Start of the Study on Collaboration for Promotion of Gasification
Chemical Recycling of Plastic Waste
JGC Corporation
Ebara Environmental Plant Co., Ltd.
Ube Industries, Ltd.
Showa Denko K.K.
JGC Corporation, Ebara Environmental Plant Co., Ltd., Ube Industries, Ltd., andShowa Denko K.K. announced today that they started a study of collaboration for anEngineering, Procurement and Construction (hereinafter, “EPC”) business for plastic
waste gasification facilities utilizing the Ebara Ube Process (hereinafter, “EUP”)
following conclusion of a non-disclosure agreement on July 31, 2019.
1. Aim of Promoting Gasification Chemical Recycling of Plastic Waste
Promotion of plastic waste recycling has become a global issue, as seen in the ocean
microplastic problem. While Japan’s plastic recycling ratio is 86%, only 13.5% of theplastics waste are recycled as resources and the rest is exported to other countries orthermally recycled (fiscal 2017)*. Furthermore, establishment of resource recycling
systems is urgently needed in Japan and other countries amid tightening regulations forsolid waste import in China and Southeast Asian countries.
Gasification chemical recycling of plastic waste is capable of decomposing a mixture ofvarious kinds of plastics and impurities, which presents difficulties for other recycling
methods, into the molecular level and regenerating various chemical materials. It should
contribute to substantial improvement of the recycling ratio.
2. Ebara Ube Process (EUP)The EUP, which was developed by EBARA CORPORATION (transferred this businessto Ebara Environmental Plant in 2009) and Ube Industries in 2000, is a process that
*Source: “Plastic Products, Plastic Waste and Resource Recovery [2017]” (Plastic Waste Management Institute)gasifies plastic waste using partial oxidation with oxygen and steam, and producessynthesis gases that can be utilized in synthesis of ammonia, olefins, and otherchemicals.
A gasification facility steadily operating at Showa Denko’s Kawasaki Plant (annual
plastic waste processing capability: approximately 70,000 tons) since 2003 applies EUP.
This is the only technology for gasification chemical recycling in the world with along-term track record of commercial operation.
3. Plans
The four companies (JGC, Ebara Environmental Plant, Ube Industries, and ShowaDenko) aim to conclude an EUP licensing contract within the year, and then actively
implement sales efforts for gasification facilities for plastic waste adopting EUP in
Japan and other countries and conduct EPC activities. They also intend to promote thespread of gasification chemical recycling and use of recycling in Japan and othercountries via proposals for chemical production facilities utilizing ammonia, olefins,and other chemicals made from facilities which adopt EUP.

JGC Corporation
As an engineering company, JGC has accumulated gasification-related engineering
technologies by handling many plant facility construction projects that adopt
gasification processes, including overall management for construction of the firstcommercial Integrated Gasification Combined Cycle (IGCC) plant in Japan that wascompleted in 2003.
JGC hopes to make proposals that contribute to enhanced business value for recycledmaterial production and utilization firms and implement EPC for related facilities byapplying its accumulated gasification process engineering technologies and advanced
EPC project management capabilities through this collaboration.

Ebara Environmental Plant Co., Ltd.
Ebara Environmental Plant has accumulated extensive technology information
related to low-temperature gasification equipment used in the gasification system, themain characteristic of EUP technology, based on its proprietary fluidized bed
technology. EUP technology, which was commercialized jointly with Ube Industries,
extracts gases with value as feedstock from combustible materials incinerated in pastyears.
It hopes to contribute to realization of a sustainable society by expanding gasification
technology in society through this collaboration.
Ube Industries, Ltd.
Ube Industries, Ltd. has accumulated extensive technology information related tohigh-temperature gasification equipment used in the gasification system, the maincharacteristic of EUP technology. Knowhow obtained through operation of ademonstration gasification facility (annual plastic waste processing capacity: 30,000tons) built in Ube city was applied to the commercial facility at Showa Denko’s
Kawasaki Plant.
Ube Industries hopes to contribute to global environmental conservation anddevelopment of a sustainable recycling society by promoting wider use of plastic
waste gasification through this collaboration.
Showa Denko K.K.

Since 2003, Showa Denko has been operating a business that effectively utilizes
hydrogen and carbon monoxide obtained from plastic waste using a EUP-based
gasification facility as raw materials to produce ammonia and carbon dioxide products,
such as liquefied carbon dioxide and dry ice. It possesses technologies and operational
knowhow for stable production over a lengthy period under a condition in which
different kinds of plastic waste and impurities including metal are input into thegasification facility as raw materials.
Showa Denko hopes to contribute to the realization of a society where affluence andsustainability are harmonized by promoting chemical recycling of plastic waste andresource recovery through this collaboration.
