Methods use a catalytic composition built up from a ceramic material including a catalytic material and a first inorganic binder and a second inorganic binder and a catalytic structure made thereof. Preferably, the structure is made by a colloidal ceramic shaping technique. The structure is used for catalytic or ion exchange applications. The catalytic structures have excellent mechanical, physicochemical and catalytic properties.

Preparation of low-dusting or dust-free waterdispersible crosslinked polyvinylpyrrolidone (PVPP) granules characterized by extruding a dough consisting of said PVPP and water through a die plate and subsequent drying of the granules.

Technologies are described for a method of making an encapsulated reactant having a desired shape or size. The method comprises providing solid reactant particles and an encapsulating material. The encapsulating material is heated above its solidification temperature to form a molten, semi-solid, or liquid encapsulating material. The solid reactant particles are added to the molten, semi-solid, or liquid encapsulating material and mixed to disperse the solid reactant particles in the encapsulating material and form a mixture. The mixture may be extruded or formed into the desired shape or size of the encapsulated reactant, or the mixture may be solidified and extruded, granulated, shredded, ground, or pressed into the desired shape or size.

A composition that includes plant derived wax having a melting point of at least 70° C. can be used to waterproof cellulose based materials like paper and board. Suitable waxes include sugarcane wax and rice-bran wax. A surfactant such as stearic acid improves the adhesion of the composition to the underlying material. The resulting waterproof laminate can be economically recycled. Hot beverage cups made from the laminate are waterproof and recyclable without first being separated into components. Coffee pods and drinking straws that are waterproof and recyclable are manufactured with the waterproof laminate.
