オデッサ・テクノス List of Products and Services

Our company operates an intermediate treatment business using our developed sludge treatment plant, the "Odessa System," to granulate and solidify industrial waste sludge. We also sell improved soil and fluidized treatment soil made from improved soil. The "Odessa System" mixes and stirs inorganic sludge, such as construction sludge, with special solidifying agents, allowing for rapid granulation and solidification while retaining moisture. This process enables 100% recycling of the material as improved soil for embankments, backfill, subgrade materials, and levee materials. Our intermediate treatment facilities are located in Sapporo City and Ishikari City, Hokkaido. Our related intermediate treatment facility is Sendai Odessa Co., Ltd. in Sendai City, Miyagi Prefecture. The "Odessa System" can also handle on-site sludge treatment (mobile): - On-site sludge treatment eliminates the need for collection and transportation costs. - Its compact and easily movable design significantly reduces transportation and installation costs. - On-site processing allows for the reuse of waste without removing it from the site. We also offer sales and rentals of the sludge treatment plant "Odessa System."

The "Odessa System" is a sludge recycling treatment plant that eliminates the need for dehydration, drying, and incineration processes through granulation and solidification treatment. By mixing and stirring special solidifying agents with inorganic sludge (industrial waste) such as construction sludge, it can be granulated and solidified in a short time while still containing water, allowing for re-resource utilization as civil engineering materials. Moreover, the granulation treatment of sludge using the Odessa System is very simple, with a modification time of only about 2 to 3 minutes. Additionally, it can be operated not only as a "fixed sludge treatment" where the treatment facility is set up (fixed) at a processing site to which sludge is transported by collection and transportation vehicles, but also as a "mobile sludge treatment" where the Odessa System is brought to the site of sludge generation for on-site modification and recycling. 【Features】 - Compact facility with unit design, easy to install and remove - Automatic control of solidifying agents and automatic recording of treatment results - Complete recycling after treatment, exempt from industrial waste tax - No installation permit required for industrial waste treatment facilities *For disposal operators, a permit for "industrial waste disposal business" is required. If the generating business conducts "self-treatment," neither permit is necessary.
