    Abstract: A pre-sorter forwards items from solid waste to designated processing paths in response to their size. Large items are manually processed to remove non-recyclables, to fuel a generator, to be returned to the pre-sorter after removal from a container, or forwarded to processing streams. The smallest items are forwarded to a first chain of machines that remove metal and glass from the items. Intermediate sized items are forwarded to an assembly that separates small, relatively dense, items from larger lightweight items. The former items are mixed and processed by a first chain of machines. The latter items are forwarded to a second chain of machines that separate and remove paper and other containers from recyclable metal and plastic. Multiple paper types are identified and removed by a third chain of machines. A remediator receives residual items from each of the first, second and third chains of machines.

    Abstract: The present invention provides a method of purifying polluted soil and/or burned ash containing heavy metals and/or organic compounds with a higher throughput than a conventional method. In this method, polluted soil and/or burned ash is dried by, for example, a rotary dryer so that the moisture content is 5% by mass or less, preferably 3% by mass or less, and then large lumps having a particle diameter of 10 mm or more are removed by a vibrating screen. Only an undersize portion is formed into a briquette having a volume of about 6 cm3 by a press molding machine. The briquette is charged in a rotary hearth furnace together with the large lumps, and heated in the furnace to remove or detoxify the heavy metals and organic compounds by evaporation with high efficiency.

    Abstract: A system for disposing of municipal solid waste 10) provides commercially-available equipment that is modified to initially remove identifiable unwanted components from the waste (12), and then chop the waste into small pieces (16) of a size suitable for handling and combustion. The moisture content of the waste is reduced in a closed system (20) by passing dry air through the waste in a confined space (30) to absorb moisture and produce moist air, which is then dehumidified via refrigeration equipment (34). The dehumidified air is recycled (30, 40) through the waste repeatedly through the closed system (20) until the water content has reached the predetermined amount. The waste is stored in a bunker (41) for later burning, or is immediately burned in a furnace (24) to produce heat that is used to produce steam (50), which drives a generator (26) to produce electricity (52) that is partly used to power the process and partly sold commercially.

    Abstract: A refuse recycling system which recycles municipal waste as energy, includes a shredder for shredding the waste and removing rejects via a feed pipe to a circulating fluidized bed reactor, the reactor producing flue gases. The reactor includes a side dense fluidized bed situated on the wall of the reactor which is provided with the feed pipe, the side dense fluidized bed extracting non-fluidizable heavy elements and transporting them to a coarse-particle sorter apparatus via an extraction duct disposed at a base of the side dense fluidized bed. At least a portion of the rejects from the shredder is fed into the coarse-particle sorter apparatus. The coarse-particle sorter apparatus cools the elements and extracts non-fluidizable inert matter from the elements, the remaining matter being fed back into the reactor. A module for recovering energy and for treating the flue gases output by said reactor is connected downstream from the reactor.

    Abstract: A soil remediation unit includes a counterflow drum for burning off volatile hydrocarbons and delivery to a cooler drum. Particulate-laden gases of combustion flow through a separator wherein the particle stream is delivered to the cooler drum and the gas stream delivered to a heat exchanger. The gas stream flows to a thermal oxidizer, the exhaust gas from which lies in heat exchange relation with the gas from the separator. Portions of the exhaust gas are passed into the separator in counterflow relation to the particles for remediating the particles.
