PP resin and PE resin is petroleum base from fossil we have to use in making our FIBC products, I am thinking of end of use, returned to landfill, by mixing particular master batch into our product in which, upon landfill, it will be perform similar to Biodegradable resin making better soil for trees. CO2 , H20 or Methane fully released because the trees will use CO2 n H2O as its Food. Methane is for energy recovery. From the best of my knowledges some particular fermented microbial or enzyme may doing this workable, but is there any one mix to our product to fulfill the purpose, or dilute them upon landfill. At least min 90% proportion decompose, but totally will be perfect.
