What is the XPR System?<\/div>\n\n\n\n
\n\n
\n\n
This resource recycling system manufactures raw materials and products by breaking down the crosslinks in cross-linked polyethylene (plasticization) to create new polyethylene.
\nCross-linked polyethylene is widely used in power cables and hot water pipes, but it is difficult to recycle and has traditionally been treated as fuel or industrial waste.
\nOhashi Co., Ltd. was selected for the Ministry of Economy, Trade and Industry’s “Sapioin (Strategic Core Technology Advancement Support Project)” and, together with Yamagata University and partner companies, developed the “XPR System,” which cuts the crosslinks in cross-linked polyethylene and restores it to its original state.
\nThis technology allows recycled materials to be used in our “Repy Board” product, improving its heat resistance.
\nThe “XPR System” does not emit CO2 and qualifies for the government’s “Project to Promote the Introduction of Advanced Resource Recycling Equipment for Building a Carbon-Free Society.” Furthermore, small and medium-sized businesses may be eligible for subsidies covering half of the installation costs.
\nPlease feel free to contact us regarding pellet sales and equipment installation.<\/div>\n\n\n\n
<\/div>\n
\nIn May 2024, it was registered with NETIS (Ministry of Land, Infrastructure, Transport and Tourism’s New Technology Information System).

Recycling of cross-linked polyethylene<\/div>
Pellets are produced using a manufacturing machine that uses the XPR system.
\nThe development of the manufacturing machine was funded by a subsidy from the Ministry of Economy, Trade and Industry (Sapoin), and we have obtained patents No. 6735885, “Method for regenerating polymer compounds,” and No. 7281860, “Method for producing polymer compounds.”<\/div><\/div>\n<\/div>\n\n\n

\nThe XPR system not only contributes to resource recycling and the creation of a decarbonized society, but also creates new materials that could not be created through chemical synthesis.
\nMateriaAluminization creates environmental businesses, and new functions further enhance value.<\/div>\n<\/div>\n\n
