Foremost Recycling & Waste Management Company THE GREEN BOX facility.
Environmental degradation due to the various forms of waste is at an all-time high. From liquid waste, organic waste, hazardous waste, recyclable rubbish, and solid waste, these forms of waste contribute a great deal in damaging our environment. However, some waste can be recycled while the rest can be managed and disposed of in an environmentally friendly manner. Here at GRET,INC, we specialize, In The management and treatments of MSWs by thermal plasma arc gasification technology increasingly viewed as the best suitable and economically viable approach for the management of wastes. THE GREEN BOX Facility.
The key product from these thermal gasification technologies is the conversion of MSW into synthesis gas (syngas), which is predominantly carbon monoxide (CO) and hydrogen (H2), which can be converted into energy (steam and/or electricity), other gases, fuels, and/or chemicals.
One approach or option for the use of the key product from the conversion of MSW into syngas by a thermal process is for generation of steam and/or electricity in a powerhouse.
WHAT IS PLASMA ARC GASIFICATION?
Plasma arc gasification is a high-temperature pyrolysis process whereby the organics of waste solids (carbon-based materials) are converted into syngas and inorganic materials and minerals of the waste solids produce a rocklike glassy by-product called vitrified slag. The high temperature during the process is created by an electric arc in a torch whereby a gas is converted into a plasma. The process containing a reactor with a plasma torch processing organics of waste solids (carbon-based materials) is called plasma arc gasification. The plasma arc gasification reactor is typically operated between 7,200 and 12,600F.
The inorganic minerals of the waste solids (MSW) produce a rocklike by-product. Since operating conditions are very high (7,200–12,600F), these minerals are converted into a vitrified slag typically comprising metals and silica glass. This vitrified slag is basically none leaching and exceeds EPA standards. Metals can be recovered from the slag and the slag can be used to produce other by- products such as rock wool, floor tiles, roof tiles, insulation, and landscaping blocks, to mention a few. The vitrified slag, being environmentally acceptable as a recyclable by-product, is one of the more positive attributes of plasma arc gasification process for the management of MSW.
Our population is still growing and we are producing more garbage, even with the recycling efforts in full operation. We have come to the “place in time” where the momentum of TECHNOLOGY can help “protect human health and welfare,” and thus the environment, by creating an infrastructure design, creation and building of sustainable MSW processes that can turn our WASTE PROBLEM into useful GREEN ENERGY for the betterment of ALL.

Plasma Gasification Technology
Plasma gasification technology is particularly suitable for disposal of hazardous and radioactive wastes. Seen as an attractive option for disposal of municipal solid wastes as well. This technology has an edge over the other processes involving combustion as it can it can turn solid municipal waste (organic as well as inorganic) into a clean, green, renewable fuel in the form of a synthesis gas (SynGas) with almost no residues that require further disposal.
The major advantages of plasma arc technology are:
1. Compared to combustion/incineration technology, it creates much less atmospheric pollution.
2. In techno-economic terms, oxides of nitrogen and sulphur are not emitted during normal operations because the system works in the absence of oxygen.
3. Toxic materials become encapsulated and are therefore much safer to handle than the toxic ash left by combustion/gasifier processes.
Managing domestic, industrial and commercial waste has traditionally consisted of collection, followed by disposal. Depending upon the type of waste and the area, a level of processing may follow collection. This processing may be to reduce the hazard of the waste, recover material for recycling, produce energy from the waste or reduce it in volume for more efficient disposal.
