Development and Expansion of Environmental Contribution Products

Environmental Contribution Products

To produce chemical and industrial products, we use natural resources, emit CO2, and generate waste, all of which impact the environment. However, considering the entire lifecycle of products from raw material extraction to final product disposal, there are cases where the presence of these chemical and industrial products helps reduce the environmental impact.
The Nippon Shokubai Group’s products are used throughout supply chains as well as in everyday products, the equipment used to produce those products, infrastructure, and elsewhere. Thus, we evaluate how our products contribute to reducing environmental impact.
Our internal certification committee examines checklists, numerical data, and other information to certify Environmental Contribution Products. In FY2022, we started to conduct a third-party review prior to examination by the internal certification committee, and to reflect the views and advice obtained from the review in examination materials. Five products were newly certified in FY2022.

Promoting the reduction of CO2 emissions throughout the entire lifecycle of products

We use the cLCA method to evaluate the best of our Environmental Contribution Products in terms of their contributions to reducing CO2 emissions.
The cLCA method is an evaluation method for calculating net contributions to CO2 emissions reduction; specifically, the difference between CO2 emissions throughout the lifecycle of a chemical product-based finished product and those of the finished product based on comparable products is considered to be the amount of additional emissions of the finished product if the constituent chemical product were not used.

Products expected to contribute to reducing CO2 emissions


4.05 million tons*1*2

  • Calculation of CO2 emissions avoided in one year when all apartments are built as long-lasting structures

We developed AQUAGUARD™ to limit cracking in concrete. Combining AQUAGUARD™ with high-performance AE water reducer should substantially prolong the useful lives of concrete structures.

*1 Assessment prerequisites
Service life: Assumed to be 100 years for long-lasting public housing and 50 years for ordinary public housing.
CO2 emissions associated with the manufacturing, use, and demolition of public housing evaluated based on the “LCA Guidelines for Buildings” issued by the Architectural Institute of Japan.
*2 The prediction value used for this evaluation was recalculated based on conditions in recent years.

(for damping materials)

310,000 tons*3

  • Calculation of CO2 emissions avoided when an application-type vibration-damping material is installed in all automobiles manufactured in one year

We developed an emulsion for vibration-damping coating to be applied to the lower surface of a vehicle body to suppress vibrations and noise from engines and road surfaces. Using vibration-damping coating should make automobiles lighter and conserve fuel.

*3 Assessment prerequisites
Vehicles to be driven 10,000 km per year for 10 years. Compared to vehicles with asphalt sheet as the vibration-damping material.


220,000 tons*4

  • Calculation of CO2 emissions avoided when ZIRCOSTAR™ is incorporated in all smartphones manufactured in one year

With its high optical properties, this product can be used as an optical material for plastic lenses, displays, and other components of mobile phones and smartphones, helping conserve the energy consumed by the displays of the devices and lengthen the battery life.

*4 Assessment prerequisites
According to the usage time described in the Carbon Footprint Product Category Rules, the product was evaluated as being in use for two years. A smartphone incorporating ZIRCOSTAR™ in the optical material was evaluated as achieving a 3.6% reduction in power consumption as an energy-efficiency benefit.


330,000 tons*5

  • Calculation of CO2 emissions avoided by reduction expected from all the UV curable inks produced in one year

Using VEEA™ as a UV-curing reactive diluent in eco-friendly ink removes the need to use volatile solvents and the equipment associated with them, saving energy and improving productivity.

*5 Assessment prerequisites
3.2 g of ink per m2 of full-size A-series paper (880 × 625 mm) on a four-color printer. Commercial offset and commercial UV printing presses were compared for evaluation.

AQUALIC™ H (for feed)

80,000 tons*6

  • Calculation of CO2 emissions avoided when all aquaculture feed produced in one year is replaced with moist pellets (MP)

With AQUALIC™ H as its binding agent, MP contains less fish meal—an ingredient that requires a lot of energy to source and dry—than dry pellets, helping reduce CO2 emissions in aquaculture business.

*6 Assessment prerequisites
Fish feed produced in all aquaculture business in Japan in one year.  Compared to dry pellets with no binding agents and high fish meal content.

sheets for solid
oxide fuel cells

Total: 5.96 million tons*7

  • (1) Calculation of CO2 emissions avoided when solid batteries are utilized as a regulated power supply for the use of renewable-energy-derived electricity supplied in one year (not including electricity for electric vehicles and the like)
  • (2) Calculation of CO2 emissions avoided from the use of fuel cells

IONEL™ and ICPDAP™/ICPSEB™ are used in storage batteries, which are expected to be used as regulating power sources to boost solar and wind power, which are the main sources of renewable energy but are characterized by widely fluctuating output. Additionally, solid oxide fuel cells are highly efficient at supplying power and heating water, contributing to reducing CO2 emissions.

*7 Assessment prerequisites
The CO2 reduction from using storage batteries is attributable to its regulation of fluctuations in power output for optimal economic efficiency in balancing supply and demand for electricity.
Due to the inability to forecast the supply of hydrogen, the CO2 reduction from using fuel cells is based on household fuel cells that generate electricity by modifying municipal gas. Compared to thermal power generation.

Aminoalcohol (for absorbent)
(Nippon Nyukazai Co., Ltd.)*8

5.5 million tons*9

  • Calculation of CO2 emissions avoided in one year when the CO2 emitted from thermal power plants is collected and stored using a chemical absorption technique

While renewable energy is increasingly being used, thermal power plants continue to operate to achieve stable power supply. Aminoalcohol contributes to CO2 emissions reduction because this product is used when these power plants trap CO2 from waste gas through a chemical absorption technique.

*8 A product of our Group company
*9 Assessment prerequisites
Aminoalcohol was used as an absorbing solution when CO2 was separated and collected, and the amount of energy required mainly for the separation and collection was evaluated. The comparison target was CO2 emissions without the separation or collection.
