What does "returning to nature" greening aimed at by Rontai mean?

Early greening for disaster recovery - Achieving speedy construction.

The "Ronkette DX" by Rontai is a vegetation mat that enables stable plant growth on slopes where root extension is difficult, such as soft rock and hard soil, while preventing surface erosion. This product allows for the selection of the number of base material bags to be attached according to soil hardness and slope, making it adaptable to different construction conditions at the same site! Additionally, it is equipped with a highly water-retentive soil amendment that protects seeds from drying out like a cover soil, improving plant germination and growth. 【Features】 ■ Achieves early greening ideal for disaster recovery ■ Can be installed in narrow spaces ■ Initial erosion prevention effect ■ Compatible with wire mesh products *For more details, please refer to the catalog or feel free to contact us.

Early greening is possible! Two products that are active in disaster recovery for slopes. Case studies are presented.

Our company offers products that are effective for "early greening and erosion prevention" at restoration sites where slopes have collapsed due to natural disasters. The vegetation mat for cutting, "Ronquet DX," promotes seed germination and growth through high water retention and nutrient-holding soil amendments, achieving early greening. Additionally, a special polyester non-woven fabric prevents surface erosion and sediment runoff! The vegetation bag "Green Bag" is covered with seeds and fertilizers on all sides, allowing for installation regardless of direction or orientation. Simply fill and install with locally generated soil to achieve greening, and it is also used for backfilling collapsed slope areas. Ronquet DX - Enables speedy construction as no construction machinery is required. - Offers four grades to choose from based on soil type and conditions. - Compatible with wire mesh products. Green Bag - Effective for protecting structures and preventing sediment runoff behind retaining walls. - Can achieve greening even at the ends of bags in favorable moisture conditions. - Fully equipped with seeds and fertilizers. *You can view materials with construction examples from the "Download" section.

◇Active in disaster recovery sites◇For early greening◇

Ronquet DX is a vegetation mat for soft rock I and hard soil. The special non-woven fabric made of polyester attached to the product alleviates the impact of raindrops on slopes over a long period, while the substrate bag reduces the flow velocity of rainwater on the slope surface. It is effective for sites where early erosion prevention on slopes is necessary! You can freely choose from four types of grades according to soil type, soil hardness, and slope gradient, so even if there are different site conditions within the same location, you can use products from the same series. *Please download the construction case collection from the form below. 【Features】 ◆ Disaster recovery through early greening ◆ Achieves speedy construction ◆ Initial erosion prevention effect ◆ Compatible with various site conditions -------------------------------------------------------------------------------- Rontai offers free slope surveys at construction sites.

Adopted by major semiconductor manufacturers. Over 10,000 copies produced annually. This high-quality cleanroom notebook (dust-free paper notebook) has been loved for many years in "Silicon Island Kyushu," where some of the world's leading semiconductor manufacturing companies are located. It uses Sakurai Co., Ltd.'s "Staclean RV (recyclable dust-free paper)" and is designed for professional use, minimizing dust generation to the utmost. It supports "writing" in semiconductor factories, precision equipment manufacturing sites, and medical environments. [Main adopting companies: SCK, JASM, RSMC, and many others] ■ Three reasons why Yoneura Printing's "Cleanroom Notebook" is chosen: - Proven track record: Adopted by multiple major semiconductor companies in Kyushu, with an annual production and sales record of over 10,000 copies. - Use of the highest quality dust-free paper: The main paper uses "Staclean RV Violet 72g," and the cover uses "Clean Paper RC 175g," achieving low dust generation. - Size options tailored to the workplace: A lineup ranging from standard A4 and B5 sizes to convenient mini sizes that fit into cleanroom pockets. ■ Product lineup: - Clean Notebook A4 @400～ - Clean Notebook B5 @380～ - Clean Pocket (mini size) @225～

PERI products are used at construction sites around the world. This time, we would like to introduce the construction site 'Rotterdam Capacity Growth (RDCG)' in Rotterdam, Netherlands. PERI is supporting the expansion of one of Europe's largest biofuel refineries by providing innovative scaffolding solutions. This helps meet Europe's high safety standards, achieve efficient processes, and significantly contribute to the decarbonization of air transport. As part of the Rotterdam Capacity Growth (RDCG) project, one of Europe's largest biofuel refineries is under construction. This will increase the annual production capacity of biofuels from 1.4 million tons to 2.7 million tons. PERI products: 1. PERI UP (modular scaffolding) PERI Japan Co., Ltd.

In preparation for this summer's extreme heat, we have completed a "Heatwave Countermeasure Catalog" that will help improve the working environment in the manufacturing and logistics industries. The catalog includes a wide range of products for facility improvements, such as fireproof certified heat-shielding sheets that cut radiant heat by 97%, heat-shielding curtains, roof and window countermeasure products, and fans suitable for large spaces, as well as black globe thermometers that can measure WBGT, wearable alert bands, mobile cooling shelters, and fan-equipped work clothing. We have consolidated measures for "building countermeasures," "work space countermeasures," and "personal countermeasures" into one volume. It can also be used as reference material for discussions in safety and health committees. Please take a look at the specific measures that simultaneously achieve heat countermeasures and energy conservation/CO₂ reduction.

We have recently started a demonstration experiment aimed at addressing antibiotic-resistant bacteria in dairy farming. Utilizing compost environments, we will examine the impact of using our technology-based aqueous solutions on microbial dynamics. This experiment is being conducted with field cooperation, aiming to establish a new approach that contributes to the realization of a sustainable livestock environment and the reduction of antibiotic usage. In this trial, we will set up a spray group (Group H) and a non-spray group (Group C), and will conduct a time-series comparison before spraying, immediately after spraying, and at 1, 3, 7, 14, 28, and 42 days, as well as at the maturation stage. We will perform sampling from the upper, middle, and lower layers of the compost at a depth of 10 cm, while simultaneously collecting temperature logs (external temperature and two internal compost temperatures) to analyze microbial changes and fermentation status from multiple angles. Based on scientific data, we will pursue a balance between safety and effectiveness, and work towards contributing to the livestock industry.
