Abstract
Provided herein are composite materials comprising at least 70 wt. % thermally consolidated recovered paper and plastic fragments and less than 5,000 ng water-soluble endotoxin per gram of composite materials, as well as methods of preparing said composite materials and methods of sanitizing recovered waste materials.
Claims20
A composite material comprising about 70 wt. % to about 99 wt. % of thermally consolidated recovered paper and plastic fragments, about 0.01 wt. % to about 0.40 wt. % of polymerization product of a multifunctional aldehyde, and about 0.0001 wt. % to about 0.02 wt. % of cross-linked endotoxin.
A method to prepare a composite material, the method comprising:
- compressing and heating a mixture comprising paper fragments or plastic fragments, or a combination thereof, and a multifunctional aldehyde to form the composite material;
- wherein the composite material comprises polymerization product of the multifunctional aldehyde;
- cross-linked endotoxin;
- and at least about 70 wt. % of the paper fragments or the plastic fragments, or the combination thereof.
A method to sanitize recovered waste materials, the method comprising:
- treating a mixture comprising recovered waste materials with a multifunctional aldehyde to obtain the sanitized recovered waste materials,
- wherein the recovered waste materials comprise gram-negative bacteria;
- and
- wherein the sanitized recovered waste materials comprise polymerization product of the multifunctional aldehyde and cross-linked endotoxin.
