Measures to Achieve Carbon Neutrality

Crasus Chemical is seriously committed to reducing CO₂ emissions.
When making a fresh start as Crasus Chemical, we newly set the CO₂ emissions reduction target of the company as follows: achieve a 30% reduction in 2035 relative to the 2020 level and achieve net zero emissions in 2050.
Toward 2035, we will implement measures with a focus on energy conservation. We will then work for the practical implementation of innovative technologies in society toward the achievement of net zero emissions in 2050. Furthermore, to achieve net zero emissions, we will conduct examinations to consider various possibilities beyond our own efforts, including collaboration with multiple companies across industries.
While striving for net zero emissions, we will also work for the creation of environment-friendly products, such as low CO₂-emission products made by using biomass-based and recycled materials as well as lighter plastic products, thereby contributing to reducing the use of plastic and other materials for environmental impact reduction.

Acquisition of ISCC PLUS Certification

Contributing to the achievement of carbon neutrality in 2050:
Replacing part of the raw materials used at the ethylene plant with biomass-based materials toward carbon neutrality

In July 2023, the Oita Complex obtained certification under the ISCC PLUS*¹ certification system, which is an international certification system for sustainable products. The acquisition of the ISCC PLUS certification has enabled us to attribute sustainability to products and derivatives containing sustainable biomass-based materials by adopting the mass balance method*² available under the certification system and sell them as sustainable products.
The Oita Complex used oil-based raw materials at the ethylene plant before June 2024, but has now started to use biomass-based materials as a partial replacement. These measures contribute to the practical use of sustainable materials in society and to the creation of a recycling-oriented society toward the achievement of carbon neutrality.
Crasus Chemical’s Oita Complex has made a pledge to meet the ISCC PLUS requirements in conformity with the latest ISCC rules.

*1 ISCC PLUS certification: This international certification system is implemented by International Sustainability and Carbon Certification (ISCC) in its capacity as a third-party organization. The system is designed to verify that the sustainability of biomass-based and recycled materials and the products made by using these materials is ensured and appropriately managed across a supply chain. Utilized as an effective certification system, it adopts the mass balance method to foster the use of biomass-based and recycled materials, particularly in supply chains with a complicated production process.

*2 Mass balance method: Manufacturers that make products by using both sustainable materials such as biomass-based and recycled materials and unsustainable materials can attribute sustainability to any one or more of the selected product items in proportion to the amount of sustainable materials input into the production process. By adopting this method, Crasus Chemical can make effective use of its existing manufacturing process to contribute to the expanded use of sustainable materials while maintaining the current product quality and performance levels. Moreover, consumers can also contribute to the creation of a sustainable society by purchasing environment-friendly products thus manufactured. The mass balance method is therefore expected to be more widely adopted across the chemical industry.

Energy Conservation Measures

• CO₂, which is a greenhouse gas, is generated mostly by the use of fossil fuel. Crasus Chemical uses fossil fuel as its energy source and aims to reduce the use of this fuel to reduce its CO₂ emissions. Moreover, we are promoting the remodeling of our equipment to be more energy efficient and energy-saving and reviewing our production process for energy conservation. When conducting regular repair work in 2022, we remodeled the ethylene plant’s decomposition gas compression system to reduce the amount of power used by the compressor, thereby achieving energy conservation. We will make efforts for further energy conservation and the improvement of energy intensity* .

  * Energy intensity: Calculated by dividing the amount of energy used for the manufacture of a given amount of products. A lower energy intensity rating implies higher energy efficiency and lesser environmental impact.

Measures to Reduce Greenhouse Gas Emissions

• We have been working to reduce the use of fossil fuels as raw materials, thereby reducing our CO₂ emissions. For chlorofluorocarbons (CFCs), which have a significant impact on global warming, we regularly carry out inspections on freezers, air conditioners and other products in which CFCs are used in our effort to manage emissions of these gases based on the Act on Rational Use and Appropriate Management of Fluorocarbons of Japan.
