The PALINGENESIS PROCESS is a low temperature waste conversion technology, which operates through various stages of physical transformation coupled with a number of chemical, biochemical and electro-chemical reactions and mechanisms. The process is designed to neutralize, break apart, rearrange/restructure and convert the incoming waste materials, regardless of their basic form and chemical composition.The «Process» is an integrated technology employing a well established and proven cement solidification and stabilization process which is further enhanced and optimized by the use of proprietary chemical additives to pre-treat the waste materials and immobilize contaminants, rendering the waste material inert and non toxic, while at the same time neutralizing all heavy metals.
Utilizing custom made machines and specialized equipment, the process treats a variety of waste streams such as municipal solid wastes, industrial and commercial hazardous and toxic and non hazardous and non toxic wastes including metal bearing waste, water sludge, chemical, paints and solvents, oil based sludge’s, hospital, spent acids and almost all types of hazardous and toxic waste sludge’s.
The goal of the Palingenesis Process is to limit and totally prevent the spread of the pollutants, via leaching of contaminated material in to the environment. This is achieved by a method of solidifying and encapsulating the waste after the treatment process in a concrete matrix such as a block or other end product with high structural integrity. The most common form of solidification and stabilization (S/S) is a cement-based process that physically encapsulates the contaminant. It traps or immobilizes contaminants within their «host» medium. This method has been used to treat a wide variety of toxins including heavy metals and organic pollutants, like creosote and petroleum products. The ability of solidification and stabilization technology to treat such a wide range of hazardous constituents is one reason why it has been so widely used. With the addition of the Palingenesis proprietary additives this age old, proven method is greatly enhanced to meet the challenges of the 21st century and beyond.
The performance of the Palingenesis process was evaluated over a period of ten months, by the Industrial Technology Development Institute, a division of the Department of Science & Technology of the Philippine Government, using the accepted protocol of the US EPA and the European Union, being TCLP (Toxicity Characteristic Leaching Procedure) and SPLP (Synthetic Precipitation Leaching Procedure).
The Conclusion of ITDI-DOST Evaluation Report says:
«As a method for treatment of hazardous and toxic wastes to render them inert and non toxic and acceptable for the landfill system, the Palingenesis Process, has definite technical merit as it improves the physical characteristics of the wastes by over 99% (Ninety nine percent); reduces transfer of pollutants by decreased surface area; and reduces pollutants solubility. Additionally the percentage of retained metal concentration after the application of the Palingenesis Process resulted in high efficiency in excess of 99.9%».
«The end-product of the process, being concrete building materials from a variety of waste streams passed 100% of the US EPA TCLP Regulatory Levels for toxic and hazardous heavy metals and the building materials fabricated from the treated waste surpassed the US EPA 1989 satisfactory Unconfined Compressive Strength; the end product also passed European Standard Regulatory Requirements».
«The technology is appropriate in the production of construction materials using municipal solid and selected industrial and commercial wastes because of its high UCS value».
The PALINGENESIS PROCESS is simple. Unsorted wastes are introduced into the feed hopper before passing through the shredder for particle size reduction. During the shredding and grinding process, an increase in temperature occurs which initiates the destruction of pathogens, bacteria and toxins.
An ozone machine along with proprietary additives eliminates noxious smells and the wet and dry scrubbers remove dust particles. The vibrating sizing screens separate up to 98% of the biodegradable from the non-biodegradable waste. The treated wastes are mixed together with proprietary liquid additives that create an exothermic reaction resulting in higher temperatures and internal pressure which begin the process of molecular change and complete the destruction of pathogens, bacteria and toxins. Finally, various solid additives act as binding agents when added to the waste inside the ribbon blenders or mixing tanks. This processed mixture is then carried to injection or molding machines for the production of economically viable, environmentally sound and high quality consumer products. The separated organic materials are processed into compost or converted into energy pellets for consumer or industrial use, or developed into a wide range of horticultural products and accessories.
Palingenesis Manufacturing Inc. engaged the Industrial Technology Development Institute as a qualified third-party governmental institution to conduct a scientifically objective and impartial evaluation of the actual performance of the technology.
In addition to hazardous and toxic waste streams, studies were conducted on mixed solid wastes. The fractional composition of this sample feed waste was determined first by component segregation and then by the weighing of each component using standard weighing practices. The initial results of the study as shown in the Table and chart below illustrates that the waste sample was characteristically household, industrial, and commercial in nature.
Various studies and tests were conducted on this type of waste feed in order to further optimize the formulation of the additives as well as the operating conditions, including the compressive strength and leach ability characteristics of the finished products. Moreover, the associated environmental impacts of processing these wastes have been monitored and fully documented.
The data provided by the ITDI and the DOST shows that the wastes constitute approximately 60% of the total volume of the wet hollow block mixture. Experimental runs were conducted by the researchers of the Environmental Division of the Industrial Technology Development Institute. Preliminary results show staged formulations were derived from producing concrete replacement hollow blocks.
