What is Bemliese™?

Sustainable, Now

Sustainability over the entire product cycle,
from sourcing to production to disposal.

Bemliese™ is made only in Japan, the result of all-natural materials formed into an outstanding product through superior processes and technologies that directly address environmental preservation.

The pristine setting of Nobeoka, Miyazaki Prefecture, the home of the Bemliese™ plant. Asahi Kasei has been producing Bemliese™ here since 1974, while continuing to implement procedures and policies that ensure the integrity of this environment.

From Nature, Back to Nature.

After use, returning to earth

Bemliese™ (110g/m2)

Because Bemliese™ comes from all-natural cotton linter, it has excellent biodegradability that lends to natural decomposition. If returned to earth, Bemliese™ will be broken down by microorganisms.

Biodegradability test, by mixing nonwoven fabric with compost and incubation in a dark place at a temperature of 28℃. Water content checked regularly. Adjusted as needed. Compost regularly stirred, with visual verification of the state of decomposition of nonwoven fabric.

In-house power generation infrastructure

The Bemliese™ plant in Nobeoka, Miyazaki Prefecture makes use of Asahi Kasei’s in-house power generation facilities. Renewable power sources such as hydroelectricity and biomasss supply up to 35 percent of the plant’s energy consumption*. Furthermore, overall energy conservation is enhanced by using exhaust heat, reducing heat loss and other measures. Concurrently, these activities augment the reduction of our carbon emissions.

Targeting zero waste material emissions

The elimination of waste material itself, repurposing/recycling and eventual landfill disposal is the basic process for zero emissions. At Asahi Kasei, a thorough recycling program is supported by such measures as repurposing the waste fiber from the Bemliese™ production process to fuel for energy generation and comprehensive reusing of waste from manufacturing plants. Along with other waste management initiatives, this has allowed us to achieve a nearly 100 percent (2016 data, 99.8%) zero emissions rate.

Social Contribution Through Business Activities

Throughout its global organization, Asahi Kasei is not solely in the business of filaments, it is involved in activities throughout the value chain, from base materials to final products. Bemliese™ is a subunit of the Bemberg™ business unit; Bemberg™ and Bemliese™ are both produced from pure cotton linter and share many of the attributes and manufacturing technology. In India, the Bemberg™ business unit has been a part of the Business Call to Action of the United Nations Development Programme since 2016. Asahi Kasei provides young employee nurturing and education support, as well as production enhancement support for small and medium-sized plants.

About Business Call to Action

Initiated in 2008, the Business Call to Action is led by governments and five development agencies including the United Nations Development Programme (the global development network of the United Nations), aiming at helping private enterprises achieve their sustainable development goals through business activities. As of May 2016, 137 companies from around the world have been involved in the Business Call to Action.
