Arc Southern Energy, LLC

	ARC Southern Energy provides gasification solutions to convert following types of waste into energy: Municipal Solid waste (MSW) Medical Waste Sewage Sludge Refinery Waste The solution that ARC Southern Energy offers is extremely flexible and – it is portable, modular and scalable. Arc Southern Products that it offers for the waste to energy are as follows: CE - 25 CE - 250 CE - 500
	Innovative Plasma Arc-Based Waste-to-Energy Conversion Wood chips, lignite, saw dust, coal fly ash all can be combined with other feeds such as sewage sludge to produce electric power in a proprietary plasma arc gasification process, provided that the mixture is adequately dried before gasification. Working with different partners such as adaptiveArc, Inc. and TensorCrete, ARC Southern Energy LLC has developed wet biomass feed dryers that use gasification process heat. Using process waste heat to remove moisture from feeds reduces the moisture penalty and allows the process to operate at greater overall thermal efficiency. When operated onsite at landfills or sewage processing plants, the plasma arc gasification process can also efficiently convert methane-rich landfill gas and digester gas to electricity. When the overall calorific value of the mixed feed is approximately 5000 btu/lb, or greater, the process can generate between 1.2 and 1.6 MW of net power for every 100 TPD of capacity. Co-processing of coal fly ash with wet biomass feeds can also generate a gasifier ash that has the proper elemental composition to be formulated into supplemental cement materials (SCM). This providing an additional source or revenue for the overall process. Other types of feedstock’s yields different types of products such as fertilizers and chemicals In a number of economic scenarios, running the system on a variety of feed stocks the overall process is profitable based on electricity and product sales. Additional avoided tipping and hauling fees, carbon credits and recycle credits that may be available can substantially increase overall profitability of the process.



	This modular portable plasma Arc gasifier system from adaptiveArc, Inc. rated at 250 tons per day, is anticipated as the central component of the ARC Southern waste-to-energy system. The following is an example of using the process developed by our partners TensorCrete / adaptiveArc which converts, high carbon fly ash to electrical energy and supplemental cement products.



	The proprietary process converts waste to energy with essentially zero discharge. - As shown, fly ash components are either converted to electricity or recycled as supplemental cement materials. - Pollutants created during the combustion of the syngas are returned to the gasifier and recycled to extinction.

	Re-processing of Coal Fly Ash to Supplemental Cement Materials Low carbon coal fly ash has been successfully used as a supplemental cement material (SCM) at proportions of up to 50% since the early 20th century. High carbon fly ash (>6% carbon) is not suitable for cement and is generally stored in impoundments. Increased use of activated carbon injection to remove SOx and NOx from flue gas renders more and more fly ash unusable for cement. This waste material generally ends up in impoundments where it can constitute an environmental hazard. Our partners, TensorCrete, and adaptiveArc, Inc. is developing a proprietary system based on an innovative, modular and mobile plasma arc gasifier, that can re-process high carbon fly ash to generate electricity and produce a value added SCM product. In one version of this process, the fly ash is size separated into high carbon and low carbon fractions. The low carbon fraction is sent to storage for later blending into the SCM formulation. The high carbon fraction is sent to the gasifier where the carbon is converted to syngas and then to electrical energy. The remaining inorganic ash from the gasifier can be as a much as 80% or so of the incoming ash volume. This clean, low carbon gasifier ash is blended with other materials in a proprietary post-gasification process to make a reactive cementitious material. The exact formulation for the resulting SCM varies by fly ash type, amount of separated low carbon ash available, as well as process and local market conditions. Optional equipment for drying and processing wet fly ash from slurry ponds, for mixing feed stocks, and for post processing to make reactive cement will be available in modules as required.



	Similar approaches are being developed for other products such as chemicals and fertilizers.
