A pallet wrap system and manufacture for repair of wood pallets that extends the service life of wood pallets to reduce associated costs, environmental concerns, and workplace injuries. The wrap or wrap component comprises a plurality of portions hingedly attached to one another and configured to surround or cover a portion of a pallet. The wrap component may be manufactured using recycled material, such as paper, aluminum, or plastic, and may further include a chemical for properties such as elasticity, adhesion, and bonding grip. The wrap component may further be folded to such that it can be erected from a flattened state to form a display unit for products. The wrap may include printed information content such as advertising/marketing content, or manufacturer's or shipper's information, identification or logo to make sure that only that business' product is shipped or used with the identified pallet.

Presented and described is a method for reclaiming thermoplastic materials intended for recycling, such as, for example, polyethylene terephthalate (PET), in the form of flakes. According to the invention, in a first step, the flakes are exposed to an oxidative fluid and heat until contaminated flakes are modified such that, in a second step, they are separated from the remaining flakes as a result of this modification.

A method for separating a fraction of super-absorbent polymers (SAP) from post-consumer absorbent sanitary products, said post-consumer absorbent sanitary products further including at least one cellulose fraction and one plastic fraction. The method includes the steps of sterilizing the post-consumer absorbent sanitary products and treating said post-consumer absorbent sanitary products by immersion in a bath with an aqueous solution containing at least one oxidizing compound. The oxidizing compound is preferably selected from the group consisting of sodium persulfate, potassium persulfate, ammonium persulfate, potassium monopersulfate, and hydrogen peroxide; preferably hydrogen peroxide. The treatment by immersion allows cross-link cleavage and solubilizing of the SAP contained in said post-consumer absorbent sanitary products, and obtaining a suspension comprising i) a solid fraction and ii) a liquid fraction, wherein the liquid fraction comprises linear polyacrylate derived from the cross-link cleavage and solubilization of SAP.
