AB  - Plastics, which majorly consist of polypropylene (PP), polyethylene (linear 
      low-density polyethylene (LLDPE), low-density polyethylene (LDPE) and 
      high-density polyethylene (HDPE)), polystyrene (PS), polyvinyl chloride (PVC), 
      polyethylene terephthalate (PET), etc., are the most abundant municipal solid 
      wastes (MSW). They have been utilized as a cheap carbon feedstock in the 
      synthesis of carbon nanotubes (CNTs) because of their high hydrocarbon content, 
      mainly carbon and hydrogen, especially for the polyolefins. In this review, the 
      detailed progress made so far in the use of plastics (both waste and virgin) as 
      cheap carbon feedstock in the synthesis of CNTs (only) over the years is studied. 
      The primary aim of this work is to provide an expansive landscape made so far, 
      especially in the areas of catalysts, catalyst supports, and the methods employed 
      in their preparations and other operational growth conditions, as well as already 
      explored applications of plastic-derived CNTs. This is to enable researchers to 
      easily access, understand, and summarise previous works done in this area, 
      forging ahead towards improving the yield and quality of plastic-derived CNTs, 
      which could extend their market and use in other purity-sensitive applications.
