Abstract: This invention discloses adhesive compositions useful for providing cohesive strength to particles, for example a mat of wood particles produced while making particleboard prior to curing. The adhesive compositions has a) one or more biopolymers and b) one or more monomers or oligomers. An oligomer may have a degree of polymerization of 4 or less. The weight ratio of the monomer/oligomer to the biopolymer is optionally between 30:70 and 80:20. Optionally, the adhesive compositions may be combined with an isocyanate. The adhesive composition may be used to make no added formaldehyde wood composites such as particleboard.

Abstract: The present invention relates to a method for treating sticky cotton aimed at reducing the stickiness of thereby treated cotton fibers. Said method comprises the following steps: a. sowing said cotton fibers with bacteria, by spraying, preferably by uniformly spraying an aqueous suspension of said bacteria, so as to achieve a maximum resulting humidity thereof of 16%; b. storing the thereby treated cotton fibers as a compressed bale; c. letting the sown bacteria act at notably room temperature for at least about one week.
