As professionals in waste treatment operation and maintenance, TESCO provides support to local public bodies with a one-stop service from consulting through to construction, remodeling, and operational maintenance. TESCO has an established reputation in operational know-how that ensures a long operating life for facilities, and we make a point to provide reductions in total costs. A feature of TESCO is that it also focuses on making a contribution to local regions. Operation and maintenance actively employ local residents, and the company works to ensure that acquired skills and know-how are passed on. As well as furthering understanding of waste treatment amongst local residents, TESCO is working to create opportunities, and thus contribute to the local economy.
Waste incineration started in the early 1960s, and together with the increase in size of facilities and the move to continuous operation, we have seen bewildering changes in operational maintenance methods, more restrictive laws and regulations, and advancements in energy reductions. TESCO's operational maintenance can rapidly change with the times, and as groundbreaking specialists in operations and maintenance, the company is charged with the operation and maintenance of waste treatment facilities (incineration facilities,
recycling facilities, non-combustible processing facilities, and final disposal locations). TESCO has engineering, construction, and consulting departments (details here), and through enhanced linkups between operations and maintenance, can handle comprehensive management roles and PFI business.
In the late 1970s, TESCO was commissioned to carry out incineration of waste in the Kanto area, and has subsequently also been commissioned to manage many other waste treatment facilities. At that time, outsourcing to the private sector was rare, with many such facilities being managed by local government. Currently, as times change, TESCO has been commissioned for night operations in some facilities, as well as management of a range of waste disposal facilities, as well as stoking methods, fluidized-bed methods, gasified furnaces, outsized waste treatment, recycling facilities, and final disposal locations. TESCO's operation and maintenance encourages the acquisition of qualifications with priority given to local employment, and by nurturing local technicians, aims for local management of facilities.
|■ Crane operation
Crane operation is an important part of incineration management. TESCO provides special training for personnel in how to operate cranes (less than 5t). Crane operation is important in ensuring stability of the waste, and for longer furnace operating life.
|■ Burnable waste incineration
Burnable waste is incinerated at a temperature between 850°C and 950°C. This waste comprises waste that burns easily and that which does not, therefore the status of the incineration is monitored 24 hours a day. Burnable waste is fed into the stoker-type incinerator, where it passes through the three stages of drying, combustion, and post-combustion, ending up as incineration ash. Good operation requires proficiency in controlling the speed of the grate, air quantities, and temperature management, and in all of these, TESCO uses highly skilled personnel.
|■ Monitoring from the central control room
The operational status of the facility as a whole is monitored 24 hours a day from the central control room. Any warnings generated in the facilities are also shared with the central control room and operating and maintenance personnel, enabling rapid response. TESCO is a specialist with years of experience in operating and managing incineration facilities, and supports facilities from all manufacturers.
