Management The Environment Collaborating with Society Conserving Biodiversity Conserving biodiversity in the course of doing business is a material corporate issue. Our approach to conserving biodiversity includes complying with strict legal requirements and striving to harmonize human activities with nature while interacting with the environment and wildlife in our cement and mineral resources business. Considering Biodiversity in Operations ▶ Investigation and Development Operations (mining) Post-mining (improvement of old quarry sites) • Environmental impact assessment • Protection of rare animal and plant species • Prevention of environmental disruption • Greening quarries • Use of old quarry sites Recently conducted environmental impact assessments • Redevelopment construction of the Fujiwara Quarry (February 2012) A post-project survey is currently underway. • Development construction of the Ofunato Quarry (June 2011) A post-project survey is currently underway. Representative Activities • Preservation and propagation of rare plants at the Minowa Quarry and Fujiwara Quarry • Prevention of noise, dust and water pollution pursuant to laws, regulations and local pollution control agreements •Safeguarding wildlife pathways •Protection of bird nesting grounds Results of Greening •Area of seeds sprayed: 17,000 m², tree seedlings planted: 4,000* *At the group limestone quarry in FY2015 Use of Old Quarry Sites •Large-scale solar power systems business (company-owned land: 8.5 ha)* *Quarry sites managed by Kansai Taiheiyo Minerals Corporation ● Environmental Impact Assessment Cement production starts with quarrying limestone, the primary raw material for cement. Since quarrying requires the removal of topsoil, it has a significant impact on the natural environment and landscape. Our quarry development is not solely related to quarrying. We are acting with the belief that it is important to care for the conservation of the local ecosystem and promote the development of the local economy. We therefore study and implement conservation measures to minimize environmental impact and strive to achieve sustainable quarry development while taking into consideration the opinions and ideas exchanged with the local government, community and academics. Aquatic life survey ● Protection of Rare Plant Species Since 1972 we have been protecting and nurturing rare species of native plants on Mt. Buko, the location of the Minowa Quarry of Chichibu Taiheiyo Cement Corporation (Chichibu, Saitama Prefecture). We created a botanical garden at the quarry and, together with local experts and other people, we preserve 65 native plant species there while increasing the plant population. Additionally, since 1995 our Central Research Laboratory has continued to research and develop ways to preserve and grow endangered plants, starting with primrose and miyamasukashiyuri and then adding lady’s slipper orchid and sanicula tuberculate Maxim in 2011, and to verify genetic diversity of native plant species using biotechnology. 42 G4-EN11, EN12, EN13, MM1, MM2 TAIHEIYO CEMENT CSR REPORT 2016 ● Protection of Water Resources In quarrying we pay close attention to protecting not only terrestrial plants but also water resources such as spring water in an effort to conserve biodiversity. Spring water discharged from quarrying and rain water is directed into our retention basin to minimize impact outside of the quarrying area. In some quarries we drill wells for domestic water and supply the water to local communities for everyday use. ● Greening Quarries We are continuing our efforts to restore greenery to the quarry slopes on step-like rock layers that are formed during the quarrying process. We undertake these efforts immediately after the slopes are made. We also plant vegetation in stockyards for excavated topsoil where no construction work is expected. Buko Mining Co., Ltd. located in Mount Buko in Chichibu City, Saitama Prefecture, conducts a tree planting campaign with partner companies to improve awareness of quarry development and the importance of greening. In our efforts to protect ecosystems we use as many types of native species as we can in the locations where we plant, which are usually mountainous. All of our quarries are still under our operation; however, once our work there is completed our plan is to restore the areas as close as possible to the original natural environment. ▶Key performance indicators (KPIs) in accordance with the Guidelines on Quarry Rehabilitation developed by the WBCSD-CSI are listed on page 66.
