Provided is a coating composition that include a first resin having a Tg above about 25 C. and a second resin having a Tg above about 50 C. The coating composition and/or resins thereof are at least partially hydrolysable in a hot caustic solution. Further provided are a method for applying the coating composition to a label substrate, a label substrate coated with the coating composition, and a recycling method. Sleeve labels for articles such as containers may be formed from label substrates by forming a bonded seam with the coating composition. The coating composition maintains the bond in the seam during sleeve label shrinking and during article life. Label removal during recycling is relatively easy, as the coating composition in the seam de-bonds in a hot caustic solution.

According to an embodiment, a label peeling device includes a container holding portion configured to hold a specimen container, and a cutter holder configured to detachably hold a cutter, to apply a blade of the cutter to a side surface of the specimen container held by the container holding portion with a label being attached to the side surface, and to move along an axial direction of the specimen container, thereby peeling the label attached to the side surface of the specimen container.

A method for recycling materials having an affixed label is disclosed. The present invention also includes labels and adhesives that is readily removable from a material during a process for recycling the material.

A method for cleaning a storage tank to which sodium metal is adherent, the method containing: filling, with an inert oil, the storage tank to which sodium metal is adherent; subsequently adding water, water vapor, or a humidified inert gas to the inert oil; providing a gas discharge line to the storage tank and measuring the hydrogen gas concentration in the gas discharge line; regulating the amount of the water, water vapor, or humidified inert gas to be added per hour in accordance with the level of the hydrogen gas concentration; regulating the temperature of the inert oil to 0-98 C.; and converting the sodium metal into caustic soda while changing the liquid surface level of the inert oil in parallel with addition of the water, water vapor, or humidified inert gas to the inert oil.

The present invention relates to a bottle label removing and cleaning integrated system, including a support platform, and further including a label removing and cleaning machine, a bouncing separation screen, a cleaning liquid separator, and a cleaning liquid buffer tank that are sequentially connected, where the label removing and cleaning machine is mounted on the support platform, the bouncing separation screen is configured to separate cleaning water, labels, and impurities from main materials, and the cleaning liquid buffer tank is configured to accommodate cleaning liquid purified by the cleaning liquid separator.

A method for recycling materials having an affixed label is disclosed. The present invention also includes labels and adhesives that is readily removable from a material during a process for recycling the material.

The present invention relates to an adhesive compositions, facestocks and/or packaging labels containing same, where such compositions, facestocks and/or labels are designed to facilitate the recyclability of a plastic article formed from any suitable polymer or mixture of polymers (e.g., a polyethylene terephthalate (PET), high density polyethylene (HDPE), polyvinyl chloride (PVC), low density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), or others of all plastic types), or even glass bottles. In another embodiment, the present invention relates to a method for removing an adhesive composition, facestock and/or packaging label containing same, from a plastic article that is to be recycled.

The water heater clean out device of the present invention is attached to a vacuum cleaner to vacuum up the built-up solids deposit from a bottom of a water heater. The articulating joint of the present invention allows the user to be able to easily reach all areas of the bottom of the water heater. The water heater clean out device uses a pull cord and pulley/cord reel system to maneuver the end of the tool inside the water heater.

Process for cleaning oil tanks and vessels by treating the flotation generated residues and reusing the washing water for the purpose of cleaning oil-containing tanks and containers, combining the use of water spurts and application of neutral biodegradable chemicals, such as degreasing solvents or descaling detergents, installing a skimmer under the submerged hydraulic pump, separating solids using a double vibratory sieve and oily liquids through flotation, recovering and reincorporating the oil into the production process of the unit and reusing the washing water.

There is described a washing machine configured to wash empty containers adapted to be filled with a pourable product, the washing machine includes: a conveyor device configured to convey a plurality of containers along a washing path in an advancement direction; at least one tank for holding a cleaning medium, the washing path extending within and along the tank; and a hollow passage which extends through the tank and which is fluidly isolated from the tank. The washing machine further includes a pair of extraction devices arranged in fluid communication with the tank, fluidly isolated from the hollow passage, and configured for detaching/removing labels from the containers advanced in the tank and for receiving the detached/removed labels, thereby extracting such labels from the tank.
