Adsorption of CO2 from waste cement and concrete

Around the world, various efforts are being made to transition to a circular economy. In the construction industry, especially in the concrete and cement industry, efforts toward carbon neutrality are accelerating worldwide.

It is said that concrete is currently poured at more than 4,000 sites per day in Japan.

Almost all of these sites use "feed-in material," which is said to be one of the causes of residual concrete and returned concrete.

We have developed a product called "RUBURI," which utilizes bamboo site as an alternative to "advance material. Through its widespread use, we will contribute to the reduction of waste and CO2 emissions at construction sites.

Promoting a recycling-oriented business model from Shizuoka through public-private partnerships

TAKECITE has signed a partnership agreement with Obayashi Corporation, Suzuyo Shoji Co., Ltd. and Mitsubishi Shoji Kenzai Corporation to participate in the Shizuoka DAC Project, which will contribute to the realization of a decarbonized society.

The project will produce recycled calcium carbonate "Takecite" from ready-mixed concrete sludge, an industrial waste, using Direct Air Capture (DAC) technology. By developing this material for use in a wide variety of products, we aim to realize a decarbonized society.

Toward a sustainable business model unique to Japan

The history of Takecite's research and development dates back to the Showa period. At that time, it did not attract much attention due to its low economic impact. However, with the advent of the 2022 era, there are high expectations for Takecite as a new seed of innovation. Japan's social issues, such as the declining birthrate and aging population, are important issues that will affect the future of the Japanese economy. In addition to these social issues and economic trends, the Paris Agreement on greenhouse gases has become a major global opportunity, and a commitment to environmental issues at the national level is now required.

Against this backdrop, the Takecite business, which is rooted in Shizuoka and has been steadily developing, has the potential to create a virtuous cycle for the environment, society, and the economy. We aim to create a business model that integrally improves these three elements, and we will continue to work toward the realization of a better future.
