Approach to Realizing Resource Recycling

Working to Reduce Waste and Increase Recycling Throughout Product Life Cycles

Management Approach

Basic ConceptPromoting resource recycling in aims of achieving a circular economy

SEKISUI CHEMICAL Group aims to realize a circular economy and a sustainable society in 2050. To achieve this long-term goal, we established a resource recycling policy and strategy in fiscal 2020.

In partnership with the supply chain, we minimize the consumption volume of virgin raw materials derived from fossil fuels. In addition, we are promoting recycling of resources through material circulation, aiming for a circular economy throughout our business. In order to achieve, we are intensifying our initiatives related to the following three points as our Group policy.

[Group Policy]

  • [1]
    Promote innovation that contributes to resource recycling
  • [2]
    Expand the use of non-fossil fuel sourced and recycled materials employed in operations
  • [3]
    Maximize recycling of waste discharged during product life cycles into materials

Efforts Toward Resource Recycling

For Vision 2030, SEKISUI CHEMICAL Group will strategically expand its business areas and double sales volume through social problem-solving, aiming to achieve a sustainable society and corporate growth. In these business areas, we believe plastics will continue to be an important material. Up until now, in the production process, we have continually made efforts year after year to reduce the amount of waste generated, using waste per unit of output as an indicator for these efforts. In addition, we have carried out internal recycling to reuse wood scraps and other waste materials produced and implemented processing for reuse of resources when disposing of materials as waste.

In our newly-determined resource recycling policy, we will expand the ratio of plastic materials we use comprised of bioplastics and other recycled materials which are not derived from fossil fuels. Regarding our production processes, we will promote internal recycling more than ever before, intensifying initiatives to minimize the waste products emitted from our production sites. In addition, in both the usage and collection stages, we will work on our product design and supply chain to ensure waste products can be disposed of with thorough separation and classification. In this way, we will promote initiatives to maximize reuse of material resources through the mechanical cycle, chemical cycle, and other cycles.

Within these life cycles, we believe that innovation at the product design stage is important for driving the promotion of resource circulation. By designing new products and revising the various processes for existing products, we are promoting initiatives for innovation that will accelerate resource circulation.

Promoting Construction Material Recycling

The housing industry is engaged in the efficient use and recycling of construction materials throughout. As a member of this industry, SEKISUI CHEMICAL Group also promotes recycling of construction waste produced when houses are demolished.a

Addressing the Issue of Plastic Pollution in Marine Environments

With regard to the waste generated by its production businesses, the SEKISUI CHEMICAL Group exchanges manifests with operators and confirms that disposal is undertaken in a sound and proper manner.

The impact of microplastics as a form of marine pollution has emerged as a significant environmental issue in recent years. The Group does not engage in the manufacture and sale of primary microplastics where use presupposes dissolution. However, we do recognize the possibility of deterioration and micro-reduction in the natural environment of plastic materials that go into the manufacture of the Group’s plastic processed goods and products, either during or after use, in the event that these are improperly discarded.

As the responsibility of a company engaged in the business of fabricating plastics, we are undertaking the following activities in order to workout fundamental solutions to this problem.

  • 1.
    Employee education
    In both the products we produce and our manufacturing processes, we must correctly recognize these types of issues, and develop human resources who are capable of finding a resolution. To this end, we engage in employee education while promoting environmental and social contribution activities.。
  • 2.
    Contributing to transformation within society by providing education and raising awareness
    To ensure the proper treatment of waste, SEKISUI CHEMICAL Group recognizes the importance of building social systems while promoting a shift in the awareness of each individual and undertaking education and training. The Group is therefore engaged in various collaborations between industry, government, and academia.
    In regard to the issue of marine plastics, SEKISUI CHEMICAL Group is currently a member of the Clean Ocean Materials Alliance (CLOMA) and a participant in the Japan Initiative for Marine Environment (JaIME). Every effort is being made to promote international collaboration, consider methods for resolving issues, and engage in a variety of activities, for example in the dissemination of educational information.
  • 3.
    Creating and expanding the use of products, technologies, and services that contribute to the realization of a recycling-based society and a circular economy
    SEKISUI CHEMICAL Group gas developed a technology that converts combustible waste, including marine plastics, into gas and then converts that gas into ethanol as a raw material for plastic using a microbial catalyst. Following a study at the test plant in the town of Yorii, Saitama Prefecture, we are now constructing a demonstration plant that will process one tenth of the volume of municipal solid waste at a standard-scale waste disposal facility (approx. 20 tons/day) in Kuji City, Iwate Prefecture. This plant is scheduled to go into operations in March 2022.

Promoting Packaging Material Reductions

SEKISUI CHEMICAL Group has long been an environmentally conscious company, and we are reducing packaging volumes, introducing reusable boxes*, and eliminating packaging wherever possible, among other initiatives. Our proactive efforts to reduce packaging since the early 2000s have enabled us to achieve results. We will continue these efforts in the future, taking further steps to reduce packaging waste.

As one initiative aimed at using less product packaging, we sell foldable shipping cartons and a range of plastic containers that help facilitate the implementation of returnable box systems.

  • Boxes that can be reused to ship materials, parts, and products between locations.
Major Initiatives

Converting External Wall Scraps into Raw Materials for Products

The Sekisui Board Co., Ltd. Gunma and Mizukuchi business sites, which produce Sekisui Heim external walls, generate scraps during their production processes. Along with making efforts to reduce the volume of scraps produced whenever possible, these companies are moving forward with in-house material recycling for any scraps that are ultimately generated.

The scraps generated during the production of products from the completed external walls are crushed and classified, after which the extracted wood chips and cement are used as recycled raw materials.
