AB  - Careless release of plastic waste is a pressing problem for marine and other 
      eco-environments, and materials recycling of this stream is an open problem. For 
      this purpose, a new metal-free acidic carbocatalyst with 8 wt % sulfur is 
      constructed from a side product of the paper industry namely Na-lignosulfonate. 
      The catalyst shows an extraordinary performance for the fragmentation of polymer 
      waste which smoothly occurs above the ceiling temperature of the polymers. The 
      reaction is run without hydrogen and at ambient pressure with commercially 
      available high-density polyethylene (HDPE) as well as a real polymer waste 
      mixture of high and low-density polyethylene (HDPE, LDPE). In all cases, a 
      homologous series of n-alkanes and n-alkenes are obtained. The unique sulfur-rich 
      carbonaceous structure (transfer hydrogenation functionality) and the metal-free 
      character of the acidic carbocatalyst makes it inert against many typical 
      catalyst poisons, among them water, salt, polar functionalities, and sulfur 
      species. The described performance in plastic recycling, as well as the low cost 
      and large-scale availability of lignosulfonate from the pulp industry, makes this 
      metal-free acidic carbocatalyst promising for real-life environmental 
      applications.
