AI Technical Summary
Technical Problem
Existing paper pulp-based pallets suffer from low strength and hydrophilicity, making them unsuitable for widespread industrial application.
Method used
A composite material is created by combining cellulose fibers with a hydrophobic component such as hydrogenated oils or fats, which is introduced into the pulp through a soaking process, significantly enhancing the strength and water resistance of the pallets.
Benefits of technology
The composite pallets exhibit a two-fold increase in buckling strength and can withstand water for four weeks, compared to less than an hour for traditional paper pulp pallets, while also being lightweight and fully recyclable.

Abstract
A composite transport pallet comprises a composite of cellulose fiber material and a hydrophobic component. The composite material is a preferably two-material composite where the matrix comprises in the range of 10-40 wt% hydrophobic component selected from wax and hydrogenated oils and fats and the reinforcement is moulded cellulose fiber pulp. The hydrophobic component can comprise various forms of hydrogenated vegetable oils, hydrogenated fats, waxes like oil-based paraffin waxes and vegetable waxes and optionally also polymers.
