An adsorbent for perfluoroalkyl and polyfluoroalkyl substances, wherein the adsorbent comprises one or more proteins. The one or more proteins may be selected from plant proteins, albumins, globulins, edestin, glycinin and/or beta-conglycinin. Use of an adsorbent for treatment of a material contaminated with perfluoroalkyl and polyfluoroalkyl substances. There is also provided a process for the treatment of ground water contaminated with perfluoroalkyl and polyfluoroalkyl substances, wherein the contaminated ground water is pumped to the surface and directed to an adsorption step comprising the adsorbent.

Vegetable fiber sponge (1) for domestic use is a cylindrical body (2) permanently attached at its ends (5) and has at least three internal holes (3) and is composed of compact and entangled vegetable fibers (4) that are randomly linked together.

A process for producing absorbent materials includes reducing a banana tree stalk into separated fibers, pressing the separated fibers to generate pressed fibers having less than 50% moisture content by weight, reducing moisture content of the pressed fibers by applying infrared heating to produce pre-dried fibers, and applying a non-thermal drying process to generate dried fibers having less than 10% moisture content by weight for employment in an absorbent material that absorbs hydrocarbons.

The present disclosure relates, according to some embodiments, to methods and systems for deriving odor- and moisture-absorbing products from a microcrop (e.g., photosynthetic aquatic species). More specifically, the present disclosure relates, in some embodiments, to forming an absorptive product from Lemna, including an animal litter, an animal bedding, a diaper product, a spill clean-up product, and any combination thereof. A process for forming an absorbent product from a microcrop may comprise the actions of (a) lysing the microcrop to generate a lysed microcrop; (b) separating the lysed microcrop into a solid fraction and a juice fraction; (c) processing the solid fraction to generate an absorbent solid; and/or (d) forming, by a shaping unit, the absorbent solid into pellets or granules that may be incorporated into the absorptive product. An absorptive product may have odor-reducing properties that are due in part to chlorophyll (e.g., from a microcrop).

Biogenic activated carbon compositions disclosed herein comprise at least 55 wt % carbon, some of which may be present as graphene, and have high surface areas, such as Iodine Numbers of greater than 2000. Some embodiments provide biogenic activated carbon that is responsive to a magnetic field. A continuous process for producing biogenic activated carbon comprises countercurrently contacting, by mechanical means, a feedstock with a vapor stream comprising an activation agent including water and/or carbon dioxide; removing vapor from the reaction zone; recycling at least some of the separated vapor stream, or a thermally treated form thereof, to an inlet of the reaction zone(s) and/or to the feedstock; and recovering solids from the reaction zone(s) as biogenic activated carbon. Methods of using the biogenic activated carbon are disclosed.

A tray has an integral inner layer having an inner surface and an exterior surface. The inner layer has a substantially planar base portion and a wall portion extending upwardly from at least a portion of a perimeter of the base portion. An outer layer applied to the exterior surface of the inner layer comprises a liquid-impermeable coating. The inner layer consists of an absorbent paperboard, and the outer layer is adapted to inhibit liquid absorbed in the inner layer from leaking through the tray. The tray may be useful in the retail display of meat or produce.

A superheated steam generating apparatus (12) is made of a material capable of generating heat upon energization. The superheated steam generating apparatus (12) comprises a superheated steam generating pipe (12) which includes a flow path (129) in which steam can flow and transfers the heat to the steam in the flow path (129) to generate superheated steam. In the superheated steam generating apparatus (12), a length of a cross-sectional shape of a wall forming the flow path (129) of the superheated steam generating pipe (12) is longer than a length of a circumference of an exact circle having a same sectional area as a sectional area of the flow path (129).

Separation methods based on electrophoresis or chromatography that use a stationary phase including fibril cellulose.

A method for producing charcoal particles or pellets which use different additives as binders for the biochar pellets. The method includes producing a mixture with charcoal and additives selected from nanocrystalline cellulose, nanocrystalline fibrils, bentonite, and polyvinyl acetate. The mixture is created by mixing one or more of the additives with charcoal or bentonite. The mixture is then processed in a pelletizer device. While processing, the surface of the mixture is sprayed with a liquid. Once turned into pellets by way of the pelletizer device, the resulting pellets are then dried by applying heat to the pellets. The liquid can be water or a solution of water and sodium borate.
