ABSTRACT
The recycled plastic pin (RPP), which is commercially known as recycled plastic lumber, is manufactured by using post-consumer waste plastic and has been recommended as an acceptable material for use in the construction of docks, piers, bulkheads. RPPs require no maintenance and are resistant to moisture, corrosion, rot and insects. The use of RPPs helps to reduce the problems associated with the disposal of plastics. The manufacturing of recycled plastic lumber begins with the collection of the raw material, which is plastic waste. RPPs are manufactured by using commingled waste plastic that has been collected by municipal recycling programmes. At low temperatures, plastic is strong and brittle; however, with an increase in temperature, the plastic becomes weaker and more ductile. V. T. Breslin et al. conducted a study on the long-term engineering properties of plastic lumber manufactured by using post-consumer plastic. Recycled plastic lumber is a nearly isotropic material with considerable strength, durability and workability.
