Construction and commissioning

Procurement and manufacturing
Waste treatment plants consist ofmultiple pieces of equipment. During the
procurement and manufacturing stage,
we manufacture this equipment at ourHarima Plant under a rigorous quality
control system while carefully choosing
the optimal manufacturers to satisfy the
projectʼs cost and lead timerequirements.

During the construction and commissioning
stage, we manage the construction process,from civil and construction work to theinstallation and commissioning of plant
equipment. This management process,which addresses safety, quality, construction
process, and cost management, culminatesin the delivery of the completed facility to
the customer.

As a salesperson, I visited the site numerous times toensure that the customer would choose to entrust the
project to Takuma. The process leading up to ourreceipt of the order was a truly challenging one.
This effort had numerous components, including
precisely assessing the customerʼs needs; proposing a
project that would satisfy those needs; building
relationships of trust with the customer, local residents,and others; coordinating and negotiating with in-houseteams and outside entities; negotiating with othercompanies; and dealing with various problems as theyarose. Our hard work was rewarded and turned into
immeasurable pleasure when the customer made thefollowing response on a customer satisfaction
questionnaire after the project was completed andhanded over: “I believe that weʼve just seen one of thebest facilities of its kind in Japan completed.”

My involvement with this project began as we sought to work out thesystem that Takuma was going to propose after we received the order forthe project while listening carefully to the customerʼs requests. As an
example, we ended up changing equipment that uses waste heat fromincinerating waste at the facility from a hot water supply system to anelectricity supply system after a series of discussions with involved
agencies and other stakeholders so that the plant could supply theelectricity it generates to nearby facilities.
After the basic design was ﬁnalized, we were able to design a facility thatearned the customerʼs approval by explaining information including thecapacity, operating methods, and maintenance methods for all machineryand participating in numerous meetings.
The process leading up to the transfer of the facility to the customer
brought one challenge after another, and Iʼll strive to take advantage of
those experiences so that we can continue to deliver facilities that makecustomers happy in the future.

Takuma is helping protect the global environment through business activities consisting of an integrated approach that
extends from the design, manufacture, and procurement of equipment and systems to plant construction. This section
introduces the process that goes into bringing a municipal solid waste treatment plant online in one of Takumaʼs core businesses.

Expert staff members manage operations at each construction site ona daily basis to ensure that the facility will be completed as outlined indesign drawings and in a way that satisﬁes the customer.
As many as more than 500 workers worked on this plantʼs site everyday. Daily construction management included safety patrols to ensurethat workers were doing their jobs safely and a variety of inspections toverify that the plant was being built in accordance with drawings.
We also actively promoted exchanges with local residents to ensure
they understood the construction process and to give them peace ofmind, for example by inviting them to tour the site, by cleaning up thearea around the site, and by participating in community events.
I realized that all the hard work was worth it when the customersʼ
representatives expressed their gratitude at the completion ceremony
after construction was ﬁnished.

When operating a plant, we provide optimal
maintenance and management services that utilize
POCSYS, a proprietary system designed to provide
comprehensive support for plant operation,
maintenance, and management so the plant can live
up to its concept of providing safe and stable waste
treatment.
Going forward, we will go beyond plant operation,
maintenance, and management as we work to allow
the facility to bring local residents together and toplay a disaster prevention role by offering tours,
hands-on events, and disaster prevention training
together with local residents. In this way, the facility
will protect the community and earn a place inresidentsʼ hearts while simultaneously raising
environmental awareness, facilitating hands-on
learning, and disseminating information.

We reﬁne each plantʼs plan through repeated meetings with our sales
team and with the customer. While listening to the customerʼs wishes,
we offer a proposal that incorporates our expertise and work closely withthe sales team to earn an order. Once weʼve received that order, we
proceed with the plant design process while enlisting the cooperation of
the customer, public agencies, equipment manufacturers, and others.
The completed design drawings are handed off to our construction team,and once construction is completed, the engineering staff works with thecommissioning team to carry out inspections, offer instruction on plant
operation, and perform related tasks. Seeing the customerʼs personnel
working at the operating plant following its completion always gives me
a strong sense of how weʼre contributing to the customerʼs business.

Although the plant has only been operational for ashort time, we as a maintenance team will plan
periodic inspections and maintenance and carry themout safely so that the facility can operate in a stablemanner over the long term.
Weʼll also help increase the customerʼs proﬁtability
by maintaining a high level of performance withfunctional improvements and proposals for preventive
maintenance measures and other enhancements thattake advantage of our many years of experience andby eliminating unplanned stoppages.

