Environmental Approaches

Black pellets

We are developing a supply business of black pellets (woody biomass) that are semi-carbonized rubber wood chips, which can be co-fired with coal. We believe that co-firing biomass in coal-fired power is an effective CO2 reduction measure and a real solution to realizing an energy mix.

Background of the approach Compared to other power sources, coal-fired power generation has a higher CO2 emission per kWh, so the aim is to reduce the CO2 emissions by co-firing with biomass fuel.
What is biomass? Organic resources derived from animals and plants (excluding fossil resources), which absorb CO2 by photosynthesis during their growth process, so that it has a characteristic called carbon neutral that does not increase CO2 in the air even if it is burned.
Business progress In Thailand, we are working with local partners to manufacture samples and accumulate manufacturing know-how using demo plants, while also providing information to customers and preparing for the launch of commercial plants.

ULTY-V plus

The coal fired boiler control optimization system “ULTY-V plus” performs a series of control processes “measurement”, “analysis”, and “judgment” in a self-contained manner by using AI (artificial intelligence) in order to achieve the optimal operation of coal boilers used in power plants and factories. This system reduces CO2 emissions as well as fuel consumption, and is sold to China and Taiwan besides Japan.

How it works ULTY-V plus is connected to the boiler control system and corrected with a control program equipped with AI function to control fuel flow.
Effect Coal consumption (CO2 emissions) is reduced by 0.5 to 1.5%.
Sales destinations In addition to delivering to domestic electric power companies and large-scale factories, we are also selling to China, Taiwan, etc., and expanding the sales area further in the future.

Development of carbon recycling technology

Our Company, Ube Industries, Ltd., and NIKKI Group obtained the participation of multiple universities and set up a study group for developing new technologies that utilize industrial waste containing a lot of calcium and the like and convert CO2 emitted from power plants and factories into resources.

Features Since CO2 reacts spontaneously with calcium, magnesium, etc., no introduction of hydrogen or new energy is required.
Schedule for practical use FY2019 - FY2021 Leading research
FY2022 - FY2014 Demonstration test
FY2015 - Actual machine test
Topics In September 2019, the first international conference for the realization of “Carbon Recycling” was held in Tokyo, attended by first-tier officials from industry, academia, and government from around the world, and is expected to contribute to solving climate change problems. Among the speeches by the Minister of Economy, Trade and Industry as well as ministers and experts from each country, the Deputy Director of our Coal and Environmental Research Laboratory explained this approach and attracted high interest from visitors.

From mining operations to rehabilitation of mined sites in consideration of environmental conservation

In the mine, we are striving for environmentally friendly operations. While continuing to monitor dust, noise, vibration, water, greenhouse gases, etc., we are confirming the impact of the mine’s operations on the local community and working to minimize it.
In addition, after the mining has been completed, the mined site is backfilled and levelled, and then replanted and rehabilitated back to its original form. In this way, we are working to reduce the impact on biodiversity and maintain/improve the natural environment.

The course of rehabilitation

Challenge to renewable energy business utilizing mining infrastructures

We will actively work to create environmental businesses utilizing mining infrastructure in order to pursue the possibility of converting coal mines into a base contributing to the global environment.

Solar power
(Australia)
We are considering a business utilizing idle lands of mines and transmission lines to generate solar power and supply electricity to mines and local areas.
Pumped-up hydroelectric power generation
(Australia Muswellbrook Mine)
We are considering a business to supply electricity to local areas in such a way that the mined site is diverted into a reservoir, from which water is pumped up with inexpensive renewable energy power at times when demand is low, such as at night, to generate hydropower during demand hours such as morning and evening.
Biomass fuel
(Australia and Indonesia)
We are cultivating raw materials suitable for pellet production near mines, and are considering using existing infrastructure for producing and transporting biomass fuel.
