Technical Document: Oil Pollution Control Technology for a Decarbonized Society

A Japanese-origin activated carbon purification method for a decarbonized society! Addressing oil contamination with the Smart Cap method, an activated carbon purification technology!

[New Oil Pollution Control Technology for a Decarbonized Society] ■ Following the Japanese government's "2050 Carbon Neutral (CN2050)" initiative in 2020, there has been a transformation in corporate awareness towards a decarbonized society. ■ The social implementation of a unique and highly effective "Negative Emission (NE) technology" that stores "biochar" in the ground and agricultural land, strongly promoting CN2050, has begun. ■ Since the postponement of establishing soil oil pollution concentration standards in the past, Japan's development of oil pollution purification technology has been in decline, peaking 20 years ago. ■ The "Activated Carbon Bioremediation Technology," which is also an NE technology, progresses with bioremediation after the sensory values of oil pollution are cleared early on. As a result, the challenge of determining the endpoint of purification, which was difficult with bioremediation, has been overcome, transforming it into a technology with excellent reliability for site management. ■ In Japan, there is a similar activated carbon purification technology known as the "Smart Cap" method, which has been proven to be applicable to oil pollution control as VOC purification technology. *For more details, please contact us or view the PDF download.

Non-destructive testing: Visible image method for crack investigation

Automatically extract "crack width" and "crack length"! No need to set up scaffolding for inspection!

Visible cracks and the occurrence of bulging are the first steps of deterioration and deformation. The digital imaging method automatically extracts crack width and length, and CAD output is also possible. Cracks are automatically extracted from the captured digital images. It can automatically extract "crack width" and "crack length." Since crack extraction is analyzed from the captured images, there is no need to set up scaffolding for inspection as long as the shooting location can be secured. 【Advantages】 ■ Safety (non-contact): Diagnosis can be performed from a safe location. ■ Record: Deterioration conditions can be visualized with thermal images, and image data can be saved for analysis. ■ Economic (short time): No need for temporary structures such as scaffolding or gondolas. *For more details, please contact us.

Line drone

New Standards for Safe Drone Operations

The use of drones for exterior wall inspections and infrared surveys is gaining attention as an efficient method that allows for inspections without the need for scaffolding. However, there is always a risk of crashes due to problems during flight, which poses a significant challenge for on-site safety managers. To thoroughly mitigate this risk, our company has implemented the "Line Drone" system. By using a dedicated line for the drone, we achieve a fail-safe mechanism that physically controls the flight range in the event of loss of control or runaway. ■ Benefits for Safety Managers - Provides peace of mind on-site: Instead of relying solely on software or sensors, we physically control the drone to minimize impact on people and the environment. - Improved efficiency and reliability of inspections: Safety measures allow for a smooth inspection flow, enabling you to trust the process. - Significant reduction in accident risks: Prevents unintended behaviors that could lead to runaway or crashes, enhancing on-site reliability and compliance with safety standards. We actively utilize the Line Drone to balance "efficiency of inspections" and "safety on-site." We prioritize safety management and provide reliable inspection services. *The Line Drone is a system developed by Seibu Construction Co., Ltd. and MAC Co., Ltd.

Investigation of tile and mortar peeling, lifting, cracking, etc.! Introducing the exterior wall inspection conducted by our company.

Even in durable reinforced concrete buildings, natural environmental factors such as daily wind, rain, light, and heat, as well as human usage conditions, can lead to aging and deterioration of the material's strength and performance over time. Therefore, our company conducts exterior wall surveys to gather basic data for repair work and to understand the current condition of the exterior walls. Using a tapping hammer, we tap the wall surface to check for any detachment based on the sound produced. In crack surveys, we measure the width and length of cracks using a crack scale. Additionally, we can investigate wall detachment using infrared thermography, which can be used in conjunction with tapping surveys. [Survey Items] - Detachment, bulging, and cracking of tiles and mortar - Deterioration of sealing and finishing materials *For more details, please refer to the related link page or feel free to contact us.