I was involved with this wood chip biomass-fueled power plantinstallation project, which is Takumaʼs ﬁrst 2 MW-class power plant, as asite manager from the construction planning stage through toconstruction and completion of the facility. We worked especially hard to
stick to the schedule, ﬁrst, due to the projectʼs short six-month timeline,
which included four months for construction and two months forcommissioning, and second, because it didnʼt differ from a large power
plant in terms of the number of pieces of equipment, even though it was
only a 2 MW-class facility. Thanks to the cooperation of the customer
and other involved parties, we were able to complete the project ontime. I hope the plant will be able to promote local employment andhelp revitalize the forestry industry by using unused lumber.

3. Water Treatment Plant Business(Related SDGs)

More than 50 years have passed since Takuma entered the water treatment business. To date, we have helped improve thewater environment by building water treatment facilities. Recently, the industry has been called upon not only to improve thewater environment, but to reduce the amount of power that treatment equipment consumes and to create energy from sludge.
Energy-saving and energy-creating products play key roles in the industry, particularly at sewage treatment plants, and weremain committed to helping realize sustainable sewage systems.

4. Activities of Our Overseas Business(Related SDGs)

Overseas Energy from Waste plant business

The biomass-fueled power generation boiler business in Southeast Asia is an essential part of any discussion of Takumaʼshistory. We have delivered more than 370 biomass boilers to customers overseas, and we have an especially extensive trackrecord since 1959 of delivering boilers fueled by bagasse (ﬁber remaining after sugarcane is crushed) in Thailand, where we havea local subsidiary. Takuma takes pride in having supported the Thai sugar industry for many years.
As the feed-in tariff program for renewable energy becomes increasingly well established in various industries, a growing
number of customers in Thailand are looking beyond simply gaining a source of power for plant operation and instead opting toconstruct boilers with the goal of using 10 MPa・520 C classboilers that operate at comparatively high temperature andhigh pressure levels to actively generate electricity for
resale to boost their income. In this way, demand for thistype of boiler facility is expected to continue to grow.
Under these conditions, we look forward to helping
supply environmentally friendly power from biomass,
particularly in Southeast Asia, by accommodating demand
not only in Thailand, but also in neighboring countries such
as Indonesia and Vietnam with reliable technology andﬁne-grained customer service based on our extensive
experience in the ﬁeld.
Sugarcane deliveries

Waste processing problems have been manifesting themselves in countries around the world recently due to the effects oftrends such as rapid urbanization, and there have been reports of various adverse effects of burying waste as-is on living
conditions, including soil pollution and ﬁres, especially in developing nations. Such countries are pursuing initiatives toresolve waste treatment issues, and demand for Energy from Waste plants has been growing with each passing year, seemingly
in proportion to the volume of waste being disposed of. Growth in construction of large-scale plants nonetheless remains
gradual. One cause of this mismatch between demand and construction is likely to be inadequacies in terms of programs,
ﬁnancing, and technologies as expectations concerning renewable energy combine with robust requirements with regard tosafety and environmental friendliness.
Takuma has deep experience and an extensive track record that together make it a market share leader in waste incinerationand processing equipment in Japan. The photograph below depicts a plant that we delivered to Lakeside Energy from Waste
Limited in the UK, one of a series of nine facilities we have delivered in various countries and regions, including China and theUK. Our Lakeside Plant in the UK and our Gaoantun Plant in Beijing have earned a high level of praise and trust from theirrespective customers, for example due to the facilities having achieved continuous operation for more than 8,000 hours a year.
We are conﬁdent that taking advantage of our extensive experience in the ﬁeld, working closely with stakeholders as weshare detailed information, and actively cooperating in order to solve waste treatment-related issues will allow us to better
deliver plants that operate in a safe and stable manner to bring peace of mind to the residents of those countries and regions.
We look forward to contributing to initiatives designed to encourage the adoption of waste power plants in the future bydrawing on the technological expertise that is our strength and partnerships with local companies and other entities topropose solutions to local needs.

Message

Main Recent Project●MessageI oversaw my ﬁrst overseas project in FY2017. Overseas projects pose unique challenges because
they tend to have larger boilers than domestic Japanese projects and because all interactions withthe customer during the design process must be carried out in English. I was relieved that we wereable to deliver this boiler plant to the customer without any issues. Iʼm looking forward to taking
advantage of the experience Iʼve gained from this project so that I can embrace the challenges ofsimilar projects in the future.

Recently, I've noticed a big increase in awareness around waste issues, be it in developed ordeveloping countries. But already for over half-a-century, Takuma has been providing environmental
technology solutions by designing and building hundreds of household waste treatment facilities. As
one of the few foreigners in Takuma, I'm working to bring our technology and expertise overseas andwhile these projects are very difﬁcult and complicated, the resulting facilities undoubtedly help
towards creating a cleaner environment for ordinary people and their communities.
