These EPDs are made public on the SuMPO Environment Label Program website:
・Low-carbon concrete Slagrete® BA (specified compressed strength 42 or under),・Low-carbon concrete Slagrete® BA precast products (Fc = 36N /mm²).
※1 ECOLEAF (SuMPO EPD) is a Type Ⅲ Environmental Declaration EPD (Environmental Product Declaration) operated by the General
Incorporated Association of Sustainable Management Promotion Organization (SuMPO). In the EPD, environmental information about aproduct is quantified using the life cycle assessment method denoted by ISO 14040 and 14044, and the product's ecological data thatpassed third-party verification by ISO 1402b5 are disclosed on the EPD program website.

'Slagrete® BA' features and examples of adoption
The conventional Slagrete® 70 has mainly been applied tounderground structures of buildings, but we, in collaboration with
Nishimatsu Construction, Co., Ltd., have developed a "Slagrete®
BA" that can also be applied to superstructures of buildings.
"Slagrete® BA" is a concrete manufactured with a mixture ratio of
50% Ordinary Portland Cement and 50% Blast Furnace Cement Type B
derived from construction by-products, capable of reducing
greenhouse gas emissions by approximately 20% *3 during the cementproduction process.

Precast product of Slagrete® BAWe have decided to utilize the "Slagrete® BA" manufactured at our Narita Factory as a half-precast
concrete floor slab in the new "TODA BUILDING" currently under construction. The utilization of
precast concrete produced in our factory offers advantages such as stabilization of concrete quality

and shortening of construction periods.
In response, our Narita Factory intends to proactively tackle thereduction of CO2 emissions during manufacturing by employing aphotovoltaic power generation system of approximately 560kW and a
200kWh storage battery.
※3 The data is an estimation based on our private measures and not EPD's information.
No information about this reduction ratio has been validated by the 3rd accreditationof SuMPO EPD.

Future Prospects
We will continue actively using the ECOLEAF (SuMPO EPD)
certification system and strive to disclose information on
environmental loads such as carbon footprint. We are also
pushing to reduce Scope 3 Greenhouse Gas discharging.
By expanding the 'Slagrete®' lineup suitable for bothsuperstructure and substructure of buildings and obtaining
EPD, we make it feasible to reduce the embodied carbon ofbuildings at large, facilitating resource circulation.
Aiming to realize a carbon-free & circular society, we planto actively promote and unfold this technology inarchitectural and civil engineering sectors.
