Causes of land subsidence include brine pumping, groundwater extraction, natural consolidation of layer, and crustal movement.
We are tackling various challenges related to preventing land subsidence in order to achieve harmony with the environment and coexistence with the local community.
In order to prevent land subsidence caused by natural gas extraction, Chiba Prefecture and natural gas extraction companies have concluded an “Agreement on Prevention of Land Subsidence” and a “Detailed Agreement on Prevention of Land Subsidence,” which stipulates a limit on the amount of surface water discharge every five years.
The detailed agreement is revised every five years, and a new detailed agreement for five years from January 2021 was concluded on December 24, 2020.
Since the control of land subsidence is a common issue for the entire natural gas development industry, we are conducting joint research within the industry (Keiyo Natural Gas Council). Specifically, we are working on themes such as monitoring land subsidence using satellites and performing land subsidence prediction calculations associated with natural gas and brine development. Furthermore, we are conducting joint research with Japan Oil, Gas and Metals National Corporation (JOGMEC) and universities.
To promote appropriate energy conservation activities, we have established an “Energy Conservation Promotion Committee” and a “Energy Conservation Management Committee” consisting of representatives from each department as a subordinate organization to formulate and implement energy conservation measures.
The energy conservation efforts include the use of LEDs for exterior lighting on the premises, improvement of gas delivery methods, and reduction of compressor power consumption (equipment renewal). Comparing the unit energy consumption of the entire enterprise, the reason for the 100.5% deterioration compared to the previous year is thought to be due to a significant increase in operating hours at facilities processing raw materials with low iodine content (using natural gas).
With a five-year average unit energy consumption rate of 98.5% in FY2023 (results for the period from April 2022 to March 2023), we expect to be classified as S class in the business classification evaluation system. For the next fiscal year, we plan to reduce fuel consumption by updating boilers and improving gas delivery methods, and will continue our energy-saving activities.
In October 2020, we introduced the electronic manifest system for outsourcing industrial waste disposal. By digitizing manifests, the three parties involved in emission, collection, and disposal can always view and monitor the latest information, thereby preventing inappropriate manifest registration and reporting.
In addition, centrally managing waste generated from various parts of the company has enabled us to share information.
Compared to conventional paper manifests, not only has the clerical work become much more efficient, but also human errors such as omissions and incorrect entries have been reduced.
Iodine is a valuable resource. If iodine, which is collected and disposed of as "industrial waste," can be reused, an environmentally friendly recycling system can be created.
As a natural resource, iodine reserves are limited and need to be effectively utilized. Spent iodine in the pharmaceutical and medical fields, in the chemical industry, in electronic components, and in many other applications can be reused.
Our company is working on the recovery business of used iodine and recycling of valuable iodine to meet economic and environmental requirements and to make effective use of resources through comprehensive recovery technologies based on our unique know-how.
