Material recycling! Contributing to a circular society with recycled PVC pipes.

The Value That Recycled PVC Pipes Bring to Society" ■ PVC is a material that can be recycled repeatedly, turning waste materials into new pipes. ■ 【Usage Scenarios】 * As beam sleeve material. * As underfloor drainage, ventilation, and air circulation pipes. * As civil engineering/agricultural rainwater collection and drainage pipes. etc. 【Benefits of Implementation】 * PVC is a material that can be recycled repeatedly, allowing PVC waste generated from construction and demolition sites to be transformed into new pipes, contributing to the improvement of the "mass waste" problem. * Compared to virgin material production, recycled materials clearly consume less energy, resulting in a significant reduction in CO₂ emissions. * Recycled materials are clearly less affected by fluctuations in crude oil market prices, and using them allows for a departure from dependence on crude oil and naphtha, enabling stable cost procurement. * The use of recycled materials leads to diversification in raw material procurement, ultimately contributing to improved supply stability of construction materials. * For more details, please request a catalog through "Contact Us" or view the PDF data via "Download.

Applications/Examples of results

<Other Uses> We have received great feedback, especially for use as sleeve material, and we propose its effectiveness in construction scenarios, even for non-JIS/JIS compliant products. - Drainage treatment for land development sites and exterior construction of buildings - Rainwater drainage within buildings/parking lots - Miscellaneous drainage related to agriculture - Ventilation ducts for buildings - Various types of formwork (sleeve material) - Short-term facilities such as temporary structures etc. ========================================== ■ We also offer innovative "labor-saving products" utilizing JIS standard PVC pipes for electrical equipment ■ 'Waterproof sleeve for underground exterior walls "Pipe-In-Sleeve" (abbreviated as PIS)' "Labor-saving construction for underground beam penetration! Enhancing the waterproof performance of buildings!" For underground exterior wall sections, waterproof treatment is applied in advance at the factory to the PVC sleeve and the surrounding space of the FEP, delivered as prefabricated units. No cumbersome work is required on-site; after installation, it essentially requires "only joint connections." Ensuring stable waterproofing! Achieving work efficiency and labor-saving, addressing water ingress and waterproofing. Please download from the related catalog.
