Reducing Waste

In order to help realize a recycling-oriented society, the Lintec Group is working to reduce waste. It is also striving to save water, reuse waste water, while complying with the effluent control regulations and improving the quality of effluent generated.

Efforts for Zero Emissions*1

In fiscal 2018, the amount of waste generated, including manufacturing loss, at Lintec was 28,940 tons. The total waste output was 11,430 tons. Of this waste output, 7,110 tons were recycled by outside recycling companies and the remaining 4,320 tons were properly disposed of by waste disposal companies.
The final landfill disposal rate*2 for fiscal 2018 was 0.14%, achieving the target final landfill disposal rate of 1.0% or less. Lintec's target from fiscal 2018 to fiscal 2019 is a 0.1% reduction in the amount of waste generated, on a year-on-year basis.

  • *1 Zero emission: Lintec's standard is a final landfill disposal rate of one percent or less.
  • *2 The final landfill disposal rate is a value found using the following formula: Final landfill disposal rate = Final landfill disposal amount/Amount of waste generated × 100.

3R Efforts

Efforts to Reduce (reduce amount of waste)

At the Lintec Group, each plant works to increase production yield in order to reduce the generation of waste.
Also, production plans are carefully created to minimize waste of prepared chemical solutions and raw materials.

Efforts to Reuse (use repeatedly)

A large number of roll cores are used at Lintec, where most products are manufactured in rolls. Some of the cores shipped together with products are collected and reused in the manufacturing process.
Also, some of the wooden and plastic pallets used to ship products are collected and reused. If found unsuitable for reuse due to damage, wooden pallets are made into particleboard via an outsourced service while plastic pallets are repelletized.

Efforts to Recycle

The Lintec Group has continued to promote material recycling*1 and thermal recycling*2. The Tatsuno and Kumagaya plants collect waste that is unfit for material recycling, such as from polyethylene laminating paper and adhesive products, and incinerate it to recover process steam (thermal recycling). Each plant promotes resources conservation, working to increase production yield to reduce input resources and selling part of the generated waste to recycling companies as valuables.

  • *1 Material recycling: the recycling of waste as a raw material, such as using recovered paper as a raw material for recycled paper or turning empty cans into metal and PET bottles into synthetic fiber material, does not include thermal recycling.
  • *2 Thermal recycling: the recycling of waste by incinerating it to recover heat energy, as opposed to thermal disposal.

Driving Forward Initiatives for Proper Management of Waste

To manage waste and return items properly, instructions for classification are posted in a unified format at each collection point in the Tatsuno Plant. By individually specifying the color used for indicating the classification using RGB* color codes, and thereby making it easier to distinguish what can be disposed of based on the illustrated explanation, we strive to promote recycling, dispose of environmentally hazardous substances properly, and increase the awareness of employees. While we currently give instructions for classification into 55 categories in total, we hope to increase the number of categories and step up measures for proper management of waste.

  • *RGB: A technique to express various colors by combining red, green, and blue, which are the three primary colors of light.
