Takuma was founded in 1938 by Tsunekichi Takuma, who invented the first boiler to be produced entirely in Japan. The company, which has supplied efficient, easy-to-operate boilers that can burn a variety of different fuels, has helped resolve social issues like pollution and energy conservation while continually meeting customer needs.
We have accumulated a remarkable track record while developing and improving boilers that can make effective use as fuels and heat sources not only of fuels like coal, oil, and natural gas, but also materials that conventionally have not been utilized as sources of energy, including biomass, plant waste heat, household waste, and industrial waste. Today we continue to contribute to our customers and society by providing technologies that are essential in the creation of energy at waste incineration facilities and biomass power plants.Boiler Plants

As Japan’s postwar high economic growth spurred rapid growth in waste emissions and posed major challenges in waste treatment, Takuma applied the combustion technologies it had developed in connection with its boilers to deliver Japan's first 24-hour operating waste incineration plant to the City of Osaka. Since that time, we have delivered numerous plants as a waste incineration facility pioneer. As our own businesses have progressed along with the larger history of waste treatment, we have helped underpin society’s infrastructure while building the best record of any Japanese manufacturer in the industry in terms of the number of plants delivered by supplying waste treatment facilities that meet the evolving needs of society and customers, including in terms of dealing with pollution, addressing high-calorie issues posted by plastics, and utilizing energy contained in waste by means of high-efficiency electricity generation. Stoker-type incinerators

We have half a century of experience building waste incineration facilities since delivery of our first such plant in 1963. Takuma waste incineration facilities that remain operational in Japan can treat a total of about 24 million people’s waste.
As our long-term operation business receives a growing number of orders for services like operation, management, and maintenance of the plants we build, we continue to support public health and living environments in Japan by contributing to stable waste treatment over a typical plant service life of 20 years and beyond through not only construction, but also after-sales service.

Since exporting the industry’s first biomass boiler to Taiwan in 1949, we have developed sophisticated technologies and amassed a remarkable combustion track record for a variety of types of biomass, including lumber offcuts, building waste, unused materials, palm kernel shell (PKS), wood pellets, poultry waste, and bagasse (bagasse: fiber remaining after sugarcane is crushed).
Today, we construct numerous biomass power plants that use underutilized wood biomass as boiler fuel. We offer four combustion systems and can propose optimal, tailor-made systems in response to the type of fuel being used and a constellation of customer needs. In addition to contributing to customers’ businesses by supplying plants that will operate in a stable manner over the long term, we contribute to society by facilitating environmental conservation and helping address climate change through the effective use of biomass. Boiler Plants

Japan’s introduction of a feed-in tariff (FIT) program in 2012 spurred rapid growth in demand for the construction of biomass power plants. Drawing on the biomass combustion technologies we have developed, we are proud to have achieved the best delivery track record of any manufacturer under the FIT program by proposing systems that have been optimized to meet customers’ needs and delivering numerous plants.
In addition to contributing to customers’ businesses by proposing optimized, tailor-made systems in response to customers’ needs, for example to accommodate mixed use of fuels like unused materials and lumber offcuts, and realizing stable plant operation over the long term, we are contributing to society by facilitating environmental conservation and helping address climate change through the effective use of biomass. Biomass Power Plants

Since 1965, we have delivered plants that efficiently incinerate a diverse range of industrial waste from various plants and worksites, including wood chips, paper waste, waste plastic, oil sludge, waste liquids, sludge, and infectious waste.
In recent years, demand for the ability to effectively and efficiently use heat from incineration as energy by installing boilers, steam turbines, and generators is growing. We supply plants that help reduce the amount of power needed for facility operation, improve profits through the sale of electricity, and promote local industry by supplying heat off-site. Industrial Waste Treatment Plants

By using the energy contained in biomass and waste as heat and power, it is possible to help reduce CO₂ emissions.
The amount of power that the power plants we have delivered over the last 30 years can be expected to generate is equivalent to a reduction of about 4 million tons of CO₂ annually^*1, or about 0.3% of Japan’s CO₂ emissions^*2.
*1 Calculated for the municipal solid waste treatment plants and biomass power plants Takuma has delivered,the former is calculated based on the actual amount of electricity generated and the amount of residual heat used from the Ministry of the Environment's "Survey on General Waste Disposal," while the latter is calculated for plants delivered over the past 30 years, assuming 300 days of operation per year. Calculated based on the assumption that 50% of the power generated by municipal solid waste treatment plants, and 100% of the power generated by biomass power plants, contributes to CO₂ reductions.

Drawing on technologies for treating water and wastewater needed for boilers, we entered the water treatment field during the 1960s and have delivered a variety of products. Since we supplied our first sand filtration system in 1979, we have accumulated an extensive track record of deliveries of these systems for use in advanced treatment of sewage at sewage treatment facilities and in water treatment at water treatment plants nationwide.
Today, we continue to support a clean, healthy water environment while accommodating customer needs in terms of providing sufficient treatment capacity, reducing the number of installed pieces of equipment, and shortening installation times by supplying high-speed moving-bed sand filtration systems with two to three times the filtering capacity of previous systems despite being more compact in response to replacement demand for existing fixed-bed sand filter.
