Basic Approach

The recoverable reserves of aluminum, the primary raw material used by the UACJ Group, are in greater abundance, and will be recoverable for a longer period, than those of other metals. We still believe, however, that promoting recycling and reuse is important for passing resources on to future generations. In addition to conventional waste recycling, therefore, we are also vigorously supporting closed recycling* for items such as aluminum cans and printing plates, and striving to reduce waste. In pursuit of our environmental objective of realizing a recycling-oriented society, we will work continuously to reduce our generation of industrial waste per unit of production and achieve zero emissions.

* Closed recycling is the recycling of aluminum used in a specific type of product into raw material to produce the same type of product.

Fiscal 2017 Results

The UACJ Group is moving forward with efforts to reduce industrial waste and pursuing activities aimed at achieving zero emissions.

For us, “zero emissions” means that direct landfill waste comprises less than 1% of all industrial waste generated. For fiscal 2017, we achieved zero emissions with a direct landfill waste ratio of 0.07%. Going forward, we will work to maintain zero emissions by separating industrial waste and recycling.

In fiscal 2017, the total amount of industrial waste generated at our principal business locations fell by 4.1% compared to fiscal 2016. Going forward, we will continue to reduce industrial waste, recycle, and turn waste into substances of value.

Industrial Waste Subcommittee

At UACJ, the Industrial Waste Subcommittee has been established mainly with representatives of business locations generating significant amounts of industrial waste. The subcommittee meets regularly to promote reductions and proper processing of industrial waste by establishing a common understanding of separation and processing information, and by examining and promoting improvements in separation practices, and establishing a common understanding of reduction measures, at individual business locations.

Promoting Recycling of Aluminum Cans

Aluminum is light-weight, does not rust, conveys heat well, and is highly recyclable*1. Given the outstanding qualities of the metal from which they are made, aluminum cans are recycled at a rate*2 of 92% (fiscal 2017). By having each of its works purchase used aluminum cans, the UACJ Group is supporting aluminum can recycling activities and contributing to the creation of a recycling-oriented society.

  • *1 Recycling aluminum requires only about 3% of the amount of energy needed to produce new aluminum from bauxite.
  • *2 Aluminum cans collected and recycled in Japan (including for export purposes) as a percent of all aluminum cans purchased by consumers in Japan.

Effective Use of Water Resources

Approximately 70% of the earth’s surface is covered by water, but only about 0.01% of all of the earth’s water is fresh water - water that can be easily used by humans.

From a global perspective, these precious freshwater resources are recyclable. With uneven distribution, however, there are already countries and regions facing serious risks of water shortages.

The UACJ Group strives to use and manage water resources effectively based on its keen awareness of these circumstances. Each of our business locations tracks its water usage by water source, and manages wastewater discharges by the waterway into which the discharges are made. Data on our water usage has been tallied and is included in the material balance information presented in the Business Activities and Environmental Impacts section.
