Pitcher blocks, an eco-friendly packaging material, are in the spotlight these days when fine dust is severe. As fine dust reduction measures are implemented day after day, the pitcher block is drawing more attention as awareness of "re-scattering dust" on the road increases. Re-scattering dust refers to dust that rises back into the air and flies as a car passes. Experts argue that this threatens human health.


On the 6th, the Ministry of Environment announced that it would concentrate its capabilities in cooperation with eight watersheds, local environmental agencies, and local governments across the country. First Vice Minister of Land, Infrastructure and Transport Park Sun-ho visited the Korea Expressway Corporation's transportation center and ordered, "Please recognize the situation in which fine dust emergency reduction measures are being implemented for six consecutive days as a disaster and respond thoroughly to protect the health of the people."

Already, the Korea Environment Corporation is operating a "road scattering dust management system" for the metropolitan area. The measurement management system, which consists of a mobile measurement vehicle and a data transmission and storage system, quickly and accurately measures the concentration of particulate matter with an aerodynamic particle diameter of 10이하 or less every second and shares the measurement results with local governments.

For the first time in Korea, buses and other vehicles are passing through the road in front of Jochiwon Station, where pitching blocks are laid on four-lane roads.

Through this system, it was found that fine dust generated on some roads in the metropolitan area was more than five times the level of "very bad" (201201/이상 or more). Road fine dust, also called "road re-scattering dust," is dust that occurs when asphalt, tires, and brakes are worn out. The Korea Environment Corporation says it is more harmful to the human body and has a direct effect on pedestrians than ordinary fine dust.

Against this backdrop, eco-friendly pitcher block pavement constructed on a 3-90m round-trip four-lane 60km/h road in front of Jochiwon Station in Sejong City is drawing attention. It is known for the first time in Korea and abroad that blocks have been paved on major roads where buses pass.

On the 7th, the reporter visited the road site in front of Jochiwon Station, where a year and four months have passed since its construction, but no abnormal signs such as damage have been found. The move is aimed at removing the four-lane asphalt pavement and visually confirming that the roads where buses travel have been paved with blocks.

In fact, city buses and cars were running continuously, and citizens were crossing the street freely. There was a separate crossing, but people seemed to recognize it as a sidewalk, and the vehicles were generally slowing down even though it was a stark road. The road, which opened on November 1, 2017, is known to have been created as an eco-friendly block road by the decision of the "Jochiwon Central Road Prosperity Association."


Chairman Byun Young-il said, "It's not hot in summer because of the lack of geothermal heat." "I couldn't stand when it was asphalt, but it's cool," he said. "It's good that the water is drained well and the cars aren't speeding because it's a block."

The water permeable block on this road is an eco-friendly block packaging material called a hole block and has been confirmed as a patented product developed by Daeil Tech, which has factories in Jincheon-gun and Eumseong-gun, Chungcheongbuk-do. According to the company's data, this water permeable block, which was developed as a new product in 2009, has advantages such as △ easy repair for partial damage △ vehicle speed control (safety) △ waterlogging prevention △ urban heat island phenomenon mitigation △ environmental pollution △ groundwater security.

However, despite these advantages, existing permeable blocks have disadvantages such as severe deviation in strength between blocks, reduced durability, pore blockage, color-side peeling, and horizontal movement. In order to compensate for these shortcomings while maintaining its advantages, the company has developed a patented product that can achieve △strength enhancement and uniformity △ minimize pore blockage △ reduce peeling and horizontal movement.

Accordingly, patented products are evaluated to have achieved △ a simple manufacturing process of compression molding △ a low unit price mass production △ a minimum and optimal manufacturing process △ an improvement in production speed.

Daeil Tech announced on the 3rd of next month that it will hold a completion ceremony for its second plant in Eumseong Production Industrial Complex and begin a full-scale mass production system. In particular, it was confirmed that the company's pitching block products showed superior results in all eight areas of test evaluation in research results that have not yet been officially announced.

Last year, related public institutions entrusted the Block Association with the "Quality and Publicity Test Service of Water Pitcher Block Packaging" for products from nine companies in the market to conduct research on △ quality test of blocks △ shape and dimensions △ surface layer (color layer) △ permeability coefficient △ wear resistance △ freezing resistance of pitcher blocks.

CEO Baek Won-ok said, "It has become a world where human development activities cannot be prevented," adding, "We are making eco-friendly products with high intensity while rainwater and dust permeate so that they can coexist with the Earth." He said he is developing block laying equipment and cleaning equipment for the roadway, which has more than 10 patents. After investing 10 billion won on a 20,000㎡ site in the Eumseong Saenggeuk Industrial Complex to build a second plant, he announced that he plans to invest an additional 5 billion won in the future.

Meanwhile, Daeil Tech built five locations in front of Jochiwon Station, Ulsan Jangsaengpo Ring Road, Osan City Cheongjogyo Bridge, and Gunpo City Central Park, Incheon Veterans Hospital, Suanbo Park Road, Seoul Land's old facilities, Cheongju SB Plaza, Seoul Hwagok Elementary School's road and sidewalk, and hundreds of tourism blocks.
