A method of manufacturing the composite material includes preparing a mixture comprising the absorptive polymer and water and distributing the exfoliated clay, chromogenic indicator and oxidizing agent within the mixture, preferably by extrusion and addition of the components at particular points in processing the polymer mixture.

Abstract: A process for producing unsaturated and saturated free fatty acid from trap oils, trap greases, brown greases and grease trap waste as starting material. The process consist in subjecting the starting material to a pretreatment, a first purification step, a fractional step, a second purification step and eventually a hydrogenation step. Methyl esters of unsaturated and saturated free fatty acids, oleic acid and stearin is obtained from this process.

Abstract: A process for producing microcrystalline cellulose. The process comprising the following steps: a) preparation of a pulp by repulping, b) pressing of the pulp obtained in a), c) decompaction of the pulp obtained in b), d) feeding of the pulp obtained in c) into a pre-heated reactor, e) cooking of the pulp at a temperature, a time and a pressure allowing to obtain a pulp having a desired degree of polymerization, f) cooling and partial controlled depressurization of the reactor by purging the reactor, followed by a water injection into the jacket and directly into the reactor, g) filtering the pulp obtained in f), h) bleaching of the pulp obtained in g), and i) drying the pulp obtained in h). The process allows the application of a controlled depressurization in step f), which in turn allows to keep the natural texture of the fibers and to obtain a cellulose having a low degree of polymerization.
