High-performance, eco-friendly natural infill that carries the value of nature

Natural infill is made from naturally derived materials rather than chemical substances, making it an eco-friendly infill solution that is safe for people and the environment.
It effectively absorbs impact during walking and sports activities to reduce injury risk, helps mitigate temperature rise,
and minimizes odors and harmful-substance generation to provide a pleasant and healthy user environment.
As a fundamental alternative to environmental issues such as microplastics, it is a sustainable artificial turf infill applicable to schools, parks, sports facilities, and various public spaces.

Fired Mineral Ball
Performance created by nature,
safety completed by technology

Loess and zeolite are representative natural purification and adsorption materials. They do not generate microplastics even when rubbed or damaged, are effective in removing microplastics and harmful substances, and create a pleasant environment through temperature-reduction functionality. Used in its natural state without chemical substances, it is safe for spaces used by children and pets.

Fired mineral balls are completed in a hygienic and stable state through high-temperature firing at 1,000–1,200°C, removing foreign matter, residues, and bacteria. The firing process secures durability and strength suitable for sports facilities. After use, it is a 100% naturally returnable material.

High-Density
Loess-Coated Wood Fiber
A dual-structure material designed by nature

This high-density dual-structure material uses organic wood fiber as the core and coats the surface with inorganic loess to increase density. Because the entire material is composed of naturally derived components, it does not generate microplastics even under friction or breakage.

With excellent moisture absorption and release, the material provides outstanding temperature-reduction performance, creating a pleasant environment and helping reduce user injuries. It contains natural antibacterial components, is safe from heavy metals and harmful substances, and offers durability with strength suited to sports facilities.

Manufacturing Plant

100% Domestic Production

As a specialized company equipped
with one of Korea’s largest loess ball production facilities,
KUM Ryoung operates a reliable eco-friendly production system
that meets domestic environmental standards.

Natural loess balls are produced entirely in Korea,
from raw-material blending and firing to quality inspection.
Through an in-house manufacturing system rather than overseas outsourcing,
we minimize quality variation and consistently manage safety and performance.

Loess balls are a natural-material technology completed through high-temperature firing,
offering an eco-friendly environmental solution that addresses everything
from microplastics to temperature control.

Applications

Product Applications

Rich in natural minerals from loess, it provides excellent antibacterial and deodorizing effects.

    01 Eco-Friendly Children’s Playgrounds

    (Green Smart Schools, soccer fields, baseball fields, futsal courts,
    park golf courses, jokgu courts, gateball courts, and more)

    By installing natural infill with durability suitable for sports facilities, environmental issues such as microplastics can be prevented. The material adsorbs dust generated in activity spaces and contributes to improved respiratory conditions. Its strong temperature-reduction characteristics help moderate heat in spaces prone to high surface temperatures, maintain humidity, improve maintenance efficiency, and reduce risks such as burns and static electricity, creating a safer and more nature-friendly environment.

    02 Leisure and Community Spaces

    (Dog playground facilities and park rest areas)

    For dogs, playgrounds are essential spaces that support psychological stability and stress relief through active movement and exploration of various scents. As shared play spaces for people and dogs expand, it becomes important to apply natural infill materials that help reduce injury risk and surface temperature. For dogs sensitive to smell, the natural scent of natural materials can offer greater comfort than artificial materials, and because dogs are vulnerable to heat stress, eco-friendly materials with temperature-reduction functions are especially important to reduce the risk of burns from hot ground surfaces.
