Environmental Management in Production

In recent years, there has been growing interest in the environmental impact of materials, parts, and manufacturing processes. Our products make use of the characteristics of natural materials to manufacture products that can meet the demands for environmental consideration.
The photo shows the final condition of the biodegradation test, which was carried out for 5 months, after burying a paper (1 type) and our product (4 types of Vulcanized Fibre) in the soil for horticulture.
After 5 months, the paper remained almost unbroken meanwhile the four types of Vulcanized Fibre were broken into pieces.
Vulcanized Fibre is considered to corrode faster than paper because the main raw material is pure cellulose (with less additives).
