Abstract
Handling of municipal solid waste (MSW) is described. A method for handling MSW in a single waste processing facility includes receiving the MSW at the waste processing facility. The MSW is separated into biomass, recyclables, and plastics. The biomass is processed at the waste processing facility to produce syngas using a gasifier. The plastics are also processed at the waste processing facility to produce naphtha, diesel fuel, and/or lubricants. Waste heat from the processing of the biomass and from the processing of the plastics is captured and used in the generating of electricity at the waste processing facility. Facilities for handling MSW are also described.
Claims53
A method for displacing services required by local landfills with a Virtual Landfill Terminal (VLT), the method comprising:
- receiving municipal solid waste (MSW) at the VLT;
- receiving waste tires at the VLT;
- separating the MSW into biomass, recyclables, and waste plastics at the VLT;
- processing the biomass, at the VLT, to produce syngas using an updraft gasifier;
- processing the waste plastics, at the VLT, to produce naphtha, low sulfur diesel fuel, and lubricants;
- processing of tires, at the VLT, to produce naphtha, low sulfur diesel fuel, and lubricants;
- capturing all produced liquid fuel in separate local tankage for storage at the VLT;
- providing custody transfer metering and truck loading for product sales and distribution from the VLT;
- capturing waste heat from the processing of the biomass, plastics and tires;
- and
- generating electricity, at the VLT, using the created syngas and waste heat;
- wherein using the VLT process eliminates methane emissions from all MSW processed;
- and
- wherein the method substantially removes all Landfill Gas emissions from the VLT, thus significantly lowering greenhouse gas emissions from the local landfill.
A virtual landfill terminal system for processing municipal solid waste, the system comprising:
- a municipal solid waste (MSW) receiving system, at the VLT, for receiving MSW and separating the MSW into biomass, recyclables, and plastics;
- a biomass processing system for processing the biomass to produce syngas, the biomass processing section having an updraft gasifier;
- a plastics processing system for processing the plastics to produce naphtha, diesel fuel, and lubricants using a rotary pyrolysis system;
- a tires processing system for processing the tires to produce naphtha, diesel fuel, and lubricants using the rotary pyrolysis system;
- a waste heat capturing system for capturing waste heat from the processing of the biomass processing section and from the plastics processing section of the plastics;
- and
- an electricity generator system for generating electricity using the syngas and waste heat.
