Municipal Solid Waste Treatment Plant Business
Since developing waste incineration technologies using
proprietary technology and delivering Japanʼs ﬁrst fully
continuous mechanical waste incineration plant in 1963,
Takuma has built more than 360 municipal solid waste
treatment plants in Japan. Subsequently, we haveintroduced numerous new technologies and achieved theNo. 1 share of plant deliveries in Japan. Today, we continue
to reﬁne our technologies and embrace the challenge of

operating to the highest possible standards.
Takuma will continue to contribute to stable regional
waste treatment by pursuing integrated initiatives ranging
from the construction of municipal solid waste treatment
plants to after-sales service for those facilities through abroad product line and service based on an extensive trackrecord as the industryʼs leading company.

Stoker-type incinerators are the most common type of waste treatment plant in Japan, and they are a ﬂagship Takuma
product. Today, most incinerators operated by local governments throughout Japan use this treatment method, and Takuma
delivers secure, safe, stable, and highly efﬁcient waste treatment in response to customersʼ needs through advanced technology

70%* of all Japanese municipal solid waste treatment plants, which comprise a key type of infrastructure, have been operating for atleast 15 years, and demand for updating plants and extending their service life is growing due to their aging. Using the advanced heatutilization and energy-saving technologies we have developed as a boiler and environmental plant manufacturer, Takuma helps extend
plant service lives and reduce CO2 emissions through high-added-value primary equipment improvement projects. *According toresearch conducted by the Ministry of the Environment in 2018 and reported in “Municipal Solid Waste Emissions and Disposal.”Long-term comprehensive operation business
The Long-term comprehensive operation business, inwhich customers enter into contracts covering both
operation and maintenance management for a term of 10
to 20 years, has become the most common approach in theindustry in recent years, for example in the form of DBO
projects.
We have currently collected plant operating andmaintenance management data for more than 10 municipal
solid waste treatment plants with, which we use

Water Treatment Plant Business●

Takuma has delivered numerous systems, particularly in relation to technologies for advanced treatment of wastewater, in aneffort to help conserve the aquatic environment.
The recent trend is for plants to be called upon not only to purify water, but also to reduce power use by treatment
equipment and create energy from sewage sludge. In an effort to meet these requirements, Takuma has been focused on
developing a step grate stoker type sewage sludge incineration and power generation system and implemented technologies
using waste heat from the incineration process to generate electricity.
Going forward, we will continue to help conserve the aquatic environment by supplying products that meet the needs of ourtimes.

Measures undertaken to improve the quality of public
water sources and the need to reuse treated sewage are
spurring demand for more advanced water treatment.
Upﬂow moving-bed sand ﬁltration systems (Uniﬂow Sand
Filter), which eliminate suspended solids (SSs) from water,
are used in a variety of ﬁelds, including in ﬁnal processing
at sewage treatment plants and in pre-processing to remove

This project, through which the city of Miyazu and the towns of Ineand Yosano are seeking to realize a safe and hygienic living
environment, was about more than just fulﬁlling the basic role of awaste treatment facility. Reﬂecting its belief that the project is one inwhich a new future can be pioneered through advanced biomass
utilization technologies, the Takuma Group sought to create a modelcase demonstrating how a project could help create a Sound
Material-Cycle Society. In undertaking the project, we identiﬁed threecore concepts: providing peace of mind and vitality to the region,
protecting the environment and coexisting with nature, andsupporting a sound material cycle into the future.
●

Similarly, in planning the facility, we identiﬁed three designconcepts: nature, history, and people. In addition to adopting a designthat blends into the areaʼs rich natural environment, we incorporated
the distinguishing shapes of the regionʼs traditional arts and crafts into
the design, along with features that express gentle hospitality towardvisitors, for example through the natural warmth of wood.
As it turned out, the construction phase posed many unexpectedchallenges, including the discovery of underground obstructions andﬂooding in a waste pit due to heavy rainfall. Nonetheless, we wereable to overcome these obstacles to complete a facility whose
advanced equipment is unique in Japan.

Project Story

The complex consists of an energy recovery-type waste treatment facility (waste incineration +methane gasiﬁcation) and a material recycling facility. The methane gasiﬁcation facility ferments
waste, paper, and other material that makes up the combustible waste stream to produce
methane, which is then used to run a gas generator, allowing it to be recovered as electricalenergy. Electricity that remains after certain local load requirements are met can be sold back to
the grid.
In designing the methane gasiﬁcation facility, we worked hard to precisely apply the expertise
we have gained through past experience and to incorporate the latest information about otherstate-of-the-art facilities into the plant after a careful vetting process.
It is our hope that in addition to its basic role of treating waste in a hygienic manner, the plant
will contribute to material recycling and to the effective use of biomass energy.

The facilityʼs location next to Yoza-Amanohashidate IC about 10 minutes by car from Amanohashidate,
one of the three most famous scenic spots in Japan, makes it a picturesque destination in its own right.
Although the greatest concern when construction began in January 2017 was delays caused byaccumulated snowfall during the winter, the project was blessed with a comparatively mild winter.
However, in addition to boulders and other underground obstructions, a variety of problems, including
inﬂows of muddy water caused by heavy rainfall in nearby mountainous valleys, impacted theconstruction schedule and led to a delay of about 11 months after discussions with the customer.
We were able to overcome the challenges with the customer in cooperation with a local generalcontractor with whom we shared the construction work, sharing information about problems arising ineach scope of the plant construction and the civil work, and revamping the schedule.
Our hope is that the facility, which was completed thanks to the understanding and cooperation of thecustomer and local residents, will continue to operate and develop as a site that can contribute to theregion as part of Takumaʼs comprehensive operation business.
