Process for treating solid waste containing an organic fraction, comprising an initial step of extrusion pressing the waste with production of a solid fraction and a liquor. The solid fraction is subjected to a milling treatment at a pressure lower than the atmospheric pressure in a rotary mill that produces a sanitized dry solid and water. The liquor is subjected to a treatment of anaerobic digestion in three subsequent steps, with production of biogas and of a digestate that is subjected to evaporation under vacuum to obtain a concentrated compost and steam, re-used in other steps of the process. The sanitized dry solid and the biogas can be used as fuel to produce thermal and electric energy to be used in the process, which also allows surplus energy to be obtained.

The present invention recognizes that medical devices, such as but not limited to contact lenses, can be made having a coating made at least in part using printing technologies to provide drug storage and drug release structures. The coating preferably includes at least one drug reservoir layer and a least one barrier layer, and can include structures, such as but not limited to capillary structures that alone or in combination modulate the release of the drug from the coating. One aspect of the present invention is a medical device that incorporates a drug in at least one coating. A second aspect of the present invention is a method of making a medical device that incorporates a drug in at least one coating. A third aspect of the present invention is a method of using a medical device of the present invention to treat, prevent from having, prevent from developing, control, reduce the severity, or reduce the progression of a disease, disorder or condition of a subject.

A method is provided which, by a simple process, separates and recovers pulp fibers from a used absorbent article that contains pulp fibers and a superabsorbent polymer. A used absorbent article is treated with an aqueous solution that contains greater than or equal to 0.05 mass % of at least one kind of terpene selected from the group comprising terpene hydrocarbons, terpene aldehydes, and terpene ketones and that contains a deactivating agent that can deactivate the superabsorbent polymer; the superabsorbent polymer is deactivated, the adhesive that bonds together the constituent materials of the absorbent article is dissolved with the terpene to decompose the absorbent article, the pulp fibers are discharged to outside of the absorbent article, and the pulp fibers are separated from the absorbent article and recovered.

The present invention is generally related to a lens care system and method for disinfecting and cleaning contact lenses. A lens care system or method of the invention is based on electrolysis of an aqueous chloride solution for generating germicide species (e.g., chlorine, hypochlorous acid, hypochlorite, or combinations thereof) and subsequent in-situ electrolysis of hypochlorous acid or hypochlorite in the aqueous solution for neutralizing the generated germicide species.
