Realization of a Resource Efficient Society
Together with our customers and society, Hitachi will do its utmost through its business operations to help
build a society that uses water and other resources efficiently. We will expand circulative uses of water byfurther advancing the entire range of water treatment technologies involved in water use from seawater
desalination and other forms of fresh water generation to sewage treatment.
We also aim to improve our usage efficiency of water and other resources by 50% compared to fiscal 2010
levels by fiscal 2050. To achieve this target, we will create products that last longer and use less resources,
make thoroughgoing efforts to collect and recycle used products, reduce the volume of water used in theproduction process such as through purification and reuse, and engage in other efforts.

Improving Usage Efficiency of Water and Other Resources
Water Conservation

Reduction in Water Usage per Unit

Hitachi uses water in such production processes as cleaning,cooling, and painting. To reduce water usage through greater
efficiency, we are enhancing our level of water management byinstalling flow meters at more locations, introducing wastewater
treatment devices to increase the use of recycled water, andupgrading water supply facilities at our business sites.
Different countries and regions are affected by water-related
issues in different ways, so we devise appropriate
countermeasures for each region. Our business sites in China,
India, and the Philippines, for example, are striving to reducethe volume of water used by strengthening measures against
water leakage.

Reducing Waste Volume
For fiscal 2016, we set a target of a 12% reduction (from a baseyear of fiscal 2005) for waste and valuables generated per unit,
bettering this by achieving a 13% reduction. Every business site isreducing waste through onsite recycling of byproducts and scrap
from the production process and efforts to curb use of packing
materials during transport. Under the Zero Emission initiative,
which seeks to minimize landfill disposal, 98 business sites
achieved their zero emission goal* as of fiscal 2016.

Creating a Resource Efficient Society Through Business
Water Solutions to Protect Global Water Resources
Water covers 70% of the earth’s surface, but only 0.01% of
it is potable. Demand for water, however, is on the rise
globally, with more than 40% of the world’s population
expected to face severe water shortages by 2050.
Hitachi has acquired an extensive record in the waterbusiness as it strives to become a comprehensive water
service provider. We have supplied equipment to around 700
water purification plants and 900 sewage treatment plants inJapan, and over 200 sites in some 40 countries and regions
around the world. We continue building on this experience toprovide a variety of water infrastructure globally.
We are currently moving forward on IoT-based,optimized, and highly efficient water business solution
offerings, including water supply and sewage systems andseawater desalination plants. For example, our energy-72
