A waste management system comprises a waste bin storing waste, wherein the waste bin comprises a smart waste bin sensor device installed on the waste bin of a waste bin owner. The smart waste bin sensor device comprises a set of sensors that sends and receives signals through a wireless network to a cloud server. The set of sensors implements, operates, detects, measures, and monitors environmental conditions inside or outside the waste bin. A waste and litter sensor detects, measures, and monitors a waste type, a waste volume, a litter type, a litter level, a biohazardous waste type, and a biohazardous waste level. A pathogen biosensor detects, measures, and monitors a pathogen type and a biosafety level. The pathogen biosensor comprises a sterilizer to kill pathogens. A waste bin mobile application and a waste collection facility application functionality enable a user to monitor waste in the waste bin.

An irrecoverable-waste feeding and metering apparatus for feeding a waste separator, comprising:—a loading hopper having a mixing compartment and a discharge duct which extends between the mixing compartment and a discharge mouth thereof, for discharging material from the latter;—a central auger and two lateral augers; the central auger extending into the discharge duct and into the mixing compartment and the lateral augers are arranged inside the mixing compartment each on one side of the central auger;—a transfer device having a feed channel which has a loading portion and a feeding portion. The transfer device comprises two transfer augers extending from the loading portion along the feed channel and which each have a first helicoid. The first helicoid of a first transfer auger has a direction opposite to that of the first helicoid of the second transfer auger.

A solar panel cutting unit may include a frame, a transport roller unit provided at the frame to transport, in a first direction, a solar panel having a glass plate, an adhesive layer, a solar cell layer, and a backsheet layer stacked sequentially, a heating unit to heat the solar panel, a pair of pressurization roller units to pressurize and transport the solar panel, a trimmer unit that moves in a second direction perpendicular to the first direction and removes the backsheet layer, the solar cell layer, and the adhesive layer, a peeling unit that inserts a blade into the adhesive layer of the solar panel passing by the trimmer unit and removes a flexible film to which the solar cell layer and the backsheet layer is adhered, and a collection roller that collects the flexible film peeled by the peeling unit.

A reagent set includes an oxidant, acid, and adsorbent, which is used in a method for reducing the leachability and release of PFAS, mercury, and other contaminants from soils, sediments, and other solid materials or waste when treated materials are exposed to acid rain, snow melt, runoff, landfill leachate, etc. The reagents are mixed with a quantity of contaminated material and water is added as needed in order to reduce the leachability of the contaminants from the treated host material, where the admixture end-product suitably removes contaminants from fluids that contact and/or otherwise permeate and/or pass through and/or around the treated admixture. The reagent set and method of use offer environmental professionals long-term, economically viable waste management solutions for removing contaminants from contamination source areas, spill and manufacturing release sites, impacted media, and landfills, as well as from the fluids that contact reagent-treated material.

A solar panel disassembling apparatus according to an embodiment of the present disclosure separates a glass plate of a solar panel and a film layer bonded to the glass plate from each other. The solar panel disassembling apparatus includes a supply module that stands and fixes the solar panel such that a bond line between the glass plate and the film layer is exposed upward and downward and that moves the solar panel in a parallel direction parallel to a bonding surface between the glass plate and the film layer, and a wire-shaped cutting blade that is disposed in front of the solar panel in a movement direction of the solar panel to have a distance from the supply module, is disposed in parallel to the bonding surface, and separates the glass plate and the film layer from each other.

An anaerobic digestion system may include a material grinding/pulping portion, a hydrolysis portion arranged downstream of the grinding portion, a multiple chamber anaerobic reactor arranged downstream from the hydrolysis portion and including a gas collection and reintroduction system, a collection system for collecting digestate and gas from the anaerobic reactor.
