HOW WE'RE DOING IT

Recycling/Sorting/Pelletization Process For MSW and Green Waste

The management of residential/commercial MSW or Biowaste at the proposed facility is an alternative for dealing with the waste disposal issues presently facing the regions of the world. The primary objective of our technologies is to reduce the volume and weight of the waste that is presently disposed of via a landfill operation of which there is no use, and to provide an environmentally acceptable renewable alternative fuel product that can be used for the benefit  of energy consumers currently dependant on coal, coke or gas.

Rather than the present approach of all waste materials being sent to landfills, the Global NRG technology consists of  processes whereby dry recyclable materials, with a monetary and usefulness value, are extracted from the incoming waste stream for sale in the recyclables marketplace. The residual combustible waste is fed in combination with other high BTU products such as polyfilm into a high-density high BTU, pelletizing system. Instead of MSW handling at current transfer stations, the residential garbage collection trucks or biowaste would be delivered directly to the pellet processing facility.

The designed equipment alignment enables the efficient processing of MSW and results in the recovery of at least an additional 8-10 percent of the black bag waste stream, which is recyclable material such as types 1 and 2 plastics, cardboard, aluminum, tin, and glass. Even with the best efforts applied to source separation recycling programs, some of this material is currently missed and ends up in landfill.


The process begins with the delivery of MSW to the plant by the garbage pick-up trucks used by the region delivering waste to the facility. The MSW or biowaste is dropped on to a tip floor, with the overhead grapple operator removing any obvious hazardous or large materials to the side for either later use or disposal. The remaining materials are then moved to the incoming material hoppers, where they are transferred on to transverse conveyors, which feed onto the incline conveyors for auto sorting or onto the initial manual sorting station, and on to bag busters. The materials are then passed through a large material trommel, where smaller items are deposited through the small material trommel and/or on to separators, screens and a plastic removal system to positively select those materials that are to either be used in the pellet or sold as recyclable product. The remaining minor amount of materials that must still be sent to landfill, are then stored until sufficient amounts are retained to be sent via truck to the selected landfill site.

During the process eddy current separation and magnets are used in several locations to select both ferrous and non-ferrous materials for delivery to the recycling markets.

The positively selected materials that are moved on for use in manufacturing the fuel pellet are then shredded, fiberized, and stored in a silo. This stored material is then mixed with high BTU materials such as carpet waste, poly film or other acceptable materials and then pelletized and stored for sale and transportation to their final destination for use as a renewable alternate fuel.

The NRG Pellets are used to create green energy.

Harnessing Agricultural Wastes for Energy

Each year the agricultural industry produces millions of tonnes of waste plant matter containing energy that is either burned or unused.

Agricultural waste comes in a wide and plentiful variety. Cassava stems and stalks, rice husks, forestry wastes, wheat straw, maize stalks, chicken litter, green bark, sawdust and chips, corn cobs and stubble, peanut hulls, cotton seed hulls, sugar cane trash, oil seed plant waste, grass cuttings to name but a few. All have an energy value.

Using modern technology the Global NRG processes these wastes so they can be harnessed to provide a clean renewable energy resource. These biowastes can be turned into NRG fuel pellets of varying calorific value to suit the end user's specifications, replacing fossil fuels in many instances or can be gasified.

Gasification of the pelletized waste in the Global NRG process produces a synthetic gas with properties similar to natural gas, called syngas. Syngas is an ideal way of storing biowaste energy.

Syngas can in turn be used to create steam via boilers or gas turbines to generate green electricity, or to fuel gas internal combustion engines to drive electricity generators or provide mechanical power for industrial and farming use. Syngas can be used for domestic heating purposes or converted into ethanol, methanol or biodiesel for use in transport, and has multiple applications in the chemical industry.

All of this is done in harmony with food production as the Global NRG process does not use the food component only the waste, or can use special oil producing crops such as Jatropha or Stinkweed (Pennycress) that are not used in the food chain for humans or animals. Other high yielding crops such as cassava can be especially grown for their energy value. Most countries that grow enough food to feed themselves generate sufficient waste to provide more than 68% of their energy needs in the form of renewable energy resources.
