Chemical factory	CO2 emissions reduction: 1,943 tons/year	The factory was able to reduce its use of boiler fuel by replacing its existing boiler with a highly energy-efficient model capable of continuously controlling the use of fuel based on the steam pressure.
Power generation plant	Waste reduction: 314 tons/year	The plant decontaminates liquid containing high concentrations of chemical substances from the chemical cleaning of steam pipes by the use of a wastewater treatment system. The highly concentrated wastewater is heated to reduce the amount of waste.
General households	CO2 emissions reduction: 25,808 tons/year	General households were able to reduce use of tap water and gas for heating by installing water-saving shower heads developed and sold by Kurita to faucets.
Semiconductor and LCD plant	Waste reduction: 562 tons/year	The plant removed chemical substances and stains attached to the components of its semiconductor and LCD manufacturing equipment, thereby making prolonging their lives and reducing the generation of waste.
Textile dyeing factory	Treatment of wastewater: 20,000 m3/year	The factory stabilized the treatment of wastewater by introducing a coagulation treatment system for highly concentrated wastewater and discontinuing mixed treatment of low- and high-concentration wastewater.
Semiconductor plant	CO2 emissions reduction: 49 tons/year	The plant improved its water recovery rate and saved more water by applying scale inhibitor to the RO membrane equipment used to recover wastewater.
Shielded tunnel digging site	CO2 emissions reduction: 105 tons	At the site, dehydration agent was used to shorten the time required to dehydrate mud water generated from shielded tunnel digging, which in turn reduced the use of electricity used for the dehydration equipment.
Beverage factory	CO2 emissions reduction: 62 tons/year	The factory attached a heat-insulating cover to steam pipes to reduce heat released from the pipes, thereby decreasing the use of boiler fuel.
Food factory	CO2 emissions reduction: 68 tons/year	The factory introduced a system to recover and reuse wastewater from the product container cleansing process, thereby reducing the use of clean water and saving water resources.
Chemical factory	Contaminated soil remediation: 224,000m3	The factory removed hazardous substances contained in groundwater by the use of a treatment system newly developed in consideration of the properties of the contaminants, thereby purifying the contaminated groundwater.

Inorganic coagulant	A chemical agent that collects suspended matter in water and coagulates them into larger particles.
Organic coagulant	A chemical agent that can coagulate a greater volume of suspended matter in water than inorganic coagulant.
Heat pump	Equipment that exchanges heat with surrounding air and water by using the vaporization heat and condensation heat from heating media
COP	COP stands for coefficient of performance and indicates energy consumption efficiency. For example, COP 8.4 indicates that 8.4 kWh of heat can be generated by the use of 1 kWh of electricity.
Demineralizer	Equipment to demineralize water by removing suspended matter, salts, and organic matter contained in the water.
Concentrated water	Water wasted from the demineralization process, which contains impurities at high concentrations.
Sludge	Sludge refers to the pollutants in wastewater that have precipitated or floated up to the surface of the water to form a muddy film. Generally, sludge is dehydrated to reduce its volume and weight and then disposed of as waste.
Anaerobic treatment	Method to treat organic matter in wastewater by the use of microorganisms, which decompose organic matter into methane and CO2 under oxygen-free conditions.
Aerobic treatment	In contrast to anaerobic treatment, microorganisms decompose organic matter into water and CO2 with the help of oxygen.
LTD value	LTD stands for leaving temperature difference, which is an indicator that shows differences in temperature between refrigerant and the cooling water used to cool the refrigerant.
High-polymer dehydration agent	A chemical agent that fosters dehydration by separating moist solids contained in sludge into solids and water.
Ion-exchange resin	A type of synthetic resin that exchanges ions in water and its own ions, which is regenerated for reuse when there are no more ions to be exchanged.
Biogas	Gas generated when organic matters are decomposed by microorganisms.
ORP value	ORP stands for oxidation-reduction potential, which can be used as an indicator of the amount of microorganisms in water.
J-VER	A scheme implemented by the Ministry of the Environment, in which the amounts of greenhouse gas emissions reduced and absorbed through the projects implemented within Japan under the scheme are certified as credits that can be traded for carbon offsets.
Environmental ordinance	Environmental ordinance issued by the Tokyo metropolitan government to ensure the health and safety of citizens. The Tokyo metropolitan government became the first local government to impose CO2 emission reduction duties on local large business installations.
ESCO business	An energy service company (ESCO) provides customers with comprehensive energy conservation services and accepts a part of the savings achieved through the utilization of the services as compensation.
Blow water released from the cooling tower	Water is regularly released from the cleaning tower to maintain the cooling water quality.
