IntegriTies? are composite railway ties produced from hard-to-recycle plastics sourced from material recovery facilities. IntegriCo's patented manufacturing process retains the qualities of plastic that make it a strong material while also permitting the use of unwashed plastics previously destined for landfills, company officials said in an email. The manufacturing method produces ties via a low-heat process. The resulting composite tie lasts up to four times longer than ties made from wood or concrete, IntegriCo officials said. The ties can be used for a variety of applications - from Class Ⅰ heavy-axle loads to the caustic environment of an industrial processing plant. In Class Ⅰ applications, the ties offer strong spike retention and high compression strength; are immune to insect infestation, fungus and mildew; have high electrical impedance and a longer life cycle in harsh climates; are resistant to rail plate cutting; and can be installed with existing equipment alongside wood ties, company officials said.
