Efficient Use of Resources (Resource Recycling)

Basic Policy

Economic growth in emerging countries is intensifying the need to conserve nonrenewable resources and prevent pollution. Iron can easily be separated and is thus highly recyclable. It can be recycled and reused to make other steel products infinite times (closed-loop recycling). The JFE Group is leveraging each Group company’s strengths to enhance resource recycling through recycling co-products from iron and steelmaking, reducing waste at construction sites, and promoting the global recycling of steel scrap.

Promoting Resource Recycling

Each operating company of the JFE Group carries out resource recycling suited to its particular business. We continue to pursue increasingly efficient uses of resources in both the production and product/service phases of its businesses, including steel scrap recycling, biomass fuel production and waste-to-energy power generation.

Reducing Generation and Emission of Co-products and Reusing Co-products

JFE Steel

JFE Steel carefully controls the generation and emission of iron and steelmaking slag (coproduct), iron dust from blast furnaces and converters, sludge from water treatment facilities, and other coproducts. The target rate for recycling is 99% or more. Dust and sludge with high iron content are recycled as raw materials for steelmaking. Iron and steelmaking slag is effectively recycled for reuse in cement and other construction materials. We are also promoting their use as environment recovery material such as Marine Stone™, which works effectively as a base for the adhesion of organisms and for improving the marine environment. As a result of such efforts, the company achieved a 99.7% recycling rate for slag, dust, and sludge in FY2019, consistently maintaining the target of 99% or higher.

Promoting Recycling

JFE Engineering

Most of JFE Engineering’s waste is either rubble and sludge discharged from construction sites or industrial waste discharged by the Tsurumi and Tsu works. We strive to reduce industrial waste and promote resource recycling through various measures, which include setting environmental goals for recycling rates and properly separating the waste on-site before sending it to disposal companies known for achieving high recycling rates.

The City of Yokohama has named JFE Engineering’s Yokohama head office as a Workplace with Excellent 3R Activities every year since FY2012 to recognize its waste reduction, reuse, and recycling activities. The JFE Engineering Group is also working to realize a recycling-oriented society through its PET bottle and food waste recycling initiatives.

Development and Provision of Eco-friendly Processes and Products

Resource Recycling Solutions

The JFE Group is involved in establishing a recycling oriented society through a variety of initiatives. Steelworks promotes the efficient use of raw materials, water, and other resources in the process of iron and steelmaking in addition to encouraging the application of recycled resources such as used plastics for blast furnaces. Moreover, we are striving to more efficiently use co-products generated in the iron and steelmaking process through initiatives such as the international recycling of steel scrap.

In the engineering field, in addition to constructing and providing customers with waste incineration plants and plants for treating sludge, we are developing a waste recycling business and an energy supply business to offer resource recycling solutions.
