Developing Fertilizer from Recycled Drying Agents

The Center has focused its attention on the superior lime contained in the non-standard products resulting from the production activities of drying agent manufacturers and the contents of drying agents that have been returned to these manufacturers. Pursuant to developing a fertilizer from these recycled drying agents, the Center has scrutinized methods for, amongst other things, extracting this lime, utilizing it as a binding agent, and production methods appropriate for crushed slaked lime.

Developing a Slag Foaming Inhibitor for Steel Production by Utilization of Ceramics Production Waste Products

Utilizing clayish substances recovered from waste water that is a byproduct of the production of sanitary earthenware (i.e., waste water drainage from ceramics production) and the sludge recovered from paper recycling activities, the Center has developed a slag foaming inhibitor that exhibits increased strength and specific gravity when compared to traditional products.

An Effective Public System for Disposable Diaper Recycling

The Center duly studied the application of a system for collecting pulp from used disposable diapers, and also considered collection transportation methods, safety and other issues related to this pulp. The Center has also provided much-needed support to help realize the industrial application of these processes.
With regards to Omuta Ecotown, the recycling plant here has been in operation since March 2005. It received the Special Committee Chairmanfs Award at the 2006 Wastec competition.

Compost Quality Index Research Group

This group has carried out research and study related to temperature discernment methods and a labeling system for compost. Pursuant to these efforts, they have also developed simple evaluation tools and put them into practical use.
This group received a Global 100 Eco-tech Award at the Worlds Fair in Aichi Prefecture.

Research Group Dedicated to Utilizing Soy and Red Bean Curd Lees for a Highly Functional Method of Cultivating Mushrooms

This group has developed a method for developing red bean lees as a bedding medium for Bunashimeji (Beech) mushrooms. The sugar components, antioxidants and other components contained in the red bean lees are transferred to the bedding medium, making high value-added mushroom production possible.

Chemical Recycling of FRP Waste

FRP waste is subject to glycol analysis, with technologies involving re-synthesis of unsaturated polyester as well as the re-utilization of re-synthesized unsaturated polyesters as FRP products (mannequins, etc.) having been established.
This effort was recognized by a Special Committee Chairmanfs Award at the 2005 Wastec competition.

Tonkotsu (Pork Bone) Recycling Research Group

This group has developed a method of recycling the leftover pork bones used for soup stock at ramen shops and other establishments for use as fertilizer. Going by the name of gFukuoka Tonkotsu Meal Fertilizer,h this product is being sold at Nafco home centers.
This group has developed a method of recycling the leftover pork bones used for soup stock at ramen shops and other establishments for use as fertilizer. Going by the name of gFukuoka Tonkotsu Meal Fertilizer,h this product is being sold at Nafco home centers.
  • This fertilizer is made from the pork bones left over from well-known Fukuoka ramen shops. Sales of gFukuoka Tonkotsu Mealh have begun (as of 4/20/2006).
  • Now gFukuoka Tonkotsu Mealh, the recycled fertilizer created pork bones left over from ramen, is available in 700 gram bags (as of 4/7/2007)

Collaborative Research Project Results

Research and development involving biogas and utilization systems for liquid fertilizer developed from kitchen waste and other organic waste matter

Kitchen waste produced by households is fermented and methane gas is collected as an energy source. At the same time, the digestive fluids used in this process (the liquids that remain after the fermentation process) are returned to agricultural lands in the form of a liquid fertilizer and a kitchen waste recycling system based on the consumption of local agricultural products is established.
Operations in Ooki Town commenced with the Ooki Recycling Center Kururun in November 2006.

Development of an Advanced Recycling Technology for Shochu Dregs

The Center has created a system for the efficient recovery of shochu dregs, and has also developed manufacturing technologies for anti-viral products, fish fodder, soil germicides and insecticides where the main ingredient is these dregs.
This effort was recognized with the Global 100 Eco-tech Award at the Worlds Fair in Aichi Prefecture.

Development of Recycled Products from Waste Glass

Using a technology that creates a foam-like material from waste glass, the Center manufactures a sponge-like, high-quality lightweight aggregate and has created a recycling system for glass that utilizes this aggregate. This has led to the development of multi-purpose manufactured goods such as rainwater/groundwater percolation containers as well as lightweight fill construction materials.
Rainwater percolation products are now being manufactured and sold.

Development and Industrial Utilization of Products Created by Means of New Energy Conservation and Recycling Technologies That Utilize Hazardous Wastes Such As Sewage Sludge Ash

A non-heat treatment ultra high-pressure vacuum forming technology is utilized to develop tile products made from sewage sludge ash. The promotion of the utilization of these products has led to the creation of a recycling system.
The Shikkui ceramic finish gives these tiles an earthy, Japanese look. Available as of April 1, 2007.
  • A non-fired Shikkui plaster ceramic that consists of 55% sewage sludge ash has been developed.

The Development of eAll-Woodf Composition Cedar Pallets That Utilize Waste Wood Generated by Forest Thinning Activities

They have developed cedar pallets made from waste wood generated by tree thinning activities. These pallets are made without nails.
Available as of April 1, 2007. Dyden Corporation uses these pallets.
  • The Center has developed eall-woodf composition cedar pallets by utilizing resources made available by tree thinning activities (8/28/2007).

Research and Development Related to Making Practical Use of Recycled Products Made From Non-Woven Polyester Remnants and Other Scrap Materials

The aim of this research and development effort is the development of recycling technologies for non-woven polyester remnants, as well as rendering recycled products more useful.
These products are used as an under-floor acoustic material by major automobile manufacturers.
  • This recycled non-woven polyester product is used by Toyota as an under-floor acoustic material (as of 4/27/2006).
