A sterilization and deodorization waste container includes an isolation chamber provided on an inner side of a container lid and a dual-wave band ultraviolet lamp tube installed in the isolation chamber. The dual-wave band ultraviolet lamp tube is capable of simultaneously generating a direct ultraviolet light wave and an ozone ultraviolet light wave. The isolation chamber includes a reflector housing having a light transmitting window facing an inner cavity of a container body. The dual-wave band ultraviolet lamp tube is controlled by a control circuit to turn on to generate the ultraviolets into an inner cavity of the container body while the container lid is closed and to turn off to stop generating the ultraviolet while the container lid is opened.

A method for separating a fraction of super-absorbent polymers (SAP) from post-consumer absorbent sanitary products, said post-consumer absorbent sanitary products further including at least one cellulose fraction and one plastic fraction. The method includes the steps of sterilizing the post-consumer absorbent sanitary products and treating said post-consumer absorbent sanitary products by immersion in a bath with an aqueous solution containing at least one oxidizing compound. The oxidizing compound is preferably selected from the group consisting of sodium persulfate, potassium persulfate, ammonium persulfate, potassium monopersulfate, and hydrogen peroxide; preferably hydrogen peroxide. The treatment by immersion allows cross-link cleavage and solubilizing of the SAP contained in said post-consumer absorbent sanitary products, and obtaining a suspension comprising i) a solid fraction and ii) a liquid fraction, wherein the liquid fraction comprises linear polyacrylate derived from the cross-link cleavage and solubilization of SAP.

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.
