Embodiments of the present invention may provide managing waste including providing non-sorted solid waste (1), processing non-sorted solid waste in a waste handling system (21), shredding (26) non-sorted solid waste to create shredded non-sorted solid waste (27) in a waste handling system; introducing shredded non-sorted solid waste into a thermochemical conversion reactor (4); heating and even chemically converting a shredded non-sorted solid waste; producing hydrochar (22) and a recyclable materials fraction (23); recycling water (24) used in the heating and chemically processing of the shredded non-sorted solid waste in a thermochemical conversion reactor in said waste handling system; sorting (25) the recyclable materials fraction; fueling (28) a thermochemical conversion reactor with hydrochar (22); and perhaps even recycling heat from a thermochemical conversion reactor in the waste handling system.

The present invention relates to a novel chemical composition for removing oil from asphalt shingles. The composition preferably comprises approximately 48% water, 48% fuel such as gasoline or diesel, 2% alcohol, 1.5% citrus and 0.5% enzyme by weight. The composition is used in a system comprising a plurality of tanks that operate under a controlled heat and pressure to breakdown oil components within the shingles. The system uses a closed loop process to feed back the residual ingredients of the composition for reuse. Once through the system, the oil is removed from the asphalt shingles, thereby preventing oil from leeching into the groundwater when the asphalt shingles are disposed of.

In the disclosed solution sand to be cleaned is thermally cleaned by rotating the sand being cleaned in a large oven (1) by rotating the oven (1). Before cleaning, the sand may be pre-processed by crushing any lumps and cleaning the sand fraction by magnetic separation. Preprocessed sand to be cleaned and heat energy are fed (5) into the rotating oven. The oven (1) is set slightly inclined so that a second end of the oven (1) is lower than a first end. The inclination and rotating speed of the oven (1) as well as the feed amount of sand are adjusted, whereby the advancing speed of the sand may be adjusted, as well as the ratio of the sand being cleaned to the volume of the oven (1) kept as desired. The temperature of the oven (1) is monitored at the coldest area of the oven, which is substantially at the second end of the oven. The temperature of the oven (1) is adjusted by adjusting the amount of heat energy fed in. By means of temperature monitoring and knowing the advancing speed of the sand, it is also possible to determine the average temperature of the sand and adjust it as desired by adjusting the supplied heat energy. Finally, the cleaned sand is let run (12) from the second end of the oven (1).

Provided is a treatment method whereby it becomes possible to recovery copper, nickel and cobalt, which are valuable metals, contained in a lithium ion battery waste and to separate copper, nickel and cobalt from one another effectively. A method for treating a lithium ion battery waste according to the present invention includes: an alloy production step S1 of introducing the lithium ion battery waste into a furnace and then melting the lithium ion battery waste by heating, thereby producing an alloy containing copper, nickel and cobalt; and an electrolytic purification step S2 of subjecting the alloy to such an electrolytic treatment that the alloy is charged as an anode into a sulfuric acid solution and then electricity is conducted between the anode and a cathode to electrodeposit copper contained in the alloy onto the cathode, thereby separating nickel and cobalt from each other.

Porous amorphous silica can be obtained from siliceous plant matter containing non-siliceous inorganic substances. The siliceous plant matter is soaked in an aqueous solution which includes a chelating agent. The chelating agent is present in an amount which helps to extract at least some of the non-siliceous inorganic matter. The aqueous solution is then separated from the siliceous plant matter. Beneficial properties are imparted to the siliceous plant matter by controlling the amount of at least one preselected non-siliceous inorganic substance in the siliceous plant matter. At the end of the process, the siliceous plant matter is heat treated in the presence of oxygen at a temperature to produce the resulting amorphous silica having the beneficial properties.
