A device for converting harmful waste products into environmentally friendly discharge is provided. The discharge, as a result of the waste destruction process, meets or exceeds the Environmental Protection Agency (EPA) standards. The device includes a waste disposal chamber where a crucible is positioned. The crucible is configured to retain a removable basket that is heated via induction heating. The waste residing within the removable basket is then vaporized and ionized within a vacuum to form a waste gas that is drawn through an accelerated jet of thermal plasma via vacuum suction. Once the waste gas passes through the plasma, it passes through a discharge duct where it is condensed by a heat exchanger and exhausted into the environment surrounding the device.

A quick blade repair and replacement enabled apparatus integrating medical waste shredding and sterilization is a dismountable integrally assembled vertical structure. Three chambers, including a loading and stirring, a shredding and a sterilization and discharging chamber are connected into a whole. Two repair gates are respectively on the left and right sides of the shredding chamber, they are designed as a whole together with the rotary blade shaft, when repair and replace the blades, only the repair gates need to be dismounted, and the replacement process can be finished outside the shredding chamber. The stationary blades are pressed on the inner wall of the shredding chamber by using binder plate, and bolts for securing the binder plate are screwed from outside.

Pulp fiber containing little ash is effectively recovered from a used sanitary product containing the pulp fiber and a polymer absorbent. The method according to the present invention comprises: a step for treating the used sanitary product with an ozone-containing gas and thus decomposing and removing at least a portion of the polymer absorbent in the used sanitary product; and a step for stirring the used sanitary product, that has been treated with the ozone-containing gas, in water or an aqueous solution containing an antiseptic and thus decomposing the used sanitary product into constituents. If required, the method may further comprise a step for separating the pulp fiber from the decomposition product obtained by the decomposition step.

A system for sanitizing and deodorizing garbage chutes using methane sensors in the trash chute that includes an ozone generating unit at the bottom of the trash chute. The system can include an ozone sensor as a safety device to ensure that ozone levels do not surpass a predetermined amount. The present invention works with a controller that controls the ozone generator based on a schedule program for a predetermined time of day. The present invention in an embodiment can include a plurality of additional sensors such as airflow detectors, occupancy detectors and the like.

A concentrated bioenzymatic cleaning product is provided which maintains a homogenous composition under static conditions and does not require shaking or mixing prior to dilution. The concentrated bioenzymatic cleaning product includes bacillus spores, a suspending and/or rheology modifying agent, an odor control agent, a pH adjuster, and water. The types and amounts of ingredients are selected to maintain the bacillus spores in suspension under static conditions, enabling the concentrated bioenzymatic cleaning product to be diluted using a proportioner system.

In newly industrialized countries and Third World countries, biogenic waste frequently constitutes a threat to ground water due to its being contaminated with bacteria and germs. In order to decontaminate such biogenic waste, one or more closable sanitizing chambers are fitted with open containers that are filled with the biogenic waste. The sanitizing chambers are closed, and hot waste gases (80° C. to 140° C.) are guided through the sanitizing chambers until germs and bacteria in the biogenic waste are killed. The sanitizing of biogenic waste eliminates the waste as a source of diseases and ground water contamination. The invention is suitable for decentralized locations, for example, in Third World countries or newly industrialized countries or places with stand-alone grids. The invention can have either a stationary or a mobile design.

A system including biogas purification and provides biogas as feedstock to a solid oxide fuel cell. The biogas purification treatment process provides a polished biogas that is substantially free of carbonyl sulfides and hydrogen sulfide. The system uses a biogas treatment apparatus, that includes apparatus such as a packed columns, comprising copper oxide or potassium permanganate packing material, and an activated carbon component configured to treat the biogas by polishing it to remove carbonyl sulfides and deleterious trace residues, such as hydrogen sulfide, that were not removed by any prior bulk H2S removal steps. In addition, an oil removal device is used to remove any entrained fine oil droplets in the biogas. A polished biogas having in the range of 60% methane is charged to the fuel cell. Electricity generated may be fed into a grid or used directly as energy to charge electrical-powered vehicles, for example. Energy credits are tracked in real time and are appropriately assigned.
