-temperature drying method, and 3) there is no need to assign operator since its continuous operating system makes 24 hours unattended operation possible.
| ■ Drying process |
The unique and original drying mechanism of KENKI DRYER is also International Patented Technology. Because 4 drying mechanisms which are crashing drying, agitation drying, circulation drying and indirect drying work simultaneously and add heat to material being dried repeatedly and continuously, inner part of the material is dried thoroughly and quality of discharged material after drying is stable. This series of drying mechanisms prevents agglomeration which causes insufficient drying from feeding process of the material into the dryer until discharging process after drying completed. Various ingenuities to conduct heat surely into inner part of the materials are exercised and stable heating and drying are proceeded continuously.
| ■ Heat source, Saturated steam |
Even KENKI DRYER uses only saturated steam as its heat source, it is outstanding in safety and hygiene point of view with its unique drying mechanism based on combined use of conductive heat transfer method and heated air method. Since steam is a stable heat source, quality of discharged material after drying is also stable and equable. Maximum allowed steam pressure is 0.7Mpa and adjustment of steam pressure, adjustment of drying temperature in other words, can be easily done. Saturated steam is commonly used in many factories so that it can be said as a familiar and handy heat source. In comparison with drying methods using burner or hot blasts, saturated steam method is an indirect drying applying heat exchange via pipes that steam is passing through, therefore, it hardly burns the materials and is outstanding in safety and hygiene point of view.
Precious metals are rare, naturally occurring metallic chemical elements of high economic value. Precious metals, particularly the noble metals, are more corrosion resistant and less chemically reactive than most elements. They are usually ductile and have a high lustre. Historically, precious metals were important as currency but they are now regarded mainly as investment and industrial raw materials. Gold, silver, platinum, and palladium each have an ISO 4217 currency code.
The best known precious metals are the precious coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art, jewelry, and coinage. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.[1] The demand for precious metals is driven not only by their practical use but also by their role as investments and a store of value. Historically, precious metals have commanded much higher prices than common industrial metals.

An urban mine is the stockpile of rare metals in the discarded waste electrical and electronic equipment (WEEE) of a society. Urban mining is the process of recovering these rare metals through mechanical and chemical treatments. In 1997, recycled gold accounted for approximately 20% of the 2700 tons of gold supplied to the market.
The name was coined in the 1980s by Professor Hideo Nanjyo of the Research Institute of Mineral Dressing and Metallurgy at Tohoku University and the idea has gained significant traction in Japan (and in other parts of Asia) in the 21st century.
Research published by the Japanese government’s National Institute of Materials Science in 2010 estimated that there were 6,800 tones of gold recoverable from used electronic equipment in Japan.
