The composite mixture is configured to combine with the bodily remains to decompose the bodily remains. The combined mixture has a reduced pH for reducing the detrimental effects of the bodily remains on the environment.

A process for preparing whitened fly ash includes the steps of: (a) subjecting fly ash to a size classification step to obtain size classified fly ash having a particle size such that at least 90 wt % has a particle size of from 44 ?m to 250 ?m; (b) optionally, contacting the size classified fly ash from step (a) with water to form a slurry, wherein the slurry has a solid content of less than 40 wt %; (c) subjecting the slurry obtained in step (b) to an exhaustive magnetic separation step to form magnetically treated fly ash, wherein the exhaustive magnetic separation step includes a first magnetic extraction step and a second magnetic extraction step, wherein the second magnetic extraction step is carried out at a higher magnetic field strength than the first magnetic extraction step; and (d) subjecting the magnetically treated fly ash obtained in step (c) to milling to form whitened fly ash.

A method of recovering fly ash, including a firing step in which raw fly ash powder containing unburned carbon is fired to remove the unburned carbon by burning; measuring the content of unburned carbon in the raw fly ash powder; and obtaining a fine fly ash powder which is a component under a sieve and has a decreased content of unburned carbon as a result of sieve-classifying the raw fly ash powder. The perforation size of the sieve used in the sieve-classifying step is set depending upon the content of unburned carbon in the raw fly ash powder. The sieve has a small perforation size when the content of unburned carbon is large, and the sieve has a large perforation size when the content of unburned carbon is small. The fine fly ash powder, which is the component under the sieve, is recovered through the firing step.

An ash management trench system is provided for harvesting byproducts from sluice water, such as a discharge from a power plant. The system comprises a first section comprising at least one flow control structure. The at least one flow structure is typically configured to capture a predetermined byproduct. The system further comprises a second section comprising a stilling basin. The second section is coupled to the first section by a connection structure.

A method for separating composite materials and mixtures, in particular solid-material mixtures and slags, and to a device for carrying out said method. The method for separating composite materials and mixtures comprises the step of transporting the composite material or the mixture through a separating device. The composite material to be separated or the mixture to be separated is excited by mechanical impulses as it passes through the separating device and is thereby separated. The device (1) for carrying out the method comprises a drive unit (21) for driving a rotor element (32), which is connected to a bearing/shaft unit (22) and which is part of a rotor unit (31). The rotor element itself has at least one rotor tool (33) and each rotor tool has at least one rotor tool component (34) and is surrounded by a stator element (42), which is part of a stator unit (41). The stator element itself has at least one stator tool (43) and each stator tool has at least one stator tool component (44). The rotor element and the stator element are substantially cylindrical.

Provided are: a novel heavy metal treatment agent having improved performance for treating elements of groups 6-16 of the periodic table or compounds thereof, including treatment of incinerated ash and wastewater, etc.; and a method for treating incinerated ash and wastewater using the heavy metal treatment agent. This heavy metal treatment agent includes at least one dithiocarbamate of one or more amine compounds represented by any of formulae (I) to (III):

##STR00001## wherein m represents an integer of 3 to 6;

##STR00002## wherein each of the n Xs independently represents a hydrogen atom or a 2-aminoethyl group, at least one X is a 2-aminoethyl group, n is an integer of 1 to 3 and the total number of nitrogen atoms is 4 to 8; and

##STR00003## wherein o is an integer of 0 to 2, p is 0 or 1, q is 0 or 1, r is an integer of 0 to 3, the sum of o, p and r is greater than or equal to 1, and the total number of nitrogen atoms is 3 to 7.

A method for efficient disposal of dioxin and heavy metals based on calcium-based heat storage of MSWI fly ash is provided. According to the method, MSWI fly ash washed with water is treated with ammonia, and carbon dioxide is continuously introduced under stirring. The ammonia provides OH.sup.? for a carbonation reaction of the MSWI fly ash and promotes removal of sulfate ions. After centrifugation of a reaction solution, calcium carbonate obtained as a solid part is transported to a calcinator of a solar chemical heat reservoir and calcined into calcium oxide by means of solar energy obtained by a solar concentrator. CO.sub.2 produced in a calcination process is collected, cooled and liquefied, followed by a carbonation reaction with the calcium oxide in a carbonation radiator. After the operations above are repeated in cycles for several times, carbonated MSWI fly ash is obtained for use as an aggregate or a filler.

An impoundment closure system that employs a low permeability membrane on top of a waste materials with ponded water on top of the low permeability membrane.

There is provided A process for producing a biocompatible soil mixture from cremated ash remains, the process comprising: mixing cremated ash remains with a soil base material and a nutrient composition to produce a pre-conditioned mixture, the nutrient composition comprising at least one of paramagnetic material, soil conditioner and fertilizer; and conditioning the pre-conditioned mixture using a microbial conditioner to adjust the adverse chemical properties of the cremated ash remains biologically to produce a conditioned soil mixture being biocompatible for a legacy tree, wherein the pre-conditioned mixture comprises less than 10% of the cremated ash remains by volume.
