Abstract
A system and method are provided for converting solid waste into new plastic products by utilizing the plastic from a landfill in new products and the fuel resources in the landfill in the manufacturing process. Biomass waste is combusted by a combustion system to generate residual heat and heated exhaust, and the residual heat and heated exhaust is used to fuel the manufacturing of new plastic products from the recovered plastic waste. Methane gas recovered from the landfill can also be used as a fuel source for heating manufacturing machinery and generating electricity used in the manufacturing processes.
Claims21
A method comprising:
- providing recovered plastic waste from a waste repository;
- combusting biomass waste by a combustion system to generate residual heat and heated exhaust;
- and
- using the residual heat and heated exhaust in manufacturing new plastic products from the recovered plastic waste.
A system comprising:
- a waste repository comprising plastic waste and biomass waste and a sorting station configured for sorting recovered plastic waste and recovered biomass waste from other waste in the waste repository;
- a combustion system configured to combust separated biomass waste to generate residual heat and heated exhaust;
- and
- a plastic product manufacturing system configured to use the residual heat and heated exhaust in manufacturing new plastic products from recovered plastic waste from the waste repository.
